. The book of the garden. Gardening. PINERIES. 341 Esq., of Dublin. It is upon a principle different from most others, and has had its share of criticism, and in some respects has been unfairly dealt with. Fig. 458 is a section of this house, a is the hot-air chamber; b front walk, alongside of which run hot-water pipes ; c back walk, also with hot-water pipes, and brackets over them, on which the melon and cucumber boxes are placed. Along the other side of this path, but in niches cut in the wall, stand tubs or boxes with dwarf Musa plants, the foliage of which canopies over the passage, d roof trellis for vines; e upright supports to which melon and cucumbers are trained ; f external front pathway, to prevent the border from being trodden upon, and to protect the stems of the vines, as will be hereafter noticed. Fig. 459 is a ground-plan of the same house on a smaller scale, and also of the Fig. heated vine border in front, a is pit for pines; b back passage showing the niches for the Musas; c front passage; d vine border; e e air-flues; f hot-water-pipe chamber for heating the border. This house is 60 feet in length, 14^ feet in breadth, and the same in height, from the floor-level to the glass. The roof is slightly curvilinear, and of metal. Bottom heat is produced by introducing hot-water pipes into the chamber usually filled with tan or leaves; the floor of which, being made quite level, is rendered capable of holding a shallow body of wa- ter to produce evaporation, and to coun- teract the drying heat of the hot-water pipes—a judicious arrangement. This chamber is roofed over with Kyanised timber, 3 inches broad and 2 inches deep, leaving spaces of 1 inch between them. Over this is laid about 8 inches of heat- absorbing materials—as brickbats, stones, &c.—with a covering of fresh turf, the green side undermost, and over all 2 feet of half-decayed leaves, into which the pine plants are plunged.
