274 EXPERIMENT STATION EECOED. [Vol.38 



The leading factors favorable to sheep ruisiug in the State are pointed out. 

 The principal drawback is the danger from sheep-killing dogs. 



Supplements to corn for fattening swine, W. L. Robison {ilo. Bui. Ohio 

 Sta., 2 {1911), No. 10, pp. 317-322, figs. 5).— While corn growing and pork 

 production are closely related industries, attention is called to the fact that, 

 for the best returns in feeding, corn must be supplemented with feeds that 

 make up its deficiencies ; namely, protein and mineral matter. Experiments 

 are reported in which the supplements to corn used were skim milk, tankage, 

 linseed meal, and soy beans. 



In an experiment lasting 70 days with three lots of pigs averaging about 60 

 lbs. each the following gains are reported : With corn and tankage, 9 : 1, the 

 average daily gains per head were 0.S3 lb. and the profit above the cost of 

 feed $4.34; with corn and skim milk, 1 : 1, a daily gain of 1.18 lbs. and a 

 profit of $14.28 ; and with corn and skim milk, 1 : 3, a daily gain of 1.0^4 lbs. 

 with a profit of $10.23. 



In another experiment lasting 105 days with 79-lb. pigs, the lot fed corn 

 alone made an- average daily gain per head of 0.881 lb. with a profit of $3.36 ; 

 the lot fed corn and tankage, 9:1, an average daily gain of 1.709 lbs. with a 

 profit of $28.31 ; while the third lot fed corn and skim milk, 1 : 1, averaged 

 1.635 lbs. daily with a profit of $26.99. 



In a third experiment lasting 105 days with 43-lb. pigs the lot fed com alone 

 made an average daily gain of 0.35 lb. and lost $10.21 ; those on corn and 

 tankage, 9: 1, a gain of 0.899 lb. daily and a profit of $12.38; those on corn and 

 skim milk, 1 : 1, a gain of 0.956 lb. daily and a profit of $14.50 ; and those on 

 corn and skim milk, 1 : 3, a gain of 1.328 lbs. daily and a profit of $22.07. 



Based on two pigs in each lot, the dressing percentages with the lot receiv- 

 ing tankage were such as to make them worth 2 per cent more than the 

 corn-alone lot, and those with skim milk in the ration 3.7 per cent more. 



In an experiment with 145-lb. pigs fed for 84 days the following results 

 were noted : With corn alone the pigs made an average daily gain of 1.47 lbs. 

 per head and a profit of $10.62 ; with corn and tankage, 9 : 1, an average daily 

 gain of 2 lbs. and a profit of $22.72 ; with corn and linseed meal, 5:1, an 

 average daily gain of 1.85 lbs. and a profit of $19.64; and with corn and 

 ground soy beans, 5:1, an average daily gain of 1.62 lbs. and a profit of $15.60. 



The above results were obtained with the feeds valued as follows: Corn, 

 $1.68 per bushel ; tankage, $80 per ton ; skim milk, $10 per ton ; soy beans and 

 linseed meal, $65 per ton ; and hogs, $15 per 100 lbs. 



It is pointed out that in selecting supplements to feed with corn the prices 

 of the materials should have due consideration ; also other factors such as 

 the age of the pigs. Skim milk, for example, gives higher returns with young 

 pigs than with older ones. 



The disposal of city garbage by feeding to hogs, F. G. Ashbrook and J. D. 

 Bebout (17. S. Dept. Agr., Office Sec. Circ. 80 (1911), pp. 8, pi. i).— The Depart- 

 ment is making a study of the handling of garbage, with the object of reducing 

 the cost of handling and utilizing a waste product as a productive material. 

 From the statistics of 17 cities it was found that in seven feeding their garbage 

 to hogs the annual cost per capita was 11.6 cts., while in 10 disposing of it by 

 other methods the cost was 33.7 cts. 



The equipment for a garbage-feeding plant for hogs is shown and described. 

 The collection and handling of garbage, the feeding and breeding of hogs using 

 garbage, and the character of the meat are discussed. 



The horse: His breeding, care, and treatment in health and disease, H. C. 

 Meewin {Chicago: A. C. McClurg & Co., 1911, pp. XIV +281, pis. 13).— A prac- 

 tical treatise on the breeding, care, and training of the horse, and a descrip-
