in the shape of a bridge. A structure of this 
kind may be very simple and cheap, or highly 
elaborate and expensive, according to the 
tastes and means of the proprietor. It is only 
in places which are highly embellished that an 
expensive structure will be in keeping with its 
surroundings, while in 
most all situations a 
rustic bridge is in good 
taste. A rustic bridge 
may be made very 
elaborate in its work¬ 
manship, or it may be ex¬ 
ceedingly simple. Some 
examples of costly struc¬ 
tures of this kind may 
be seen at Central Park. 
We present an engrav¬ 
ing of a very simple one, 
which is not only pleas¬ 
ing in its appearance, 
but its construction is 
such as to render it 
substantial and perma-

all kinds every care should be taken to make 
the abutments secure and the approaches laid 
in a substantial manner. Tiie railing in the

bridge here given is exceedingly plain. It can 
he made much more ornamental by the intro- 
Auetion of rustic panels, and some vines trained 
g it would add greatly to the rustic effect. 
The plans which we give are intended for a 
small greenhouse suitable for an ordinary coun¬ 
try residence where no regu¬ 
lar gardener is kept, and 
where the care of such an 
appendage to the house 
would devolve upon 'the 
family. Such a greenhouse 
can be built separate from 
the dwelling, and a shed at 
tached to the northerly end 
for the purposes of a potting 
shed, the storage of tools, 
etc., but as drawn it is in¬ 
tended to be attached to the 
dwelling, and entered there¬ 
from by means of a door 
from one of the rooms. This 
we consider preferable to 
having it detached, as it is 
accessible and enjoyable in 
all weathers, and if the en¬ 
trance door from the house is glazed it renders 
the room to which it adjoins remarkably cheer¬ 
ful and elegant. We prefer a double-pitched 
roof for such a greenhouse, to a lean-to, or single 
pitch, as it gets the benefit of the early morning 
and latest evening sun, an 
item of much importance in 
growing plants, and escapes 
the intenser heat of the 
noon-day sun (which in 
March and April is very 
great), as the end is per¬ 
pendicular, tiie side of the 
roof being at an angle of 
forty-five degrees. Besides 
these benefits, plants grow 
better in such houses, be¬ 
cause they have more light 
on every side, and conse¬ 
quently are not liable to be¬ 
come so drawn and one¬ 
sided as they are in a lean-to. 
The proper exposure is 
southerly, that is, with tiie 
end facing any of the south¬ 
erly points of tiie compass, 
from W.S.W. to S.E.; if any 
preference can be given in 
locating it, it should lie given to the easterly 
points, as it enables it to receive more of the 
early sun during the shortest days of winter.

and sills, and also tenoned and mortised joints, 
as these are only so many places for the admis¬ 
sion of water and subsequent decay, and also 
involve much outlay for material and labor. 
The sashes measure 6 feet 3 inches long, by 3 
feet one inch wide, and one and a half inch 
thick, made of tiie best quality of white pine.
