the sun is out warm. The inside border should receive 

 frequent and ample supplies of water. In a dry time the 

 outside border should also be freely watered. 



Regulating the Temperature. When the temperature 

 exceeds ninety to one hundred degrees, air should be ad- 

 mitted at the top, and, if necessary, at the bottom. The 

 admission of abundance of air is one of the important

To Prevent Mildew. This may be looked for in July.

 rate of one pound for every twenty square feet ; and if the

The advantages of glass structures for the growing of

By it the owner of a small garden or city lot can secure 

 to himself a large amount of fruit grown in a small space, 

 and at a time when it cannot be purchased. 



To the commercial fruit-grower the orchard house of-

 nurseryman it is becoming yearly more and more a neces- 

 sity, toward testing the correctness of new varieties from 

 which to propagate. 



The construction of an orchard house is similar to that
