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 580 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 G. 



Table III shows the combined results of the two periods of 1014, 

 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 under the conditions that prevailed.

Table III shows the total and daily gains for each lot of hogs from 

 May 3 to October G, a period of 15G days. The gains varied with the 

 amount of grain fed. Lot 1 made G76 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
