26 THE GRAPE. 
house may serve as a winter conservatory fo: flowering 
plants, but experience shows, that however late the vines 
may be kept back in the Spring, the buds will burst before 
the weather is suitably mild to turn tho plants out, and 
into the open air; and at this time the vines will require 
a temperature peculiar to themselves which would gene- 
raliy be too damp and close for the plants, many of which 
at the time, will be in a blooming state, requiring more air 
and a cooler atmosphere, than will be suitable for the 
vines ; besides it is almost impossible to keep down insects 
in a house where plants are kept. There is some excuse 
in an early forced grapery, which is so congenial to the 
well being of some natives of the tropics, but as a general 
greenhouse requires heating and the cold grapery does not, 
the expense of two houses is not so great, compared with 
the advantage to be gained; therefore if possible, it is 
much better to have two houses where beth are wanted 
If pecuniary benefit be an object it is also more profitable, 
for the grape if well dealt by, will be honest in return, and 
to erect the house upon stone pillars, or locust, or cedar 
posts, (each of which ought to be directly beneath a rafter,; 
which will allow them free egress to the outside borders. 
There are several ways by which these houses may be 
ventilated, perliaps the most convenient is to admit air at 
the tup, near the bottom, or under the wall plate.
