They come under the operation of the rule already noted, that the more dangerous a calling is, the less are its rewards. Three thousand dollars a year is a high income for a pilot sailing out of New York harbor, and even this is decreasing as the ships grow bigger and fewer. Nor can he be at all certain as to what his income will be at any time, for the element of luck enters into it almost as much as into gambling. For weeks he may catch only small ships, or, the worst ill-luck that can befall a pilot, he may get caught on an outbound ship and be carried away for a six weeks' voyage, during which time he can earn nothing. But the pilot, like the typical sailor of whatever grade, is inured to hard luck and accustomed to danger. Such are some of the safeguards which modern science and organization have provided for the sailor in pursuit of his always hazardous calling. Many others of course could be enumerated. The service of the weather bureau, by which warning of impending storms is given to mariners, is already of the highest utility. The new invention of wireless telegraphy, by which a ship at sea may call for aid from ashore, perhaps a thousand miles away, has great possibilities. Modern marine architecture is making steamships almost unsinkable, more quickly responsive to their helms, more seaworthy in every way. Perhaps with the perfection of the submarine boat, ships, instead of being tossed on the boisterous surface of the waves, may go straight to their destination through the placid depths of ocean. But whatever the future may bring, the history of the American sailor will always bear evidence that he did not wait for the perfection of safety devices to wrest from the ocean all that there was of value in the conquest; that no peril daunted him, nor was any sea, however distant, a stranger to his adventurous sail.
