ight be converted into good graperies at an expense that the results
would fully warrant. In case this was successful, it was the owner's
purpose to extend the house along the wall at the left; and it was
therefore deemed best to insert the valley at the angle, to save future
expense in tearing down the end of the house.

_Fig._ 36 is a perspective view of the house, which, in connection with
_Fig._ 38 will give the reader a good idea of the general arrangement.
_Fig._ 37 is a plan.

DESIGN No. 14.

Our next illustration is a hot grapery. It is forty-one feet long and
twenty feet wide. _Fig._ 39 is a perspective view. It is covered with a
low, continuous, curvilinear roof, and is without side lights. The
omission of side lights materially lessens the cost of the house, and
secures additional warmth. In some cases, side lights serve no other
purpose than architectural effect. Graperies, propagating houses, and
plant houses generally may very well be constructed without them; some
of these houses, indeed, are very much better without them.

In the present instance, to prevent what is called a "squatty"
appearance, and also to give additional headway, the side walls were
carried up some twenty inches above the ground line. The house is thus
made to assume a handsome appearance. Air is introduced into the house
at the sides, through underground wooden air chambers opening on the
inside near the walk. Instead of these wooden air chambers, we now use
six inch glazed pipes, as being more convenient and durable. It is an
effective and excellent mode of introducing fresh air, without letting
it directly on the plants. Ventilation is effected by the sash over the
end doors, and also by ventilators placed along the ridge board.

[Illustration: FIG. 40.--_Ground Plan._]

_Fig._ 40 is the ground plan. At the north end a small room is
partitioned off for a boiler pit. On one side is a chest of drawers for
seeds, &c., and on the other some shelving. In connection with the
boiler pit is a coal bin, not, however, of very large capacity. The
house is heated by two four-inch pipes, the design being not to work the
house very early. The border is entirely inside the house, and is
composed principally of sod, muck, and gravel, with the addition of some
old manure and bone shavings. The vines have done well, annually
ripening a fine crop of fruit, and
