PREFACE

It was while sitting in his hay-barn study in the Catskills and looking out upon the maple woods of the old home farm, and under the maples at Riverby, that the most of these essays were written, during the last two years of the author's life. And it was to the familiar haunts near his Hudson River home that his thoughts wistfully turned while wintering in Southern California in 1921. As he pictured in his mind the ice breaking up on the river in the crystalline March days, the return of the birds, the first hepaticas, he longed to be back among them; he was there in spirit, gazing upon the river from the summer-house, or from the veranda of the Nest, or seated at his table in the chestnut-bark Study, or busy with his sap-gathering and sugar-making.

Casting about for a title for this volume, the vision of maple-trees and dripping sap and crisp March days playing constantly before his mind, one day while sorting and shifting the essays for his new book, he suddenly said, "I have it! We'll call it Under the Maples!"

His love for the maple, and consequently his pleasure in having hit upon this title, can be gathered from the following fragment found among his miscellaneous notes: "I always feel at home where the sugar maple grows It was paramount in the woods of the old home farm where I grew up. It looks and smells like home. When I bring in a maple stick to put on my fire, I feel like caressing it a little. Its fiber is as white as a lily, and nearly as sweet-scented. It is such a tractable, satisfactory wood to handle—a clean, docile, wholesome tree; burning without snapping or sputtering, easily worked up into stovewood, fine of grain, hard of texture, stately as a forest tree, comely and clean as a shade tree, glorious in autumn, a fountain of coolness in summer, sugar in its veins, gold in its foliage, warmth in its fibers, and health in it the year round."

THE FALLING LEAVES

The time of the falling of leaves has come again. Once more in our morning walk we tread upon carpets of gold and crimson, of brown and bronze, woven by the winds or the rains out of these delicate textures while we slept.

How beautifully the leaves grow old! How full of light and color are their last days! There are exceptions, of course. The leaves of most of the fruit-trees fade and wither and fall ingloriously. They bequeath their heritage of color to their fruit. Upon it they lavish the hues which other trees lavish upon their leaves. The pear-tree is often an exception. I have seen pear orchards in October painting a hillside in hues of mingled bronze and gold. And well may the pear-tree do this, it is so chary of color upon its fruit.

But in October what a feast to the eye our woods and groves present! The whole body of the air seems enriched by their calm, slow radiance. They are giving back the light they have been absorbing from the sun all summer.

The carpet of the newly fallen leaves looks so clean and delicate when it first covers the paths and the highways that one almost hesitates to walk upon it. Was it the gallant Raleigh who threw down his cloak for Queen Elizabeth to walk upon? See what a robe the maples have thrown down for you and me to walk upon! How one hesitates to soil it! The summer robes of the groves and the forests—more than robes, a vital part of themselves, the myriad living nets with which they have captured, and through which they have absorbed, the energy of the solar rays. What a change when the leaves are gone, and what a change when they come again! A naked tree may be a dead tree. The dry, inert bark, the rough, wirelike twigs change but little from summer to winter. When the leaves come, what a transformation, what mobility, what sensitiveness, what expression! Ten thousand delicate veined hands reaching forth and waving a greeting to the air and light, making a union and compact with them, like a wedding ceremony. How young the old trees suddenly become! what suppleness and grace invest their branches! The leaves are a touch of immortal youth. As the cambium layer beneath the bark is the girdle of perennial youth, so the leaves are the facial expression of the same quality. The leaves have their day and die, but the last leaf that comes to the branch is as young as the first. The leaves and the blossom and the fruit of the tree come and go, yet they age not; under the magic touch of spring the miracle is repeated over and over.

The maples perhaps undergo the most complete transformation of all the forest trees. Their leaves fairly become luminous, as if they glowed with inward light. In October a maple-tree before your window lights up your room like a great lamp. Even on cloudy days its presence helps to dispel the gloom. The elm, the oak, the beech, possess in a much less degree that quality of luminosity, though certain species of oak at times are rich in shades of red and bronze. The leaves of the trees just named for the most part turn brown before they fall. The great leaves of the sycamore assume a rich tan-color like fine leather.

The spider weaves a net out of her own vitals with which to capture her prey, but the net is not a part of herself as the leaf is a part of the tree. The spider repairs her damaged net, but the tree never repairs its leaves. It may put forth new leaves, but it never essays to patch up the old ones. Every tree has such a superabundance of leaves that a few more or less or a few torn and bruised ones do not seem to matter. When the leaf surface is seriously curtailed, as it often is by some insect pest, or some form of leaf-blight, or by the ravages of a hail-storm, the growth of the tree and the maturing of its fruit is seriously checked. To denude a tree of its foliage three years in succession usually proves fatal. The vitality of the tree declines year by year till death ensues.

To me nothing else about a tree is so remarkable as the extreme delicacy of the mechanism by which it grows and lives, the fine hairlike rootlets at the bottom and the microscopical cells of the leaves at the top. The rootlets absorb the water charged with mineral salts from the soil, and the leaves absorb the sunbeams from the air. So it looks as if the tree were almost made of matter and spirit, like man; the ether with its vibrations, on the one hand, and the earth with its inorganic compounds, on the other—earth salts and sunlight. The sturdy oak, the gigantic sequoia, are each equally finely organized in these parts that take hold upon nature. We call certain plants gross feeders, and in a sense they are; but all are delicate feeders in their mechanism of absorption from the earth and air.

The tree touches the inorganic world at the two finest points of its structure—the rootlets and the leaves. These attack the great crude world of inorganic matter with weapons so fine that only the microscope can fully reveal them to us. The animal world seizes its food in masses little and big, and often gorges itself with it, but the vegetable, through the agency of the solvent power of water, absorbs its nourishment molecule by molecule.

A tree does not live by its big roots—these are mainly for strength and to hold it to the ground. How they grip the rocks, fitting themselves to them, as Lowell says, like molten metal! The tree's life is in the fine hairlike rootlets that spring from the roots. Darwin says those rootlets behave as if they had minute brains in their extremities. They feel their way into the soil; they know the elements the plant wants; some select more lime, others more potash, others more magnesia. The wheat rootlets select more silica to make the stalk; the pea rootlets select more lime: the pea does not need the silica. The individuality of plants and trees in this respect is most remarkable. The cells of each seem to know what particular elements they want from the soil, as of course they do.

The vital activity of the tree goes on at three points—in the leaves, in the rootlets, and in the cambium layer. The activity of the leaf and rootlet furnishes the starchy deposit which forms this generative layer—the milky, mucilaginous girdle of matter between the outer bark and the wood through which the tree grows and increases in size. Generation and regeneration take place through this layer. I have called it the girdle of perpetual youth. It never grows old. It is annually renewed. The heart of the old apple-tree may decay and disappear, indeed the tree may be reduced to a mere shell and many of its branches may die and fall, but the few apples which it still bears attest the fact that its cambium layer, at least over a part of its surface, is still youthful and doing its work. It is this layer that the yellow-bellied woodpecker, known as the sapsucker, drills into and devours, thus drawing directly upon the vitality of the tree. But his ravages are rarely serious. Only in two instances have I seen dead branches on an apple-tree that appeared to be the result of his drilling.

What we call the heart of a tree is in no sense the heart; it has no vital function, but only the mechanical one of strength and support. It adds to the tree's inertia and power to resist storms. The trunk of a tree is like a community where only one generation at a time is engaged in active business, the great mass of the population being retired and adding solidity and permanence to the social organism. The rootlets of a plant or a tree are like the laborers in the field that produce for us the raw material of our food, while the leaves are like our many devices for rendering it edible and nourishing. The rootlets continue their activity in the fall, after the leaves have fallen, and thus gorge the tree with fluid against the needs of the spring. In the growing tree or vine the sap, charged with nourishment, flows down from the top to the roots. In the spring it evidently flows upward, seeking the air through the leaves. Or rather, we may say that the crude sap always flows upward, while the nutritive sap flows downward, thus giving the tree a kind of double circulation.

A tree may be no more beautiful and wonderful when we have come to a knowledge of all its hidden processes, but it certainly is no less so. We do not think of the function of the leaves, nor of the bark, nor of the roots and rootlets, when we gaze upon a noble oak or an elm; we admire it for its form, its sturdiness, or its grace; it is akin to ourselves; it is the work of a vast community of cells like those that build up our own bodies; it is a fountain of living matter rising up out of the earth and splitting up and spreading out at its top in a spray of leaves and flowers; and if we could see its hidden processes we should realize how truly like a fountain it is. While in full leaf a current of water is constantly flowing through it, and flowing upward against gravity. This stream of water is truly its life current; it enters at the rootlets under the ground and escapes at the top through the leaves by a process called transpiration. All the mineral salts with which the tree builds up its woody tissues,—its osseous system, so to speak,—the instruments with which it imprisons and consolidates the carbon which it obtains from the air, are borne in solution in this stream of water. Its function is analogous to that of the rivers which bring the produce and other material to the great cities situated upon their banks. A cloud of invisible vapor rises from the top of every tree and a thousand invisible rills enter it through its myriad hairlike rootlets. The trees are thus conduits in the circuit of the waters from the earth to the clouds. Our own bodies and the bodies of all living things perform a similar function. Life cannot go on without water, but water is not a food; it makes the processes of metabolism possible; assimilation and elimination go on through its agency. Water and air are the two ties between the organic and the inorganic. The function of the one is mainly mechanical, that of the other is mainly chemical.

As the water is drawn in at the roots, it flows out at the top, to which point it rises by capillary attraction and a process called osmosis. Neither of them is a strictly vital process, since both are found in the inorganic world; but they are in the service of what we call a vital principle. Some physicists and biochemists laugh at the idea of a vital principle. Huxley thought we might as well talk about the principle of aqueosity in water. We are the victims of words. The sun does not shoot out beams or rays, though the eye reports such; but it certainly sends forth energy; and it is as certain that there is a new activity in matter—some matter—that we call vital.

Matter behaves in a new manner; builds up new compounds and begets myriads of new forms not found in the inorganic world, till it finally builds up the body and mind of man. Death puts an end to this activity alike in man and tree, and a new kind of activity sets in—a disorganizing activity, still with the aid of water and air and living organisms. It is like the compositor distributing his type after the book is printed. The micro-organisms answer to the compositor, but they are of a different kind from those which build up the body in the first instance. But the living body as a whole, with its complex of coördinating organs and functions—what attended to that? The cells build the parts, but what builds the whole?

How many things we have in common with the trees! The same mysterious gift of life, to begin with; the same primary elements—carbon, nitrogen, oxygen, and so on—in our bodies; and many of the same vital functions—respiration, circulation, absorption, assimilation, reproduction. Protoplasm is the basis of life in both, and the cell is the architect that builds up the bodies of both. Trees are rooted men and men are walking trees. The tree absorbs its earth materials through the minute hairs on its rootlets, called fibrillæ, and the animal body absorbs its nutriment through analogous organs in the intestines, called lacteals.

Whitman's expression "the slumbering and liquid trees" often comes to my mind. They are the words of a poet who sees hidden relations and meanings everywhere. He knows how fluid and adaptive all animate nature is. The trees are wrapped in a kind of slumber in winter, and they are reservoirs of living currents in summer. If all living bodies came originally out of the sea, they brought a big dower of the sea with them. The human body is mainly a few pinches of earth salts held in solution by several gallons of water. The ashes of the living tree bulk small in comparison with the amount of water it holds. Yes, "the slumbering and liquid trees." They awaken from their slumber in the spring, the scales fall from their buds, the fountains within them are unsealed, and they again become streams of living energy, breaking into leaf and bloom and fruit under the magic of the sun's rays.

THE PLEASURES OF A NATURALIST

I

How closely every crack and corner of nature is packed with life, especially in our northern temperate zone! I was impressed with this fact when during several June days I was occupied with road-mending on the farm where I was born. To open up the loosely piled and decaying laminated rocks was to open up a little biological and zoölogical museum, so many of our smaller forms of life harbored there. From chipmunks to ants and spiders, animal life flourished. We disturbed the chipmunks in their den a foot and a half or more beneath the loosely piled rocks. There were two of them in a soft, warm nest of dry, shredded maple-leaves. They did not wait to be turned out of doors, but when they heard the racket overhead bolted precipitately. Two living together surprised me, as heretofore I had never known but one in a den. Near them a milk snake had stowed himself away in a crevice, and in the little earthquake which we set up got badly crushed. Two little red-bellied snakes about one foot long had also found harbor there.

The ants rushed about in great consternation when their eggs were suddenly exposed. In fact, there was live natural history under every stone about us. Some children brought me pieces of stone, which they picked up close by, which sheltered a variety of cocoon-building spiders. One small, dark-striped spider was carrying about its ball of eggs, the size of a large pea, attached to the hind part of its body. This became detached, when she seized it eagerly and bore it about held between her legs. Another fragment of stone, the size of one's hand, sheltered the chrysalis of some species of butterfly which was attached to it at its tail. It was surprising to see this enshrouded creature, blind and deaf, wriggle and thrash about as if threatening us with its wrath for invading its sanctuary. One would about as soon expect to see an egg protest.

Thus the naturalist finds his pleasures everywhere. Every solitude to him is peopled. Every morning or evening walk yields him a harvest to eye or ear.

The born naturalist is one of the most lucky men in the world. Winter or summer, rain or shine, at home or abroad, walking or riding, his pleasures are always near at hand. The great book of nature is open before him and he has only to turn the leaves.

A friend sitting on my porch in a hickory rocking-chair the other day was annoyed by one of our small solitary wasps that seemed to want to occupy the chair. It held a small worm in its legs. She would "shoo" it away, only to see it back in a few seconds. I assured her that it did not want to sting her, but that its nest was somewhere in the chair. And, sure enough, as soon as she quieted down, it entered a small opening in the end of one of the chair arms, and deposited its worm, and presently was back with another, and then a third and a fourth; and before the day was done it came with little pellets of mud and sealed up the opening.

II

My morning walk up to the beech wood often brings me new knowledge and new glimpses of nature. This morning I saw a hummingbird taking its bath in the big dewdrops on a small ash-tree. I have seen other birds bathe in the dew or raindrops on tree foliage, but did not before know that the hummer bathed at all.

I also discovered that the webs of the little spiders in the road, when saturated with moisture, as they were from the early fog this morning, exhibit prismatic tints. Every thread of the web was strung with minute spherules of moisture, and they displayed all the tints of the rainbow. In each of them I saw one abutment of a tiny rainbow. When I stepped a pace or two to the other side, I saw the other abutment. Of course I could not see the completed bow in so small an area. These fragments are as unapproachable as the bow in the clouds. I also saw that where a suspended dewdrop becomes a jewel, or displays rainbow tints, you can see only one at a time—to the right or left of you. It also is a fragment of a rainbow. Those persons who report beholding a great display of prismatic effects in the foliage of trees, or in the grass after a shower, are not to be credited. You may see the drops glistening in the sun like glass beads, but they will not exhibit prismatic tints. In only one at a time will you see rainbow tints. Change your position, and you may see another, but never a great display of prismatic tints at one time.

In my walk the other morning I turned over a stone, looking for spiders and ants. These I found, and in addition there were two cells of one of our solitary leaf-cutters, which we as boys called "sweat bees," because they came around us and would alight on our sweaty hands and arms as if in quest of salt, as they probably were. It is about the size of a honey bee, of lighter color, and its abdomen is yellow and very flexible. It carries its pollen on its abdomen and not upon its thighs. These cells were of a greenish-brown color; each of them was like a miniature barrel in which the pollen with the egg of the bee was sealed up. When the egg hatches, the grub finds a loaf of bread at hand for its nourishment. These little barrels were each headed up with a dozen circular bits of leaves cut as with a compass, exactly fitting the cylinder, one upon the other. The wall of the cylinder was made up of oblong cuttings from leaves, about half an inch wide, and three quarters of an inch long, a dozen of them lapped over one another, and fitted together in the most workmanlike manner.

In my boyhood I occasionally saw this bee cutting out her nesting-material. Her mandibles worked like perfect shears. When she had cut out her circular or her oblong patches, she rolled them up, and, holding them between her legs, flew away with them. I have seen her carry them into little openings in old rails, or old posts. About the period of hatching, I do not know.

III

Swallows, in hawking through the air for insects, do not snap their game up as do the true flycatchers. Their mouths are little nets which they drive through the air with the speed of airplanes. A few mornings ago the air was cold, but it contained many gauzy, fuzzy insects from the size of mosquitoes down to gnats. They kept near the ground. I happened to be sitting on the sunny side of a rock and saw the swallows sweep past. One came by within ten feet of me and drove straight on to a very conspicuous insect which disappeared in his open mouth in a flash. How many hundreds or thousands of such insects they must devour each day! Then think of how many insects the flycatchers and warblers and other insect-eating birds must consume in the course of a season!

IV

We little suspect how the woods and wayside places swarm with life. We see little of it unless we watch and wait. The wild creatures are cautious about revealing themselves: their enemies are on the lookout for them. Certain woods at night are alive with flying squirrels which, except for some accident, we never see by day. Then there are the night prowlers—skunks, foxes, coons, minks, and owls—yes, and mice.

The wild mice we rarely see. The little shrew mole, which I know is active at night, I have never seen but once. I once set a trap, called the delusion trap, in the woods by some rocks where I had no reason to suspect there were more mice than elsewhere, and two mornings later it was literally packed full of mice, half a dozen or more.

Turn over a stone in the fields and behold the consternation among the small folk beneath it,—ants, slugs, bugs, worms, spiders,—all objecting to the full light of day, not because their deeds are evil, but because the instinct of self-preservation prompts this course. As I write these sentences, a chipmunk, who has his den in the bank by the roadside near by, is very busy storing up some half-ripe currants which grew on a bush a few yards away. Of course the currants will ferment and rot, but that consideration does not disturb him; the seeds will keep, and they are what he is after. In the early summer, before any of the nuts and grains are ripened, the high cost of living among the lesser rodents is very great, and they resort to all sorts of makeshifts.

V

In regard to this fullness of life in the hidden places of nature, Darwin says as much of the world as a whole:

Well may we affirm that every part of the world is inhabitable. Whether lakes of brine or those subterranean ones hidden beneath volcanic mountains—warm mineral springs—the wide expanse and depth of the ocean, the upper regions of the atmosphere, and even the surface of perpetual snow—all support organic beings.

Never before was there such a lover of natural history as Darwin. In the earth, in the air, in the water, in the rocks, in the sand, in the mud—he scanned the great biological record of the globe as it was never scanned before. During the voyage of the Beagle he shirked no hardships to add to his stores of natural knowledge. He would leave the comfortable ship while it was making its surveys, and make journeys of hundreds of miles on horseback through rough and dangerous regions to glean new facts. Grass and water for his mules, and geology or botany or zoölogy or anthropology for himself, and he was happy. At a great altitude in the Andes the people had shortness of breath which they called "puna," and they ate onions to correct it. Darwin says, with a twinkle in his eye, "For my part I found nothing so good as the fossil shells."

His Beagle voyage is a regular magazine of natural-history knowledge. Was any country ever before so searched and sifted for its biological facts? In lakes and rivers, in swamps, in woods, everywhere his insatiable eye penetrated. One re-reads him always with a different purpose in view. If you happen to be interested in insects, you read him for that; if in birds, you read him for that; if in mammals, in fossils, in reptiles, in volcanoes, in anthropology, you read him with each of these subjects in mind. I recently had in mind the problem of the soaring condor, and I re-read him for that, and, sure enough, he had studied and mastered that subject, too. If you are interested in seeing how the biological characteristics of the two continents, North and South America, agree or contrast with each other, you will find what you wish to know. You will learn that in South America the lightning-bugs and glowworms of many kinds are the same as in North America; that the beetle, or elator, when placed upon its back, snaps itself up in the air and falls upon its feet, as our species does; that the obscene fungus, or Phallus, taints the tropical forests, as a similar species at times taints our dooryards and pasture-borders; and that the mud-dauber wasps stuff their clay cells with half-dead spiders for their young, just as in North America. Of course there are new species of animal and plant life, but not many. The influence of environment in modifying species is constantly in his mind.

VI

The naturalist can content himself with a day of little things. If he can read only a word of one syllable in the book of nature, he will make the most of that. I read such a word the other morning when I perceived, when watching a young but fully fledged junco, or snowbird, that its markings Were like those of the vesper sparrow. The young of birds always for a brief period repeat the markings of the birds of the parent stem from which they are an offshoot. Thus, the young of our robins have speckled breasts, betraying their thrush kinship. And the young junco shows, in its striped appearance of breast and back, and the lateral white quills in the tail, its kinship to the grass finch or vesper sparrow. The slate-color soon obliterates most of these signs, but the white quills remain. It has departed from the nesting-habits of its forbears. The vesper sparrow nests upon the ground in the open fields, but the junco chooses a mossy bank or tussock by the roadside, or in the woods, and constructs a very artistic nest of dry grass and hair which is so well hidden that the passer-by seldom detects it.

Another small word I read about certain of the rocks in my native Catskills, a laminated, blue-gray sandstone, that when you have split them open with steel wedges and a big hammer, or blown them up with dynamite, instead of the gray fresh surface of the rock greeting you, it is often a surface of red mud, as if the surface had been enameled or electrotyped with mud. It appears to date from the first muddy day of creation. I have such a one for my doorstone at Woodchuck Lodge. It is amusing to see the sweepers and scrubbers of doorstones fall upon it with soap and hot water, and utterly fail to make any impression upon it. Nowhere else have I seen rocks casehardened with primal mud. The fresh-water origin of the Catskill rocks no doubt in some way accounts for it.

VII

We are all interested students of the weather, but the naturalist studies it for some insight into the laws which govern it. One season I made my reputation as a weather prophet by predicting on the first day of December a very severe winter. It was an easy guess. I saw in Detroit a bird from the far north, a bird I had never before seen, the Bohemian waxwing, or chatterer. It breeds above the Arctic Circle and is common to both hemispheres. I said, When the Arctic birds come down, be sure there is a cold wave behind them. And so it proved.

When the birds fail to give one a hint of the probable character of the coming winter, what reliable signs remain? These remain: When December is marked by sudden and violent extremes of heat and cold, the winter will be broken; the cold will not hold. I have said elsewhere that the hum of the bee in December is the requiem of winter. But when the season is very evenly spaced, the cold slowly and steadily increasing through November and December, no hurry, no violence, then be prepared for a snug winter.

As to wet and dry summers, one can always be guided by the rainfall on the Pacific coast; a shortage on the western coast means an excess on the eastern. For four or five years past California has been short of its rainfall; so much so that quite general alarm is felt over the gradual shrinkage of their stored-up supplies, the dams and reservoirs; and during the summer seasons the parts of New England and New York with which I am acquainted have had very wet seasons—floods in midsummer, and full springs and wells at all times. The droughts have been temporary and local.

We say, "As fickle as the weather," but the meteorological laws are pretty well defined. All signs fail in a drought, and all signs fail in a wet season. At one time the south wind brings no rain, at another time the north and northwest winds do bring rain. The complex of conditions over a continental area of rivers and lakes and mountain-chains is too vast for us to decipher; it inheres in the nature of things. It is one of the potencies and possibilities which matter possesses. We can take no step beyond that.

VIII

There seems to me to be false reasoning in the argument from analogy which William James uses in his lectures on "Human Immortality." The brain, he admits, is the organ of the mind, but may only sustain the relation to it, he says, which the wire sustains to the electric current which it transmits, or which the pipe sustains to the water which it conveys.

Now the source and origin of the electric current is outside the wire that transmits it, and it could sustain no other than a transient relation to any outside material through which it passed. But if we know anything, we know that the human mind or spirit is a vital part of the human body; its source is in the brain and nervous system; hence, it and the organ through which it is manifested are essentially one.

The analogy of the brain to the battery or dynamo in which the current originates is the only logical or permissible one.

IX

Maeterlinck wrote wisely when he said:

The insect does not belong to our world. The other animals, the plants even, notwithstanding their dumb life, and the great secrets which they cherish, do not seem wholly foreign to us. In spite of all we feel a sort of earthly brotherhood with them.... There is something, on the other hand, about the insect that does not belong to the habits, the ethics, the psychology of our globe. One would be inclined to say that the insect comes from another planet, more monstrous, more energetic, more insane, more atrocious, more infernal than our own.

Certainly more cruel and monstrous than our own. Among the spiders, for instance, the female eats the male and often devours her own young. The scorpion does the same thing. I know of nothing like it among our land animals outside the insect world.

The insects certainly live in a wonderland of which we have little conception. All our powers are tremendously exaggerated in these little people. Their power makes them acquainted with the inner molecular constitution of matter far more intimately than we can attain to by our coarse chemical analysis. Our world is agitated by vibrations, coarse and fine, of which our senses can take in only the slower ones. If they exceed three thousand a second, they become too shrill for our ears. It is thought that the world of sound with the insects begins where ours leaves off. The drums and tubes of insects' ears are very minute. What would to us be a continuous sound is to them a series of separate blows. We begin to hear blows as continuous sounds when they amount to about thirty a second. The house-fly has about four thousand eye-lenses; the cabbage butterfly, and the dragon-fly, about seventeen thousand; and some species of beetles have twenty-five thousand. We cannot begin to think in what an agitated world the insect lives, thrilling and vibrating to a degree that would drive us insane. If we possessed the same microscopic gifts, how would the aspect of the world be changed! We might see a puff of smoke as a flock of small blue butterflies, or hear the hum of a mosquito as the blast of a trumpet. On the other hand, so much that disturbs us must escape the insects, because their senses are too fine to take it in. Doubtless they do not hear the thunder or feel the earthquake.

The insects are much more sensitive to heat and cold than we are, and for reasons. The number of waves in the ether that gives us the sensation of heat is three or four million millions a second. The number of tremors required to produce red light is estimated at four hundred and seventy-four million millions a second, and for the production of violet light, six hundred and ninety-nine million millions a second. No doubt the insects react to all these different degrees of vibration. Those marvelous instruments called antennæ seem to put them in touch with a world of which we are quite oblivious.

To how many things our lives have been compared!—to a voyage, with its storms and adverse currents and safe haven at last; to a day with its morning, noon, and night; to the seasons with their spring, summer, autumn, and winter; to a game, a school, a battle.

In one of his addresses to workingmen Huxley compared life to a game of chess. We must learn the names and the values and the moves of each piece, and all the rules of the game if we hope to play it successfully. The chessboard is the world, the pieces are the phenomena of the universe, the rules of the game are what we call the laws of nature. But it may be questioned if the comparison is a happy one. Life is not a game in this sense, a diversion, an aside, or a contest for victory over an opponent, except in isolated episodes now and then. Mastery of chess will not help in the mastery of life. Life is a day's work, a struggle where the forces to be used and the forces to be overcome are much more vague and varied and intangible than are those of the chessboard. Life is coöperation with other lives. We win when we help others to win. I suppose business is more often like a game than is life—your gain is often the other man's loss, and you deliberately aim to outwit your rivals and competitors. But in a sane, normal life there is little that suggests a game of any kind.

We must all have money, or its equivalent. There are the three things—money, goods, labor—and the greatest of these is labor. Labor is the sum of all values. The value of things is the labor it requires to produce or to obtain them. Were gold plentiful and silver scarce, the latter would be the more precious. The men at the plough and the hoe and in the mines of coal and iron stand first. These men win from nature what we all must have, and these things are none of them in the hands or under the guardianship of some one who is trying to keep us from obtaining them, or is aiming to take our aids and resources from us.

The chess simile has only a rhetorical value. The London workingmen to whom Huxley spoke would look around them in vain to find in their problems of life anything akin to a game of chess, or for any fruitful suggestion in the idea. They were probably mechanics, tradesmen, artisans, teamsters, boatmen, painters, and so on, and knew through experience the forces with which they had to deal. But how many persons who succeed in life have any such expert knowledge of the forces and conditions with which they have to deal, as two chess-players have of the pawns and knights and bishops and queens of the chessboard?

Huxley was nearly always impressive and convincing, and there was vastly more logical force in his figures than in those of most writers.

Life may more truly be compared to a river that has its source in a mountain or hillside spring, with its pure and sparking or foaming and noisy youth, then its quieter and stronger and larger volume, and then its placid and gently moving current to the sea. Blessed is the life that is self-purifying, like the moving waters; that lends itself to many noble uses, never breaking out of bonds and becoming a destructive force.

I had a letter the other day from a man who wanted to know why the meadow, or field, mice gnawed or barked the apple-trees when there was a deep coverlid of snow upon the ground. Was it because they found it difficult to get up through the deep, frozen snow to the surface to get seeds to eat? He did not seem to know that meadow mice are not seed-eaters, but that they live on grass and roots and keep well hidden beneath the ground during the day, when there is a deep fall of snow coming up out of their dens and retreats and leading a free holiday life beneath the snow, free from the danger of cats, foxes, owls, and hawks. Life then becomes a sort of picnic. They build new nests on the surface of the ground and form new runways, and disport themselves apparently in a festive mood. The snow is their protection. They bark the trees and take their time. When the snow is gone, their winter picnic is at an end, and they retreat to their dens in the ground and beneath flat stones, and lead once more the life of fear.

Sitting on my porch recently, wrapped in my blanket, recovering from a slight indisposition, I was in a mood to be interested in the everyday aspects of nature before me—in the white and purple lilacs, in the maple-leaves nearly full grown, in the pendent fringe of the yellowish-white bloom of the chestnut and oak, in the new shoots of the grapevines, and so forth. All these things formed only a setting or background for the wild life near by.

The birds are the little people that peep out at me, or pause and regard me curiously in this great temple of trees,—wrens, chippies, robins, bluebirds, catbirds, redstarts, and now and then rarer visitants. A few days earlier, for a moment, a mourning ground warbler suddenly appeared around the corner, on the ground, at the foot of the steps, and glanced hastily up at me. When I arose and looked over the railing, it had gone. Then the speckled Canada warbler came in the lilac bushes and syringa branches and gave me several good views. The bay-breasted warbler was reported in the evergreens up by the stone house, but he failed to report to me here at "The Nest." The female redstart, however, came several times to the gravel walk below me, evidently looking for material to begin her nest. And the wren, the irrepressible house wren, was and is in evidence every few minutes, busy carrying nesting-material into the box on the corner of the veranda. How intense and emphatic she is! And the male, how he throbs and palpitates with song! Yesterday an interloper appeared. He or she climbed the post by the back way, as it were, and hopped out upon the top of the box and paused, as if to see that the coast was clear. He acted as if he felt himself an intruder. Quick as a flash there was a brown streak from the branch of a maple thirty feet away, and the owner of the box was after him. The culprit did not stop to argue the case, but was off, hotly pursued. I must not forget the pair of wood thrushes that are building a nest in a maple fifty or more feet away. How I love to see them on the ground at my feet, every motion and gesture like music to the eye! The head and neck of the male fairly glows, and there is something fine and manly about his speckled breast.

A pair of catbirds have a nest in the barberry bushes at the south end of the house, and are in evidence at all hours. But when the nest is completed, and the laying of eggs begins, they keep out of the public eye as much as possible. From the front of the stage they retreat behind the curtain.

One day as I sat here I heard the song of the olive-backed thrush down in the currant-bushes below me. Instantly I was transported to the deep woods and the trout brooks of my native Catskills. I heard the murmuring water and felt the woodsy coolness of those retreats—such magic hath associative memories! A moment before a yellow-throated vireo sang briefly in the maple, a harsh note; and the oriole with its insistent call added to the disquieting sounds. I have no use for the oriole. He has not one musical note, and in grape time his bill is red, or purple, with the blood of our grapes.

But the most of these little people are my benefactors, and add another ray of sunshine to the May day. I shall not soon forget the spectacle of that rare little warbler peeping around the corner of the porch, like a little fairy, and then vanishing.

The mere studying of the birds, seeking mere knowledge of them, is not enough. You must live with the birds, so to speak; have daily and seasonal associations with them before they come to mean much to you. Then, as they linger about your house or your camp, or as you see them in your walks, they are a part of your life, and help give tone and color to your day.

THE FLIGHT OF BIRDS

To what widely different use birds put their power of flight! To the great mass of them it is simply a means of locomotion, of getting from one point to another. A small minority put their wing-power to more ideal uses, as the lark when he claps his wings at heaven's gate, and the ruffed grouse when he drums; even the woodcock has some other use for his wings than to get from one point to another. Listen to his flight song in the April twilight up against the sky.

Our small hawks use their power of flight mainly to catch their prey, as does the swallow skimming the air all day on tireless wing, but some of the other hawks, such as our red-tailed hawk, climb their great spirals apparently with other motives than those which relate to their daily fare. The crow has little other use for his wings than to gad about like a busy politician from one neighborhood to another. In Florida I have seen large flocks of the white ibis performing striking evolutions high up against the sky, evidently expressive of the gay and festive feeling begotten by the mating instinct.

The most beautiful flyer we ever see against our skies is the unsavory buzzard. He is the winged embodiment of grace, ease, and leisure. Judging from appearances alone, he is the most disinterested of all the winged creatures we see. He rides the airy billows as if only to enjoy his mastery over them. He is as calm and unhurried as the orbs in their courses. His great circles and spirals have a kind of astronomic completeness. That all this power of wing and grace of motion should be given to an unclean bird, to a repulsive scavenger, is one of the anomalies of nature. He does not need to hurry or conceal his approach; what he is after cannot flee or hide; he has no enemies; nothing wants him; and he is at peace with all the world.

The great condor of South America, in rising from the ground, always faces the wind. It is often captured by tempting it to gorge itself in a comparatively narrow space. But if a strong enough wind were blowing at such times, it could quickly rise over the barrier. Darwin says he watched a condor high in the air describing its huge circles for six hours without once flapping its wings. He says that, if the bird wished to descend, the wings were for a moment collapsed; and when again expanded, with an altered inclination, the momentum gained by the rapid descent seemed to urge the bird upwards with the even and steady movement of a paper kite. In the case of any bird soaring, its motion must be sufficiently rapid for the action of the inclined surface of its body on the atmosphere to counterbalance its gravity. The force to keep up the momentum of a body moving in a horizontal plane in the air (in which there is so little friction) cannot be great, and this force is all that is wanted. The movement of the neck and body of the condor, we must suppose, is sufficient for this. However this may be, it is truly wonderful and beautiful to see so great a bird, hour after hour, without any apparent exertion, wheeling and gliding over mountain and river.

The airplane has a propelling power in its motor, and it shifts its wings to take advantage of the currents. The buzzard and condor do the same thing. They are living airplanes, and their power is so evenly and subtly distributed and applied, that the trick of it escapes the eye. But of course they avail themselves of the lifting power of the air-currents.

All birds know how to use their wings to propel themselves through the air, but the mechanism of the act we may not be able to analyze. I do not know how a butterfly propels itself against a breeze with its quill-less wings, but we know that it does do it. As its wings are neither convex nor concave, like a bird's, one would think that the upward and downward strokes would neutralize each other; but they do not. Strong winds often carry them out over large bodies of water; but such a master flyer as the monarch beats its way back to shore, and, indeed, the monarch habitually flies long distances over salt water when migrating along our seacoast in spring and fall.

At the moment of writing these paragraphs, I saw a hen-hawk flap heavily by, pursued by a kingbird. The air was phenomenally still, not a leaf stirred, and the hawk was compelled to beat his wings vigorously. No soaring now, no mounting heavenward, as I have seen him mount till his petty persecutor grew dizzy with the height and returned to earth. But the next day, with a fairly good breeze blowing, I watched two hawks for many minutes climbing their spiral stairway to the skies, till they became very small objects against the clouds, and not once did they flap their wings! Then one of them turned toward the mountain-top and sailed straight into the face of the wind, till he was probably over his mate or young, when, with half-folded wings, he shot down into the tree-tops like an arrow.

In regard to powers of flight, the birds of the air may be divided into three grand classes: those which use their wings simply to transport themselves from one place to another,—the same use we put our legs to,—those which climb the heavens to attain a wide lookout, either for the pleasure of soaring, or to gain a vantage-point from which to scan a wide territory in search of food or prey, and those which feed as they fly. Most of our common birds are examples of the first class. Our hawks and buzzards are examples of the second class. Swallows, nighthawks, and some sea-birds are examples of the third class. A few of our birds use their wings to gain an elevation from which to deliver their songs—as the larks, and some of the finches; but the robins and the sparrows and the warblers and the woodpeckers are always going somewhere. The hawks and the buzzards are, comparatively speaking, birds of leisure.

Every bird and beast is a master in the use of its own tools and weapons. We who look on from the outside marvel at their skill. Here is the carpenter bumble-bee hovering and darting about the verge-board of my porch-roof as I write this. It darts swiftly this way and that, and now and then pauses in midair, surrounded by a blur of whirring wings, as often does the hummingbird. How it does it, I do not know. I cannot count or distinguish the separate stroke of its wings. At the same time, the chimney swifts sweep by me like black arrows, on wings apparently as stiff as if made of tin or sheet-iron, now beating the air, now sailing. In some way they suggest winged gimlets. How thin and scimitar-like their wings are! They are certainly masters of their own craft.

In general, birds in flight bring the wings as far below the body as they do above it. Note the crow flapping his way through the air. He is a heavy flyer, but can face a pretty strong wind. His wings probably move through an arc of about ninety degrees. The ph[oe]be flies with a peculiar snappy, jerky flight; its relative the kingbird, with a mincing and hovering flight; it tiptoes through the air. The woodpeckers gallop, alternately closing and spreading their wings. The ordinary flight of the goldfinch is a very marked undulatory flight; a section of it, the rise and the fall, would probably measure fifty feet. The bird goes half that distance or more with wings closed. This is the flight the male indulges in within hearing distance of his brooding mate. During the love season he occasionally gives way to an ecstatic flight. This is a level flight, performed on round, open wings, which beat the air vertically. This flight of ecstasy during the song season is common to many of our birds. I have seen even the song sparrow indulge in it, rising fifty feet or more and delivering its simple song with obvious excitement. The idiotic-looking woodcock, inspired by the grand passion, rises upon whistling wings in the early spring twilight, and floats and circles at an altitude of a hundred feet or more, and in rapid smackering and chippering notes unburdens his soul. The song of ecstasy with our meadowlark is delivered in a level flight and is sharp and hurried, both flight and song differing radically from its everyday performance. One thinks of the bobolink as singing almost habitually on the wing. He is the most rollicking and song-drunk of all our singing birds. His season is brief but hilarious. In his level flight he seems to use only the tips of his wings, and we see them always below the level of his back. Our common birds that have no flight-song, so far as I have observed, are the bluebird, the robin, the ph[oe]be, the social sparrow, the tanager, the grosbeak, the pewee, the wood warblers, and most of the ground warblers.

Over thirty years ago a writer on flying-machines had this to say about the flight of sea-gulls: "Sweeping around in circles, occasionally elevating themselves by a few flaps of the wings, they glide down and up the aerial inclines without apparently any effort whatever. But a close observation will show that at every turn the angle of inclination of the wings is changed to meet the new conditions. There is continual movement with power—by the bird it is done instinctively, by our machine only through mechanism obeying a mind not nearly so well instructed."

The albatross will follow a ship at sea, sailing round and round, in a brisk breeze, on unbending wing, only now and then righting itself with a single flap of its great pinions. It literally rides upon the storm.

IV

BIRD INTIMACIES

When, as sometimes happens, I feel an inclination to seek out new lands in my own country, or in other countries, to see what Nature is doing there, and what guise she wears, something prompts me to pause, and after a while to say to myself: "Look a little closer into the nature right at your own door; do a little intensive observation at home, and see what that yields you. The enticement of the far-away is mostly in your imagination; let your eyes and your imagination play once more on the old familiar birds and objects."

One season in my walks to the woods I was on the lookout for a natural bracket among the tree-branches, to be used in supporting a book-shelf. I did not find it; but one day in a shad-blow tree, within a few feet from the corner of my own house, I found what I was searching for, perfect in every particular—the right angle and the supporting brace, or hypothenuse. It gave me a hint I have not forgotten.

I find that one has only to overcome a little of his obtuseness and indifference and look a little more closely upon the play of wild life about him to realize how much interesting natural history is being enacted every day before his very eyes—in his own garden and dooryard and apple-orchard and vineyard. If one's mind were only alert and sensitive enough to take it all in! Whether one rides or walks or sits under the trees, or loiters about the fields or woods, the play of wild life is going on about him, and, if he happens to be blessed with the seeing eye and the hearing ear, is available for his instruction and entertainment. On every farm in the land a volume of live natural history goes to waste every year because there is no historian to note the happenings.

The drama of wild life goes on more or less behind screens—a screen of leaves or of grass, or of vines, or of tree-trunks, and only the alert and sympathetic eye penetrates it. The keenest of us see only a mere fraction of it. If one saw one tenth of the significant happenings that take place on his few acres of orchard, lawn, and vineyard in the course of the season, or even of a single week, what a harvest he would have! The drama of wild life is played rapidly; the actors are on and off the stage before we fairly know it, and the play shifts to other stages.

I wonder how many of the scores of persons passing along the road between my place and the railway station one early May day became aware that a rare bird incident was being enacted in the trees over their heads. It was the annual sängerfest of the goldfinches—one of the prettiest episodes in the lives of any of our birds, a real musical reunion of the goldfinch tribe, apparently a whole township, many hundreds of them, filling scores of the tree-tops along the road and in the groves with a fine, sibilant chorus which the ear refers vaguely to the surrounding tree-tops, but which the eye fails adequately to account for. It comes from everywhere, but from nowhere in particular. The birds sit singly here and there amid the branches, and it is difficult to identify the singers. It is a minor strain, but multitudinous, and fills all the air. The males are just donning their golden uniforms, as if to celebrate the blooming of the dandelions, which, with the elm-trees, afford them their earliest food-supply. While they are singing they are busy cutting out the green germs of the elm flakes, and going down to the ground and tearing open the closed dandelion-heads that have shut up to ripen their seeds, preparatory to their second and ethereal flowering when they become spheres of fragile silver down.

Whether this annual reunion of the goldfinches should be called a dandelion festival, or a new-coat festival, or whether it is to bring the sexes together preliminary to the mating-season, I am at a loss to decide. It usually lasts a week or more, and continues on wet days as well as on fair. It all has a decidedly festive air, like the fête-days of humans. I know of nothing like it among other birds. It is the manifestation of something different from the flocking instinct; it is the social and holiday instinct, bringing the birds together for a brief season, as if in celebration of some special event or purpose. I have observed it in my vicinity every spring for many years, usually in April or early May, and it is the prettiest and most significant bird episode, involving a whole species, known to me.

The goldfinch has many pretty ways. He is one of our most amiable birds. So far as my knowledge goes, he is not capable of one harsh note. His tones are all either joyous or plaintive. In his spring reunions they are joyous. In the peculiar flight-song in which he indulges in the mating season, beating the air vertically with his round, open wings, his tones are fairly ecstatic. His call to his mate when she is brooding, and when he circles about her in that long, billowy flight, the crests of his airy waves being thirty or forty feet apart, calling, "Perchic-o-pee, perchic-o-pee," as if he were saying, "For love of thee, for love of thee," and she calling back, "Yes, dearie; yes, dearie"—his tones at such times express contentment and reassurance.

When any of his natural enemies appear—a hawk, a cat, a jay—his tones are plaintive and appealing. "Pit-y, pit-y!" he cries in sorrow and not in anger.

When with his mate he leads their brood about the August thistles, the young call in a similar tone. When in July the nesting has begun, the female talks the prettiest "baby talk" to her mate as he feeds her. The nest-building rarely begins till thistledown can be had—so literally are all the ways of this darling bird ways of softness and gentleness. The nest is a thick, soft, warm structure, securely fastened in the fork of a maple or an apple-tree.

None of our familiar birds endear themselves to us more than does the bluebird. The first bluebird in the spring is as welcome as the blue sky itself. The season seems softened and tempered as soon as we hear his note and see his warm breast and azure wing. His gentle manners, his soft, appealing voice, not less than his pleasing hues, seem born of the bright and genial skies. He is the spirit of the April days incarnated in a bird. He has the quality of winsomeness, like the violet and the speedwell among the flowers. Not strictly a songster, yet his every note and call is from out the soul of harmony. The bluebird is evidently an offshoot from the thrush family, and without the thrush's gift of song; still his voice affords us much of the same pleasure.

How readily the bluebirds become our friends and neighbors when we offer them suitable nesting-retreats! Bring them something from nature, something with the bark on—a section of a dry beech or maple limb in which the downy woodpecker has excavated his chamber and passed the winter or reared his brood; fasten it in early spring upon the corner of your porch, or on the trunk of a near-by tree, and see what interesting neighbors you will soon have. One summer I brought home from one of my walks to the woods a section, two or three feet long, of a large yellow birch limb which contained such a cavity as I speak of, and I wired it to one of the posts of the rustic porch at Woodchuck Lodge. The next season a pair of bluebirds reared two broods in it. The incubation of the eggs for the second brood was well under way when I appeared upon the scene in early July. My sudden presence so near their treasures, and my lingering there with books and newspapers, disturbed the birds a good deal. The first afternoon the mother bird did not enter the cavity for hours. I shall always remember the pretty and earnest manner in which the male tried to reassure her and persuade her that the danger was not so imminent as it appeared to be, probably encouraging a confidence in his mate which he did not himself share. The mother bird would alight at the entrance to the chamber, but, with her eye fixed upon the man with the newspaper, feared to enter. The male, perched upon the telegraph wire fifty feet away, would raise his wings and put all the love and assurance in his voice he was capable of, apparently trying to dispel her fears. He would warble and warble, and make those pretty wing gestures over and over, saying so plainly: "It is all right, my dear, the man is harmless—absorbed there in his newspaper. Go in, go in, and keep warm our precious eggs!" How long she hesitated! But as night grew near she grew more and more anxious, and he more and more eloquent. Finally she alighted upon the edge of the overhanging roof and peered down hesitatingly. Her mate applauded and encouraged till finally she made the plunge and entered the hole, but instantly came out again; her heart failed her for a moment; but she soon returned and remained inside. Then her mate flew away toward the orchard, uttering a cheery note which doubtless she understood.

The birds soon became used to my presence and their household matters progressed satisfactorily. Both birds took a hand in feeding the young, which grew rapidly. When they were nearly ready to leave the nest, a cruel fate befell them: I slept upon the porch, and one night I was awakened by the cry of young bluebirds, and the sound of feet like those of a squirrel on the roof over me. Then I heard the cry of a young bird proceed from the butternut-tree across the road opposite the house. I said to myself, "A squirrel or an owl is after my birds." The cry coming so quickly from the butternut-tree made me suspect an owl, and that the bird whose cry I heard was in his talons. I was out of my cot and up to the nest in a moment, but the tragedy was over; the birds were all gone, and the night was silent. In the morning I found that a piece of the brittle birch limb had been torn away, enlarging the entrance to the cavity so that the murderous talons of the owl could reach in and seize the young birds. I had been aroused in time to hear the marauder on the roof with one, and then hear its cry as he carried it to the tree. In the grass in front I found one of the young, unable to fly, but apparently unhurt. I put it back in the nest, but it would not stay. The spell of the nest was broken, and the young bird took to the grass again. The parent birds were on hand, much excited, and, when I tried to return the surviving bird to the nest, the male came at me fiercely, apparently charging the whole catastrophe to me.

We had strong proof the previous season that an owl, probably the screech owl, prowled about the house at night. A statuette of myself in clay which a sculptor was modeling was left out one night on the porch, and in the morning its head was unusually bowed. The prints of a bird's talons upon the top told what had happened. In the bronze reproduction of that statuette the head has more of a droop than the artist at first planned to give it.

The next season the bluebirds occupied the cavity in the birch limb again, but before my arrival in July the owls had again cleaned them out. In so doing they had ripped the cavity open nearly to the bottom. For all that, early the following May bluebirds were occupying the cavity again. It held three eggs when I arrived. I looked over the situation and resolved to try to head off the owl this time, even at the risk of driving the bluebirds away. I took a strip of tin several inches wide and covered the slit with it and wired it fast. Then I obtained a broad strip of dry birch-bark, wrapped it about the limb over the tin, and wired it fast, leaving the entrance to the nest in its original form. I knew the owl could not slit the tin; the birch-bark would hide it and preserve in a measure the natural appearance of the branch. When the bluebirds saw what had happened to their abode, they were a good deal distressed; they could no longer see their eggs through the slit which the owl had made, and they refused to enter the cavity. They hung about all day, uttering despondent notes, approaching the nest at times, but hesitating even to alight upon the roof above it. Occasionally the female would fly away toward the distant woods or hills uttering that plaintive, homesick note which seemed to mean farewell. The male would follow her, calling in a more cheery and encouraging tone. Once the couple were gone three or four hours, and I concluded they had really deserted the place. But just before sundown they were back again, and the female alighted at the entrance to the nest and looked in. The male called to her cheerily; still she would not enter, but joined him on the telephone wire, where the two seemed to hold a little discussion. Presently the mother bird flew to the nest again, then to the roof above it, then back to the nest, and entered it till only her tail showed, then flew back to the wire beside her mate. She was evidently making up her mind that the case was not hopeless. After a little more maneuvering, and amid the happy, reassuring calls of her mate, she entered the nest cavity and remained, and I was as well pleased as was her mate.

No owls disturbed them this time, and the brood of young birds was brought off in due season. In July a second brood of four was successfully reared and sent forth on their career.

The oriole nests in many kinds of trees—oaks, maples, apple-trees, elms—but her favorite is the elm. She chooses the end of one of the long drooping branches where a group of small swaying twigs affords her suitable support. It is the most unlikely place imaginable for any but a pendent nest, woven to half a dozen or more slender, vertical twigs, and swaying freely in the wind. Few nests are so secure, so hidden, and so completely sheltered from the rains by the drooping leaves above and around it. It is rarely discoverable except from directly beneath it. I think a well-built oriole's nest would sustain a weight of eight or ten pounds before it would be torn from its moorings. They are also very partial to the ends of branches that swing low over the highway. One May I saw two female orioles building their nests twenty or twenty-five feet above our State Road, where automobiles and other vehicles passed nearly every minute all the day. An oriole's nest in a remote field far from highways and dwellings is a rare occurrence.

Birds of different species differ as widely in skill in nest-building as they do in song. From the rude platform of dry twigs and other coarse material of the cuckoo, to the pendent, closely woven pouch of the oriole, the difference in the degree of skill displayed is analogous to the difference between the simple lisp of the cedar-bird, or the little tin whistle of the "chippie," and the golden notes of the wood thrush, or the hilarious song of the bobolink.

Real castles in the air are the nests of the orioles; no other nests are better hidden or apparently more safe from the depredations of crows and squirrels. To start the oriole's nest successfully is quite an engineering feat. The birds inspect the branches many times before they make a decision. When they have decided on the site, the mother bird brings her first string or vegetable fiber and attaches it to a twig by winding it around and around many times, leaving one or both ends hanging free. I have nests where these foundation strings are wound around a twig a dozen times. In her blind windings and tuckings and loopings the bird occasionally ties a substantial knot, but it is never the result of a deliberate purpose as some observers contend, but purely a matter of chance. When she uses only wild vegetable fibers, she fastens it to the twig by a hopeless kind of tangle. It is about the craziest kind of knitting imaginable. After the builder has fastened many lines to opposite twigs, their ends hanging free, she proceeds to span the little gulf by weaving them together. She stands with her claws clasped one to each side, and uses her beak industriously, looping up and fastening the loose ends. I have stood in the road under the nest looking straight up till my head swam, trying to make out just how she did it, but all I could see was the bird standing astride the chasm she was trying to bridge, and busy with the hanging strings. Slowly the maze of loose threads takes a sacklike form, the bottom of the nest thickens, till some morning you see the movement of the bird inside it; her beak comes through the sides from within, like a needle or an awl, seizes a loose hair or thread, and jerks it back through the wall and tightens it. It is a regular stitching or quilting process. The course of any particular thread or fiber is as irregular and haphazard as if it were the work of the wind or the waves. There is plan, but no conscious method of procedure. In fact, a bird's nest is a growth. It is not something builded as we build, in which judgment, design, forethought enter; it is the result of the blind groping of instinct which rarely errs, but which does not see the end from the beginning, as reason does. The oriole sometimes overhands the rim of her nest with strings and fibers to make it firm, and to afford a foundation for her to perch upon, but it is like the pathetic work which an untaught blind child might do under similar conditions. The birds use fine, strong strings in their nest-building at their peril. Many a tragedy results from it. I have an oriole's nest sent me from Michigan on the outside of which is a bird's dried foot with a string ingeniously knotted around it. It would be difficult to tie so complicated a knot. The tragedy is easy to read. Another nest sent me from the Mississippi Valley is largely made up of fragments of fish-line with the fish-hooks on them. But there is no sign that the bird came to grief using this dangerous material. Where the lives of the wild creatures impinge upon our lives is always a danger-line to them. They are partakers of our bounty in many ways, but they pay a tax to fate in others.

The orioles in my part of the country always use the same material in the body of their nests—a kind of soft, gray, flaxlike fiber which they apparently get from some species of everlasting flower. Woven together and quilted through with strings and horse-hairs, it makes strong, warm, feltlike walls. In the nest sent me from Michigan the walls are made of something that suggests brown human hair, except that it is too hard and brittle for hair.

Our orchard oriole also makes a pendent nest, but not so deep and pocketlike as that of the Baltimore oriole, and showing no such elaborate use of strings and hairs. It is made entirely of some sort of dried grass, very elaborately woven together.

Bullock's oriole of California weaves its nest entirely of the long, strong threads which it draws out of the palm-leaves. The only one I have seen was suspended from the under side of one of those leaves.

I think the prize nest of the woods, if we except the nest of the hummingbird, is that of the wood pewee. It is as smooth and compact and symmetrical as if turned in a lathe out of some soft, feltlike substance. Of course, the ph[oe]be's artistic masonry under the shelving rocks, covered with moss and lined with feathers, or with the finest dry grass and bark fibers, sheltered from the storms and beyond the reach of four-footed prowlers, is almost ideal. It certainly is a happy thought.

The least flycatcher, the kingbird, the cedar-bird, the goldfinch, the indigo-bird, are all fine nest-builders, each with a style of its own.

About the most insecure nest in our trees is that of the little social sparrow, or "chippie." When the sudden summer storms come, making the tree-tops writhe as if in agony, I think of this frail nest amid the tossing branches. Pass through the grove or orchard after the tempest is over, and you are pretty sure to find several wrecked nests upon the ground. "Chippie" has never learned the art of nest-building in trees. She is a poor architect. She should have kept to the ground or to the low bushes. The true tree nest-builders weave their nests fast to the branches, but "Chippie" does not; she simply arranges her material loosely between them, where the nest is supported, but not secured. She seems pathetically ignorant of the fact that there are such things as wind and storm. Hence her frail structure is more frequently dislodged from the trees than that of any other bird.

Recently, after a day of violent northwest wind, I found a wrecked robin's nest and eggs upon the lawn under a maple—not a frequent spectacle. The robin's firm masonry is usually proof against wind and rain, but in this case the nest was composed almost entirely of dry grass; there was hardly a trace of mud in it, hence it was flexible and yielding, and had no grip of the branches. It was evidently the second nest of the pair this season, and the second nest in summer of any species of bird is frailer and more of a makeshift than the first nest in spring. Comparatively few of our birds attempt to bring off a second brood unless the first attempt has been defeated, but the robin is sure to bring off two, and may bring off three. But the robin is a hustler, probably the most enterprising of all our birds. I recall a mother robin that, in late June, repaired a nest in a climbing rosebush which her first brood had vacated only a week before. A brood of wood thrushes which left their nest about the same time was still being fed by their parents about the place.

The song sparrow, the social sparrow, the ph[oe]be, the bluebird, all build a second nest. The first brood of the bluebird will be looked after by the father in some near-by grove or orchard, while the mother starts a new family in the old nest. If all goes well with them, those two bluebird families will unite and keep together in a loose flock till they migrate in the fall.

So many of our birds nest about our houses and lawns and gardens and along our highways, that at first sight it seems as if they must be drawn there by a sense of greater security for their eggs and young. The robin has become almost a domestic institution. It is rarely that one finds a robin's nest very far from a human habitation. One spring there were four robins' nests on my house and outbuildings—in the vines, on window-sills, or other coigns of vantage. There were at the same time at least fifteen robins' nests on my lot of sixteen acres, and I am quite certain that I have not seen all there were. They were in sheds and apple-trees and spruces and cedars, in the ends of piles of grape-posts, in rosebushes, in the summer-house, and on the porch. We did not expect to get one of the early cherries, and might count ourselves lucky if we got any of the later ones.

A robin has built her nest in my summer-house. She abuses me so when I try to tarry there, after incubation has begun, that I take no comfort and presently withdraw. Until her brood has flown, I am practically a stranger in my open-air rest-house and study.

When the fish crows come egging in the spruces and maples about the house, and I hear the screaming of the robins, I seize my gun and rush out to protect them, but am not always successful, as the mischief is often done before I get within reach; I am not sure but that the robins think—if they think at all—that I am in league with the crows to despoil them. I was not in time to save the eggs of the wood thrush the other morning, when I heard the alarm calls of the birds, but I had the satisfaction of seeing the black marauder go limping over the hill, dropping quills from his wings at nearly every stroke. I am sure he will not come back. The fish crow is one of the most active enemies of our small birds. Of course, he only obeys his instincts in hunting out and devouring their eggs and young, but I fancy I obey something higher than instinct when I protest with powder and shot.

The birds do not mind the approach of the domestic animals, such as the cow, the horse, the sheep, the pig, and they are only a little suspicious of the dog, but the appearance of the cat fills them with sudden alarm. I think that birds that have never before seen a cat join in the hue and cry. What alarms one alarms all within hearing. The orioles are probably the most immune from the depredations of crows and jays and owls of all our birds, and yet they will join in the cry of "Thief, thief!" when a crow appears. (The alarm cry of birds will even arrest the attention of four-footed beasts, and often bring the sportsman's stalking to naught.)

I fancy that Ph[oe]be selects our sheds and bridges and porticoes for her nesting-sites because they are so much more numerous than the overhanging rocks where her forbears built. For the same reason certain of the swallows and the swifts select our barns and chimneys.

If the birds themselves are not afraid to draw near us, why should their instinct lead them to feel that their enemies will be afraid of us? How do they know that a jay or a crow or a red squirrel will be less timid than they are? And why also, if they have such confidence in us, do they raise such a hue and cry when we pass near their nests? The robin in my summer-house knew, if she knew anything, that I had never raised a finger against her. On the contrary, my hoe in the garden had unearthed many a worm and slug for her. Still she sees in me only a possible enemy, and tolerate me with my book or my newspaper near her nest she will not. Another robin has built her nest in a rosebush that has been trained to form an arch over the walk that leads to the kitchen door and only a few yards from it; but whenever we pass and repass she scurries away with loud, angry protests and keeps it up as long as we are in sight, so that we do not feel at all complimented by her settling down so near us. If one's appearance is so alarming, even when he is going to hoe the garden, why did the intolerant bird set up her household gods so near? If I keep away her enemies, why will she not be gracious enough to regard me as her friend? The robin that trusted her brood to the sheltering vines of the woodshed, and lined her nest with the hair of our old gray horse—why should she scream, "Murder!" whenever any of us go to the well a few feet away?

What is the real explanation of the fact that so many of our birds nest so near our dwellings and yet show such unfriendliness when we come near them? Their apparent confidence, on the one hand, contradicts their suspicion on the other. Is it because we have here the workings of a new instinct which has not yet adjusted itself to the workings of the older instinct of solicitude for the safety of the nest and young? My own interpretation is that birds are not drawn near us by any sense of greater security in our vicinity. It is evident from the start that there is an initial fear of us to be overcome. How, then, could the sense of greater safety in our presence arise? Fear and trust do not spring from the same root. How should the robins and thrushes know that their enemies—the jays, the crows, and the like—are more afraid of human beings than they are themselves? Hunted animals pursued by wolves or hounds will at times take refuge in the haunts of men, not because they expect human protection, but because they are desperate, and oblivious to everything save some means of escape. If the hunted deer or fox rushes into an open shed or a barn door, it is because it is desperately hard-pressed, and sees and knows nothing but some object or situation that it may place between itself and its deadly enemy. The great fear obliterates all minor fears.

The key to the behavior of the birds in this respect may be found in the Darwinian theory of natural selection. From the first settlement of the country a few of the common birds, attracted by a more suitable or more abundant food-supply, or other conditions, must inevitably have nested near human dwellings. These birds would thrive better and succeed in bringing off more young than those that nested in more exposed places. Hence, their progeny would soon be in the ascendancy. All animals seem to have associated memory. These birds would naturally return to the scenes and conditions of their youth, and start their nests there. It would not be confidence in men that would draw them; rather would the truth be that the fear of man is inadequate to overcome or annul this home attraction.

The catbird does not come to our vines on the veranda to nest from considerations of safety, but because her line of descent runs through such places. The catbirds and robins and ph[oe]be-birds that were reared far from human habitations doubtless return to such localities to rear their young. The home sense in birds is strong. I have positive proof in a few instances of robins and song sparrows returning successive years to the same neighborhood. It is very certain, I think, that the ph[oe]be-birds that daub our porches with their mud, and in July leave a trail of minute creeping and crawling pests, were not themselves hatched and reared in the pretty, moss-covered structure under the shelving rocks in the woods, or on the hillsides.

How different from the manners of the robins are the manners of a pair of catbirds that have a nest in the honeysuckle against the side of the first-floor sleeping-porch! Nothing seems farther from the nature of the catbird than the hue and cry which the robin at times sets up. The catbird is sly and dislikes publicity. An appealing feline mew is her characteristic note. She never raises her voice like the town-crier, as the robin does, perched in the mean time where all eyes may behold him. The catbird peers and utters her soft protest from her hiding-place in the bushes. This particular pair of catbirds appeared in early May and began slyly to look over the situation in the vines and bushes about the house. All their proceedings were very stealthy; they were like two dark shadows gliding about, avoiding observation—no tree-tops or house-tops for them, but coverts close to the ground. We hoped they would divine safety in the shadow of the cottage, but tried to act as if oblivious of their goings and comings. We saw them now and then stealthily inspecting the tangle of honeysuckle on the east side of the veranda, where a robin last season reared a brood, and the low hedge of barberry-bushes on the south side of the cottage, where a song sparrow had her nest. If they come, which will they take, we wondered. Several times in the early morning I heard the male singing vivaciously and confidently in the thick of the honeysuckle. I guessed that the honeysuckle was the choice of the male, and that his song was a pæan in praise of it, addressed to his mate. But it was nearly a week before his musical argument prevailed and the site was apparently agreed upon.

When the nest-building actually began, the birds were so shy about it that, watch as I might, I failed to catch them in the act. One morning I saw the mother bird in the garden with nesting-material in her beak, but she failed to come to the honeysuckle with it while I watched from a near-by covert. At the same time robins were flying here and there with loaded beaks, and wood thrushes were going through the air trailing long strips of white paper behind them, but the catbird was an emblem of secrecy itself. She, too, brought fragments of white paper to her nest, but no one saw her do it. Like other nest-builders, she apparently put in her big strokes of work in the early morning before the sleepers on the veranda were stirring. A few times my inquisitive eye, cautiously peering over the railing, started her from the vine, but I never saw her enter it with leaf, stick, or straw; yet slowly the nest grew and came into shape, and finally received its finishing touches. So cautiously had the birds proceeded that, were they capable of concepts like us, I should fancy they flattered themselves that we had not the least suspicion of their little secret. The male ceased to sing near the house after the nest was begun. So much time elapsed after the finishing of the nest before the first egg appeared in it that some members of the household feared the birds had deserted it, especially as they were not seen about the premises for several days. But the weather was wet and cool, and the eggs ripened slowly. Then one morning the birds were seen again, and one blue-green egg was discovered in the nest. The next morning another egg was added, and a third egg on the third morning, and a fourth on the fourth morning. In due time incubation began, and thenceforth all went well with our dusky neighbors.

It is an anxious moment for all birds when their young leave the nest. One noontime by the unusual mewing of a parent catbird I felt sure that the critical time had come. Sure enough, there sat one of the young on a twig a few inches above the nest, motionless and hushed. No lusty response to the agitated cry of the mother, as is usually the case with the robin. "No publicity" is the watchword of the young catbirds as well as of the old. An hour or two later another young one was perched on a branch, and before night, when no one was looking, they both disappeared, leaving two motionless birds in the nest. The next morning early, without any signs of alarm or agitation on the part of the old birds, they took the important step. It could hardly have been much of a flight with any of them, as their wing-quills were only partially developed, and their tails were mere stubs. For several days afterward no sign or sound of old or young was seen or heard. They were probably keeping well concealed in the near-by trees or in the vines and currant-bushes in the vineyard. In about a week the whole family appeared briefly in upper branches of the maples near the house. The young were distinguishable from the old only by their shorter tails. A few days later the parent birds were seen moving stealthily through the vines and bushes about the house, or perching on the near-by stakes that supported the wire netting. Are they coming back for a second brood? was the question in our minds.

Soon we began to hear snatches of song from the male, then one morning a regular old-time burst of joy from him in the vine that held the old nest. Then he sang in a syringa-bush near the window on the south side of the cottage, and both birds were soon seen paying frequent visits to the bush. We felt sure another brood was in the air. Whether or not the first brood were now shifting for themselves, we did not know; they never again appeared upon the scene. Finally, on the morning of the Fourth of July, the foundation of a new nest was started in the syringa-bush three feet from the ground, and barely four feet from the window!

We had a view of the proceedings that the first site did not afford us. The old nest appeared to be in perfect condition, but there was evidently no thought with the birds of using it again, as the robins sometimes do, and as bluebirds and cliff swallows always do. A new nest, built of material almost identical with that of the old, and in a more exposed position, was decided upon. It progressed rapidly, and I was delighted to find that the male assisted in the building. Indeed, he was fully as active as the female. Very often they were both in the nest with material at the same moment. They seemed to agree perfectly. At first I got the impression that the male was not quite as decided as the female, and hesitated more, once or twice bringing material that he finally rejected. But he soon warmed up to the work and certainly did his share.

With most species of our birds the nest is entirely built by the female. With the robin, the wood thrush, the ph[oe]be, the oriole, the hummingbird, the pewee, and many others, the male is only an interested spectator of the proceeding. He usually attends his mate in her quest for material, but does not lend a hand, or a bill. I think the cock wren assists in nest-building. I know the male cedar-bird does, and probably the male woodpeckers do also. The male rose-breasted grosbeak assists in incubation, and has been seen to sing upon the nest. It seems fair to infer that he assists in the nest-building also, but I am not certain that he does, and I have heard another observer state that in a nest which he watched the female apparently did it all.

My catbirds both worked overtime one afternoon at least, being on their job as late as seven o'clock. In three days the nest was done, all but touching up the interior. During the construction I laid out pieces of twine and bits of white paper on the bushes and wire netting, also some loose material from the outside of the old nest; all was quickly used. How much labor the birds would have saved themselves had they pulled the old nest to pieces and used the material a second time! I have known the oriole to start a nest, then change her mind, and then detach some of her strings and fibers and carry them to the new site; and I once saw a "chebec" whose eggs had been destroyed pull the old nest to pieces and rebuild it in a tree a hundred feet away.

The male catbird is slightly brighter and fresher-looking than his mate, but we could easily tell her by her often simulating the actions of a young bird when she came with material in her beak; she would alight on a near-by post and slightly spread and quiver her wings in a tender, beseeching kind of way. She would do this also when bringing food to her first brood. When one of the parent birds of any species simulates by voice or manner the young birds, it is always the female; her heart would naturally be more a-quiver with anticipation than that of the male.

On the fifth day the nest was completed and received its first egg. There was considerable delay with the second egg, but it appeared on the second or third day, and the third egg the following day. Then incubation began. In twenty days from the day the nest was begun, the birds were hatched, and in eleven days more they had quietly left the nest.

A friend of mine who has a summer home on one of the trout-streams of the Catskills discovered that the catbird was fond of butter, and she soon had one of the birds coming every day to the dining-room window for its lump of fresh butter, and finally entering the dining-room, perching on the back of the chair, and receiving its morsel of butter from a fork held in the mistress's hand. I think the butter was unsalted. My friend was convinced after three years that the same pair of birds returned to her each year, because each season the male came promptly for his butter.

The furtive and stealthy manners of the catbird contrast strongly with the frank, open manners of the thrushes. Its cousin the brown thrasher goes skulking about in much the same way, flirting from bush to bush like a culprit escaping from justice. But he does love to sing from the April tree-tops where all the world may see and hear, if said world does not come too near. In the South and West the thrasher also nests in the vicinity of houses, but in New York and New England we must look for him in remote, bushy fields. I do not know of any bad traits that go with the thrasher's air of suspicion and secrecy, but I do know of one that goes with the catbird's—I have seen her perch on the rim of another bird's nest and deliberately devour the eggs. But only once. Whether or not she frequently does this, I have no evidence. If she does, she is doubtless so sly about it that she escapes observation.

I welcomed the catbird, though she is not so attractive a neighbor as the wood thrush. She has none of the wood thrush's dignity and grace. She skulks and slinks away like a culprit, while the wood thrush stands up before you or perches upon a limb, and turns his spotted waistcoat toward you in the most open and trusting manner. In fact, few birds have such good manners as the wood thrush, and few have so much the manner of a Paul Pry and eavesdropper as the catbird. The flight of the wood thrush across the lawn is such a picture of grace and harmony, it is music to the eye. The catbird seems saying, "There, there! I told you so, pretty figure, pretty figure you make!" But the courteous thrush (just here I heard the excited calls of robins and the hoarse, angry caw of a crow, and rushed out hatless to see a fish crow fly away from the maple in front of the Study, pursued by a mob of screeching robins. He took refuge in the spruces above the house where the collected robins abused him from surrounding branches. On my appearance he flew away, and the robins dispersed)—but the courteous thrush, I say, invites the good-breeding in you which he himself shows. The thrush never has the air of a culprit, while the catbird seldom has any other air. But I welcome them both. One shall stand for the harmony and repose of bird life, and the other for its restlessness and curiosity. The songs and the manners of birds correspond. The catbird, the brown thrasher, and the mockingbird are all theatrical in their manners—full of gestures of tail and wings, and their songs all imply an audience, while the serene melody of the thrushes is in keeping with the grace and poise of their behavior.

V

A MIDSUMMER IDYL

As I sit here of a midsummer day, in front of the wide-open doors of a big hay-barn, busy with my pen, and look out upon broad meadows where my farmer neighbor is busy with his haymaking, I idly contrast his harvest with mine. I have to admit that he succeeds with his better than I do with mine, though he can make hay only while the sun shines, while I can reap and cure my light fancies nearly as well in the shade as in the sun. Yet his crop is the surer and of more certain value to mankind. But I have this advantage over him—I might make literature out of his haymaking, or might reap his fields after him, and gather a harvest he never dreamed of. What does Emerson say?

One harvest from the field Homeward bring the oxen strong; A second crop thine acres yield, Which I gather in a song.

But the poet, like the farmer, can reap only where he has sown, and if Emerson had not scattered his own heart in the fields his Muse would not reap much there. Song is not one of the instruments with which I gather my harvest, but long ago, as a farm boy, in haymaking, and in driving the cows to and from the pasture, I planted myself there, and whatever comes back to me now from that source is honestly my own. The second crop which I gather is not much more tangible than that which the poet gathers, but the farmer as little suspects its existence as he does that of the poet. I can use what he would gladly reject. His daisies, his buttercups, his orange hawkweed, his yarrow, his meadow-rue, serve my purpose better than they do his. They look better on the printed page than they do in the haymow. Yes, and his timothy and clover have their literary uses, and his new-mown hay may perfume a line in poetry. When one of our poets writes, "wild carrot blooms nod round his quiet bed," he makes better use of this weed than the farmers can.

Certainly a midsummer day in the country, with all its sights and sounds, its singing birds, its skimming swallows, its grazing or ruminating cattle, its drifting cloud-shadows, its grassy perfumes from the meadows and the hillsides, and the farmer with his men and teams busy with the harvest, has material for the literary artist. A good hay day is a good day for the writer and the poet, because it has a certain crispness and pureness; it is positive; it is rich in sunshine; there is a potency in the blue sky which you feel; the high barometer raises your spirits; your thoughts ripen as the hay cures. You can sit in a circle of shade beneath a tree in the fields, or in front of the open hay-barn doors, as I do, and feel the fruition and satisfaction of nature all about you. The brimming meadows seem fairly to purr as the breezes stroke them; the trees rustle their myriad leaves as if in gladness; the many-colored butterflies dance by; the steel blue of the swallows' backs glistens in the sun as they skim the fields; and the mellow boom of the passing bumble-bee but enhances the sense of repose and contentment that pervades the air. The hay cures; the oats and corn deepen their hue; the delicious fragrance of the last wild strawberries is on the breeze; your mental skies are lucid, and life has the midsummer fullness and charm.

As I linger here I note the oft-repeated song of the scarlet tanager in the maple woods that crown a hill above me, and in the loft overhead two broods of swallows are chattering and lining up their light-colored breasts on the rims of their nests, or trying their newly fledged wings while clinging to its sides. The only ominous and unwelcome sound is the call of the cuckoo, which I hear and have heard at nearly all hours for many days, and which surely bodes rain. The countryman who first named this bird the "rain crow" hit the mark. The cuckoo is a devourer of worms and caterpillars, and why he should be interested in rain is hard to see. The tree-toad calls before and during a shower, mainly, I think, because he likes to have his back wet, but why a well-dressed bird like the cuckoo should become a prophet of the rain is a mystery, unless the rain and the shadows are congenial to the gloomy mood in which he usually seems to be. He is the least sprightly and cheery of our birds, and the part of doleful prophet in our bird drama suits him well.

A high barometer is best for the haymakers and it is best for the human spirits. When the smoke goes straight up, one's thoughts are more likely to soar also, and revel in the higher air. The persons who do not like to get up in the morning till the day has been well sunned and aired evidently thrive best on a high barometer. Such days do seem better ventilated, and our lungs take in fuller draughts of air. How curious it is that the air should seem heavy to us when it is light, and light when it is heavy! On those sultry, muggy days when it is an effort to move, and the grasshopper is a burden, the air is light, and we are in the trough of the vast atmospheric wave; while we are on its crest, and are buoyed up both in mind and in body, on the crisp, bright days when the air seems to offer us no resistance. We know that the heavier salt sea-water buoys us up more than the fresh river or pond water, but we do not feel in the same way the lift of the high barometric wave. Even the rough, tough-coated maple-trees in spring are quickly susceptible to these atmospheric changes. The farmer knows that he needs sunshine and crisp air to make maple-sugar as well as to make hay. Let the high blue-domed day with its dry northwest breezes change to a warmer, overcast, humid day from the south, and the flow of sap lessens at once. It would seem as if the trees had nerves on the outside of their dry bark, they respond to the change so quickly. There is no sap without warmth, and yet warmth, without any memory of the frost, stops the flow.

The more the air presses upon us the lighter we feel, and the less it presses upon us the more "logy" we feel. Climb to the top of a mountain ten thousand feet high, and you breathe and move with an effort. The air is light, water boils at a low temperature, and our lungs and muscles seem inadequate to perform their usual functions. There is a kind of pressure that exhilarates us, and an absence of pressure that depresses us.

The pressure of congenial tasks, of worthy work, sets one up, while the idle, the unemployed, has a deficiency of hæmoglobin in his blood. The Lord pity the unemployed man, and pity the man so over-employed that the pressure upon him is like that upon one who works in a tunnel filled with compressed air.

Haying in this pastoral region is the first act in the drama of the harvest, and one likes to see it well staged, as it is to-day—the high blue dome, the rank, dark foliage of the trees, the daisies still white in the sun, the buttercups gilding the pastures and hill-slopes, the clover shedding its perfume, the timothy shaking out its little clouds of pollen as the sickle-bar strikes it, most of the song-birds still vocal, and the tide of summer standing poised at its full. Very soon it will begin to ebb, the stalks of the meadow grasses will become dry and harsh, the clover will fade, the girlish daisies will become coarse and matronly, the birds will sing fitfully or cease altogether, the pastures will turn brown, and the haymakers will find the hay half cured as it stands waiting for them in the meadows.

What a wonderful thing is the grass, so common, so abundant, so various, a green summer snow that softens the outlines of the landscape, that makes a carpet for the foot, that brings a hush to the fields, and that furnishes food to so many and such various creatures! More than the grazing animals live upon the grass. All our cereals—wheat, barley, rye, rice, oats, corn—belong to the great family of the grasses.

Grass is the nap of the fields; it is the undergarment of the hills. It gives us the meadow, a feature in the northern landscape so common that we cease to remark it, but which we miss at once when we enter a tropical or semi-tropical country. In Cuba and Jamaica and Hawaii I saw no meadows and no pastures, no grazing cattle, none of the genial, mellow look which our landscape presents. Harshness, rawness, aridity, are the prevailing notes.

From my barn-door outlook I behold meadows with their boundary line of stone fences that are like lakes and reservoirs of timothy and clover. They are full to the brim, they ripple and rock in the breeze, the green inundation seems about to overwhelm its boundaries, all the surface inequalities of the land are wiped out, the small rocks and stones are hidden, the woodchucks make their roads through it, immersed like dolphins in the sea. What a picture of the plenty and the flowing beneficence of our temperate zone it all presents! Nature in her kinder, gentler moods, dreaming of the tranquil herds and the bursting barns. Surely the vast army of the grass hath its victories, for the most part noiseless, peace-yielding victories that gladden the eye and tranquillize the heart.

The meadow presents a pleasing picture before it is invaded by the haymakers, and a varied and animated one after it is thus invaded; the mowing-machine sending a shudder ahead of it through the grass, the hay-tedder kicking up the green locks like a giant, many-legged grasshopper, the horserake gathering the cured hay into windrows, the white-sleeved men with their forks pitching it into cocks, and, lastly, the huge, soft-cheeked loads of hay, towering above the teams that draw them, brushing against the bar-ways and the lower branches of the trees along their course, slowly winding their way toward the barn. Then the great mows of hay, or the shapely stacks in the fields, and the battle is won. Milk and cream are stored up in well-cured hay, and when the snow of winter fills the meadows as grass fills them in summer, the tranquil cow can still rest and ruminate in contentment.

As the swallows sweep out and in near my head they give out an angry "Sleet, sleet," as if my presence had suddenly become offensive to them. I know what makes the change in their temper. The young are leaving their nests, and at such eventful times the parent birds are always nervous and anxious. When any of our birds launch a family into the world they would rather not have spectators, and you are pretty sure to be abused if you intrude upon the scene. The swallow can put a good deal of sharp emphasis into that "Sleet, sleet," though she is not armed to make any of her threats good. Who knows that all will go well with them when they first make the plunge into space with their untried wings? A careful parent should keep the coast clear.

They have been testing their wings for several days, clinging to the sides of the nest and beating the wings rapidly. And now comes the crucial moment of letting go and attempting actual flight. Several of them have already done it, and I see them resting on the dead limbs of a plum-tree across the road. But more are to follow, and parental anxiety is still rife. I shall be sorry when the spacious hayloft becomes silent. That affectionate "Wit, wit" and that contented and caressing squeaking and chattering give me a sense of winged companionship. The old barn is the abode of friendly and delicate spirits, and the sight of them and the sound of them surely bring a suggestion of poetry and romance to these familiar scenes.

Is not the swallow one of the oldest and dearest of birds? Known to the poets and sages and prophets of all peoples! So infantile, so helpless and awkward upon the earth, so graceful and masterful on the wing, the child and darling of the summer air, reaping its invisible harvest in the fields of space as if it dined on the sunbeams, touching no earthly food, drinking and bathing and mating on the wing, swiftly, tirelessly coursing the long day through, a thought on wings, a lyric in the shape of a bird! Only in the free fields of the summer air could it have got that steel-blue of the wings and that warm tan of the breast. Of course I refer to the barn swallow. The cliff swallow seems less a child of the sky and sun, probably because its sheen and glow are less, and its shape and motions less arrowy. More varied in color, its hues yet lack the intensity, and its flight the swiftness, of those of its brother of the haylofts. The tree swallows and the bank swallows are pleasing, but they are much more local and restricted in their ranges than the barn-frequenters. As a farm boy I did not know them at all, but the barn swallows the summer always brought.

After all, there is but one swallow; the others are particular kinds that we specify. How curious that men should ever have got the notion that this airy, fairy creature, this playmate of the sunbeams, spends the winter hibernating in the mud of ponds and marshes, the bedfellow of newts and frogs and turtles! It is an Old-World legend, born of the blindness and superstition of earlier times. One knows that the rain of the rainbow may be gathered at one's feet in a mud-puddle, but the fleeting spectrum of the bow is not a thing of life. Yet one would as soon think of digging up a rainbow in the mud as a swallow. The swallow follows the sun, and in August is off for the equatorial regions, where it hibernates on the wing, buried in tropical sunshine.

Well, this brilliant day is a good day for the swallows, a good day for the haymakers, and a good day for him who sits before his open barn door and weaves his facts and midsummer fancies into this slight literary fabric.

VI

NEAR VIEWS OF WILD LIFE

The wild life around us is usually so unobtrusive and goes its own way so quietly and furtively that we miss much of it unless we cultivate an interest in it. A person must be interested in it, to paraphrase a line of Wordsworth's, ere to him it will seem worthy of his interest. One thing is linked to another or gives a clue to another. There is no surer way to find birds' nests than to go berrying or fishing. In the blackberry or raspberry bushes you may find the bush sparrow's nest or the indigobird's nest. Once while fishing a trout-stream I missed my fish, and my hook caught on a branch over my head. When I pulled the branch down, there, deftly saddled upon it, was a hummingbird's nest. I unwittingly caught more than I missed. On another occasion I stumbled upon the nest of the water accentor which I had never before found; on still another, upon the nest of the winter wren, a marvel of mossy softness and delicacy hidden under a mossy log.

Along trout-streams with overhanging or shelving ledges the fisherman often sees the nest of the ph[oe]be-bird, which does not cease to please for the hundredth time, because of its fitness and exquisite artistry. On the newly sawn timbers of your porch or woodshed it is far less pleasing, because the bird's art, born of rocky ledges, only serves in the new environment to make its nest conspicuous.

Sitting in my barn-door study I see a vesper sparrow fly up and alight on the telephone wire with nesting-material in her beak. I keep my eye upon her. In a moment she drops down to the grassy and weedy bank of the roadside in front of me and disappears. A few moments later I have her secret—a nest in a little recess in the bank. That straw gave the finishing touch. She kept her place on the nest until she had deposited her first egg on June 24th, probably for her second brood this season. Some young vespers flitting about farther up the road are presumably her first brood. Each day thereafter for four consecutive days she added an egg. Incubation soon began and on the 10th of July the young were out, the little sprawling, skinny things looking, as a city girl said when she first beheld newly-hatched birds in a nest, as if they were mildewed.

These ground-builders among the birds, taking their chances in the great common of the open fields, at the mercy of all their enemies every hour—the hoofs of grazing cattle, prowling skunks, foxes, weasels, coons by night, and crows and hawks by day—what bird-lover does not experience a little thrill when in his walk he comes upon one of their nests? He has found a thing of art among the unkempt and the disorderly; he has found a thing of life and love amid the cold and the insensate. Yet all so artless and natural! Every shred and straw of it serves a purpose; it fairly warms and vivifies the little niche in which it is placed. What a center of solicitude and forethought.

Not many yards below the vesper's nest, on the other side of the road, is a junco's nest. You may know the junco's nest from that of any other ground-builder by its being more elaborate and more perfectly hidden. The nest is tucked far under the mossy and weedy bank, and only a nest-hunter passing along the road, with "eye practiced like a blind man's touch" and with juncos in mind, would have seen it. A little screen of leaves of the hawkweed permits only the rim of one edge of the nest to be seen. Not till I stooped down and reached forth my hand did the mother bird come fluttering out and go down the road with drooping wings and spread tail, the white quills of the latter fairly lighting up the whole performance.

A very shy and artful bird is the junco. I had had brief glimpses of the male many times about the place. The morning I found the nest I had seen one male spitefully pursuing another male along the top of the stone wall opposite, which fact, paralleled in a human case, would afford a hint for detectives to work on. The junco is evidently a very successful bird. The swarms of them that one sees in the late fall and in the early winter going south is good evidence of this. They usually precede the white-throats north in the spring, but a few linger and breed in the high altitude of the Catskills.

When the sun shines hot the sparrow in front of my door makes herself into a sunshade to protect her nestlings. She pants with the heat, and her young pant too; they would probably perish were not the direct rays of the sun kept from them. Another vesper sparrow's nest yonder in the hill pasture, from which we flushed the bird in our walk, might be considered in danger from a large herd of dairy cows, but it is wisely placed in view of such a contingency. It is at the foot of a stalk of Canada thistle about a foot and a half high, and where, for a few square yards, the grazing is very poor. I do not think that the chances are one in fifty that the hoof of a cow will find it. I do not suppose that the problem presented itself to the bird as it does to me, but her instinct was as sure a guide as my reason is to me—or a surer one.

The vesper sparrow was thus happily named by a New England bird-lover, Wilson Flagg, an old-fashioned writer on our birds, fifty or more years ago. I believe the bird was called the grass finch by our earlier writers. It haunts the hilly pastures and roadsides in the Catskill region. It is often called the road-runner, from its habit of running along the road ahead when one is driving or walking—a very different bird, however, from the road-runner of the Western States. The vesper is larger than the song sparrow, of a lighter gray and russet, and does not frequent our gardens and orchards as does the latter. In color it suggests the European skylark; the two lateral white quills in its tail enhance this impression. One season a stray skylark, probably from Long Island or some other place where larks had been liberated, appeared in a broad, low meadow near me, and not finding his own kind paid court to a female vesper sparrow. He pursued her diligently and no doubt pestered her dreadfully. She fled from him precipitately and seemed much embarrassed by the attentions of the distinguished-looking foreigner.

When the young of any species appear, the solicitude and watchfulness of the mother bird are greatly increased. Although my near neighbor the vesper sparrow in front of my door has had proof of my harmless character now for several weeks and, one would think, must know that her precious secret is safe with me, yet, when she comes with food in her beak while I am at my desk ten or eleven yards away, she maneuvers around for a minute or two, flying up to the telephone wire or a few yards up or down the road, and finally approaches the nest with much hesitation and suspicion, lest I see her in the act. When she comes again and again and again, she is filled with the same apprehension.

After a night of heavy but warm rain two of the half-fledged young were lying on the ground in front of the nest, dead. There were no murderous marks upon them, and the secret of the tragedy I could not divine.

What automatons these wild creatures are, apparently so wise on some occasions and so absurd on others! This vesper sparrow in bringing food to her young, going through the same tactics over and over, learns no more than a machine would. But, of course, the bird does not think; hence the folly of her behavior to a being that does. The wisdom of nature, which is so unerring under certain conditions, becomes to us sheer folly under changed conditions.

When the mother bird's suspicion gets the better of her, she often devours the food she has in her beak, so fearful is she of betraying her precious secret. But the next time she comes she may only maneuver briefly before approaching the nest, and then again hesitate and parley with her fears and make false moves and keep her eye on me, as if I had only just appeared upon the scene.

One of the best things a bird-lover can have in front of his house or cabin is a small dead tree with numerous leafless branches. Many kinds of birds love to perch briefly where they can look around them. I would not exchange the old dead plum-tree that stands across the road in front of my lodge for the finest living plum-tree in the world. It bears a perpetual crop of birds. Of course the strictly sylvan birds, such as the warblers, the vireos, the oven-bird, the veery and hermit thrushes, do not come, but many kinds of other birds pause there during the day and seem to enjoy the unobstructed view.

All the field and orchard and grove birds come. In early summer the bobolink perches there, then tiptoes, or tip-wings, away to the meadows below, pouring out his ecstatic song. The rose-breasted grosbeak comes and shows his brilliant front. The purple finch, the goldfinch, the indigo bunting, the bluebird, the kingbird, the ph[oe]be-bird, the great crested flycatcher, the robin, the oriole, the chickadee, the high-hole, the downy woodpecker, the vesper sparrow, the social sparrow, or chippy, pause there in the course of the day, and some of them several times during the day. Occasionally the scarlet tanager lights it up with his vivid color.

But more than all it is the favorite perch of a song sparrow whose mate has a nest not far off. Here he perches and goes through his repertoire of three or four different songs from dawn till nightfall, pausing only long enough now and then to visit his mate or to refresh himself with a little food. He repeats his strain six times a minute, often preening his plumage in the intervals. He sings several hundred times a day and has been doing so for many weeks. The house wren during the breeding-season repeats his song thousands of times a day, while the red-eyed vireo sings continuously from morning till night for several months. How a conscious effort like that would weary our human singers and their hearers! But the birds are quite unconscious, in our sense, of what they are doing.

When we pause to think of it, what a spectacle this singing sparrow presents! A little wild bird sitting on a dead branch and lifting up its voice in song hour after hour, day after day, week after week.

In terms of science we say it is a secondary sexual characteristic, but viewed in the light of the spirit of the whole, what is it except a song of praise and thanksgiving—joy in life, joy in the day, joy in the mate and brood, joy in the paternal and maternal instincts and solicitudes, a voice from the heart of nature that the world is good, thanksgiving for the universal beneficence without which you and I and the little bird would not be here? In foul weather as in fair, the bird sings. The rain and the cold do not silence him.

There are few or no pessimists among the birds. One might think the call of the turtle-dove, which sounds to us like "woe, woe, woe," a wail of despair; but it is not. It really means "love, love, love." The plaint of the wood pewee, pensive and like a human sigh, is far from pessimistic, although in a minor key. The cuckoo comes the nearest to being a pessimist, with his doleful call, and the catbird and the jay, with their peevish and complaining notes, might well be placed in that category, were it not for their songs when the love passion makes optimists even of them. The strain of the hermit thrush which floats down to me from the wooded heights above day after day at all hours, but more as the shades of night are falling—what does this pure, serene, exalted strain mean but that, in Browning's familiar words,

God's in his heaven— All's right with the world!

The bird may sing for his mate and his brood alone, but what puts it into his heart to do that? Certainly it is good to have a mate and a brood!

A new season brings new experiences with the same old familiar birds, or new thoughts about them. This season I have had new impressions of our cuckoos, which are oftener heard than seen. Of the two species, the black-billed and the yellow-billed, the former prevails in the latitude of New England, and the latter farther south. We cannot hail our black-billed as "blithe newcomer," as Wordsworth does his cuckoo. "Doleful newcomer" would be a fitter title. There is nothing cheery or animated in his note, and he is about as much a "wandering voice" as is the European bird. He does not babble of sunshine and of flowers. He is a prophet of the rain, and the country people call him the rain crow. All his notes are harsh and verge on the weird. His nesting-instincts seem to lead him, or rather her, to the thorn-bushes as inevitably as the grass finch's lead her to the grass.

The cuckoo seems such an unpractical and inefficient bird that it is interesting to see it doing things. One of our young poets has a verse in which he sings of

The solemn priestly bumble-bee That marries rose to rose.

He might apply the same or similar adjectives to the cuckoo. Solemn and priestly, or at least monkish, it certainly is. It is a real recluse and suggests the druidical. If it ever frolics or fights, or is gay and cheerful like our other birds, I have yet to witness it.

During the last summer, day after day I saw one of the birds going by my door toward the clump of thorn-trees with a big green worm in its bill. One afternoon I followed it. I found the bird sitting on a branch very still and straight, with the worm still in its beak. I sat down on the tentlike thicket and watched him. Presently he uttered that harsh, guttural note of alarm or displeasure. Then after a minute or two he began to shake and bruise the worm. I waited to see him disclose the nest, but he would not, and finally devoured the worm. Then he hopped or flitted about amid the branches above me, uttering his harsh note every minute or two.

After a half-hour or more I gave it up and parted the curtain of thorny branches which separated the thicket from the meadow and stepped outside. I had moved along only a few paces when I discovered the nest on an outer branch almost in the sunshine. The mother bird was covering her half-grown young. As I put up my hand toward her, she slipped off, withdrew a few feet into the branches, and uttered her guttural calls.

In the nest were four young, one of them nearly ready to leave it, while another barely had its eyes open; the eldest one looked frightened, while the youngest lifted up its head with open mouth for food. The most mature one pointed its bill straight up and sat as still as if petrified. The whole impression one got from the nest and its contents was of something inept and fortuitous. But the cares of a family woke the parents up and they got down to real work in caring for their charge.

The young had a curious, unbirdlike aspect with threadlike yellow stripes, and looked as if they were wet or just out of the shell.

That strain of parasitism in the blood of the cuckoo—how long in the history of its race since it mastered it and became its own nest-builder? But a crude and barbarous nest-builder it certainly is. Its "procreant cradle" is built entirely of the twigs of the thorn-tree, with all their sharp needle-like spines upon them, some of the twigs a foot long, bristling with spines, certainly the most forbidding-looking nest and nursery I ever beheld—a mere platform of twigs about four inches across, carpeted with a little shredded brown fibrous material, looking as if made from the inner bark of some tree, perhaps this very thorn.

In the total absence of the tent caterpillar or apple-tree worm, which is their favorite food, cuckoos seem to succeed in finding a large green worm here in the orchard. In the beech woods they can find a forest worm that is riddling the leaves of the beeches. The robins are there in force and I hope the cuckoos will join them in the destruction of the worms. It is interesting to see the cuckoo fly by several times a day with a big green worm in its beak. Inefficient as it seems, here it is doing things. It is like seeing a monk at the plough-handle. It is a solemn creature; its note is almost funereal.

Our indigo bunting is as artful and secretive about its nesting-habits as any of the sparrows. The male bird seems to know that his brilliant color makes him a shining mark, and he keeps far away from the nest, singing at all hours of the day in a circle around it, the radius of which must be more than fifty yards. In one instance the nest was near the house, almost under the clothes-line, in a low blackberry-bush, partly masked by tall-growing daisies and timothy. I chanced to pass near it, when off went the little brown bird with her sharp, chiding manners. She is a very emphatic creature. It is yea and nay with her every time.

The male seems like a bit of the tropics. He is not a very pleasing singer, but an all-day one and an all-summer one. He is one of our rarer birds. In a neighborhood where you see scores of sparrows and goldfinches you will see only one pair of indigobirds. Their range of food is probably very limited. I have never chanced to see them taking food of any kind.

How crowded with life every square rod of the fields and woods is, if we look closely enough! Beneath my leafy canopy on the edge of the beech woods where I now and then seek refuge from a hot wave, reclining on a cushion of dry leaves or sitting with my back against a cool, smooth exposure of the outcropping place rock, I am in a mood to give myself up to a day of little things. And the little things soon come trooping or looping along.

I see a green measuring-worm taking the dimensions of the rim of my straw hat which lies on the dry leaves beside me. It humps around it in an aimless sort of way, stopping now and then and rearing up on its hind legs and feeling the vacant space around it as a blind man might hunt for a lost trail. I know what it wants: it is on its travels looking for a place in which to go through that wonderful transformation of creeping worm into a winged creature. In its higher stage of being it is a little silvery moth, barely an inch across, and, like other moths, has a brief season of life and love, the female depositing its eggs in some suitable place and then dying or falling a victim to the wood pewee or some other bird. After some minutes of groping and humping about on my hat and on dry twigs and leaves, it is lost to my sight.

A little later a large black worm comes along. It is an inch and a quarter long, and is engaged in the same quest as its lesser brother of the green, transparent coat. Magnify it enough times, say, many thousand times, and what a terrible-looking monster we should have—a traveling arch of contracting and stretching muscular tissue, higher than your head, and measuring off the ground a rod or more at a time, or standing twenty feet or more high, like some dragon of the prime. But now it is a puny insect of which the caroling vireo overhead would quickly dispose.

With a twig I lift it to a maple sapling close by and watch it go looping up the trunk. Evidently it doesn't know just where it wants to go, but it finally strikes a small sugar maple and humps up that. By chance it strikes one of the branches six feet from the ground and goes looping up that. Then, by chance, in its aimless reachings it hits one of three small branches and climbs that a foot or more, and a dry twig, six or eight inches long, is seized and explored. At the end of it the creature tarries a minute or more, reaching out in the empty space, then turns back and hits a smaller twig on this twig about an inch long. This it explores over and over and sounds the depths that surround it, then loops back again to the end of the main twig it has just explored, profiting nothing by experience; then retraces its steps and measures off another small branch, and is finally lost to sight amid the leaves.

Has the course of life up through geologic time been in any way like this? There has been the push of life, the effort to get somewhere, but has there been no more guiding principle than in the case of this worm? The singular thing about the worm is its incessant reachings forth into surrounding space, searching, searching, sounding, sounding, as if to be sure that no chance to make a new connection is missed.

Finally the black worm comes to rest and, clinging by its hind feet, lets itself down and simulates a small dry twig, in which disguise it would deceive the sharpest-eyed enemy. No doubt it passed the night posing as a twig.

Among the sylvan denizens that next came upon the stage were a hummingbird, a little red newt, and a wood frog. The hummer makes short work of everything: with a flash and a hum it is gone. This one seemed to be exploring the dry twigs for nesting-material, either spiders' webs or bits of lichen. For a brief moment it perched on a twig a few yards from me. My ardent wish could not hold it any longer. Truly a fairy bird, appearing and vanishing like a thought, familiar with the heart of all the flowers and taking no food grosser than their nectar, the winged jewel of the poets, the surprise and delight of all beholders—it came like a burnished meteor into my leafy alcove and was gone as quickly.

All sylvan things have a charm and delicacy of their own, all except the woodchuck; wherever he is, he is of the earth earthy. The wood frog is known only to woodsmen and farm boys. He is a real sylvan frog, as pretty as a bird, the color of the dry leaves, slender and elegant in form and quick and furtive in movement. My feet disturbed one in the bed of dry leaves. Slowly I moved my hand toward him and stroked his back with a twig. If you can tickle a frog's back in any way you put a spell upon him. He becomes quite hypnotized. He was instantly responsive to my passes. He began to swell and foreshorten, and when I used my finger instead of the twig, he puffed up very rapidly, rose up more upon his feet, and bowed his head. As I continued the titillation he began to give forth broken, subdued croaks, and I wondered if he were going to break out in song. He did not, but he seemed loath to go his way. How different he looked from the dark-colored frogs which in large numbers make a multitudinous croaking and clucking in the little wild pools in spring! He wakes up from his winter nap very early and is in the pools celebrating his nuptials as soon as the ice is off them, and then in two or three days he takes to the open woods and assumes the assimilative coloring of the dry leaves.

The little orange-colored salamander, a most delicate and highly colored little creature, is as harmless as a baby, and about as slow and undecided in its movements. Its cold body seems to like the warmth of your hand. Yet in color it is as rich an orange as the petal of the cardinal flower is a rich scarlet. It seems more than an outside color; it is a glow, and renders the creature almost transparent, an effect as uniform as the radiance of a precious stone. Its little, innocent-looking, three-toed foot, or three and a half toed—how unreptilian it looks through my pocket glass! A baby's hand is not more so. Its throbbing throat, its close-shut mouth, its jet-black eyes with a glint of gold above them—only a close view of these satisfies one.

Here is another remarkable transformation among the small wild folk. In the spring he is a dark, slimy, rather forbidding lizard in the pools; now he is more beautiful than the jewel-weed in the woods. This is said to be an immature form, which returns to the ponds and matures the next season; but whether it is the male or the female that assumes this bright hue, or both, I do not know. The coat seems to be its midsummer holiday uniform which is laid aside when it goes back to the marshes to hibernate in the fall.

Wild creatures so unafraid are sure to have means of protection that do not at once appear. In the case of the newt it is evidently an acrid or other disagreeable secretion, which would cause any animal to repent that took it in its mouth. It is even less concerned at being caught than is the skunk, or porcupine, or stink-bug.

In my retreat I was unwittingly intruding upon the domain of another sylvan denizen, the chipmunk. One afternoon one suddenly came up from the open field below me with his pockets full of provender of some sort; just what sort I wondered, as there was no grain or seeds or any dry food that it would be safe to store underground for the winter.

Beholding me sitting there within two yards of his den was a great surprise to him. He eyed me a long time—squirrel time—making little, spasmodic movements on the flat stone above his den. At a motion of my arm he darted into his hole with an exultant chip. He was soon out with empty pockets, and he then proceeded to sound his little tocsin of distrust or alarm so that all the sylvan folk might hear. As I made no sign, he soon ceased and went about his affairs.

All this time, behind and above me, concealed by a vase fern, reposed that lovely creature of the twilight, the luna moth, just out of her chrysalis, drying and inflating her wings. I chanced to lift the fern screen, and there was this marvel! Her body was as white and spotless as the snow, and her wings, with their Nile-green hue, as fair and delicate as—well, as only those of a luna moth can be. It is as immaculate as an angel. With a twig I carefully lifted her to the trunk of a maple sapling, where she clung and where I soon left her for the night.

While I was loitering there on the threshold of the woods, observing the small sylvan folk, about a hundred yards above me, near the highway, was a bird's nest of a kind I had not seen for more than a score of years, the nest of the veery, or Wilson's thrush. Some friends were camping there with their touring-car outfit in a fringe of the beech woods, and passed and repassed hourly within a few yards of the nest, and, although they each had sharp eyes and sharp ears, they had neither seen nor heard the birds during the two days they had been there.

While calling upon them I chanced to see the hurried movements of a thrush in the low trees six or seven yards away. The bird had food in its beak, which caused me to keep my eye upon it. It quickly flew down to a small clump of ferns that crowned a small knoll in the open, about ten feet from the border of the woods. As it did so, another thrush flew out of the ferns and disappeared in the woods. Their stealthy movements sent a little thrill through me, and I said, Here is a treasure. I parted the ferny screen, and there on the top of the small knoll was the nest with two half-fledged young.

A mowing-machine in a meadow in front of my door gave an unkind cut to a sparrow that had a nest in the clover near the wall. The mower chanced to see the nest before the sickle-bar had swept over it. It contained four young ones just out of the shell. At my suggestion the mower carefully placed it on the top of a stone wall. The parent birds were not seen, but we naturally reasoned that they would come back and would alight upon the wall to make observations.

But that afternoon and the next morning passed, and we saw no anxious bird parents. The young lifted up their open mouths whenever I looked into the nest and seemed to be more contented than abandoned birds usually are. The next night was unseasonably cold, and I expected to find the nestlings dead in the morning; but they were not, and, strangely enough, for babes in the wood or rather on a stone wall, they seemed to be doing well. Maybe the mother bird is still caring for them, I said to myself, and I ambushed myself across the road opposite to them and watched.

I had not long to wait. The mother sparrow came slyly up and dropped some food into an open mouth and disappeared.

Who does not feel a thrill of pleasure when, in sauntering through the woods, his hat just brushes a vireo's nest? This was my experience one morning. The nest was like a natural growth, hanging there like a fairy basket in the fork of a beech twig, woven of dry, delicate, papery, brown and gray wood products, just high enough to escape prowling ground enemies and low enough to escape sharp-eyed tree enemies. Its safety was in its artless art. It was a part of the shadows and the green-and-brown solitude. The weaver had bent down one of the green leaves and made it a part of the nest; it was like the stroke of a great artist. Then the dabs of white here and there, given by the fragments of spiders' cocoons—all helped to blend it with the flickering light and shade.

I gently bent down the branch and four confident heads with open mouths instantly appeared above the brim. The mother bird meanwhile was flitting about in the branches overhead, peering down upon me and uttering her anxious "quay quay," equivalent, I suppose, to saying: "Get away!" This I soon did.

Most of our bird music, like our wild flowers, is soon quickly over. But the red-eyed vireo sings on into September—not an ecstatic strain, but a quiet, contented warble, like a boy whistling at his work.

VII

WITH ROOSEVELT AT PINE KNOT

It was in May during the last term of his Presidency that Roosevelt asked me to go with him down to Pine Knot, Virginia, to help him name his birds. I stayed with him at the White House the night before we started. I remember that at dinner[1] there was an officer from the British army stationed in India, and the talk naturally turned on Indian affairs. I did not take part in it because I knew nothing about India, but Roosevelt was so conversant with Indian affairs and Indian history that you would think he had just been cramming on it, which I knew very well he had not. But that British officer was put on his mettle to hold his own. In fact, Roosevelt knew more about India and England's relation to it than the officer seemed to know. It was amazing to see the thoroughness of his knowledge about India.

[1] Mr. Burroughs's memory played him false here. The incident he speaks of was at a dinner in the White House, just before starting on the Yellowstone trip, in 1903.
C. B.

The next morning we started off for Virginia, taking an early train.

Pine Knot is about one hundred miles from Washington. I think we left the train at Charlottesville, Virginia, and drove about ten miles to Pine Knot; the house is a big barnlike structure on the edge of the woods, a mile from the nearest farmhouse.

Before we reached there we got out of the wagon and walked, as there were a good many warblers in the trees—the spring migration was on. It was pretty warm; I took off my overcoat and the President insisted on carrying it. We identified several warblers there, among them the black-poll, the black-throated blue, and Wilson's black-cap. He knew them in the trees overhead as quickly as I did.

We reached Pine Knot late in the afternoon, but as he was eager for a walk we started off, he leading, as if walking for a wager. We went through fields and woods and briers and marshy places for a mile or more, when we stopped and mopped our brows and turned homeward without having seen many birds.

Mrs. Roosevelt took him to task, I think, when she saw the heated condition in which we returned, for not long afterwards he came to me and said: "Oom John, that was no way to go after birds; we were in too much of a hurry." I replied, "No, Mr. President, that isn't the way I usually go a-birding." His thirst for the wild and the woods, and his joy at returning to these after his winter in the White House, had evidently urged him on. He added, "We will try a different plan to-morrow."

So on the morrow we took a leisurely drive along the highways. Very soon we heard a wren which was new to me. "That's Bewick's wren," he said. We got out and watched it as it darted in and out of the fence and sang.

I asked him if he knew whether the little gray gnatcatcher was to be seen there. I had not seen or heard it for thirty years. "Yes," he replied, "I saw it the last time I was here, over by a spring run."

We walked over to some plum-trees where there had been a house at one time. No sooner had we reached the spot than he cried, "There it is now!" And sure enough, there it was in full song—a little bird the shape of a tiny catbird, with a very fine musical strain.

As we were walking in a field we saw some birds that were new to me. Roosevelt also was puzzled to know what they were till we went among them and stirred them up, discovering that they were females of the blue grosbeak, with some sparrows which we did not identify.

In the course of that walk he showed me a place where he had seen what he had thought at the time to be a flock of wild pigeons. He described how they flew, the swoop of their movements, and the tree where they alighted. I was skeptical, for it had long been thought that wild pigeons were extinct, but that fact had not impressed itself upon his mind. He said if he had known there could be any doubt about it, he would have observed them more closely. I was sorry that he had not, as it was one of the points on which I wanted indisputable evidence. We talked with the colored coachman about the birds, as he also had seen them. His description agreed with Roosevelt's, and he had seen wild pigeons in his youth; still I had my doubts. Subsequently Roosevelt wrote me that he had come to the conclusion that they had been mistaken about their being pigeons.

One day while there, as we were walking through an old weedy field, I chanced to spy, out of the corner of my eye, a nighthawk sitting on the ground only three or four yards away. I called Roosevelt's attention to it and said, "Now, Mr. President, I think with care you can drop your hat over that bird." So he took off his sombrero and crept up on the bird, and was almost in a position to let his hat drop over it when the bird flew to a near tree, alighting lengthwise on the branch as this bird always does. Roosevelt approached it again cautiously and almost succeeded in putting his hand upon it; the bird flew just in time to save itself from his hand.

One Sunday after church he took me to a field where he had recently seen and heard Lincoln's sparrow. We loitered there, reclining upon the dry grass for an hour or more, waiting for the sparrow, but it did not appear.

During my visit there we named over seventy-five species of birds and fowl, he knowing all of them but two, and I knowing all but two. He taught me Bewick's wren and the prairie warbler, and I taught him the swamp sparrow and one of the rarer warblers; I think it was the pine warbler. If he had found the Lincoln sparrow again, he would have been one ahead of me.

I remember talking politics a little with him while we were waiting for the birds, and, knowing that he was expecting Taft to be his successor, I expressed my doubts as to Taft's being able to fill his shoes.

"Oh, yes, he can," he said confidently; "you don't know him as well as I do."

"Of course not," I admitted; "but my feeling is that, though Taft is an able and amiable man, he is not a born leader."

(I am glad to say that Mr. Taft's recent course in support of the proposed League of Nations has quite brought me around to Roosevelt's estimate of him.)

Pine Knot is a secluded place in the woods. One evening as we sat in the lamplight, he reading Lord Cromer on Egypt, and I a book on the man-eating lions of Tsavo, and Mrs. Roosevelt sitting near with her needlework, suddenly Roosevelt's hand came down on the table with such a bang that it made us both jump, and Mrs. Roosevelt exclaimed in a slightly nettled tone, "Why, my dear, what is the matter?"

He had killed a mosquito with a blow that would almost have demolished an African lion.

It occurred to me later that evening how risky it was for the President of the United States to be so unprotected—without a guard of any kind—in that out-of-the-way place, and I expressed something of this to him, suggesting that some one might "kidnap" him.

"Oh," he answered, slapping his hand on his hip pocket, "I go armed, and they would have to be mighty quick to get the drop on me."

Shortly after that, to stretch my legs a little and listen to the night sounds in the Virginia woods, I went out around the cabin and almost immediately heard some animal run heavily through the woods not far from the house. I thought perhaps it was a neighboring dog, but, on speaking of it to Mrs. Roosevelt, was told that two secret service men came every night at nine o'clock and stood on guard till morning, spending the day at a farmhouse in that vicinity. She did not let the President know of this because it would irritate him.

The only flower we saw there which was new to me was the Indian pink. Roosevelt seemed to know the flowers as well as he did the birds. Pink moccasin-flowers and the bird's-foot violet were common in that locality.

On our return trip, Roosevelt's secretary being on the train, Roosevelt threw himself into the dictation of many letters, the wrens and the warblers already sidetracked for the business of the Administration.

I passed another night at the White House, and in the morning early we went out on the White House grounds to look for birds, our quest seeming to attract the puzzled attention of the passers-by.

"They often stare at me as though they thought me crazy," he said, "when they see me gazing up into the trees."

"Well, now they will think I am your keeper," I said.

"Yes, and I your nurse," laughed Mrs. Roosevelt.

When I left, Roosevelt gave me a list of the birds that we had seen while at Pine Knot and hoped that I would sometime write up the trip; in fact, for years after, whenever we would meet, almost the first thing he would say was, "Have you written up our Pine Knot trip yet, Oom John?" And his disappointment at my failure to do so was always unmistakable.[2]

C. B.
Dear Oom John:
Did you ever get the pamphlet on Concealing Coloration? If not, I will send you another. I do hope that you will include in your coming volume of sketches a little account of the time you visited us at Pine Knot, our little Virginia camp, while I was President. I am very proud of you, Oom John, and I want the fact that you were my guest when I was President, and that you and I looked at birds together, recorded there—and don't forget that I showed you the blue grosbeak and the Bewick's wren, and almost all the other birds I said I would!

Ever yours,
Theodore Roosevelt

A STRENUOUS HOLIDAY

One August a few years ago (1918) I set out with some friends for a two weeks' automobile trip into the land of Dixie—joy-riders with a luxurious outfit calculated to be proof against any form of discomfort.

We were headed for the Great Smoky Mountains in North Carolina. I confess that mountains and men that do not smoke suit me better. Still I can stand both, and I started out with the hope that the great Appalachian range held something new and interesting for me. Yet I knew it was a risky thing for an octogenarian to go a-gypsying, and with younger men. Old blood has lost some of its red corpuscles, and does not warm up easily over the things that moved one so deeply when one was younger. More than that, what did I need of an outing? All the latter half of my life has been an outing, and an "inning" seemed more in order. Then, after fourscore years, the desire for change, for new scenes and new people, is at low ebb. The old and familiar draw more strongly. Yet I was fairly enlisted and bound to see the Old Smokies.
