It is a standing mystery to me however men can be found who are willing to become the firemen of marine boilers. Use dulls the edge of apprehension, of course, and in time the mind refuses to be impressed by the sense of imminent danger. Whether on the battle-field or in the stokehold this is so; but apart altogether from that, the nature of the work is such that I always wonder what the state of a man's mind can be who is willing to undertake it, or who, having undertaken it, remains in such a business. The engine-room of a large steamship is a terrible place, with its infinite suggestions of incalculable forces exerting themselves in orderly ways under the steady control and guidance of man; but there is a sense of exultation, of high satisfaction, in the realization of their own powers that goes a long way towards compensating the engineers for the dangers they confront, the discomforts they undergo; and where, as in the Mercantile Marine, their high abilities and undaunted courage are fully recognized, their treatment in pay and provisioning and accommodation as good as can be got, they have also something which atones for a great deal of physical suffering. Yes; I can understand a man choosing to become a marine engineer. But a fireman! The very thought of such a life is terrifying. The sailor in his watch on deck at night is seldom called upon to do anything but stand quietly at the helm or on the look-out. If he be a man of any observation, he may hold sweet communion with Nature, may meditate in the sweetest solitude in the world, gazing out upon the ever-beautiful face of the deep. In any case he may smoke, or doze undisturbed by any call to duty, except some shift of wind calling for trimming or setting sail. It is a pleasant mellow time for the sailor, the night watch at sea.
