portions of wheat shorts. Speaking generally from the results obtained, the mixture 

 of riee-meal and shorts is very little better than straight rice-meal and cannot be 

 eomijared in regard to usefulness with oats, peas, barley, and shorts. 



The same trouble was experienced in lot 3 as in lot 1, but it did not occur quite 

 as early in the feeding period. The history of lot 3 is as follows : In pen 3, the pigs 

 became fat but looked rough and had dark-coloured skins, but they did not show signs 

 of weakness in the hind-legs until the eighty -third day, after w^hich time they all went 

 down and they were immediately killed. Pen 7 of this lot showed the first symptoms 

 of trouble at fifty days, and at the 64th-day stage none could walk.' and they were 

 killed before they had finished their 100-day period. 



The controls in lot 4 behaved very differently. Pen 4 did not begin to gain as 

 rapidly as did pen 3 in lot 3, but the pigs always appeared in better condition. The 

 last week of the period they made better gains than in any previous week. They were 

 killed the same time as pen 3 of lot 3, and thus lost, to the advantage of that pen, their 

 best jjroducing period. They never missed a meal; they were always hungry, and were 

 in perfect health when killed. The pigs in pen 8, lot 4, were from the same litter as 

 those in pen 7, lot 3, and were 2 pounds heavier at the beginning, but the pen 7 pigs 

 were the most robust looking. Instead of killing this pen when the ones they con- 

 trolled went under, they were kept the full period to see if, by any chance, they could 

 be pushed off their feet. At the end of 105 days, or 41 days longer than their rice-meal 

 mates, they were still healthy and in perfect condition. 



The same can be said of pen 15. They started slowly, grew for a long time, then 

 began to fatten, and, for the whole period, they were in perfect health and were in 

 show condition when killed. 



Comparing lots 3 and 4, the cost of production differs but little. Lot 3 could only 

 stand, on an average, 77-5 days' feeding; while lot 4 averaged 98-6 days and gave 

 first-class block pork, as compared to having lot 3 pork condemned. This makes the 

 very great difference in the two lots.
