Naturally it was from the Mother-Country that the American Colonies derived the models of their earliest architecture. The date at which increased population and prosperity encouraged buildings of a more permanent character, distinguished by their appearance as well as by their immediate utility, is placed at about 1725. From this time the rigour of life in New England, and particularly in Massachusetts, began to be considerably abated. The theocratic form of government, in which the clergy were the arbiters of moral and social conventions, had given way to the active participation of laymen in public affairs. The manners as well as the costumes of society became elegant and the pleasures of life were no longer frowned upon. The change which thus came over social life is reflected in the contrast presented by Copley’s portraits and those of his predecessor, Smibert. A corresponding advance in the amenities of life was represented also in New York and Philadelphia; while, as to the Southern States, which had been colonised by Royalists rather than by Puritans, the tradition of elegant life had always been maintained and the change at this period was only in the increased opportunity of realising it. =English Influences, Modified.=--The edifices which began to be erected comprise churches and meeting-houses, mansions, and a few public halls; the last being of historical rather than architectural interest. The places of worship represent an adaptation of the Wren-Gibbs type, while the domestic designs are based on Queen Anne and Georgian styles. In a few cases the prototype was fairly reproduced; notable examples being =Christ Church, Philadelphia= (1727-35); =Old South Church, Boston=, now used as a museum (1730-82), and =S. Paul’s, New York= (1766). The last named is one of the few instances of stone building at this period; the usual material being either brick imported from England or, far more usually, wood. This affected the use which was made of the drawings of Gibbs, Adam, and others, from which the Colonial church-builders derived their designs. Brick did not permit of carved enrichment. Mouldings were, in consequence, of extreme simplicity and such embellishments as columns, pediments, and cornices were constructed of wood. The character of the design was still further modified in the New England States, since wood was used also for the main structure.
