CH. 9.] PINES. 



See Section XII. on the culture of the 

 grape. 



SECTION II. 



On the Preparation of the Bark-Bed. 



THIS is an article of much confequence 

 to the welfare of the plants ', and if 

 not judiciouily performed, is productive of 

 great evil. It is no uncommon thing to 

 hear of whole pits of Pines being burnt 

 at the root by the over-heating of the 

 bark-bed; and Mr Speechly and others 

 give this as a principal reafon for their 

 ufing oak-leaves. I have grown Pines for 

 many years, and can declare that I never 

 had the roots of a fingle plant injured by 

 bark-heat ; and if my method of prepara- 

 tion is ftridly followed, I can be bold to 

 augur that none ever will. The manner is 

 the molt fimple imaginable. 



My opinion, in refpect of the quantity 



and quality of bottom heat required by 



the Pine, has been different from that of 



any other author I have read on the fub- 



M jeft.
