history, characteristics, and value for agriculture of the vicuiia, which has 

 previously, in the opinion of the author, been underestimated. 



Experiments in swine feeding, G. E. Day {Ann. Rpt. Ontario Agr. Col. and 

 Expt. Farm, 31 {1911), p. 150). — ^A brief report of progress in swine feeding 

 tests. 



Skim milk at 20 cts. per hundredweight proved a cheaper source of protein 

 than oil cake at $36 per ton, but in the absence of skim milk the latter may 

 constitute 10 per cent of the total meal ration. The use of low-grade flours 

 for pig feeding was unprofitable. The amount of water supplied to pigs is 

 thought to be an important factor in growth. The best results were obtained 

 by mixing the meal with enough water to make a thick slop. 



Horses and practical horse keeping, F. T. Barton {London [1912], pp. 

 6.'/3, j^ls. .'(7, figs. 23). — A practical handbook on the horse dealing with breeds,

The horse and its relatives, R. Lydekker {London, 1912, pp. XII +286, i)ls. 

 24, figs. 11). — ^An account of the natural history of the horse, mule, ass, kiang, 

 and zebra, and their extinct forerunners. The work was written for breeders,

Horse breeding {London: Board of Agriculture and Fisheries, 1912, pp.

A history of the Arabian horse and its influence on modern breeds, 

 F. Knorr {Amer. Breeders Mag., 3 {1912), No. 3, pp. 174-180, figs. 3).^A brief 

 historical survey. 



The evolution of a type of horse, W. S. Anderson {Amer. Breeders Mag., 

 3 {1912), No. 3, pp. 209-216, figs. 2). — A discussion of how a type of saddle.horse 

 has been developed by the elimination of undesirable unit characters. The 

 following working hypothesis is suggested : 



" The unit characters of the horse may, in a tentative way, be stated to be as 

 follows: That the finer qualities are recessive to the coarse ones; as the thin, 

 pointed ear is recessive to the heavy thick one ; the clean, small head recessive 

 to its opposite ; the short neck recessive to the long one ; the flat foot recessive 

 to the ' mule ' foot ; the calf knee dominant to the straight, perfect knee ; 

 strength dominant to weakness; true action and superior action recessive to 

 untrue and inferior action. In color, chestnut is recessive to gray, bay, and 

 black." 



Mendelian experinaents with Thoroughbred horses, C. C. Hurst {Blood- 

 stock Breeders' Rev., 1 {1912), No. 2. pp. 86-90). — An outline of an experiment 

 recently undertaken to produce from Thoroughbreds a race of steeplechasers 

 which will breed true. 



The other side of the question {Bloodstock Breeders' Rev., 1 {1912), No. 2, 

 pp. 90-92). — ^A criticism of the above, mainly on the ground that there is no 

 such thing as a Mendelian factor for jumping. 



The figure fallacy {Bloodstock Breeders' Rev., 1 {1912), No. 1, pp. 37-40).— 

 The weak points in breeding horses by the Bruce-Lowe figure system are 

 pointed out. 



Tests of grain and hay for work horses, H. J. Waters {Breeder's Oaz., 61 

 {1912), No. 13, pp. 763, 764, fiff- i).— These tests were made with arrillery 

 horses at the Fort Riley military reservation. There were 10 lots with about 

 75 in each lot, and 7 lots containing from 17 to 20 horses each. Most of the 

 experiments lasted from 110 to 140 days each. 



The cheapest ration, and the one which gave the largest gains, consisted 

 of S lbs. of corn, 2 lbs. of oats, and 10 lbs. of alfalfa hay, and cost 13 cts. per
