DAIRY FAEMING DAIRYIKG. 773 



Breeding horses for the army, J. E. Downing (Breeder's Gas., 59 (1911), 

 No. 9, pp. 563, 564, fid- i).— An outline of a plan for supplying horses for the 

 service of the United States Army. 



The half-bred horse, A. Gallier (Le Cheval de Demi-Sang. Paris, 1908, pp. 

 VI+332).— This book treats of the origin, characteristics, and uses of cross- 

 bred horses in the diiferent districts of France. 



The encyclopedia of the stable, V. Shaw (London and Netv York, [1910], 

 pp. 363, pis. 15, figs. 102).— "A complete manual of the horse, its breeds, 

 anatomy, physiology, diseases, breeding, breaking, trainmg, and management, 

 with articles on harness, farriery, carriages, etc." 



Heads, combs, wattles, and ear lobes of standard bred fowls, F. L. Sewell 

 (Rel. Poultry Jour., 11 (1910), Nos. 1, pp. 5-'t, 55, 8ft, figs. J,; 2, pp. 171-d73, 

 249-252, figs. 8; 3, i)p. 331-333, 354, 355, figs. 11; 6, pp. 608-610, 628-631, figs. 6; 

 9, pp. 852-855, 893-896, figs. 9).— This article discusses the different types of 

 heads, the correlation between head and comb, and the type of head as an 

 ^index to the type of body. Ideal heads of fowls, defects of the head, and heads 

 of prize-winning birds are illustrated and described. 



A note regarding variation in the single combs of fowls, R. Pearl (Mendel 

 Jour., 1911, No. 2, pp. 189-195). — ^An answer to a criticism of work previously 

 noted (E. S. R., 23, p. 674). 



Construction of a modem poultry house and report of experiments in 

 hopper feeding laying hens, PI. Atwood (West Virginia Sta. Bui. 130, pp. 195- 

 206+7, pis. 3, dgms. 7). — ^A report is given of a trial of the hopper feeding- 

 system for poultry, which was installed in order to save labor. In a year's test 

 with 5 pens of white Leghorns the cost of food varied from 68 cts. to $1.04 per 

 fowl per year, and averaged 90 cts. per fowl for the 100 fowls in the experiment. 

 The egg production varied from 81.4 eggs per hen, when fed principally upon 

 corn, to 124.7 in the pen which received whole grain once per day, scattered 

 in litter, and dry mash and beef scrap ad libitum in a hopper. The food cost 

 of the egg* during the year varied from 8.5 cts. to 11.9 cts. per dozen. Two 

 pens, hopper fed, produced eggs having a lower food cost than the pen which 

 received moistened mash, and iu this test there was apparently no benefit from 

 the extra labor involved in moistening the mash. 



The open-front laying house, previously noted (E. S. R., 19, p. 1172), has 

 continued to give satisfaction in respect to the comfort and health of the fowls, 

 but the double wall on the north side of the house has proved to be an excellent 

 harbor for rats, and the method of construction is not recommended. A new 

 open-front house of another type, 24 by 64 ft., large enough to house 400 Leg- 

 horns and costing $450, is illustrated and described. 



DAIEY FARMING— DAIRYING. 



A dairy laboratory guide, H. E. Ross (Netv York, 1910, pp. VI+84, pi. 

 1). — This is designed as a guide for students engaged in dairy laboratory work, 

 and brief explanations are given with each exercise, although the work is not 

 intended to be used in the place of a general text-book on dairying. The book 

 can also be used by the practical dairyman who wishes to test milk and its 

 products. 



Systems of dairying, W. J. Fraser (Wallaces' Farmer, 36 (1911), No. 12, p. 

 573; Hoard's Dairyman, 42 (1911), No. 13, pp. 450, ^.5i).— Four different sys- 

 tems of dairy farming were compared, producing from 991 lbs. to 3,150 lbs. of 

 milk per acre and returns of from $15.16 to $48.20 per acre.
