 dirty fermenting substances, which corrupt the purity of the 

 atmosphere. 



The accompanying plan of this system as applied to Melon 

 Pits, will at once show its applicability and economy, and as 

 I am now engaged in erecting a great number of them in 

 various forms, I may at some future opportunity favor my 

 transatlantic friends with plans exemplifying other applica- 

 tions of this mode of heating. — R. Glendenning.
