The northern field corn ensilasre was not analyzed after it 

 was put in the silo, but from the analyses of last year I have 

 placed in the table figures that will not vary much from the true 

 analysis 



The cost per ton as harvested was as follows :* 



Southern corn, $2.21, shrinkage in silo 16.5% 



Sanford, 2.48 " " 5.5% 



Northern field, 2.40 " " 23.% 



The shrinkage of the Northern field corn is excessive, part- 

 ly due to freezing to side of silo, and partly to a defective bot- 

 tom of material left over from last year's filling : as nearly as 

 eould be estimated these accidental losses would reduce the act- 

 ual shrinkage to 209^-. 



The actual cost then per ton as fed out would be as fol- 

 lows : Southern, $2.64; Sanford, $2.62 ; Northern, $3.00. 



The price per ton for grains as figured from the market 

 price of last winter was : 



Corn and oats (mixed grain), $26.00 per ton. 



Gluten meal, 26.00 " 



Corn and cob meal, 20 00 " 



Buckwheat, 20.00 " 



Corn fodder and bean vines, 5.00 " 



Mixed hay, 8.0c " 



Millet, 5.00 " 



I have based the price of hay on the market value here in 

 the barn, choice hay selling for $9.00, but this being the first 

 year's crop was of less value on account of the old stubble 

 which it contained. The corn fodder, millet and bean vines I 

 have rated at $5.00, which is slightly more than they would sell 

 for but is very close to their actual feeding value as compared 

 with hay at the above mentioned price. With these figures as 

 a basis we are in position to determine the cost of milk and 

 butter with our own herd and under our own conditions, and 

 also to note how a change of food affects the cost of the prod- 

 uct. 



The silo was opened in November and the whole herd 

 were accustomed to the ensilage before the experiments were 

 started.
