256 A TREATISE OF 



roots are not covered above an inch deep | 

 this done, if the foil be a clay, cover the 

 part thus opened with coal afhes, fifted 

 fine, about one fourth of an inch thick, 

 or with lime fomewhat more fparingly; 

 then from the fame compafs of the furface 

 of the border, as direfted for the firft 

 opening, take as much earth as will cover 

 the part thus manured about three inches 

 thick, and what earth remains on that 

 laft opened, more than an inch deep above 

 the roots, muft be taken away; otherwife 

 it will be of as ill confequence as planting 

 too deep, by depriving the roots of a fuffi- 

 cient heat from the fun. 



Trench the borders in this manner all 

 over ; and if they are too narrow, add to 

 their breadth where it can be done. 



For foils of a fandy loofe nature, foot is 

 the moft proper, and muft be ufed in the 

 fame manner as before dire6led for aflies 

 on clay ground 5 or for want of foot, 

 pigeon dung, about half the quantity : and 

 if thefe things are done in the fummer, 

 or when the earth is dry, water plentifully 

 in the evening all that has been trenched 

 that day.
