the fcarificated part continued much the 

 beft, the crop fuppofed to be 24 tons ; in 

 the whole 17 acres. It was before let at 

 I o J-. per acre. 



In February 1^60, another experiment 

 was tried on manuring in this method : A 

 grafs field was divided into three parts : 



N°. I. Was ploughed with a fcarificator, 

 and then manured with foap-afhes. 



2. Manured with foap-afhes, and 

 then ploughed with the fcarificator. 



3. Manured with foap-afh^s, and not 

 ploughed at all. 



In 1 76 1. 

 N°. I. Was much the befl. 



2. The next. 



3. The worft. 



In 1762, another trial was made on an- 

 other field of 17 acres, a gravelly foil, ma- 

 naged as before ; but the foap-afhes here 

 did not anfwer ; the fcarificating equally as 

 before. 



Thefe experiments are all clear in the 



refult, and cannot be controverted : 



you will however, doubtlefs recolledt, that 

 thofe made by Mr. Dalton at Sleningfordy

 of its work by ftones ; from whence we
