40 THE FORCING GARDEN. 
each giving annually two ounces of ripe fruit in May, 
at 6d. per ounce = 6/.; twenty pot Plums, each giving, 
from the second year onwards, three dozen fruit or 
more, at 3s. per dozen = say 111.; total amount 29/. 
from this house, which cannot be considered an over- 
estimate. 
It appears then that within two years from the 
planting and building of the house the nett cost of it 
can be realised from its produce, and instead of the 
profits being less, they will be decidedly more every 
year afterwards. 
Such a house can be most advantageously used for 
late Grapes, which would in the course of two years, or 
at most the third season, produce a remunerative erop

things. 
THE PEACH AND GRAPE HOUSE COMBINED. 
I am convinced that the same form of house, with 
a 12-inch high front wall of brick and a row of the 
sliding shutters such as I have recommended for the 
early forcing house, can be used for a medium crop of 
Grapes and early Peaches, by a small heating apparatus 
and a set of 3-inch pipes running once through the 
front of the house, 7.e. one flow-and-return pipe lying 
on the floor. This apparatus would cost about 101., 
including the fixing, and the advantages of it would be 
very great, for the Peaches would be much earlier, 
and of course of more value. And although the 
vines could not be allowed to cover the roof, nor be 
closer than five feet apart, with only one fruiting rod 
allowed to each vine, yet the crops would be nearly as
