By 1763, Great Britain had completely conquered France and Spain, and a treaty of peace was signed at Paris. France and Spain agreed to give up all of North America east of the Mississippi, and England ceded _Cuba to Spain in exchange for Florida, exchanging Florida in 1783 for the Bahama Islands. The former_ was a victory for Spanish diplomacy, since Florida was practically worthless to _Spain_, while Havana, _the capital of Cuba_, was an enormously wealthy city, and the island possessed marvelous fertility and almost boundless resources. France, after her wholesale yielding to England, paid Spain her ally by ceding to her all her possessions west of the Mississippi, including the city of New Orleans. This enormous territory, then known as Louisiana, comprehended everything between the Rocky Mountains and the Mississippi River, from British America to the Gulf of Mexico. In extent it was an empire from which many of the most important States of the Union have been carved. When it is remembered that these changes were the result of a war in which the capture of Quebec was the decisive conflict, it will be admitted that there was ample warrant for pronouncing it one of the great battles of the world. The thirteen original colonies were now "full grown." Their population had increased to 2,000,000 and was fast growing. Their men had proven their bravery and generalship in the French and Indian War. Many of them had developed into fine officers, and all compared favorably with the British regulars. Their loyalty to England was proven by the 30,000 lives that had been given that she might conquer her traditional rival and enemy. The adventurous spirit of the colonists was shown by the fact that many began crossing the Alleghanies into the fertile district beyond, where they were in continual danger from the fierce Indians. James Robertson led a party of emigrants who made the first settlement in Tennessee in 1768, and the famous Daniel Boone and a company of immigrants were the pioneers in Kentucky in 1769. No effort was made to settle the country north of the Ohio until after the Revolution. [Illustration: MEMORIAL HALL, HARVARD COLLEGE.] The intellectual progress of the colonies was remarkable. The first printing press was set up at Cambridge in 1639, and newspapers and books were in general circulation. Harvard College was founded in Massachusetts in 1638; William and Mary, in Virginia, in 1692; Yale, in Connecticut, in 1700; the College of New Jersey (now Princeton University), in 1746; the University of Pennsylvania, in 1749; and King's College (now Columbia), in New York, in 1754. Much attention was given to education, commerce was greatly extended, the oppressive Navigation Act being generally disregarded, and thousands of citizens were in prosperous circumstances.
