and is quite different in its plan from those before given. It was
designed and erected for J. C. Johnston, Esq., of Scarborough, N. Y.

It is built on the south side of the dwelling, and is entered from the
parlor as well as from the pleasure grounds. _Fig._ 32 is a perspective
view, which gives the reader a good idea of its general appearance,
though we can not help saying that in this case, at least, the picture
does not flatter; the house looks finer on the ground than in the
picture. The circular house on the southeast corner is strictly an
ornamental feature, and a very pretty one.

The interior arrangement is shown in the ground plan, _Fig._ 33. The
house is divided into two compartments, A and B. The last is intended
for growing and propagating plants. The house is heated by hot water
pipes, the boiler being placed in the cellar of the dwelling, which is
entered by the steps, _f_; _e_ is a propagating tank, fitted with
sliding sashes. It is quite large enough to propagate all the plants the
owner will want; _d_, _d_, are beds about a foot deep, with a moderate
bottom heat, for plunging pots in when desired; _w_ is the walk. This
compartment is to be used for bringing plants into bloom, after which
they are to be taken to the show room or conservatory, marked A in the
plan. The arrangement of this compartment is such, that all the plants
in it may be seen from the parlor door or window, the steps leading to
which are marked _b_; _a_, _d_, _d_, are tables; _c_ would make a pretty
little fountain, but it is intended at present to put it in the form of
a rustic basket, and fill it with ornamental plants. The effect can not
be otherwise than good. Climbing plants of various kinds will be trained
up the mullions and rafters of the circular house, and allowed to hang
in festoons from the roof. When the house is filled with flowering and
ornamental-leaved plants, with climbers dependent from the roof, the
effect will be charming.

COLD GRAPERIES FOR CITY LOTS.

In this illustration is given three graperies, designed and constructed
by us for Mr. John H. Sherwood of this city, which are among the first,
if not the first erected in New York, as an elegant, substantial and
attractive addition to three very superb palatial residences on Murray
Hill, near 5th Avenue. These latter are buildings, such as, in styl
