Twin sister to appreciation is discrimination and as we appreciate the architecture of Colonial America we shall also learn to discriminate between the different local manifestations and attribute each to its proper origins. In this connexion a word of explanation should be offered in answer to a question that some readers, no doubt, have already asked themselves regarding the title chosen for this volume--“Why was it not called Colonial Architecture in America?” Solely because such a title would have been misleading. Indeed, there is no more commonly misapplied term than “Colonial Architecture.” Colonial America had two varieties of architecture, one of which is correctly called Colonial and the other is not. The one is entirely distinct from the other and it is mischievous to confound them. The second variety is Georgian and it is illogical and indefensible to call it anything but Georgian. The Colonial architecture evolved its distinctive forms in America subject to the dictates of local necessity while the Georgian was directly transplanted from England and, although it showed marked tendencies to differentiation in the several parts of the Colonies, preserved its unmistakable likeness in every instance to the parent stock from which it sprang. The Colonial architecture which is really Colonial presents several distinctly different forms of local manifestation, each of them pronouncedly characteristic. One form is to be found in New England, and outside of New England it is not to be met with. Another type, of wholly diverse aspect, is peculiar to the parts of New York State settled at an early period by the Dutch colonists and to the parts of Long Island and northern New Jersey where Dutch influence was paramount. Still another and altogether distinct Colonial type of architecture is to be seen in numerous examples in Pennsylvania, New Jersey and Delaware. A fourth type, with yet other clearly defined peculiarities, may occasionally be discovered in Maryland, Virginia and the Carolinas. The scarcity of examples of true Colonial architecture in the last-named section is explicable by the fact that the southern planter, when his wealth increased, chose to live in more sumptuous manner than his first built dwelling permitted. He therefore built himself a stately Georgian house, better suited to the more elegant style and equipage he now found himself able to maintain. The “fair brick house” in Georgian mode, with porticoes and pillars, often stood upon the site of the earlier house, which was either partially incorporated with it or demolished to make way for it because the first chosen location was the most eligible on the estate and best suited the fancy of the owner.
