1. The yield of potatoes is in every instance larger in 

 case sulphate of potash has furnished the potash of the fertil-

 purpose. 



2. The yield of the three varieties of potatoes on trial, 

 although raised under a corresponding system of cultivation 

 and of manuring, differs seriously. Beauty of Hebron pro- 

 duces nearly one-sixth more in weight than the New Queen 

 variety, and one-third more than the Clark variety. 



Plats 12, 17, IS, 19 and 21, which remained in grass in 

 previous years, received as top-dressing, muriate of potash, 

 200 pounds, and ground bone, 600 pounds, per acre, at an 

 early date in the spring, 1893. The grass was cut June 27 

 and 28. As the weeds began to infest the plats, the experi-

 sod turned under during the month of August. Dry lands
