The red tiles, which were used for the most part, are certainly the most agreeable to the artistic eye, for their seemingly haphazard setting, due in part to the builder and in part to nature, affords that pleasure which always arises from an unstudied irregularity of line. Roof tiles were made thicker and less carefully in the old days, and our artist's truth in delineation may be detected in almost any drawing by examining where the weight has swagged away the tiles between the main roof beams. Unlike chimneys erected by our cottage builders of to-day, which appear to issue out of a single mould, those of the untutored architects of the past present every variety of treatment and appearance. The old solidly built chimney seen in many of Mrs. Allingham's cottages (Chiddingfold, Plate 44) is worthy of note as a type of many sturdy fellows which have resisted the ravages of time, and have stood for centuries almost without need of repair. In old days the chimney was regarded not only as a special feature but as an ornament, and not as a necessary but ugly excrescence. Although probably it only served for one room in the house, that service was an important one, and so materials were liberally used in its construction. In Kent and Sussex many of the chimneys are of brick, although the house and the base of the chimney-stack are of stone. This arose from the stone not lending itself to thin slabs, and consequently being altogether too cumbrous and bulky. The windows in the old cottages were naturally small when glass was a luxury, and became fewer in number when a tax upon light was one of the means for carrying on the country's wars. They were usually filled with the smallest panes, fitted into lead lattice, so that breakages might be reduced to the smallest area. Not much of this remains, but a specimen of it is to be seen in the Old Buckinghamshire House (Plate 52). One of the few alterations that Mrs. Allingham allows herself is the substitution of these diamond lattices throughout a house where she finds a single example in any of the lights, or if, as she has on more than one occasion found, that they have been replaced by others, and are themselves stacked up as rubbish. She has in her studio some that have been served in this way, and which have now become useful models.
