i Price of feed and pasture: Cottonseed cake, $30 per ton; pasture, $1 per head per 23-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
