The predominant local color which distinguishes American Renaissance has been given to it by what has been our great national building commodity, i. e., wood. The Greeks and Romans built of stone when they had the money to pay for it, as does everybody else; otherwise, people in new countries fall back upon a less expensive material. Our less expensive material was wood. Both stone and wood have grain, and have to be used with the same careful regard to it. Whether we build our columns up of stone or wooden sections--latitudinal in the one case, longitudinal in the other--to support a cornice also constructed in sections according to the convenient sizes of commerce for the particular material, makes no difference to the canons of art so long as we are not trying to deceive or to imitate one material with another simply with that end in view. It is extremely doubtful if our American ancestors were ever guilty of premeditated deception. Their material was an honest material; it had to be fashioned in some way, why not after the manner of the Renaissance? In our own day of numerous short-comings in matters architectural it rarely enters the head to deceive upon this point. Notwithstanding the tremendous resources now at command we yet prefer wooden columns to stone ones for dwelling-houses. As national wealth has increased, however, there has been that natural tendency, of course, to carve the Renaissance details of stone, and the white marble porches of Washington square, North (see example, Plate II) may be cited as splendid bits of American Renaissance. But if we go further, and by reason of accumulated affluence erect the entire structure of the new Colonial house in stone--columns, cornices, window and door casings, etc., strange to say we lose an indefinable charm--a certain warmth and personality with which American history has invested wood. Besides, the fashion and style of Renaissance motive and detail is as suitable to wood as it is to stone; and if the first named material is not quite so durable it is much more easily repaired and replaced. In English Renaissance, local conditions commonly restricted the use of wood to the interiors. In American Renaissance, the plenitude of this material enabled the Colonial builders to use it for the outside as well, PLATE III. [Illustration: PICKERING HOUSE, SALEM. Erected A.
