DREER'S VEGETABLES UNDER GLASS. 13 
with beveled tops supporting the upright boards are set in 
the walk or alley, in order to utilize every square inch of 
under-glass space in the bed. 
The gardener ‘‘rests’’ his frames in summer by strip- 
ping them of their glass and changing their crops. No idle 
days are allowed them. No weeds are permitted to grow 
in them. They must get along without any summer holi- 
days. Even the alleys are cropped. 
The picture shows how easy it is to work the ‘‘ boxes ”’ 
and alleys by horse power. It is only necessary to remove 
the ends of the ‘‘boxes,’’ and the horse may be driven 
through, as no cross bars are used, as was formerly the 
custom. 
In the spring the horse aids in preparing the ground for 
the open-air crops, and in the autumn in getting ready for 
winter. Ofcourse the horse cannot be used in cultural oper- 
ations while crops are in the frames. 
It will be understood that the words ‘‘frames’’ and 
‘“boxes’’ are synonymous. The Philadelphia market gar- 
dener employs the latter term. The Boston gardener calls 
them ‘‘strings,”’ 
It is not uncommon for gardeners to take care of two or 
three thousand sashes. The Budlong people, near Provi- 
dence, Rhode Island, operate ten thousand sashes. Miles 
of them! And all are protected on the north side by high 
wooden fences. 
A PHILADELPHIA WINTER GARDEN. In the northern 
part of Philadelphia, on Richmond street, John Davis oper- 
ates about two thousand sashes. His ‘‘boxes’’ occupy 
a rectangular space which is wholly surrounded by a high 
board fence, which serves to break the force of the wind. 
His frames are built in the most simple manner ; simply two 
lines of boards set on their edges, one line being twelve 
inches high and the other six inches high. There is a six- 
foot connecting board at each end of the ‘* box,’’ of course.
