The Wealth of Nations by Part 1 Chapter 9 Page 13

In our North American and West Indian colonies, not only the wages of labour, but the interest of money, and consequently the profits of stock, are higher than in England. In the different colonies both the legal and the market rate of interest run from six to eight per cent. High wages of labour and high profits of stock, however, are things, perhaps, which scarce ever go together, except in the peculiar circumstances of new colonies. A new colony must always for some time be more understocked in proportion to the extent of its territory, and more underpeopled in proportion to the extent of its stock, than the greater part of other countries. They have more land than they have stock to cultivate. What they have, therefore, is applied to the cultivation only of what is most fertile and most favourably situated, the land near the sea shore, and along the banks of navigable rivers.
