132 DESCRIPTION OF HOTHOUSES, 



flue can be carried along between the two pits? 

 lengthways, as before named. But the plan te 

 be most recommended, both for convenience and 

 appearance, and I may add, success, is to have 

 one pit only in each house, and to have the suc- 

 cession house or houses built at one end, or both 

 in one range, to correspond with the main pinery? 

 divided inside by a partition of glass-work only. 

 This will be very advantageous, both for raising 

 the young plants, and also to forward the whole 

 of the succession, until they arrive at a proper 

 age and strength for placing finally in the main 

 pinery for fruiting ; or when a succession house 

 is built detached from the principal pinery, the 

 same form of building as the latter will likewise 

 suit for the former, although generally of less 

 dimensions. Having seen much practice with 

 steam and hot water, I may here observe that I 

 intend under the head of steam and hot water, 

 to give a more comprehensive opinion relative to 

 heating pineries ; and before I finish this treatise 

 I intend to spare neither pains nor expense in 

 order to become thoroughly satisfied in every 

 particular relative to the properties of hot water
