These seem an absolute necessity, and the wonder is that they have not been fitted before to all ocean liners. Not only are they of use in lighting up the sea a long distance ahead, but as flashlight signals they permit of communication with other ships. As I write, through the window can be seen the flashes from river steamers plying up the Hudson in New York, each with its searchlight, examining the river, lighting up the bank for hundreds of yards ahead, and bringing every object within its reach into prominence. They are regularly used too in the Suez Canal.
I suppose there is no question that the collision would have been avoided had a searchlight been fitted to the Titanic’s masthead: the climatic conditions for its use must have been ideal that night. There are other things besides icebergs: derelicts are reported from time to time, and fishermen lie in the lanes without lights. They would not always be of practical use, however. They would be of no service in heavy rain, in fog, in snow, or in flying spray, and the effect is sometimes to dazzle the eyes of the lookout.
While writing of the lookout, much has been made of the omission to provide the lookout on the Titanic with glasses. The general opinion of officers seems to be that it is better not to provide them, but to rely on good eyesight and wide-awake men. After all, in a question of actual practice, the opinion of officers should be accepted as final, even if it seems to the landsman the better thing to provide glasses.
