Prior to the World War American deep-sea shipping had shrunk to a woeful degree, and most of America’s imports and exports were carried in foreign ships. The war, however, changed all that, and the United States, in a remarkably short time, had built ships enough to place it second only to Great Britain on the sea. Many of these ships were hurriedly and badly built, it is true, and many ridiculous experiments were tried out, but, despite mistakes, a great merchant fleet was built and put into operation. This, of course, was a war measure, but with the signing of the Armistice America set herself the task of operating this huge fleet. Post-war trade, however, did not call for so many ships as were in operation, and vast fleets of ships were tied up to deteriorate in idleness. Not only America suffered. Great Britain, too, found herself with more ships than cargoes, and all over the world ships were tied up to wait for better times or to fall to pieces in the waiting. This unfortunate condition, however, was not entirely without advantages. It forced economies in operation that resulted in increased efficiency, for ships could only continue to carry cargoes if they did so at low rates, and the shipping lines, therefore, studied every method by which they could reduce their costs of operation. This, of course, brought about many rearrangements. Some formerly successful lines went bankrupt. Many new and inexperienced lines disappeared. Many masters and mates found themselves ashore without work, forced to take employment at whatever tasks they could get. But new lines did make their way, and most of the experienced lines managed to hold on, even going into new fields, as the practical elimination of the German lines gave them some opportunity to do. And following the war, American ships became known in ports where the American flag had not been seen for a generation or more. This probably means that America is on the seas to stay. No longer do internal developments take the attentions of the entire nation. The growth of manufacturing, the lack of wide public domains open to the “homesteader,” the widespread American interests overseas, all point to a permanent merchant marine, not, perhaps, so great as is Great Britain’s, because America is not so vitally dependent on the sea as is Great Britain, but great because America is great, and growing because America is still developing.
