It was proposed to compare the yield, as far as quantity 

 and quality are concerned, under otherwise corresponding 

 circumstances. Three varieties of potatoes. Beauty of 

 Hebron, Clark's, New Queen, were chosen for the trial. 

 The seed potatoes were obtained of J. J. H. Gregory & Son, 

 Marblehcad. 



Two plats, 15 and 16, were assigned for the cultivation of 

 Beauty of Hebron ; two, 13 and 14, for that of New Queen ; 

 and two, 11 and 20, for that of Clark's variety. 



One plat in each case received its potash supply in form 

 of muriate of potash (plats 11, 13 and 15), and one in each 

 case in that of high-grade sulphate of potash. 



The actual amount of potassium oxide used in all cases 

 remained the same.
