At the close of the season (1892) it was decided to raise 

 hereafter other crops than grasses upon phits 11, 13, 14, 15, 

 16 and 20. For this reason they were phniiihed after the 

 rowen had been secured, while plats 12, 17, 18, 19 and 21 

 remained in grass for another season. 



2893.— Vhits 11, 13, 14, 15, 16 and 20, which had been 

 used for several preceding years for the production of 

 grasses, were at an early date prepared to serve for experi- 

 ments with several prominent varieties of potatoes. They 

 were ploughed in August, 1892, and w^ere again ploughed 

 for the final preparation April 25, 1893. 



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

 and quality are concerned, under othersvise 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, Marblehead. 



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 (plats 14, 16, 20). 



The actual amount of potassium oxide used in all cases 

 remained the same.
