the border is vaulted; they may be thoroughly protected from frost, but cannot be warmed to any considerable extent, and are consequently less stimulated than the cane and leaves, and do not contribute as largely as the latter require.

Vines which are to be grown from pots are started from cuttings or better, from eyes - which are induced to grow as much as possible the first year, to insure strong plants. When the leaves have all fallen, prune to nine inches in length; keep them through the winter in some dry place well protected from frost. In January or February shift them for the last time into larger pots, not less than a foot in diameter, thoroughly drained, and filled with earth well mixed with rather coarse old turf. Allow as many shoots to grow as can conveniently be accommodated in the place where the pot is to stand; some cultivators retain four or five branches, others but one or two; perhaps one cane is as much as is really judicious. Stop it about five feet long; as often as it starts afresh, stop it, and pinch off the laterals.

In September the plant will lose its leaves, and should be pruned to about 3 feet long for a 12 inch pot, 4 or 5 feet for a 15 inch pot, every additional inch in the diameter of the pot allowing an additional half-foot of cane, although the ultimate length must be regulated by the space allowed during forcing. If the plant is to be forced early, set the pot over the flues or pipes late in December. The culture of potted vines will be described at another time.

DESCRIPTION OF GRAPERY. Having explained the practice to be followed in our grapery, I proceed to describe the building itself. Refer to the ground plans and elevations on next leaf, in connection with the description.

A B C is the grapery; A, retarding-house; B, cold grapery; C, forcing-house; D, shed for boilers, etc.; E, boiler; F, cistern.

The back wall of A is 16 feet high, the front 5 feet high, of which 2 is solid, 2 glass, as in the greenhouse; the building is 12 feet wide. B is 20 feet wide, 6 feet high in front, 14 feet in the middle, 9 feet at the back. C is 12 feet wide, 13 feet high behind, 4 feet in front, of which 2 feet is brick, 2 feet glass. The ar

rangement for ventilation through the wall at the side and top is the same as in the greenhouse and the conservatory. The back wall of C is 2 feet thick, 6 inches of the distance being an air chamber. The back walls of A and B are 1 foot thick; all front walls are 1 foot thick; side walls to glass, 1 foot; above glass, posts, and window sashes, 6 inches in the rough, worked down enough to look well without losing strength. E, the boiler, will be described hereafter. F, the cistern, collects the water from the roofs; there is a well in the shed which can force water into the cistern at need.

The heating is done by means of 4 inch iron pipes, which are carried round the inside of the different buildings, just as in the greenhouse, only that the hot water may be carried into either division of the house without warming the rest any more than would be done by one-half the leading and returning pipes through the grapery, as the water is carried either to the forcing or retardinghouse. The heat derived from this amount of pipe is not enough to much affect the cold grapery; it does not do much more than take the chill off the air at those seasons when this part of the house is intended to be dormant.

The smoke is carried in a brick flue shown by dots, into a flue which runs under the walk in the cold grapery, through to the farther end of the forcing-house, and thence up the chimney. In order to allow the pipes free range about the house, without the extra expense of bends, elbows, etc., the sill of the door is raised so as to be reached either from without or within, by two steps, under which the pipes pass quite out of the way.

On all sides of the forcing-house, grapes are planted. The border is at one end and in front, and takes the roots of the vines in those parts of the house; at the back and the inner end vines are planted in the floor of the grapery, which is a regularly prepared border, and is enriched annually with liquid manure. There is a table on the right of the walk, on which vines in pots are placed for forcing; and over the whole course of the pipes is a narrow table, on which strawberries and some early vegetables may be forced. The vines are brought into the house through cylindrical, oblique holes, 6 inches in diameter in the front and side walls, just between the foundation and the first course of bricks. The
