[To THE EDITOR OP Tan " SPECTATOR."]
SIR,—In the Spectator of March 15th, p. 332, under Handi- crafts and Reconstruction, you speak of "the abominable practice" of building cavity-walled cottages, and quote Mr. Thackeray Turner as saying that this "means that the house is enclosed in a damp unventilated air jacket." May I ask why it should be unventilated? Surely no builder In his senses would willingly build a cavity wall without ventilation. A few years before the war I built a bungalow with cavity walls precisely as described, but with plenty of ventilation, and find them to be perfectly dry. There is nothing in the wall but brickwork, iron ties, and ventilators—no plaster or paint inside or out. The situation is a very exposed one, where an ordinary nine-inch brick well without good protection outside would be far from dry in rough, wet weather. I em not a builder, but I know when a wall is damp and when it is not, and have had ample demonstration of dryness in this case.—I am, Sir, 8w.,
B. G. RONALDS.
