Comparing corn-stalks with the mixed hay, when supplemented by 280 lbs. 

 of corn meal and 392 lbs. of bran, we find : 



2,374 lbs. of corn-stalks yield 1,120 lbs. 12 oz. milk, making 57 lbs. 0% oz. butter; 

 755 lbs. mixed hay yield 1,063 lbs. 15 oz. milk, making- 56 lbs. 1% oz. butter ; 



or, 56 lbs. 13 oz. milk and 15 oz. of butter more from the stalks than from the 

 mixed hay. 



Comparing corn-stalks with clover hay, as in the previous instance, we find : 



1,867 lbs. corn-stalks yield 1,079 lbs. 3 oz. milk, making- 52 lbs. 2% oz. butter; 

 642% lbs. clover hay yield 1,059 lbs. 1 oz. milk, making 54 lbs. 8% oz. butter; 



or, 20 lbs. 2 oz. more milk, and 2 lbs. 6 oz. less butter from the corn-stalks than 

 from the clover hay. 



Taking into consideration the fact that the milk and butter yield are both 

 larger from the stalks than from the mixed hay it is fair to say that the corn- 

 stalks were worth one-third as much as the mixed hay ; that is, one ton of 

 mixed hay is worth three tons of stalks, fed as these were. 



From the second trial we see that one ton of clover hay was worth some- 

 what more than three tons of corn-stalks, fed as described. 



In the two trials 4,241 pounds of stalks were fed, and 1,450 pounds weighed 

 back as coarse parts that the cows refused to eat. This is over 34 per cent, of 

 the whole amount of the stalks, by weight, lost by feeding in this manner. 

 Whether the part thus lost is proportionally as valuable as that eaten, and what 

 amount can be saved by passing the stalks through a feed cutter is work for 

 future experiments. 



Arranging our figures in another form we have the following : 



Food required for 100 pounds of milk when feeding corn-stalks: 

 193 pounds of corn-stalks. 

 25 pounds of corn meal. 

 35 pounds of wheat bran.
