clover and rye-grafs; the feventh, peafe; and the 

 eighth, barley. But this land lies near a large 

 town,* and had been mended with town-dung for 

 many years. I ploughed it as deep as the foil 

 would admit. The foil was a mixed one, confid- 

 ing of clay and under loam; and part of it had a 

 gravelly bottom, neither too dry nor too wet. 



It appears to me, that in many inftances, it is 

 the fbitable mixture of manures that makes the 

 improvement, rather than any thing elfe we can 

 account for. 



We find the chalk and clay are as poor foils 

 as any we know of: Yet I have found that by 

 mixing thefe properly, and laying fuitable quan- 

 tities on as poor land as any in EfTex, the land 

 yielded as good a crop as any I ever ploughed. 

 I am therefore of the opinion there might in the 

 fame manner be found a proper manure for our 

 ftirT clays; and when it is made rich enough, the 

 courfe of crops you have mentioned would do 

 very welL 



I am trying experiments to find a proper mix- 

 ture of manures for this purpofe; and when I 

 have fatisfied myfelf, I will inform you what it is.
