During the early 16th century Venice struggled tenaciously to maintain her trade long after Da Gama had rounded the Cape, and the last voyage of the Venetian fleet to England and Flanders did not occur until 1532. The 17th and 18th centuries saw a virtual monopoly of the carriage of the world's trade by the sail ing ship on the ocean. Strictly speaking there are no trade routes on the sea. Once the mariner had learnt to go boldly out of sight of land, he was free of all the ocean, and might descend upon any coast. Practically, however, the greater part of the water surface of the globe is left to-day as in the past to the undisturbed pos session of the albatross and the flying fish, for merchant craft are compelled for economic reasons to keep to the courses which on a balance of considerations are likely to yield the best net results to their owners. In the great sailing days, however, ship-masters took other courses from those followed in the later days of steam, and courses, moreover, which varied in most cases on the outward and homeward voyages. In the Atlantic the trade winds, north east and south-east, determined the sailing tracks, and the Gambia became a place of refreshment on the outward voyage and St Helena on the homeward voyage. Algoa and Delagoa are names which record corresponding facts with reference to the voyages of the Portuguese to and from Goa on the seasonal monsoon winds. Thus the new ocean routes to the Indies came to be punctuated with victualling and watering stations and these stations were the property of the "East India Companies" of the several nations.
At first the Portuguese claimed an exclusive use of the new route which they had discovered to the East, and "stapled" the goods which their ships brought home at Lisbon, and other peoples had to come and buy there. This "pride of the wholesaler" brought its retribution, for the Dutch built up a distributing trade from Lisbon throughout northern Europe, and when Portugal was conquered by Spain, the Dutch rebels against Spain steered past Lisbon and sought their own wares in the East. Amsterdam now became the seat of the depot trade in spices, a term which covered many more articles than in modern parlance. It would exceed the limits of this article to enter into the history of the English and French competition with the Dutch on the trade route to the Indies. Suffice it to say that England ended by defeating all her rivals, in no small measure because her motive was to sell even more than to buy.
the centre and south of Africa offered comparable facilities for early human development. To-day, on an area of some three million square miles in Europe are three hundred million people, and on an area of some five million square miles between Ceylon and Japan are eight hundred million people.
The sailing track from Europe to America was on the north east trade wind to the tropical West Indies, whence shipping turned northward to Virginia and so homeward on the prevalent west winds of the higher latitudes—a great triangle of trade. Only Canada and New England were reached laboriously by tack ing against the west winds. In no trade in the world has the advent of steamships been of greater assistance than in the North Atlantic. Elsewhere on favouring winds a sailing ship would often make nearly as quick a passage as a steamer.
