DESCRIPTION AND PROBABLE EXPENSE OF ERECTING A 
METALLIC ROOFED VINERY. 
BY MR. WALDRON. 
I have sent you a sketch of an iron-roofed vinery, (fig. 14,) which - 
I would strongly recommend, both for utility and beauty. I am 
persuaded, one great reason, why metal houses are not found to an¬ 
swer well, is from their not being well constructed ; they are very 
often built by persons totally unacquainted with the advantages or 
disadvantages vegetation derives, from certain modes of construc¬ 
tion, and in very many instances, the gardener has not even an op¬ 
portunity of giving his opinion on the subject. When they are set 
to work, however, and not found to answer, the blame generally falls 
14 
upon the gardener’s shoulders. 
The plan of the house I have sent, 
is to contain 12,000 and upwards 
of cubic feet; and supposing the 
atmosphere, to be as cold as Zero, 
the hot-water apparatus of mine, 
you inserted vol. 1, page 681, will 
give 3,318 cubic inches, at the 
temperature of 180 degrees, which 
will throw a heat into this 30 feet 
house of 58 degrees. If every 
house could thus be readily supplied 
with heat, I think metallic houses 
have had under my care for 
principle, used both for pines, vines, 
satisfied, that if there is a 
would not he in such disrejmte. I 
seven years, houses constructed on this 
and peaches; and I feel quite 
good command of heat, they will be found
