196 THE PRACTICE OF THfi 



" (hillings an acre: Thus it appears, that, irt 

 " every fifteen years the fee-limplc of all the

Mr. Baker was a very accurate experimen- 

 ter, and had experience of horte-hoeing feveral 

 crops, turnips cabbages, &c. in whi-h lie 1uc-

 impoverished, and the crops muft decline.
