 except on fruiting plants, and just in the hot summer 

 months, when the situation of the plant ought to be 

 very near to the glass, they do not seem calculated 

 for general practice. 



However, as some persons are inclined to suppose 

 that Pines raised by these methods are generally of

 first method, of setting the pot in water, is greatly to 

 be preferred, and that the best time for adopting it 

 is immediately after the plants have shown fruit in 

 the spring. 



Hot-houses are now in general use, and the cul- 

 ture of the Pine-apple is, in some sort, understood 

 by almost every gardener, not one of whom but 

 concurs in lamenting the injury to which this plant 

 is liable from two species of insects, which are ge-

 figures of each : to these I have added the Coccus 

 Hesperidum, it being also generally found upon the 

 Pine-apple plant. 



I esteem myself greatly indebted to my late very
