Breeding- mink for tHeir fur, G. F. Noeton {'New York, 19 IS, pp. 22, pi. 1, 

 figs. 6). — This booklet contains directions for the breeding, feeding, care, and 

 management of mink for fur purposes. 



Canadian live-fox shipments, G. C. Woodward and E. J. White {Daily 

 Cons, and Trade Rpts. [U. 8.], 16 {1913), No. 200, p. 1158).— A report of the

DAIRY FARMING— DAIRYING. 



Report of the dairy and cold storage commissioner, J. A. Rtjddick et al. 

 dipt. Dairy and Cold Storage Comr. Canada, 1911, pp. 142, pis. 14). — This 

 report includes items on the following subjects : The outlook for dairying in 

 Canada ; progress report on experiments in the care of hand separator cream ; 

 casein manufacture ; cow-testing associations in Canada ; reasons for cow 

 testing ; export trade of butter and cheese ; and data on the average temperature 

 of creamery butter at Canadian shipping points. 



Report of the dairy experiment station of the Province of Posen for 1912- 

 13, H. TiEMANN, H. Herramhoff and H. Kirsch {Ber. Vers. Stat. u. Lehranst. 

 MoUcw. Wreschcn, 1912-13, pp. 16). — The principal feature of this report is a 

 comparison of the specific weights of the milk and serum and the fat content of 

 the milk for the different months of the year. In these tests the specific weight 

 was lowest in June and highest in January. The fat content was lowest in 

 June and highest in November. 



Milk records, E. Mathews {Jour. Roy. Agr. Soc. England, 75 {1912), pp. 

 9-25). — This article is an account of government milk testing systems in opera- 

 tion in England, Friesland, Denmark, Germany, Ayrshire, Canada, Australia, 

 and Ireland and a discussion of the rules and regulations that should accom- 

 pany such systems. 



• Can a dairy cow be judged by a 2-year-old record, C. H. Eckles {Hoard's 

 Dairyman, 46 {1913), No. 1, p. 6). — The author made a study of the milk fat 

 records of 76 cows, grouping them according to their 2-year-old records, and 

 noting the relation that exists between the yields at this time and those of 

 from 2 to 5 lactation periods later. 



There is evidently a direct relation, for the cows low in milk fat yield as 

 2-year-olds held a similar position at later dates, and the same was true for 

 the medium and high producers. There was no wide variation, however, within 

 the several groups, the cows as a rule coming fairly close to the general average. 

 It is stated that " on the average a dairy cow as a 2-year-old may be expected 

 to produce about 70 per cent, as a 3-year-old around SO per cent, and as a 

 4-year-old around 90 per cent of the milk and butter fat she will produce under 

 the same treatment when mature." 



Importance of the sire in breeding for body weight and milk production, 

 R. G. Bruchholz {Sachs. Landw. Ztschr., 61 {1913), No. 26, pp. 363-366).— The 

 author discusses wherein immediate ancestry affects the body weight and milk 

 production of cows, and gives tables showing the results of studies of the herd 

 book x-ecords of a large number of animals. 



Cost of milk production, A. Manning and H. H. Jones {N. Y. Dept. Agr. 

 Bui. 35, 1912. pp. 1043-1052). — These are general articles dealing with the cost 

 of milk production under New York conditions. 



The composition of milk, H. D. Richmond {Analyst, 38 {1913), No. 44~, PP- 

 252-255). — A report of analyses of 11,677 samples of milk in 1912, in which 

 the morning milk had an average specific gravity of 1.0321, 12.37 per cent of 

 total solids, and 3.51 per cent of fat. The corresponding values for evening
