America, therefore, is a new market for the produce of its own silver mines, of which the demand must increase much more rapidly than that of the most thriving country in Europe.

Since that time, the direct trade between America and the East Indies, which is carried on by means of the Acapulco ships, has been continually augmenting, and the indirect intercourse by the way of Europe has been augmenting in a still greater proportion. During the sixteenth century, the Portuguese were the only European nation who carried on any regular trade to the East Indies.
