DAIRY FARMING DAIRYHSTG. 269 



tail feathers changed in appearance, tlie comb increased in size, the head came 

 to loolv more like that of a cock, and the legs took on the redness characteristic 

 of the male Buff Orpington. She was observed to crow several times; she 

 occasionally visited the nest but never laid an egg. Later she was killed. Dis- 

 section showed no evidence of any development of male reproductive organs, but 

 disclosed a large tumor on the ovary. It is thought that this gi'owth, by in- 

 hibiting the secretions connected with feraaleness, had allowed the male char- 

 acters to become apparent ; for there is reason to believe that every fowl has 

 the potential ability to develop the characters of either sex.

 London: W. B. Saunders Co., 1915, pp. Jfl8, figs. 197). — This book contains chap-

 Bureau, 1915, pp. 119, figs. 38). — A general discussion of methods of breeding, 

 feeding, management, skinning, and marketing of skunks. 



DAIRY FARMING— DAIRYINa. 



[Dairy investigations] (California Sta. Rpt. 1915, pp. 33, 34, 37). — From the 

 results of feeding trials in which barley was the sole concentrate fed, it ap- 

 pears that there is no foundation for the statement often made that barley has 

 an unfavorable influence on the milk secretion and tends to dry up the cows, 

 other tests of feeding barley have been noted (E. S. R., 33, p. 575). 



Data thus far collected show proportionatelj^ less sterility in dairy cattle 

 fed exclusively on alfalfa than in those fed partly on alfalfa or in those 

 receiving no alfalfa at all, thus negativing the popular opinion that alfalfa is 

 the cause of sterility. 



L. M. Davis found that butter made in whole-milk creameries had better 

 keeping quality than that made in the average gathered-cream plant. Pasteuri- 

 zation of old cream did not insure good keeping quality in butter made there- 

 from. The average score of 12 cubes of fresh California June butter, selected 

 from an entry of the Educational Butter Scoring Contest, was 92, After being 

 held 14 weeks it was 88.5, thus showing considerable depreciation during 

 storage. 



Feeding dairy cows in Washington, A. B. Nysteom (Washington Sta. Popu- 

 lar Bui. 92 (1915), pp. 24)- — General directions, on the basis of available data 

 summarized, are given for feeding cows under Washington conditions. 



Milk records in Berks and Bucks, 1913—14, J. Mackintosh (Univ. Col. 

 Reading, Dept. Agr. and Hort. Bui. 25 [191 Jf], pp. 112, pi. 1). — From records kept 

 of the milk yields of 39 herds it appeared that cows calving from August to 

 March may be expected to give from 100 to 150 gal. more milk per annum than 

 those calving in May and June. Cows calving from July to December appar- 

 ently have slightly longer milking periods, the chief reason being the change 

 from winter feeding to the fresh grass of early summer. 



World's champion Red Poll, " Muria," R. R. Kerr (Jour. Dept. Agr. Vic- 

 toria, 13 (1915), Xo. 9, pp. 541-5U, fig. 7).— The Red Poll cow Muria produced 

 in one year 14,972 lbs, of milk containing 884.16 lbs. of milk fat, which is said 

 to be the record production for that breed. 



Milking Shorthorn association formed (Breeder's Gaz., 68 (1915), No. 14, 

 p. 569). — Announcement is made of the formation of the American Milking 

 Shorthorn Breeders' Association, with headquarters at St. Paul, Minn. Ani-
