Seventh annual report of the American Bison Society (Ann. Rpt. Amer. 

 Bison Soc, 7 (1914), pp. 72, figs. 23). — It is said that there has been an increase 

 of 546, or 19 per cent, in the number of buffaloes in North America within the 

 past year, and that owing to the increased interest in this animal its preserva- 

 tion is assured. See also a previous note (E. S. R., 30, p. 469). 



Practical assistance to wool growers in the marketing' of their wool clips 

 (Canada Dept. Agr., Live Stock Branch Pamphlet 7 (191Jt), pp. 18). — General 

 information on the production of wool of good quality and condition, together 

 with suggested plans for use in organizing a wool growers' association, is 

 presented. 



The Grenada goat, L. Gimenez (Indus. Pecuaria, 15 (1914), No. 462, pp. 377, 

 378, figs. 2; abs. in Internat. Inst. Agr. [Rome], Mo. Bui. Agr. Intel, and Plant 

 Diseases, 6 (1915), No. 1, p. 116). — This breed of goats is described as being 

 hornless and of average size. The color is chestnut or b'.ack, and the udder is 

 large and well developed. The she-goats become serviceable at 6 months and 

 may continue to breed to the age of 9 or 10 years. They mostly give birth to 

 twins and sometimes triplets. The yield of milk is generally from 2.6 to 3.5 

 lbs. per day after the first parturition, the quantity increasing v/ith subsequent 

 lactations until the fifth, when it reaches its maximum of from 13.2 to 14.1 lbs. 

 The milk is said to be excellent and without the characteristic odor of that of 

 other breeds of goats. The flesh is also of good quality. 



[Pork production], M. Herter and G. Wilsdorf (Arl). Deut. Landw. Oesell., 

 No. 270 (1914), pp. 1-38, figs. 15). — A discussion of the comparative value of the 

 Berkshire, Yorkshire, and native German breeds of hogs for pork production, 

 and of the methods of swine feeding. 



Swine feeding experiment comparing skim milk with fat-freed fi.sh meal 

 and dried yeast, Klein (Milchw. ZentU., 43 (1914), No. 17, pp. 452-458).— In 

 experiments with young pigs fed a basal ration of potato flakes and barley, it 

 was found that ^ lb. of fat-freed flsh meal or 1 lb. of yeast was equivalent for 

 feeding purposes to 1 gal. of skimmed milk. These feeds, especially the yeast, 

 gave better results with older than with younger pigs. 



The valuation of the manurial residues obtained from the consumption of 

 foods by growing pigs, C. Crowther and A. G. Ruston (Jour. Bd. Agr. [Lon- 

 do7i'i, 21 (1914), No. 9, pp. 789-800). — With a view to determining the manurial 

 A'alue of pig offal, ten 2-nionth-old Yorkshire pigs were fed for 23 weeks on 

 rations composed of bran, middlings, pea meal, and barley meal, and collections 

 and analyses made of the urine and feces. The percentage of the food nitrogen 

 recovered ranged from 44 in the earlier stages to 68 in the later stages, with 

 an average of 56 ; phosphoric acid, 45 to 71 with an average of 58 ; potash from 

 67 to 98 with an average of 87 ; and lime from 30 to 75 with an average of 65. 

 The distribution of the manurial ingredients recovered between solid and liquid 

 excreta was found to be as follows : Nitrogen 35 per cent In the solid, 75 per 

 cent in the liquid; phosphoric acid 77 and 23; potash IS and 82; and lime 92 

 and 8, respectively. These values are lower than those given by Voelcker and 

 Hall (E. S. R., 14, p. 1057). 



Sex-linked factors in the inheritance of rudimentary mammae in swine, 

 E. N. Wentworth (Proc. loica Acad. Sci., 21 (1914), pp. 265-268). — The author 

 presents evidence tending to show that the inheritance of rudimentary mammse 

 in swine is a combination of the sex-linked and sex-limited types. It appears 

 sex-linked in so far as the transmission of the genetic factor for rudimentaries 

 is concerned, and sex-limited in so far as there is apparent repression somatically 

 of the rudimentaries of the female sex when they are in a simplex condition.
