turned yellowish, July 18. The remainder of the crop was 

 then cut for hay. The total yield of the crop, counted as 

 green fodder, with 20 per cent, of dry vegetable matter, 

 amounted to 21,000 pounds per acre. Buckwheat was sub- 

 sequently raised upon the same field as fall crop. 



1894. — The field in this case was 700 feet long and 75 

 feet wide, equal to one and one-fifth acres (corn was raised 

 upon it in 1893). It was ploughed Oct. 25, 1893, and ma- 

 nured with barn-yard manure at the rate of ten tons per acre ; 

 and was ploughed again April 18, 1894, and harrowed and 

 subsequently seeded with oats and vetch, as described in the 

 preceding experiment, using 4 bushels of oats and 45 pounds 

 of vetch per acre. The seeds were, however, sown at two 

 different times, to extend the period of the fitness of the crop 

 for green fodder. The seed sown on the northern portion 

 April 20 came up April 28. The southern portion of the 

 field was seeded May 11, the plants appearing above ground 

 May 19. The crop made a very satisfactory growth, and on 

 June 23 the feeding of the green material from the northern 

 portion began (the vetch being in bloom and the oats head- 

 ing out), continuing until July 2, when the remainder was cut 

 for hay. July 6 the cutting from the southern portion began, 

 continuing until the 18th, when that remaining was cut for 

 hay. Following is given a statement of the yield from the 

 field : — 



Pounds. 



Green material fed (19.12 per cent of dry matter) , . 6,875 

 Hay of vetch and oats (73.66 per cent, of dry matter), 4,980 



July 21 the field was ploughed and prepared for raising 

 upon it, as a fall crop, Hungarian grass. 



During the same year (1894) other observations of a simi- 

 lar character as previously described were carried on in other 

 parts of the farm. 



It was decided to compare the effect of muriate of potash 

 and sulphate of potash on mixed crops, consisting of oats 

 and vetch and of barley and vetch. The field used for this 

 observation consisted of a light loam. It had been used 

 during the preceding season for the cultivation of different 

 varieties of potatoes, and had received as manure on that 

 occasion, per acre, in one case, 400 pounds of high-grade
