The variation that may occur between various analyses of ensilage 
are given by Professor Johnson, from seventeen analyses, as follows : 
Water, Ash. Alb. Crude Nit.—free Fat. 
fiber. extract. 
Minimum in 17 cases.......... 74, 2 0.8 0.9 4.7 7.0 0.3 
Maximum in 17 cases......... 84.9 1.8 1.9 7.9 13.0 0.9 
The difficulty. of sampling such a material as fodder corn or ensil- 
age so as to study the chemical changes which take place in the silo 
seems insuperable with our present methods, for Professor Johnson 
finding a difference of 3.39 per cent in the albuminoid of two dupli- 
cate samples of the dry material of fresh fodder corn, wisely comes 
to the conclusion that “these analyses demonstrate that this method 
of working is incompetent to give any clear notions as to the 
quantity or even as to the kind of changes that go on in the silo.” 
Our own analyses of ensilage of 1882, gives, as is noted in the 
preceding table, a difference of 2.56 per cent between the albuminoid 
of two samples of ensilage from the same silo, and corroborates Pro- 
fessor Johnson’s conclusion. We, however, give the result of analy- 
ses of the fodder corn and the same ensilaged, and Professor 
Johnson’s results for comparison, as indicating changes without 
proving the same for the reasons given.

The hay used in our experiments was of mixed grasses, some 
weeds, Timothy grass rather predominating, cut early. Our analysis

The potatoes used in our trials were small potatoes, White Star 
variety, the refuse of our crops, and just such as would naturally be 
fed ; the analysis differs somewhat from what would be yielded by 
merchantable potatoes on account of the greater quantity of skin in 
proportion to interior.
