The repeal of the corn laws gave an immense impetus to British shipping, by opening up new lines of traffic in grain with the ports of the Baltic, the Black Sea, and Egypt; and the extension of steamer communication created another new carrying-business in the transport of coals abroad to innumerable coaling stations. Thus demand goes on creating supply, and supply in turn creating new demand.
From the old fruit and grain sailers of the Mediterranean trade have developed such extensive concerns as the Cunard line (one of whose beginnings was a service of steamers between Liverpool and Havre), which now covers the whole Mediterranean, and extends across the Atlantic to New York and Boston; the Anchor line, which began with a couple of boats running between the Clyde and the Peninsula, and now covers all the Mediterranean and Adriatic, and extends from India to America; the Bibby line, which began with a steamer between Liverpool and Marseilles, and now covers every part of the Mediterranean (Leyland line), and spreads out to Burma and the Straits. These are but a few of many examples of how the great carrying-lines of the world, east and west, have developed from modest enterprises in mid-Europe. And even now the goods traffic between the Mediterranean and the United Kingdom, North Europe and America, is less in the hands of these great lines than in that of the vast fleets of ocean tramps, both sail and steam.
One of the most wonderful developments in the carrying-trade of the world is the concern known as the Messageries Maritimes of France--now probably the largest steamer-owning copartnery in the world. Prior to the Crimean War, there was an enterprise called the Messageries Impériales, which was engaged in the land-carriage of mails through France. In 1851 this company entered into a contract with the French government for the conveyance of mails to Italy, Egypt, Greece, and the Levant; and as years went on, the mail subsidies became so heavy that the enterprise was practically a national one. During the war, the Messageries Company's vessels were in such demand as transports, &c., that the company had to rapidly create a new fleet for mail purposes. With peace came the difficulty of employing the enormously augmented fleet. New lines of mail and cargo boats were therefore successively established between France and the Danube and Black Sea; Bordeaux and Brazil and the River Plate; Marseilles and India and China, &c. In fact, the Messageries Company's ramifications now extend from France to Great Britain, South America, the whole of the Mediterranean, the Levant, the Black Sea, the Red Sea, the Indian Ocean and the China Seas, and the South Pacific.
