DESCRIPTION OF HOTHOUSES. 141 



But when it is intended to grow pines to 

 maturity by this practice, the pits may be made 

 much wider and deeper than those above 

 described ; and where the spot selected for the 

 pits is of a dry nature, the pits may be sunk 

 more in proportion, to give room for the larger 

 growth of the pines, between the bark bed and 

 the glasses, and when the pits are thus formed 

 for fruiting the pines, there can be no difficulty 

 in carrying the pipes all round the pit. 



By this method of growing pines in pits, 

 large quantities may be produced with greater 

 safety and with much less expense and trouble 

 thari many may imagine, and indeed where the 

 practice has not been witnessed, it would be 

 scarcely possible to form an idea, or at least 

 to become reconciled, that it is attended with 

 triumphant success ; but be it recollected, that 

 this is for the growth of pines alone, and there- 

 fore ought not to do away in large establishments 

 with the principal hothouse pinery, as it serves 

 so many other useful purposes, as well as being 

 an appendage of no mean consideration, where 

 forcing is carried on extensively.
