Fig. G15e. has been proposed to prevent it rising; no doubt the best and most efficacious remedy,but the cost would be gre ter than usually allowed. But the best invention, havingprice also in its favour, is the damp-proof coitrse, formed of brown stoneware, perforatedthroughout its entire width with a half air space, which remains open after the mortarbeds are laid, on each side of the slab. In an executed work, a course of bricks can becut out and the stoneware be inserted. This is one of the many building inventions ofMr. John Taylor, junior. Fig. dloh. shows one for an 18-inch wall; other sizes as wellas angle blocks are provided. Each foot superficial is stated to be equal to the supportof 25 tons or 600 feet of vertical brickwork.
