the Workmen to introduce any newlnflrument: 

 Indeed, feeing little is to be expected from thofc 

 who have been long attached to different Me- 

 thods, the fureft Way to promote the Ufe of it, 

 is to engage young Perfons, who may probably 

 be better difpofed, to. make the Trial at their

 thefe are ufed to hoe Corn, the Board on the

 Board, muft be taken off; otherwife fo much 

 Earth will run to the Left Side, as to injure the 

 Crop when it is low. , 



The Drills are excellent Inftruments; yet we
