I am now feeding my own pigs on malt-combs, bran and 

 corn-meal. The malt-combs cost fifteen cents a bushel, weigh- 

 ing about twenty-five pounds, or $12 per ton. The bran costs 

 $22 per ton. The corn-meal $38 per ton. We mix about one 

 hundred pounds of malt-combs, fifty pounds of bran, and fifty 

 pounds of corn-meal with eighty gallons of water, and steam 

 it till well cooked. This mixture contains about seventy-five 

 per cent, of water, or about as much as green clover. 



Pigs from six to eight months old eat about twenty pounds 

 of this mixture each per day, and gain about eight pounds 

 per week. The pigs eat each per week seventeen and a half 

 pounds of malt-combs, eight and three-quarters pounds of 

 bran, and eight and three-quarters pounds corn-meal. The 

 food, therefore, costs thirty-seven and a half cents per week. 

 I think the eight pounds of increase in live weight would be 

 equal to si^ pounds of dressed weight carcass, so that each 

 pound of dressed pork costs me six and a half cents per 

 pound. But what of the manure ? 



The manure from 17^ lbs. of malt-combs is worth 26^ cents. 



Total, 



In other words, I am getting forty-one and three-quarters cents' 

 worth of manure from each pig per week, the food of which 

 costs me thirty-seven and a half cents. 



I thought I was making a fair profit out of my pigs ; but I 

 did not know till my foreman and I made the foregoing calcu- 

 lations, that we were doing quite so well. The figures have a
