.ind shorts, equal parts, was better than corn alone, but not equal to the above 

 mentioned rations. Blatchford's pig meal and corn (1:2) was not as effi- 

 cient as corn and skim milk (1:4). Skim milk was not so good as well-bal- 

 anced grain rations with pigs on rape. The rape pasture was superior to the 

 blue grass. 



Digestion experiments with pigs, with special reference to the influence 

 of one feed upon another, and to the individuality of pigs, H. S. Gbindlbtt, 

 W. J. Caemichael, and C. I. Newlin {Illinois Sta. Bui. 200, ahs. {1911), pp.

Mesquite beans for pig feeding {New Mexico Sta. Rpt. 1911, pp. 77-82, fig. 

 1). — Attention is called to the possibility of the greater utilization of the 

 mesquite bean as a stock feed. The pods are sweet, and horses and cattle eat 

 them eagerly. They should not be fed alone as they are constipating, but with 

 wheat bran, alfalfa hay, or a succulent feed. They were not so well relished 

 by pigs, but they were readily eaten when ground and mixed with milo maize 

 meal, 2 : 1. With the milo maize worth $1.50 per hundredweight, the ground 

 beans are worth about 80 cts. per hundredweight. 



In a second experiment two lots of four pigs each were fed for 76 days on 

 alfalfa hay and concentrates as follows : Lot 1, ground corn and ground mes- 

 quite beans, 1:1; lot 2, ground corn alone. During the first nine weeks the 

 ground mesquite beans were about 75 per cent as efficient as gi'ound corn. They 

 were more efficient in the first period of the experiment than in the latter. 



The results of the two experiments indicate that mesquite beans make an 

 economical feed when grains are high. The digging up of the bushes should 

 be discouraged unless a more valuable plant is available that will thrive xmder 

 similar conditions. 



Tankage for pigs (New Mexico Sta. Rpt. 1917, pp. 75-77). — Three lots of 

 12 pigs each, averaging about 60 lbs., were fed ground com, ground corn and 

 packing-house tankage, and ground corn and El Paso tankage. The standard or 

 packing-house tankage contained 62.9 per cent protein and cost $3.60 per hun- 

 dredweight, and the El Paso tankage, a local product, contained 47.7 per cent 

 protein and cost $2.50 per hundredweight. The tankage-fed pigs received 15 

 per cent of the concentrate as tankage until they averaged 100 lbs. each and 

 after that 10 per cent The three lots were supplied at all times with alfalfa 

 hay. 



The cost per pound of gain of the com fed lot was 11.34 cts., of the standard- 

 tankage lot 8.76 cts., and of the El Paso-tankage lot 8.56 cts. The lots on 

 tankage ate more with a better appetite and sold for 10 cts. per hundredweight 

 higher on the El Paso market. 



Inheritance investigation in swine (Kansas Sta. Rpt. 1916, p. 19). — The 

 results of one year's work in swine inheritance indicate that the short dish- 

 face of the Berkshire is transmitted as a dominant sex-linked characteristic. 

 Statistical studies demonstrated (1) that the number of pigs per litter is not 

 correlated with any of the characteristics of form which are commonly sup- 

 posed to influence it; (2) that selection of dams and sires on the basis of the 

 size of the litter in which they are farrowed has no effect on the immediate 

 progeny nor on the second generation; and (3) that the method of fertility 

 inheritance is extremely obscure. 



Horses, E. S. Abchibald et al. {Canada Expt. Farms Rpts. 1916, pp. 506- 

 531, pis. 6). — Experimental work with horses at the different stations dealt 

 largely with the cost of rearing and keeping. 



At Charlottetown, P. E. I., two colts foaled in June and July were weaned 

 October 30. During this time they received some feed in addition to their 

 mothers' milk. From November 1 to March 31 they were fed hay, roots, and
