barley during the period and made 435 pounds of gain. In lot 5. 
which was fed 3 per cent corn, there were 11 pigs, having a total 
initial weight of 771 pounds. Owing to shortage of pasture, one pig 
weighing 135 pounds was removed August 22. On September 9 six 
more pigs, with a total weight of 589 pounds, were removed. Lot 5 
was fed 2,202 pounds of corn during the period and made a total gain 
of 735 pounds. The experiment closed on October 6. 
Table III shows the combined results of the two periods of 1914, 
calculated to an acre basis. The results for the first period were not 
what could be expected under favorable conditions, since the hogs 
used were rather inferior and the outbreak of cholera did some dam- 
age. The hogs used during the second period were fairly good stock 
and the results should be fairly dependable. It is thought also that 
the combined results of the two periods give a reliable indication of 
the effects of feeding different quantities of grain, as well as showing 
what was possible imder the conditions that prevailed.

Table III shows the total and daily gains for each lot of hogs from 
May 3 to October 6, a period of 156 days. The gains varied with the 
amount of grain fed. Lot 1 made 676 pounds of gain; lot 2, 1,520 
pounds; lot 3, 3,036 pounds; lot 4, 2,780 pounds; and lot 5, 4,416 
pounds. The daily gains per acre as shown in Table III varied from 
4.33 pounds in lot 1, which received no grain, to 28.3 pounds in lot 5, 
which received approximately a 3 per cent ration of corn. Lot 5 
made 3,740 pounds more gain per acre than lot 1. Lot 5 was fed 
13,352 pounds of corn, while lot 1 received no grain. The 3,750 
pounds of gain, therefore, can be credited to the use of 13,352 
pounds of corn ; that is to say, each 100 pounds of corn fed resulted 
in the production of 28 pounds of pork, whereas when hogs are fed 
corn alone 18 pounds per 100 pounds of corn is considered a satis- 
factory gain. The hogs in lot 5 paid $1.96 per hundredweight for
