 Victoria, 3 ( 1905), No. 4, pp- -79-329, pis. 12, figs. 8). — This contains an introduction 

 on the selection and preparation of land for a dairy farm and chapters on breeding, 

 feeding, and management of cattle; common ailments of dairy cattle; dairy farm 

 buildings; fodder for the dairy herd; dairy management; and milk testing. 



Farm dairying-, J. C. Kendall (North < 'arolina Sta. Bui. 192, pp. 19-48, figs. 9). — 

 This is a popular bulletin dealing with the various phases of dairying, with special 

 reference to North Carolina conditions. 



External conformation and productive capacity of cattle, H. Attinger 

 ( Beit rage zur Kenntnisvon Korperform und Leistungd.es Rirules. Leipsic: B. C. Schmidt 

 & Co.; rev. in Vrtljschr. Bayer. Landw. Bat., 10 {1905), No. 1, p. 103). — This volume 

 deals especially with the question of the relation between external conformation and 

 productive capacity in milch cows. 



Report of the dairy husbandman, G. A. Billings (New Jersey Sta s. Rpt. 1904, 

 pp. 341-412)- — The first part of this report deals with soiling crops and is abstracted 

 elsewhere (p. 353). 



For 8 years the dairy herd has been fed soiling crops from May 1 to November 1 

 each year and silage for the remaining 6 months. On soiling crops the average pro- 

 duction was 3,322 lbs. of milk and 167 lbs. of butter and on silage 2,997 lbs. of milk 

 and 152.5 lbs. of butter. The cost of the roughage was also in favor of the soiling 

 crops. 



Dried beet pulp was compared with dried molasses beet pulp as regards influence 

 on yield of milk and butter, effect on quality of milk, and relative cost of milk and 

 butter. The test was made with 4 cows and lasted 30 days and indicated that the 

 addition of beet molasses to beet pulp is no advantage in feeding for the production 

 of milk. On the ordinary or unsweetened dried beet pulp the average daily yield 

 of milk was 0.33 lb. and the yield of butter 0.02 lb. greater than on the dried 

 molasses beet pulp. The relative cost of producing 100 lbs. of milk on the 2 rations 

 was, respectively, 67.2 and 69.8 cts. 



A similar comparison was made of dried molasses beet pulp and hominy meal. 

 With rations otherwise alike 8 lbs. of dried molasses beet pulp produced 1.36 lbs. 

 more milk and 0.09 lb. more butter per cow per day than 7 lbs. of hominy meal. 

 The relative cost of producing 100 lbs. of milk on the 2 rations was, respectively, 

 68.9 and 78.1 cts. The hominy meal contained 8.41 per cent crude fat and the dried 

 molasses beet pulp 0.42 per cent, yet the average fat content of the milk was 0.04 per 

 cent higher on the pulp ration. 



The usual monthly record of the dairy herd is given. The average yield for the 

 year was 5,642.2 lbs. of milk or 280.58 lbs. of butter. The best cow produced 8,752.3 

 lbs. of milk and the poorest cow 3,443.9 lbs. The average cost of food per cow per 

 year was §47.12. With milk at $1.00 per 100 lbs., 21 cow\s returned a net profit over 

 cost of food of $22.39 per cow, while 11 cows were kept at a loss of $2.25 per cow. 

 The average cost of producing 1 qt. of milk was 1.83 cts. for food and 1.03 cts. for 

 labor and interest on the capital invested, or a total of 2.86 cts; the average for 8 

 years was 2.43 cts. The record of 1 Guernsey cow entered in the Advanced Register 

 during the year was 8,603.4 lbs. of milk and 369.34 lbs. of fat. 



The usual data are given on the fertilizing elements in the feeding stuffs purchased 

 and the milk sold. The total gain to the farm in 8 years was 11,868 lbs. of nitrogen, 

 8,879 lbs. of phosphoric acid, and 2,836 lbs. of potash. 



The hand separator was compared with the deep-setting system of creaming with- 

 out ice. The average fat content of the separator skim milk for 8 days was 0.022 per 

 cent as compared with 0.95 per cent with the gravity system.
