Albert Hale Plumb, William Bradford of Plymouth
“ The Massachusetts Bay Colony, beginning at Salem, had been powerfully augmented at Charlestown and Boston in the summer of 1630, by the arrival of its Governor John Winthrop and others who were soon followed by the New England fleet of no less than ten more vessels carrying about fifteen hundred colonists. The great natural facilities of Boston [92] harbor and its environments encouraged a steady and numerous immigration, so that in 1643, the year of confederation, it is estimated that five times as many were found there as in the Old Colony. ”
