Substances like No. I. pay best as concentrated food for 

 farm-stock : the large percentage of fat, and the high rate 

 of digestibility of animal matter, like flesh, promise excel- 

 lent results in a rational system of stock-feeding. The time 

 is not very far off when many of our animal refuse sub- 

 stances will be better economized by feeding them to our 

 live-stock before they serve as plant-food.
