WEIGHTS AND GAINS. 
The calves used in this experiment were raised on tick- free pastures 
and weighed over 400 pounds each, being somewhat heavier at wean- 
ing time than the calves used in previous tests. They were of about 
the same quality and breeding as the calves used in former years. 
They were put on a preliminary feed from October 25 to November 
13. and during that time they were dehorned and the males castrated. 
The calves were weighed individually on three consecutive days 
and an average was made of all weighings and used as the initial 
weight. The regular feeding period began November 13, 1914. Each 
lot of calves was weighed every 28 days during the test, and all 
calves were weighed individually at the close of the test. The calves 
were weighed about 10 o'clock each weigh day.

The calves of lots 1, 2, and 3 were about the same size at the be- 
ginning of the test, averaging 437, 427, and 436 pounds, respectively. 
During the entire feeding period of 143 days the calves in each lot 
made a total gain of 245, 268, and 227 pounds per head, or an aver- 
age daily gain of 1.71, 1.87, and 1.59 pounds per head. The gains 
for the first two lots were very satisfactory for calves of this size and 
quality. The gain for lot 3 was not so satisfactory, but when the 
daily rations of the calves are considered it is seen that the calves of 
lot 3 did not get as valuable a grain ration as those of lot 2, if the 
theory is true that one pound of cottonseed meal is equal in feeding 
value to two pounds of corn for fattening calves. 
QUANTITY AND COST OF FEED REQUIRED TO MAKE 100 POUNDS 
OF GAIN. 
Figures showing the amount of different kinds or combinations of 
feeds required to make 100 pounds of gain in weight are of most 
importance to prospective feeders. When a feeder knows the valua-
