Journal of horticulture, cottage gardener and country gentlemen . with slates, which are laid without mortar on the divisionand side walls of the pit. Where there is a rather largehole between the slates advantage is taken to place an ordi-nary three-inch drain-pipe with one end over it, or a stillbetter plan is to place these drain-tiles over holes made bytaking the corner off a slate where it rests on the division-waU, and 2 feet apart. A few inches of rubble placed onthe slates, and a sod grass side downwards upon it, wUl pre-vent soU getting down to openings between the slates ; andwhUst allowing the superfluous water of the soil to passaway, will also prevent the steam from the tank rising toomuch through the rubble into the soO, and making it souror sodden, at the same time the advantages of a moistbottom heat are secured. The di-ain-pipes standing on endpass through the soil into the above space, b, b, and through front. The ground plan. A, shows the circulation of thewater, which enters the tank at a, and makes its exit forthe J^ Sift m Fig. 10. Fig. 10 is a lean-to house about 12 feet wide inside. Thepipes for bottom heat are in a tank, a, a, which is aboutthree parts full of water. The tank is covered with flags orslates, but so placed that an opening 2 inches wide is leftbetween them and the walls on which they rest. Thisallows the steam to rise ; and openings being left, or a pieceof li-inch pipe let through the walls of the pits, one end com-municating with the tank and the other with the house, theatmosphere can be made moist, and when not wanted thepipe may be covered with a cap at 6, b, b. A moist heat andan increased temperature is therefore obtained. The houseis ventilated at top, c, and in front by means of boardshung in the centre, and which can be opened much or littleat pleasure. The air entering there is warmed by the hot-water pipes before it reaches the plants, e, e. Are spacesfor EoO over the tanks. There are two pits and
