374 THE FORCING GARDEN. [APR. 



It should be considered, that from this time the roots 

 have much to do, in sustaining and nourishing both 

 fruit and shoots, and so ought to be liberally sup- 

 plied with water. If the border were well soaked, 

 both inside and outside of the house, once a-week 

 or ten clays, with that nectar of vegetable life, the 

 drainings of the dunghil, the roots would be much 

 invigorated *. 



The use of the engine may now be resumed once 

 in two or three days, for the suppression of the red 

 spider ; applying it with force. In the intervals or 

 these waterings, the house may be steamed in the 

 evenings, as long as" the state of the weather re- 

 quire the flues being made so hot as to produce steam 

 in any considerable quantity. 



Look out for the thrips, as directed above, when- 

 ever the young leaves, or points of the shoots be- 

 gin to turn brown or curl up. The remedy lies in 

 the fumigating bellows, when charged with tobacco 

 and a live^cinder, if the directions on this subject, 

 already repeatedly given, be followed. I must fur- 

 ther observe, however, that fumigations should be 

 performed before the fruit begin to swell off, or co- 

 lour, as it might otherwise be tainted by the smoke. 



* I have practised this kind of watering to a great extent, in 

 every species of forcing, with much success and satisfaction. 

 To all plants forced in pots, it is eminently useful. When the 

 pool at the dunghil has been dried by evaporation in hot wea- 

 ther, I have often laid dung in steep or soak, in order to enable 

 me to continue such watering.
