The Woodlands, the Highlands, and Upsala exemplify for us the third type of Georgian. William Hamilton built the Woodlands about 1770. Anthony Morris finished the Highlands in 1796, and Norton Johnson began Upsala in 1798 and completed it three years later. Across the north front of the Woodlands, at regular intervals, are six Ionic pilasters above whose tops runs an elaborately ornamented entablature with pateræ and flutings, the whole surmounted by a pediment. Before the house is a low and broad paved terrace filling the space between the semi-circular bays that project from the ends of the building. Between the two middle pilasters, a round arched doorway with a fan light opens into the hall. On the south or river front a flight of steps ascends to a lofty white pillared portico from which a door opens directly into the oval shaped ballroom. In another respect the whole exterior aspect of the Woodlands is different from the houses of the second type. Window treatment is always a most important item in determining architectural character and it is just here that a significant change is to be noted. The size of the opening is, in some cases, the same, in others it is larger but, more noticeable still, the muntins are far smaller and we lose the bold, trenchant barring of white that emphasises the aspect of windows of the earlier buildings. The interior is finished with all the delicacy that one might expect judging from the evidences of Adam influence without. One highly significant feature of interior treatment in houses of the third type is the change made in the arrangement of the mantels. We have seen that in houses of the first type, such as Graeme Park and in houses of the second type, such as Whitby Hall or Mount Pleasant, the overmantel panelling and embellishment were accorded much care and elaboration. The chimney breast often extended a considerable distance into the room and the ornamental superstructure above the fireplace reached all the way to the ceiling. Although these ornate overmantels reaching to the ceiling had begun to fall into disfavour in England a little after the middle of the eighteenth century, when houses of the second Georgian type were being erected in the Philadelphia neighbourhood, Colonial conservatism disregarded the newer style and clung to the mode approved by time-honoured precedent. The fireplace with its setting has always held a position of such exalted honour as the centre of family life that the following extract from Clouston’s Treatise on Chippendale is particularly illuminating in this connexion. In speaking of the influence exerted by Sir William Chambers on architecture as well as on furniture, he says:--“When he returned to England in 1755, [from the Continent] he was [Illustration: THE WOODLANDS, NORTH FRONT.] [Illustration: Copyright, J.
