The hardships endured by the followers of Endicott and Winthrop prevented many from coming during 1631 and 1632, but in 1633 a new wave of migration set in. Laud became arch-bishop in that year and began a rigorous enforcement of the laws against nonconformists. Many ministers with their congregations in consequence migrated. By the end of 1634 there were nearly four thousand settlers in Massachusetts. The migration continued until the outbreak of war in 1642, by which time the population had increased to about sixteen thousand. The form of government.--The charter vested the government in the governor, deputy governor, assistants, and freemen of the company but not more than twelve of the colonists were legally eligible to membership in the general court. Before disembarking this little group decided that each of the assistants should exercise the same powers as an English justice of the peace. The colony was to be governed by the common law of England, which was to be supplemented by biblical law. At the first general court, held at Boston, October 19, 1630, one hundred and nine men applied for admission as freemen of the corporation. This Winthrop and his associates hesitated to grant, but finally they agreed to admit them, allowing them to elect assistants, but not to hold office. It was also provided that in future no person should be admitted as a freeman unless a member of some church within the colony. Though Winthrop and his followers at first claimed to be members of the Church of England, the necessities of the frontier soon asserted themselves, and each community became a political, economic, and a religious unit. The New England towns.--The New England towns were based upon the idea of group settlement and wherever New Englanders migrated the local organization was reproduced. As Professor Osgood says, "The settlement of a town normally began with the laying out of a village plot and the assignment of home lots. This to an extent determined the location of highways, of the village common, and of some of the outlying fields. On or near the common the church was built, and in not a few cases the site that was chosen for this building went far toward determining the entire lay-out of the town. The idea of a home lot was a plot of ground for a dwelling-house and outbuildings, for a dooryard and garden, and usually also an enclosure for feeding cattle and raising corn."
