and sour whey. The first test was made with 3 lots of 3 pigs each. 

 After a preliminary period of 7 days, during which all the lots were 

 fed the same ration, the test proper began August 22 and lasted 55 

 days. Lot 1 was fed meal (wheat and barley 1:1) mixed with water, 

 lot 2 meal mixed with sweet whey, and lot 3 meal mixed with sour 

 whey. At the beginning of the experiment proper the weights of the 

 lots were 361.5 lbs., 365 lbs., and 381.5 lbs., respectively. The average 

 daily gains per pig for the 3 lots were 1.23 lbs., 1.64 lbs., and 1.61 lbs. 

 Lot 1 consumed 4.97 lbs. of meal per pound of gain, lot 2 3.72 lbs. of 

 meal and 9.41 lbs. of sweet whey, and lot 3 3.8 lbs. of meal and 8.68 

 lbs. of sour whey. 



Tbe second test was begun with 3 lots of 3 pigs each, but 1 pig was 

 dropped from lots 1 and 2 before the close of tbe test. The conditions 

 of the second trial were the same as in the first. The experiment 

 proper covered 42 days At the beginning of tbe- test proper lot 1 

 weighed 320 lbs., lot 2 341.5 lbs., and lot 3 476 lbs. Tbe average daily 

 gains per pig made by the 3 lots were 1.63 lbs., 1.88 lbs., and 1.95 lbs., 

 respectively. Lot 1 consumed 4.9 lbs. of meal per pound of gain, lot 

 2 3.9 lbs. of meal and 7.79 lbs. of sweet whey, and lot 3 3.85 lbs. of meal 

 and 7.69 lbs. of sour whey. 



In tbe author's opinion the results of the 2 tests indicate tbat sour 

 whey has practically the same feeding value as sweet whey. The 

 experiments will be continued. 



Experiments with different breeds of hogs under different 

 methods of treatment, G. E. Day (Ontario Ayr. Col. and Expt. Farm 

 Rpt. 1896, pp. 71-78). — A test covering 2 periods was made with 36 

 pure-bred pigs divided into 3 lots. Each lot contained 2 pigs of each 

 of the following breeds: Berkshire, Poland-China, Yorkshire, Chester 

 White, Tarn worth, and Duroc- Jersey. Tbe pigs were about 3 months 

 old at the beginning of the trial. The first period began June 18 and 

 continued 1 month. In lot 1 the pigs of each breed were fed in sepa- 

 rate pens 3 times a day all they would eat of meal of different sorts. 

 Lots 2 and 3 were each turned into a clover pasture of about one third 

 of an acre, lot 2 receiving in addition one-half and lot 3 one-fourth the 

 grain ration fed to lot 1. 



The second period, which immediately followed tbe first, covered 3 

 months. Lots 1 and 3 were fed under the same conditions as lot 1 

 daring the first period. Lot 2 was given the run of the 2 pastures and 

 fed a full grain ration. Tbe average cost of the different meals fed was 

 assumed to be $14 per ton. 



During tbe first period the average gain of the pigs in lot 1 was 17.54 

 lbs., of lot 2 5.79 lbs., and of lot 3 2.47 lbs. During the second period 

 the average gain per pig for the different lots was 87.96 lbs., 109.46 lbs., 

 and 98.83 lbs., respectively. Tbe cost of the meal eaten per pound of 

 gain by the different lots during both periods was 3.00 cts., 3 cts., and 

 2.84 cts., respectively. During the second period lot 2, on pasture and
