Another cause was the poor laws by which the people were ruled. Slavery at first was forbidden within its borders, though it was tolerated all about them. Then, in 1747, the trustees yielded to the general demand and admitted slavery. Other rules caused discontent, and many settlers moved away. Population appeared to be at a standstill, and finally the trustees in 1752 surrendered their rights to the crown. More liberal laws followed and the prosperity increased.

It was said of him that he was the handsomest old man in London, and people often stopped on the streets to look at and admire him. He always had a warm regard for the American colonies. Indeed, it was this marked friendship for them which prevented his appointment as commander-in-chief of the British forces during the Revolution. GROWTH OF THE AMERICAN COLONIES. It will thus be seen that, beginning with Virginia, in 1607, the American colonies had grown in a little more than a century and a quarter to thirteen. These were strung along the Atlantic coast from Maine to Florida, and in 1750 their population was about 1,260,000. This was vigorous growth. All the colonists, although born on this side of the Atlantic, considered themselves Englishmen, and were proud of their king, three thousand miles away across the ocean. With such loyal subjects, the English crown had the best opportunity in the world to become the most powerful of all the nations. [Illustration: A COMFORTIER, OR CHAFING-DISH. (New York State Cabinet of Natural History, Albany.)] But Great Britain was not free from misgiving over the rapid growth of her American colonies. Nothing looked more probable than that before many years they would unite in one government of their own and declare their independence of the British crown. Then was the time for the display of wise statesmanship, but unhappily for England and happily for the colonies, such wise statesmanship proved to be lacking on the other side of the water. The colonies displayed great industry. They grew tobacco, rice, indigo, and many other products which were eagerly welcomed by the British merchants, who exported their own manufactures in exchange for them. The inevitable result was that England and the American colonies increased their wealth by this means. Not only that, but the colonies voted ships, men, and money to help the mother country in the wars in which she was often involved.
