sulphate of potash (95 per cent.), with 600 pounds of fine- 

 ground bone ; in the other, 400 pounds of muriate of potash 

 (80-82 per cent.), with 600 pounds of fine-ground bone. 

 The same amount and kind of manure were applied for rais- 

 ing vetch and oats and vetch and barley. The field occupied 

 1>Y these crops was ploughed, manured, harrowed and seeded 

 down, as far as practicable, at the same time. The seed was 

 sown in all cases April 20. Four bushels of oats with 45 

 pounds of vetch were sown, as on previous occasions, while 

 3 bushels of barley were used, with 45 pounds of vetch, in 

 case of barley and vetch. Both crops came up May 4, and 

 were of a uniformly healthy condition during their subse- 

 quent growth. The barley began to head out June 20 ; the 

 vetch was at that time beginning to bloom. The crop was 

 cut for hay June 23. 



Yield of Barley and Vetch per Acre. 



In case of muriate of potash and bone, . . 5,737 pounds of hay. 



In case of sulphate of potash and bone, . . 5,077 pounds of hay. 



The oats headed out June 25 ; the vetch was fairly in 

 bloom. The crop was cut for hay July 2. 



Yield of Oats and Vetch per Acre. 



In case of muriate of potash and bone, . . 8,051 pounds of hay. 



In case of sulphate of potash and bone, . . 7,088 pounds of hay. 



1895. — During that year the observations of the pre- 

 ceding year were repeated and in some directions enlarged 

 upon. Aside from mixed forage crops of vetch and oats 

 and vetch and barley, there were raised crops consisting of 

 oats, vetch and horse bean and of oats and lentils. The 

 field used for these experiments had been used during the 

 preceding season either for the cultivation of potatoes or 

 of vetch and oats. In both cases it had been manured, per 

 acre, with either 400 pounds of muriate of potash and 600 

 pounds of fine-ground bone, or with 400 pounds of sulphate 

 of potash and 000 pounds of fine-ground bone. The same 

 kind and the same quantity of manure were applied in 1895. 

 The field was ploughed April 25; the manure harrowed in
