It is quite possible to preserve random shapes and rock faces in stonework that is structurally good, yet still fail in a measure to please the eye and satisfy the artistic sense. A house built of stones which, although irregular and of variable size, are generally cubical in shape and set with obvious painstaking to simulate a casual yet remarkably systematic arrangement, never fails to be clumsy and patchy. A case in point is Waynesborough in Easttown Township, Chester County, erected in 1724 by Captain Isaac Wayne. Greame Park, erected in Horsham Township, Montgomery County, by Sir William Keith five years after he was appointed governor of Penn's Colony in 1717, instances another unsuccessful use of stonework and effectively explodes the pet notion of the indiscriminate that everything which is old is therefore good. The promiscuous use of rough, long, quarried stones, square blocks and narrow strips on end results in an utterly irrational effect, a confusing medley of short lines. Going to the other extreme, the use of stones so small and irregular as to suggest a "crazy-quilt" mosaic rather than structural stonework is equally displeasing. This scheme unquestionably lends texture to the wall, but it attracts too much attention to itself to the detriment of such architectural features as doors, windows and other wood trim intended to provide suitable embellishment as well as to fulfill the practical requirements of daily use. Inasmuch as rubble used in this manner becomes merely an aggregate in a concrete wall, the consistent thing to do is to consider it as such and give the wall an outside finish or veneer of rough plaster. This fact was recognized and often acted upon by the early Philadelphia builders wherever the stone readily available did not make an attractive wall. A few of the best examples extant serve to indicate that houses of this sort have all the charm of the modern stucco structure built over hollow tile. Perhaps the most picturesque of the old houses of this type is Wyck at Germantown Avenue and Walnut Lane, Germantown, a long, rambling structure of rubble masonry with an outside veneer of rough white plaster standing end to the street. Although Colonial in detail and partaking to a degree of the general character of its neighbors, the ensemble presents a rare blending of European influences with American construction. Vine-clad trellises on the entrance front, a long arbor on the garden front, box-bordered flower beds and a profusion of shade trees and shrubs all help to compose a picture of rare charm in which leading American architects have often found inspiration for modern work.
