CH. 5-] GRAPES. 



fary here as in the cherry or peach houfe ; 

 nothing being more conducive to the 

 health of the plants, than frequently to 

 fprinkle their foliage with water. Beiides, 

 by throwing it with fome force, infects 

 are thus deftroyed, and their breeding 

 prevented. By a proper application of 

 the engine, endeavour to render the plants 

 quite clean of infects, particularly the red 

 fpider, before the fruit begins to ripen off, 

 as, after this time, it is not advifable to 

 water the foliage, on a double account, 

 viz. left, by moifture hanging about the 

 clufters, the berries might rot through 

 damp, and alfo become infipid in flavour. 



In the interim of wafhing, fteam every 

 night when the fire is at the ftrongeft, by 

 pouring * water on the flues till an object 

 cannot be feen at the diftance of two or 

 three yards : and repeat this early in the 



morning, 

 



* In another part of this work, I have already hinted, 

 that I do not think it worth the while to erect the fleam- 

 ing apparatus for any fpecies of forcing, except peaches. 

 For the Grape-houfe, it would be extravagant ; as fteam 

 can be produced there at any period of forcing, efpeci- 

 ally in the flowering feafon, when a ftrong fire heat is 

 recniifite at any rate.
