ouse is 165 feet long by 14 wide, is a lean-to,
points south, under shelter of a hill. Back wall 12 feet high, 8 feet
stone work; on top of wall 4 feet of wood, in which the back row of
ventilators (2 feet by 20 inches) work, hung on rollers, and all opened
and closed simultaneously by means of a wire representing a front door
pull. Front wall 4 feet high, made by nailing plowed and grooved planks
to locust posts, in which are cut the front ventilators, 4 feet 8 inches
long by 18 inches deep, and covered by a screen of gauze wire with board
shutters to close tight. The roof is made of 16 feet rafters, on which
rests 8 foot sash, immovable; the glass is first quality, 8 by 10. A
single row of supporters on one side of the wall completes the roof. The
interior is divided into three borders: the front border (3 feet 6
inches wide) is raised 9 inches above the walk (which is 2 feet 6 inches
wide); the first back border is 3 feet wide, and raised 16 inches above
the walk; the second back border is raised 1 foot above the front one,
and is 4 feet wide. On this further back border are placed the largest
trees only, having the most head room--the smallest pots standing on the
front. The appearance of the house, when seen by the writer on the 7th
of April, 1860, was truly magnificent, being one dense mass of bloom,
(except some of the early kinds, on which the fruit was already set,)
resembling a green-house of Azaleas in full flower. Peaches, apricots,
nectarines, plums and figs are embraced in the assortment, and are grown
principally in 11-inch pots placed about three feet apart, every leaf
being fully exposed to the sun-light--vines being, of course, entirely
prohibited.

Of the success of this mode of culture in America, no one who has
witnessed Mr. Lovering's house can have the shadow of a doubt. With him
it is no new experiment, having fruited pot trees in his cold graperies
for several years."

_Fig._ 57 is a section of a "lean-to" form of house, showing arrangement
of trees and sunken walk to give sufficient head room.

_Fig._ 58 represents perspective view of a span-roofed house, in which
ventilation is effected at the bottom and very freely at the ends. No
ventilators are placed in the roof as they were not in this case deemed
necessary.
