At Fig. 159w, I have drawn an imaginary roof-garden, constructedwith rafters having a parabolic curve. Hitherto, curved roofs havebeen chiefly made of iron; but I have lately seen a conservatorybuilding, the curved roof bars of which were made of wood, bent bymachinery. It was produced at about half the cost of an iron bending roofs are more graceful than those formed of straight lines,and if wood could be used to such advantage as this experiment indi-cated, the gain even in an aesthetic point of view, would be K5? I now propose to show how such a kind of roof could be 159w, represents a section, copied from an Architectural journal,of the tile and cement roof adopted on the Redcliff Estate, SouthKensington. Here, wooden ribs, two feet apart, span between theparty walls, their ends resting upon stone corbels. On the upper sur-face of these ribs, boarding is laid down, and afterwards, two or threecourses of tiles, bedded in cement, the last course being rendered overwith cement and fine sand. It will be observed from the sketch, thatthe roof is not a flat one; but there is no reason why such a roofcould not be made with an amount of arching just sufficient to throwoff the water.
