third month. The cows in lot I. put on flesh from the 

 beginning- of the experiment, the explanation, no doubt, 

 being that the heavy ration was given to them at a time 

 when they were already beginning to go off their milk. 

 Taking the whole period during which the cows were under 

 experiment, lot I. gained on the average, 53 Ib. per cow, and 

 lot II. 16 Ib. per cow.
