PBEFACE. 



SEVERAL cogent reasons might be adduced for writing 

 the present work, the chief being a deep conviction 

 that something of the kind was really needed, to show 

 the best arid 'most economical way of constructing 

 glass-houses, pits, &c., and the most desirable angle on 

 which to pitch the roofs of them, according to the 

 particular class of plants to be grown ; as well as the 

 best aspect in which to place such houses. It will be 

 observed that all my angles for fruit-growing are at a 

 very sharp pitch. This is, I think, most desirable for the 

 production not only of fine fruit but also for the kind 

 of wood that will ensure a good crop of fruit, especially 

 in the case of Peaches, Plums, and Grapes. 



I am fully convinced of the necessity of a work like 

 this for nearly all classes who require sound informa- 

 tion both for building glass-houses and for their sub- 

 sequent adaptation. My method of double-glazing will, 

 I think, meet a want long felt, and no doubt will be 

 generally adopted for early forcing ; my vine border- 

 protector will also doubtless supersede the usual method
