THE £150 COTTAGE.

[To THE EDITOR OF THE "SPECTATOR."] SIR,—As many persons have asked the proportion of gravel or sand to Portland cement in the blocks used by us in the construction of Mr. Strachey's cottages, we beg to say that the proportion is six parts of gravel or sand to one of Portland cement. This we find suitable for the ordinary walls of a two- story cottage. The size and shape of our block is as below.

—We are, Sir, &c., JOAN S. BROWNE AND BROS.

(Builders of Mr. Strachey's Cottages).

.Albury, Guildford.
