offset care, skim milk was found to l>o worth 18 cts. (fed in small quantities), 12cts. 

 (fed in large quantities), and 15 cts. (average), while whey proved to be worth 11 cts.

Experiments in the fattening of swine, W. Haunders (Canada 

 TSxpt. Farms Epts. 1896, pp. 84-89). — In continuation of previous work 1 

 tests were made with 10 lots of 3 to 5 crossbred pigs to compare the 

 value of a number of feeding si nil's. The feeding- periods were from 12 

 to 20 weeks' duration. Sunflower heads and grain were compared with 

 2 lots, pulped raw potatoes and cooked potatoes with 5 lots, and ground 

 oats and peas and a mixture of the two with 3 lots. In every case 

 skim milk and mixed grain were fed also. The grain in weight made 

 by the different lots and the shrinkage of the carcass on slaughtering 

 are recorded in tabular form. 



In the comparison of grain and sunflower heads lot 1, consisting of 

 5 pigs, was fed for 18 weeks grain ad libitum soaked in water for 30 

 hours and lbs. of skim milk per head daily. Lot 2, consisting of 5 

 pigs, was fed for the same length of time half as much grain, sunflower 

 heads ad libitum, and (! lbs. of skim milk per head daily. The 

 grain consisted of a mixture of ground barley, rye, wheat, and bran. 

 The following table gives the results of the comparison of sunflower 

 heads and grain :

No general deductions are drawn from the experiments. 



The value of dairy by-products in pig feeding, F. B. Linfield 

 (Clali >St<(. Bpt. J8'.)7, pp. 59, 60). — A preliminary report is given of a 

 test of the value of skim milk, made with 3 lots of 3 pigs each. Lot 1 

 was fed skim milk and chopped wheat, 5 : 1, until the pigs averaged 75 

 lbs., and then in the proportion of 3 : 1; lot 2, skim milk ad libitum; 

 and lot 3, chopped wheat mixed with water ad libitum. The milk was 

 fed fresh or sour. Lots 1 and 2 received some whey with the skim 

 milk. 



The test began January 10 and covered 100 days. The food con- 

 sumed and the gains made are reported and the value of the foods is 

 discussed, reckoning the gain in weight at 3 cts. and at 4 cts. per pound. 



"The gain per day for each hog fed on milk and grain was 2.54 times 

 greater than for those fed on milk alone, and 1.7 times greater than
