17 In New England, some historians of the Puritans understood this process as a great declension. But this captures only one part of a complex transformation, which included strong continuities and positive developments; the best accounts include Richard L. Bushman, From Puritan to Yankee: Character and the Social Order in Connecticut, 1690-1765 (Cambridge, 1967); Robert G. Pope, The Half-Way Covenant (Princeton, 1969). A large literature has also been written on Pennsylvania, including Frederick Tolles, Meeting House and Counting House (Chapel Hill, 1948); and Gary Nash, Quakers and Politics: Pennsylvania, 1681-1726 (Princeton, 1968); Alan Tully, William Perm’s Legacy: Political and Social Structure in Provincial Pennsylvania, 1726-1755 (Baltimore, 1977); on Virginia, Rhys Isaac, The Transformation of Virginia, 1740-1790 (Chapel, Hill, 1982), deals with a different subject. The transformation from Royalists to Whigs in the Chesapeake, and from backsettler to frontiersman in the southern highlands, still await their historians.
