per 100 pounds ; with the same price for grain and dressed 

 pork at G cents per pound, skim-milk would return 31.5 

 cents per 100 pounds. 



With grain at $18 per ton and skim-milk at 15 cents per 

 100 pounds, live weight would cost 2.88 cents per pound 

 and dressed weight 3.66 cents. If skim-milk were reckoned 

 at 25 cents per 100 pounds, live weight would cost 4 cents 

 per pound and dressed weight 5 cents per pound. 



Details of the Exiierhnent. 



The object of the experiment was to compare the nutritive 

 effect of rice meal with corn meal when fed in connection 

 with skim-milk. Six pigs, grade Chester White, all out of 

 the same litter, were selected. They were received October 

 15, when six weeks old, and kept for a month before begin- 

 ning the experiment. Before starting the experiment each 

 pig was placed in a separate pen, of about 100 feet area. 

 The pens were separated by heavy galvanized wire, thus 

 securing good ventilation, and allowing at the same time the 

 animals to see each other. While the}^ had no outdoor run, 

 the pens were large, the room airy and well lighted, and the 

 constant good health of the animals indicated no disturbing 

 influences. Only in very severe weather did the tempera- 

 ture in the building fall a little below freezing. 



Feeding. — The animals were fed three times daily, the 

 slightly warmed milk being measured, and the grain ration 

 for the twenty-four hours accurately weighed. The pigs 

 were each given from 5 to 6 quarts of milk daily. At the 

 beginning of the experiment 4 ounces of grain were given 

 with each quart of milk ; and the amount increased from 

 time to time, to suit the appetites of the animals. The 

 feed was consumed during the entire time, without a single 

 refusal. 



Feeds. — The skim-milk was tested occasionally, and 9.75 

 per cent, of solids were used in calculating the amount of 

 dry matter it contained. Rice meal is fed and highly 

 prized in Europe. It is occasionally found in our markets, 

 but the present low price of corn meal excludes it. In pre- 

 paring rice for human consumption, various mechanical proc- 

 esses are employed. After the hull is removed, the rice is
