634 EXPERIMENT STATION RECORD. 



Tte investigation of different breeds of dairy cattle, P. Collier (New York 

 State Sta. Rpt. 1SD4, pp. 0-121). — This is a continnatioa of the investigation ■which. 

 has been in progress for several years, previous accounts of which have been given 

 in the Annual Reports of the station for 1891, 1892, aud 1893 (E. S. R., 4, p. 255; 6, pp. 

 68,1013). The record includes 26 cows of the following breeds : Ayrshire, Jersey, 

 American Holderness, Guernsey, Devon, Holstein-Eriesian, and Shorthorn. The 

 report consists almost entirely of tabulated data, with practically no general discus- 

 sion. The data given include the amount of food fed to each cow during each yieriod 

 of lactation; analyses of the feeding stuffs, i. e., corn silage, mixed hay, corn stover, 

 clover hay, timothy hay, alfalfa forage, oat and pea forage, beets, ground oats, and 

 wheat bran, and several grain mixtures; the food ingredients fed to each cow in 

 each period of lactation ; the composition of the milk by months; the cost of pro- 

 duction of milk and fat for each cow in each period of lactation; sunnuaries as to 

 the yield and composition of milk and the cost of production ; yields of milk in the 

 morning and evening in each period of lactation; the average yield and fat content 

 of milk for each cow in each period of lactation, and the relation of fat in the food 

 to fat in the milk. 



A comparison of these breeds for milk, butter, and cheese production has been 

 given in Bulletins 77, 78, and 79 of the station (E. S. R., 7, pp. 45-47). 



The chemistry of dairying, H. Snydeu (Easton, Pa.: Chemical Publishing Co., 1897, 

 pp. Fill, 156, jj/s. S!, fi(j8. 21). — This is an elementary text-book, intended to furnish 

 "useful information to a class of young men who intend to become farmers and 

 dairymen, rather than scientific experts." The author has made a wise selection of 

 material, which he has presented in an attractive form in plain, concise language. 



Beginning with the composition of milk and the character of the separate ingre- 

 dients, the methods of testing milk are described, the chemistry of butter making 

 and cheese making, and the preservation of milk by sterilizing, pasteurizing, and 

 condensing, are discussed; the composition of skim milk, buttermilk, and whey, 

 and of the milk of other domestic animals, is given, together with the sanitary con- 

 dition of cows' milk, the effect of food upon the quality of dairy products, and the 

 adulteration of dairy products, concluding with a chapter on the composition of 

 fodders and the calculation of rations. At the end of each chapter a considerable 

 number of references are given to books aud bulletins relating to the subjects 

 treated, and in an appendix review questions for classroom use are given. The 

 book has a good index.
