432 Account of Count Zu bow's Steam-House. 



I doubt, notwithstanding, whether Pines thus planted out, 

 will fruit so well as those in pots. I consider the earth, saw- 

 dust, or whatever other materials the pit may be filled with, 

 as only the medium through which heat is conveyed to the 

 pots, and that, of course, it ought to be calculated for the 

 salubrity of the plants. 



I am at this time constructing a steaming apparatus on the 

 above plan ; but, instead of a wooden reservoir, I make it of 

 brick-work, and, instead of the upper planking, I am trying 

 a perforated brick arch.
