ply supplied with water ; especially in such where 

 the roots of the plants have filled the whole pit, and 

 have reached to the bottom of the soil in the bor- 

 ders. Water must be given, in such a case, so plen- 

 tifully as to reach the extreme fibres of the plants, 

 both with respect to latitude and depth. 



The plants may now also be refreshed over the 

 foliage, either by the syringe or by the engine, 

 once in two or three days; scourging such as exhibit 

 any appearance of the red-spider with force, in or- 

 der to prevent its ravages and baneful effects. 



If the green-fly or the thrips make their appear- 

 ance, recourse must be had to fumigations, in the 

 manner formerly directed ; of which see February. 

 In order to clean the plants of the coccus, if trou- 

 bled with it, they may be washed with soap and wa- 

 ter ; and that at any season j of which see also Fe- 

 bruary. 



Of training the Climbers. 



The climbing plants should be regularly and neat- 

 ly trained to the rafters, as they advance. They 

 should not be allowed to spread much over the sashes, 

 otherwise they would shade those in the borders too 

 much. The rafters, for this purpose, should be fit- 

 ted up with two or three rows of wires, longitudi- 

 nally, to which the shoots might be dressed.
