the eaves, as will happen without the groove, In exposed 
windy situations additional strength may readily be imparted 
by bolting a few iron braces to the angles of the building at 
any conyenient point, as in fig. H. Pieces of bar iron bent to 
the required angle, flattened, and holes pierced at the ends by 
a blacksmith, answer admirably, and are neat enough in ap- 
pearance when painted, 
The roof support which I have designed for this house, 
though somewhat novel, is, I think, preferable to the ordinary 
method, It consists of central pillars with two arms spring- 
ing through the central tier of the stage at about 9 feet apart. 
The hanging baskets, 1, 1, have a counterpoise at the end of 
a chain or cord running over a wheel, so as to be raised or 
lowered at will for convenience in watering and inspection of

the plants. The effect of two such rows of baskets when well 
filled would be pleasing and materially enhance the appear- 
ance of the interior. To those who prefer the usual plan of 
side pillars fig. I will be useful, as showing a longitudinal sec- 
tional portion of such a pillar, with a slot cast in the top to 
admit a flat iron bar on edge, 1, running along under the roof 
from end to end, and forming a capital support, so slight as to 
make no appreciable shade, and yet very strong ; in size it is 
3 inches by half an inch. The brackets for hanging shelves in 
fig. A, 2, 2, are objectionable as spoiling the appearance of the 
interior, but such shelves are so useful that I have shown where 
they should be placed for the guidance of those who are com- 
pelled to use them, 
The Sides——Here the sashbars are similar to those in the 
roof, the only difference being in the large size, which, as they 
help to support the roof, are 3 inches by 3. They are morticed 
into the wall plate J, which is about 6 inches by 23 or 3, as 
may prove most suitable, and into an eave plate K, 4 inches by 
21. The angle pieces for the corners of the building, L, are 
44 inches by 3, and have rebates, 1, 1, for glazing and for ven- 
tilators to shut into. When side ventilators are introduced, 3, 3, 
fig. A, they consist simply of a frame 23 inches by 13, grooved 
for the glass, with sashbars morticed into the frame, and are 
suspended by hinges to a fixed bar 24 inches by 13, into the 
upper side of which the top side fixed sashbars are morticed. 
Although mention is made of side ventilators, it is by no means
