Most of the colonists who lived along the American seaboard in 1750 were the descendants of immigrants who had come in fully a century before; after the first settlements there had been much less fresh immigration than many latter-day writers have assumed. According to Prescott F. Hall, the population of New England ... at the date of the Revolutionary War ... was produced out of an immigration of about 20,000 persons who arrived before 1640, and we have Franklins authority for the statement that the total population of the coloniesin 1751, then about 1,000,000, had been produced from an original immigration of less than 80,000. Even at that early day, indeed, the colonists had begun to feel that they were distinctly separated, in culture and customs, from the mother-country and there were signs of the rise of a new native aristocracy, entirely distinct from the older aristocracy of the royal governors courts. The enormous difficulties of communication with England helped to foster this sense of separation. The round trip across the ocean occupied the better part of a year, and was hazardous and expensive; a colonist who had made it was a marked manas Hawthorne said, the petit maitre of the colonies. Nor was there any very extensive exchange of ideas, for though most of the books read in the colonies came from England, the great majority of the colonists, down to the middle of the century, seem to have read little save the Bible and biblical commentaries, and in the native literature of the time one seldom comes upon any reference to the English authors who were glorifying the period of the Restoration and the reign of Anne.
