876 EXPERIMENT STATION RECORD. 



Plant Diseases, 2 (1911), No. 4, p. 915). — A brief description of this breed, 

 which is common in Austria, Hungary, and the Balkan States. 



Maine experiments with cross-bred poultry, J. H. Robinson (Farm Poultry, 

 22 (1911), Nos. 8, pp. 206-208; 9, pp. 222-22Ji).—A review of worli previously 

 noted (E. S. R.. 23, p. 074). 



On the structure and function of the oviduct of the pigeon, B. Hank6 

 (Allattani Kozlem., 9 (1910), No. 1, pp. 26-^8; abs. in Zentbl. Allg. u. E.cpt. 

 Biol., 2 (1911), No. 7-8, p. 200).— This describes the histology of the oviduct 

 and the physiology of the secretions connected with it. In general there were 

 but slight differences from those previously reported by other observers from 

 studies of the domestic fowl. 



Oviposition induced by the male in pigeons, W. Craig (Jour. Morph., 22 

 (1911), No. 2, pp. 299-305). — It was found that pigeons differ from fowls as 

 the male stimulates the female to lay without copulation. In one case stimu- 

 lation by the hand of man was followed by oviiX)sition. Old females, if kept 

 isolated, refrained from laying. It is concluded that the stimulus to the whole 

 process of egg laying is a psychic stimulant and not dependent upon copulation. 



The hygiene of slaughterhouses. Barrier (Off. Internat. Hyg. Puh. [Paris], 

 Bui. Hens., 3 (1911), No. 3, pp. ^51-467; ahs. in Internat. Inst. Agr. [Rome], 

 Bui. Bur. Agr. Intel, and Plant Disea^-'cs, 2 (1911), No. 5, pp. 1110, 1111). ~A 

 report on the conditions under which licenses are granted to private slaughter- 

 houses. 



DAIRY FARMING— DAIRYING. 



Care and management of the dairy herd, J. C. McNutt (North Carolina 

 Sta. Bui. 220, pp. 73-84, flffs. 9). — A popular bulletin dealing with the selection, 

 feeding, and improvement of dairy cows under North Carolina conditions. The 

 feeding of corn silage and other home-grown feeds is urged. The care and 

 management of the herd bull, raising of dairy calves, and the age to breed 

 heifers are discussed. 



[Report of dairy work], G. H. True (Nevada Sta. Bui. 73^, pp. 36-38).— 

 The yearly records of the cows of the station herd and the best 7-day records 

 are given. In a dairy survey of Douglas County the average production of 

 milk fat in 54 herds was found to be 221.48 lbs. per year, the range being from 

 91.8 to 317.75 lbs. 



A breeder's herd records, G. Harold (Country Gent., 76 (1011), No. 3059, 

 p. 10, figs. 4)- — Illustrations are given of methods of keeping milk and breeding 

 records on a dairy farm. 



Dairying, J. A. Ruddick (Rpt. Dairy and Cold Storage Comr. Canada, 1911, 

 pp. 15-116, pis. 8). — This contains data on exports of dairy products in Canada, 

 milk records of dairy herds, cow-testing associations, and related topics. 



Milk tests (Field Expts. Harper- Adams Agr. Col., and Staffordshire and 

 Shropshire, Rpt. 1910, p. 53). — The average percentage of fat in the milk of 

 the college herd was 3.5 in the morning and 4.04 in the evening milk. The 

 average yield of cheese per gallon of milk was 1.26 lbs. The lowest yield was 

 1.08 lbs., occurring in June, and the highest 1.48 lbs. in February. 



An experimental study of the causes which produce the growth of the 

 mammary gland, R. T. Frank and A. Unger (Proc. N. Y. Path. Soe., n. ser., 

 11 (1911), No. 1-2, pp. 4-8). — To ascertain whether heterologous fetal extracts 

 produced breast hyperplasia, rats were injected with cow's fetuses, rat's fetuses, 

 ovaries, and placentas. Starling's technic was employed, but the results were 

 negative. The same methods were then used with rabbits, using extracts of 

 rabbit's fetuses, ovaries, placentas, and hypophyses. The results varied greatly
