avoidably take place, for the pine in its own nature 

 requires at least twice the amount of atmospheric 

 moisture on the average that is advisable for the peach. 

 In these days of cheap glass, it would be much better 

 to build very small houses or pits. Such would answer 

 either as lean-to's or in the span-roof form, and might, 

 for economy's sake, be so compact, that all the opera- 

 tions necessary might be performed from the outside 

 by means of light sliding sashes ; the building of 

 course sunk very low. There would be no necessity 

 for a walk inside, unless desired by the proprietor. 

 The preservation of walks in the interior of forcing 

 structures often leads to much needless expense. 



Throughout the whole course of peach forcing, by 

 whatever mode or in whatever structure, much atmos- 

 pheric moisture must be secured, that is, providing 

 much artificial heat be indulged in. The only excep- 

 tions to this are two periods : the one whilst blos- 

 soming, the other whilst in the ripe state. For pot 

 culture, we apprehend that severe economy will, at 

 times, still cause them to be grown in pine-stoves, or 

 mixed up with other forcing. When such is the 

 xase, it will be expedient, after the fruit is gathered, to 

 use sulphur liberally on the the back of the leaf, pro- 

 vided the red spider has commenced operations.
