" T'nder the conditions of the experiment, the i)rofit to I)e derived from short 

 feeding cattle was 7.36 per cent interest on the total expenditure for !K) days 

 for lot 1 and 18.88 per cent for lot 2. With expenses as figured the necessary 

 margin per hundredweight between buying and selling price in Chicago in order 

 to break even was $1,137 for lot 1 (common method of feeding) and $1.16G for 

 lot 2 (chopped hay and self-feeder), when the pork produced is not consid- 

 ered. . , . The larger gain of lot 2 resulted in better finish, 15 cts. per hundred- 

 weight higher selling price, and $2.05 per steer more profit (not including pigs) 

 than lot 1."

 German colonies in Africa and the East Indies.

 pis. 68, tiKip 1). — An account of methods of cattle raising as practiced in south- 

 ern India, including feeding, breeding, and religious ceremonies connected with

The cattle of southern India, W. D. Gunn (Plidippinc Agr. Rev. [English 

 Ed.], 2 (1009), lYo. 12, pp. 6<S5-702, map i).— Extracts from the work noted 

 above. 



The determination of the age of calves, A. Schultze (Die Altersbcstim- 

 miing hvi Kalhcni. Iiiaug. Diss., Univ. Bern, 1909, pp. 52. pis. 3). — The author 

 reviews the literature on this subject and describes in detail the condition of 

 tlie teeth, gums, navel, hoofs, and undeveloped horns in 149 calves. These 

 characters vary so much that no one character is a reliable guide, but it is 

 thought that, taken collectively, one can estimate by means of them the age of 

 the calf witli a reasonable degree of accuracy. 



Farmers' sheep, 11. W. Peacock (Dcpt. Agr. N. S. Wales, Farmers^ Bui. 1, 

 pp. Jf6, figs. 31). — This gives data for the practical farmer, for the most part 

 previously noted from other sources. 



Suggestions for pig feeders (Jour. Bd. Agr. [London], 16 (1909), No. 9, 

 pp. llS-131 ; 16 (1910). No. 10, pp. 820-837).— This is a summary of information 

 of value from a practical standpoint and includes the results of numerous 

 experiments in feeding swine which have been made in Europe and America. 



The brood sow and her litter, F. G. King (Missouri Bd. Agr. Mo. Bui., 7 

 (1909), No. 10, pp. 26). — This is a bulletin of practical information based upon 

 experiments that have been made at the different experiment stations and the 

 practice of the leading breeders and farmers of Missouri. 



Relative efficiency of different rations for fleshing horses for market, R. C. 

 Obrecht (Illinois »S7«. Bui. I'/l, pp. 525-562, figs. 11). — The plan of the first 

 experiment reported was to compare corn with a mixed ration of corn and 

 oats, and clover hay with timothy hay as rations for fleshing horses for mar- 

 ket in an 84-day period. If the preliminary feeding period had been included 

 the entire period would have almost equaled the usual time (100 to 120 days) 

 required to put thin liorses into marketable condition. 



Five mares and 13 geldings from 4 to 7 years of age, weighing about 1,400 

 lbs., were used for this ex!)eriment. The f(»eds were rated as follows: Corn 

 35 cts. per bushel, oats 30 cts. per bushel, bran $20 per ton, old process oil
