A practical treatise on the construction, heating and ventilation of hot-houses; : including conservatories, green-houses, graperies and other kinds of horticultural . ing-houses areerected with the intention of forming an artificial climate forthe culture of tender plants and vegetables in winter and earlyspring. For this purpose artificial heat is employed to keep upan exciting temperature, and, therefore, it is desirable that theyshould be constructed in relation to this end. Until very lately, the form in which forcing-houses were con-structed was that of lean-to, or single-roofed, houses, with shedsor garden-offices on the back of them. When it is not neces-sary that light should be received from all sides of the house,these lean-to houses answer very well, and possess many con-veniences which cannot be obtained with span-roofs. Climbingplants, such as grape-vines, trained beneath the glass, andpeaches, trained in the same manner, derive a sufficiency oflight from the single roof to enable them to bring their fruit toperfection; and it is very doubtful if single roofs will ever beentirely superseded for the purposes of winter forcing. Fig. 3. n. ^^^^i^^i^^^i Fig. 3 is the section of a pit for winter forcing, which we consider well fitted for the several purposes to which these pits4# 40 STRUCTURES ADAPTED TO PARTICULAR PURPOSES. may be applied. The one here represented is what we haveformerly used for the culture of grape vines, French beans, andstrawberries, during winter; and where fermenting manure is tobe had in abundance, it is probably the most economical housefor this kind of forcing. Fig. 4 is the plan of a forcing pit. This house is 80 feet long,in two divisions of 40 feet each. It is chiefly intended for forc-ing vines in pots, and is furnished with a bed, b, which is filledwith fermenting materials for plunging the vines in, and supplyingthem with bottom heat.
