The Portuguese were able to keep their secrets of the Indian trade for nearly a hundred years, but when it was opened to the English in the early I 7th century, first to the islands and then to the mainland, this route was rapidly developed with a very neces sary victualling station at the Cape of Good Hope. It was after wards continued to China and when the East India Company lost its Indian monopoly in 1814 an alternative was found and it sent many of its ships to Australia with settlers and their stores, then on to China in ballast to load tea for Great Britain.
This tea trade attracted the attention of the American ship owners who, employing very much faster ships than the East Indiamen, worked up a big trade from the United States to China by way of the Cape with general cargo, collecting for the Ameri can and European markets. Their ships entered the British trade from China on the repeal of the Navigation Act, and for a time obtained the cream of the business but almost immediately after wards the discovery of gold in California gave them such oppor tunity on a route that was protected from foreign competition that the Oriental trade was speedily abandoned.
This superior speed was characteristic of American ships. In colonial days their shipping was very severely handicapped by leg islation, but as soon as the United States attained full independ ence they established a lucrative trade along a regular lane from the New England States to the West Indian islands, particularly with the Spanish possessions from which they were debarred. It was to avoid the Spanish warships that the American shipbuilders first turned their attention to speed, and it had a very consider able influence on their trading operations.
The direct route across the Atlantic from Britain to the United States was comparatively neglected until the end of the Napole onic Wars, when the first of the fast sailing vessels which were to become famous as the Western Ocean Packets were started by enterprising Americans and soon included some of the finest ships afloat. Even when regular steamers were running the sailing packets maintained a large measure of their position, particularly in the emigrant traffic. The short distance and the big volume of passenger trade on the North Atlantic permitted fast and luxuri ous tonnage then just as it does to-day.
In the earlier days of Atlantic steam navigation the coal diffi culty necessitated a call at Halifax, which was abandoned when more economical machinery was evolved. Although the direct service is more than ever important, the post-war tendency is to revive such intermediate calls with the less expensive tonnage, while the biggest ships tap the Continental as well as the British trade by making use of the various Channel ports instead of the Western.
This waterway changed all the principal trade lanes to the East. It was not suitable for sailing vessels but favoured the steamship in every respect, so that sailing ship freights fell and it became necessary to build tonnage for large capacity rather than for small ' cargoes at high charges. This sounded the death knell of the clipper. Within comparatively few years the sailing ship as a first class passenger carrier was doomed, although it still had good chances of profit from emigrants and special passengers.
