department as regards veterinary inspection of ports, importation of animals, 

 registration of pedigree stock, and the federal stock-breeding stations are 

 described. 



Nutritive ratios for growing cattle, A. Goltin and P. Andouard (Bid. Sta. 

 Agron. Loire-Inf., 1912-13, pp. 35-40). — A discussion of the WolfE-Lehmann and 

 the Kellner tables, together with a summary of digestion experiments with 

 young cattle. For maintenance requirements it is stated that 60 gm. of pro- 

 tein per 100 kg. of live weight is necessary, and in additon about 180 gm. of 

 protein for each kilogram of gain in weight. In general a ration which con- 

 tains 1 part of crude protein to 4 parts of nonnitrogenous elements seems to 

 meet the requirements during active growth. 



Changes in the blood of cattle due to the method of slaughter, G. Squadriih 

 (Mod. Zooiatro, Parte Sci., 26 (1915), No. 2, pp. 51-56). — In experiments to 

 determine the effect which the different methods of slaughter have upon the 

 alteration of the blood of cattle, it was found that in shooting the coagulation 

 of the blood is almost instantaneous, the rapidity being greater the less the 

 time elapsing between shooting and bleeding. If the time between death and 

 bleeding was as much as three or four minutes coagulation was delayed. The 

 amount of fibrin in the blood was unchanged but the fibrin appeared to be 

 not entirely normal. The other methods of slaugliter tested had no abnormal 

 effect upon the coagulation of the blood. 



Features of the sheep industries of United States, New Zealand, and 

 Australia compared, F. R. M.\rshall (U. S. Dcpt. Agr. Bui. SIS (1915), pp. 

 35, pis. 8). — The items discussed in this bulletin are the general conditions of 

 sheep husbandry in New Zealand and Australia, the tenure of pastoral lands 

 in these countries, flock management, breeds and types of sheep, shearing and 

 wool classifying, expense of preparing wool for market, selling graded or 

 classed wools in the United States, cooperative .shearing sheds in New Zealand, 

 education of wool growers and their employees, sheep raisers' organizations, 

 and the probable extent of future importations of mutton and wool from 

 Australasia. 



The caracul sheep, the producer of " Persian lamb " and other furs of 

 ovine origin, R. Wallace (Abs. in Froc. Intermit. Cong. Trop. Agr., S (19H), 

 pp. 265-270). — A discussion of the breed characteristics and of experiments in 

 crossing this breed of sheep. 



Difference in weight between raw and clean wools. W. S. I^kwis (Chrm. 

 Engin., 22 (1915), No. 5, pp. 197, 198). — A number of fleeces carefully sampled 

 and thoroughly cleansed of all grease and dirt showed average shrinkages of 

 from 19.5 to 54 per cent, according to the breed of sljeep. 



In the South Australian wools the greatest .shrinkage difference between two 

 determinations upon samples drawn in the same manner from the same fleece 

 was 3 per cent, while for the New Zealand wools the largest difference was 6 

 per cent. The.se differences were calculated on the basis of raw-wool weight. 



The difference in shrinkage between two fleeces of the same bree^l of sheep 

 grown in the same location was found to be as great as 9.5 per cent. The 

 results of such tests upon 13 different breeds of sheep showed a mean varia- 

 tion of 4.5 per cent in the shrinkage. 



Ancestry of the goat (.Jour. Heredity. 6 (1915). No. 11, pp. 519-524. figs. S). — 

 A general r#sum6 of the ancestry and later development of the goat, showing 

 that modern breeds aie all descendants of a single .species. Breeding work has 

 been along two general directions, to improve the yield of milk and to improve 

 the yield of hair, considerable success having been attained along these lines.
