60 THE FORCING GARDENER. [B.I. 



water be poured on the flue every evening 

 when the fire is ftrongeft ; which will 

 caufe a fine agreeable fteam * to arife in 

 the houfe, greatly to the benefit of the 

 flowers and foliage : For at this time, 

 water from the engine cannot, with pro- 

 priety, be applied, left the tender bloflbms 

 might be injured. 



Soft and tempered water fhould be ufed 

 at all times, and on' all occafions.

* I do not confider the Cherry houfe of fuch impor- 

 tance as to be at the expence of erecting {teaming appa- 

 ratus purpofely for its ufe ; nor, indeed, do I think it 

 worth the while to do fo for the ufe of any kind of for- 

 cing, except a range of peach houfes : in the near 

 neighbourhood of which were it placed, a pipe might 

 (if at a fmall expence) be borrowed for its ufe. But, 

 at all events, I prefer fteam which is produced from ai* 

 earthen flue, to that produced from boiling water.
