A new mode of roofing to supersede the use of shingles for that purpose has been invented by John McMurtry, of Lexington, Ky., who has taken measures to secure a patent. The roofing in this instance is made with planks, which are grooved in a peculiar manner, the upper lip being made narrower than the lower to admit the projections of a T-shaped plank called a capping piece, by which the lower plaaks are secured in their place and kept water-tight. In order to drain off any water that might otherwise remain in the crevices ot the roof, and be absorbed by capillary attraction towards the centre joints, the lower planking is made somewhat concave, and a similar shape given to the under side of the top Gapping piece, so that a complete drainage is acquired by means of these gutters. The top of the capping piece should be preferably made oval, that being the best form to prevent the weather from warping it. and by having only one edge of the lower plank nailed down, ample provision is made for the swelling and shrinking of the wood, so as to prevent it from cracking or splitting.
