(I) The lean-to (fig 5) is the simplest form, often erected against some existing wall, and the best for earl forcing, being warmer on account of the Shelter afforded by the back wall In this house the principal part of the roof is a fixture, ventilas ashes against the back wall, ng on a pi ot so as to swing outwards on the lower side. tion being pro ided for by small lifting and by the upright front sashes being hu The necessary heat is pro ided by four 4-in hot-water 1, pipe; shiclh wdoultd pfsrlsapg Yi ay; c es pace 1 a ai 1* V gg; .~ ' side by side, while the vines are planted in front and g, ' trained upwards under the

Houses of this form are eccllent for general purposes, and they are well adapted both for inuscats, which require a high tem erature, and for late-keeping grapes (3) The:pan-roofad (fig 7) tffe most elegant and ornamental form, is especially adapted for isolated positions, indeed, no other form affords so much roof space for the development of the vines The amount of light admitted being very great, these houses answer w ell for general purposes and for the main crop. The large amount of glass or cooling surface, however, makes it more difficult to keep up a high and regular temperature in them, and from this cause they are not so well adapted for very earl; or ver; late Crops. They are best. ne er the less, when grapes and ornamental plants are grown in the same honse, except, indeed, in very wet and cold distrit ts. where, in consequence of its greater warmth, the lean to is to be prcferrcd FIG. 6.-Hip-Roofed Vinery lighter than the lean to The heating "PQ, (. - V, f S A is ° .T i ~ .s';, T; FIG. 7.-Span-Roofed Vmery. This tx e of house, cheaply constructs cl, is in general use for raising grapes for market. The Peach House is a structure in which the ripening of the fruit is accelerated by the judicious employment of artificial heat. For early forcing, as in vineries, the lean-to form is to be preferred, and the house may have a tolerably sharp pitch A width of 7 or 8 ft, with the glass slope continued down to witliin a foot or two of the ground, and without any upright front sashes, will be suitable for such a house, which may also be conveniently divided into compartments of from 30 to 50 ft in length according to the extent of the building, small houses being preferable to larger ones As a very high temperature is not required, two or three pipes running the whole length of the house will suffice.

Two or three hot-water pipes are placed near the front wall The back wall is u sually planted with dw arf and standard trees alternately, the latter being tem orary, and intended to furnish the upper part of the trellis, while the permanent dwarfs are gradually filling up the trellis from below. In any case the front trellis should stop conveniently short of the top of the sashes if there are trees a ainst the back wal, in order to admit light to them They would also be better carried up nearly parallel to the roof, and at about 1 ft distant from it, supposing there were no trees at the back. A span-roofed house, being lighter than a lean-to, would be so much the better for peach culture, especially for the crop grown Just / ri
