ble material in the two cases to be made up by a larger amount of 

 grain. In this way both lots of sheep would receive the benefi- 

 cial effect upon health and appetite which green food is supposed 

 to give, and we would be studying the single question of the rela- 

 tive value of roots and grain. Consequently the ration of the 

 two lots of sheep were planned as nearly as possible so that each 

 lot received the same amount of digestible material, the difference 

 being that more of this material came from grain in the one case 

 and more from turnips in the other. The feeding of the sheep 

 was begun on December 23. The rations were as follows : 



20 lbs. Hay, mostly Timothy. 

 Lot 1, { 12 lbs. Mixed Grain. 



20 lbs. Cut Rutabagas. 



20 lbs. Hay. 

 Lot 2, -{ 7 lbs. Mixed Grain. 



50 lbs. Rutabagas. 

 The mixed grain consisted of three parts gluten meal, two parts 

 corn meal and one part wheat bran, by weight. This feeding 

 period was continued until Jan. 30. It is seen that in this period 

 Lot 1 ate five pounds more of the mixed grain each day than Lot 

 2, and that Lot 2 ate 30 pounds more of turnips daily than Lot 1, 

 or in other words, five pounds of mixed grain were against 30 

 pounds of turnips, it being calculated that the amount of digesti- 

 ble material would be about the same in the two. The animals 

 were weighed first on December 29th and 30th, and again on Jan. 

 29th, and 30th. The following table shows the amount of food 

 eaten and the gain of each lot of sheep.

It appears by the above that Lot 1, receiving the more grain, 

 gained 97 pounds, and Lot 2, receiving the more turnips, gained 71 

 pounds, a difference of 25 pounds. It is fair to conclude, then, that 

 the five pounds of grain produced more increase in weight than the
