ast of this is a room, or a "potting shed."
Being covered with glass, it is well adapted to growing Mushrooms,
propagating plants, &c., all the room not being needed for potting
purposes. By the side of this room is another boiler room, and on the
south another Hot Grapery, to be used as a "first" house. Then, on the
east is the Cold Grapery, of goodly dimensions. Last of all we have a
Green-house of large size south of the Hot-house. Thus, under one roof,
we have all that is needed on a large place. We do not wish to be
understood as saying that it is always best to put these houses in this
particular shape; but where money is no particular object, and
architectural effect is sought for, this form gives an opportunity in
its broken outlines for considerable display.

DESIGN No. 20.

Green-houses and Graperies are usually erected as separate structures.
While it is desirable that they should be so on extensive places where
much accommodation is required, in grounds of moderate extent many
advantages are gained by having the houses connected. Facility for
heating and management, protection of those houses requiring the most
heat, by those kept cold or at only moderate temperature, and the ease
with which all departments may be visited by the owner, are all obtained
by such an arrangement. In the present instance the Green-house occupies
a position east and west, and is protected on its north and most exposed
quarter by the Grapery. The boiler located as shown on the plan,
supplies heat to all the houses. The Grapery, not being intended as a
forcing or early house, has but one hot water pipe, which will afford
sufficient heat to enable the vines to be started two or three weeks
earlier in the spring, or if not desirable to anticipate their natural
growth, will prevent them receiving sudden checks from frosty nights,
which sometimes happen at the latter end of April and beginning of May,
after the vines have broken their buds. We can prolong the season also,
until about Christmas, in favorable years. Several of the late
ripening, and late keeping varieties of the Grape, are intended to be
grown. Lady Downes, Barbarossa, Frogmore St., Peters and others. These
by the addition of another pipe and proper care in management, could be
kept on the vines in fine condition until February, and perhaps March.
