meal wet with water; lots 2 and 6, 3 pounds of potatoes to 1 of corn 

 meal ; lot 3, 3 pounds of potatoes to 1 of shorts, and lot 4, 2 pounds of 

 potatoes to 1 of corn meal. The first four lots contained three pigs 

 each; lots 5 and C, two each. Tables show the food consumed, 

 weights of animals, and food consumed per 100 pounds of gain for each 

 lot. 



It was found that the hogs ate the cooked potatoes best when there was the least 

 water in the mashed potatoes. * * * Seven hundred and eighty-nine pounds of 

 potatoes took the place of 178 pounds of corn meal. To effect a saving of 100 pounds 

 of corn meal, 443 pounds of potatoes would be required. From this we see that it 

 required nearly 4 J pounds of potatoes to take the place of 1 pound of corn meal. This 

 makes a bushel of corn worth about 4^ bushels of potatoes. * * * It appears thnt 

 the dry matter of corn was superior to an equal amount in potatoes for making gain 

 with these hogs. The trial with shorts and potatoes shows that shorts did not give 

 quite as good results with the potatoes as did corn meal. 



Ground oats versus bran for milk and butter production, 

 F. W. WoLL, M. S. (pp. 65-89). — Two separate experiments, one of 8 

 weeks and the other of G weeks' duration, were made to compare the 

 value of ground oats and bran when fed to milch cows. "Two cows 

 wei'e used in the first experiment and four in the second. The cows 

 were fed the same quantities, by weight, of oats and bran, 8 i^ounds 

 daily per head in the first experiment and 10 pounds in the second, 

 and in addition, the same fundamental ration of corn meal, hay, and 

 corn silage or fodder corn. The effect of similar weights of oats or 

 bran in a ration for milch cows was thus studied." 



The live weight of animals, water drank, yield of milk and fat, aver- 

 age yield of the same and of butter, and amounts of milk, fat, and butter 

 l)roduced per pound of dry matter consumed on each ration, are given 

 for each feeding trial, together with the viscosity of the milk and the 

 number of fat globules for the first ex[)eriment, and a general summary 

 for the two experiments taken together are stated in tables. The deter- 

 minations of the fat globules in the milk, which were made in the first 

 experiment, showed that the number of fat globules i- • isod on the 

 oat feed, and their relative size decreased correspondingly. 



From the two experiments the author draws the following tv^nclu- 

 sions: '• '^ 



"(1) With a ration of 10 pounds, per day and per head, of ^i6j:^A 

 oats or of bran, fed in connection with the same ration otherwise, there 

 was a 10 per cent greater yield of milk and milk fat on oats than on 

 bran. 



"(2) At the present prices of the two feeding stutfs [bran $11 aud 

 oats $17.40 per ton] bran is the more economical food for milch cows."

 production, F. W. Woll, M. S. (pp. 80-97). — In continuation of 

 experiments on this subject, duplicate experiments were made 1889-90, 

 each with four cows and of 6 weeks' duration, the time being divided 

 into two equal periods. In each experiment, in addition to the ration
