THE FRUIT GROWERS GUIDE. 



The structure may be 7 feet 6 inches wide, in which trees can be trained to the 

 wall. The front trellis should not be more than 6 feet high for a structure 7 feet 6 

 inches wide, the trellis 9 to 1 2 inches from the glass. Walls are best wired, the wires 

 not more than 6 inches apart, fixed J to f inch from the wall. A structure of a suitable 



description is represented in Fig 30. 



No plants must be grown in the case, 

 but the whole space ought to be devoted 

 to the trees. A border of 2 to 3 feet, not 

 more, should be kept clear in front of the 

 structure, into which the roots may pass. 

 It is best to train the trees entirely to a 

 roof trellis instead of the wall, which will 

 only be useful as a source of heat absorp- 

 tion and radiation, and in that respect be 

 of great value. 



Where walls exist they may be utilised, 

 but they are not needed for glass structures 

 in which fruit is to be grown, as warmth 

 in cold periods is better afforded by hot- 

 water pipes; and houses that enclose a 

 larger amount of air than do wall cases are 

 safer in cold periods. Wall cases, how- 

 ever, are useful aids in the culture of

to cover the top ventilating lights, the other to place over the remaining portion of the 

 roof. None is required for the front lights. Both pieces should have rings at the 

 corners and along the sides for placing over hooks fixed in the roof to prevent displace- 

 ment. When the material gets wet it must be dried, and always ready for an emergency.
