lbs., respectively. During the preliminary period of 7 days the aver- 

 age daily gain per pig for the three lots was 1.24, 1.29, and 1.52 lbs. 

 During the experiment proper (29 days) the average daily gain per pig 

 for the three lots was 1.38, 1.26, and 1.35 lbs. Lot 1 consumed 3.36 lbs. 

 of grain and 6.17 lbs. of whey per pound of gain ; lot 2, 3.70 lbs. of grain 

 and 6.79 lbs. of whey; and lot 3, 4.28 lbs. of grain per pound of gain. 



The second test was begun with three lots of 3 pigs under the same 

 conditions as the hrst. However, it was necessary t»> drop lot 1 before 

 the close of the test. Lot 2 (fed sour whey and grain) weighed 230 lbs. 

 at the beginning of the test and made an average daily gain per head 

 of 1.26 lbs. during the preliminary period of 14 days. Lot 3 (fed grain 

 and water) weighed 22V lbs. at the beginning and during the 14 days 

 made an average daily gain of 1.31 lbs. During the experiment proper, 

 which eontinued 64 days, lot 2 made an average daily gain of 1.36 lbs., 

 consuming 3.48 lbs. of grain and 6.96 lbs. of whey per pound of gain. 

 During the same period lot 3 made a daily average gain of 1.41 lbs. 

 and consumed 4.18 lbs. of grain per pound of gain. 



The third test was made with the same number of pigs and under the 

 same conditions as the first. The three lots weighed 290, 295, and 289 

 lbs. and during the preliminary period of 10 days made an average 

 daily gain of 1.76, 1.50, and 1.70 lbs. During the experiment proper, 

 which covered 31 days, lot 1 made an average daily gain of 1.87 lbs., 

 consuming 3.54 lbs. of grain and 6.09 lbs. of whey per pound of gain. 

 The corresponding figures for lot 2 are 1.96 lbs. gain and 3.37 lbs. grain 

 and 5.79 lbs. whey; aud for lot 3, 2.07 lbs. gain and 3.91 lbs. grain per 

 pound of gain. 



The pigs were sold and the meat judged by an expert. No bad 

 effects attended the use of whey. Somewhat better gains were made 

 on sour whey than on sweet whey. 



Comparison of different breeds of swine, Gr. E. Day (Ontario 

 Agr. Col. and Expt. Farm Bpt. 1897, pp. 88-00). — In continuation of 

 work previously reported (E. S. R., 9, p. 478) a test was made with 6 

 lots of 6 pigs each to compare the following breeds: Improved York- 

 shire, Chester-White, Duroc-Jersey, Tamworth, Poland-China, and 

 Berkshire. But one breed was represented in each lot. A record was 

 kept of the food consumed and the gains made by the different lots 

 between the ages of 90 and 180 days. All the pigs were fed grain of 

 some sort, but detailed statements as to the feeding stuffs used and 

 the methods of feeding are not given.
