1 Price of feed and pasture: Cottonseed cake, $30 per ton: pasture. SI per head per 2S-day period. 
The first section of Table 11. giving the results of the 1914 work, 
shows it required 126 pounds of cottonseed cake in addition to the 
grass the steers in Lot 1 received to make 100 pounds gain, which 
cost $3.20 per hundredweight. The cattle in Lot 2 required 120 
pounds cottonseed cake fed with grass to make 100 pounds gain at a 
cost of $3.03 per hundred pounds gain. The gains on the cattle in 
Lot 3, fed for a period of 165 days, cost $1.55 per 100 pounds, or just 
about one-half as much as where cottonseed cake was fed. The 
winter-grazed cattle (Lot 4), which were grazed during the summer 
for 177 days, made 100 pounds gain at a cost of $1.93. The gains 
were made much cheaper where no cottonseed cake was fed, there 
being very little difference in the cost of the gains in Lots 1 and 2, 
where cake was fed to both lots. 
The second section gives the quantity and cost of feed required 
to make 100 pounds gain in the 1915 test. It cost $1.16 to put 100 
pounds gain on the grass-finished cattle of Lot 1, division "a," these 
cattle making the cheapest gain of any of the grass- fed cattle. The 
cattle in Lot 1, division " b," made 100 pounds gain at a cost of 
$3.63, which were the most expensive gains made. The grass-finished 
cattle in Lot 2, division " a," made 100 pounds gain at a cost of
