are ripening. For grapes the house should be 
25' in width, anything narrower than this giv¬ 
ing too short a cane length to yield a fine crop. 
Another exploded theory is that the founda¬ 
tions should be arched to allow the roots to 
reach the outside border. It has been proved 
that the tight inside border gives better results. 
It also prevents the roots of rank growing trees 
from entering and robbing the soil. Where the 
border is made 4' deep, with a concrete bottom 
and drain in the center, the vine roots have all 
the space they need. Too large a root run is 
not advisable because it prevents the operator 
having absolute control over the conditions. 
Grape Growing 
The roof trellis is the accepted method of 
training grapes. A substantial wire is stretched 
along the roof and sides of the greenhouse 
above the sills and about 15" from the glass. 
The canes are trained on this wire and the side 
shoots trained out horizontally. 
Good soil is very important. A grapery prop¬ 
erly planted will last at least twenty years and 
bear profitably. It is not wise to give the young 
plants the entire border to forage in. A board 
partition can be placed lengthwise of the house, 
giving the plants only about 3' or 4' for the first 
year or two. These boards can be moved as 
the plants require more root space. 
The soil should be good, turfy top soil, some¬ 
thing with a good sod growth. This can be 
used in a proportion of three to one with well-

Figs are comparatively seldom grown in the eastern states, but they are entirely 
susceptible of greenhouse culture. They may be used as potted plants 
The final result. Not 
only are these grapes 
superb in size and 
color, but their 
flavor and palata¬ 
bleness lack nothing

Whether in flower or fruit, the peach tree trained 
to a trellis under glass has a distinct beauty 
A series of perfect screens is formed by the peach trees. These cross trellises are 
superior to the old method of roof training the trees
