86 THE FARM DAIRY. 



which at 4 cents per pound would make the 

 skim-milk worth 25 cents per 100 pounds. 



In 1878 I made some experiments to show at 

 what age pigs made the most growth from their 

 feed. I began with pigs 12 days old, and of 

 course included the mother they were nursing, 

 the sow being fed corn-meal and wheat bran 

 with the skim-miJk. The corn-meal and wheat 

 bran were charged up at cost and the increased 

 weight of sow and pigs credited at 4 cents per 

 pound. On this basis I received for each ,100 

 pounds of skim-milk 23 4/5 cents. When these 

 pigs had reached the weight of 40 pounds they 

 gave me for each 100 pounds of skim-milk 56% 

 cents. Still later when they had reached the 

 weight of 125 pounds each and the work figured 

 upon the same basis as in the two experiments 

 just stated, charging the corn-meal and wheat 

 bran at $14 per ton, and giving the skim-milk 

 credit for the balance, I received 53% cents per 

 100 pounds for the skim-milk. 



As I had made many experiments with pigs 

 after they had reached the weight which these 

 had, I carried the lot no farther. 



I have used the work of Hoard, Goodrich and 

 myself to show that it is practical for an intelli- 

 gent farmer to do some work in experimental 

 lines. When this work was done I lived on my 

 farm and milked the cows, made the butter and 

 fed the calves and pigs myself.
