breeding work being done with lougwools and Dorset Horns, and crossbreeding 

 experiments which have been previously noted (E. S. R., 30, p. 372). 



Animal feeding, dairy cattle, milk, butter, beef cattle {Scranton, Pa., pp. 

 IX+[624]+XI-XXIV, figs. 290).— This volume, which is a part of the Inter- 

 national Library of Technology, treats of animal feeding, breeding, and man- 

 agement, and contains chapters on dairy and beef cattle production. 



Studies on the work of protein in the intestinal canal, F. A. Kramm 

 (Stud'ien ilber den Ahbau der Proteine im Dannkanal. Inaug. Diss., Univ. 

 Leipsic, 1912, pp. H). — The author reviews the work of Abderhalden on the 

 work of the protein substances and peptones in the intestinal canal and gives 

 the results of experiments showing the rapid transformation of these substances 

 up to the amino acid stage. 



Studies on the passage of drinking water through the stomach, R. Otto 

 (Studien ilber den Transport getrunlcenen Wasscrs diirch den Magen. Inaug. 

 Diss., Vmv. Leipsic, 1912, pp. 59, pis. 6). — This reports extended studies made 

 of the passage of water through the stomach of the horse and dog. 



[Experiments in animal production] (Xebrasha Sta. Rpt., 1913, pp. XI- 

 XIII). — This is a summarized account of recent experiments in animal pro- 

 duction. 



Six lots of cattle wei-e fed upon corn and the following supplements : Lot 1, 

 prairie hay and cold pressed cotton-seed cake ; lot 2. corn silage and cotton-seed 

 cake ; lot 3, corn silage and prairie hay ; lot 4, a heavy ration of corn silage 

 and alfalfa hay ; lot 5. a light ration of corn silage and alfalfa hay ; and lot 6, 

 alfalfa hay. The respective daily gains per head were 1.92, 2.01, 1.75, 2.24, 2.04, 

 and 2.29 lbs., and the costs per pound of gain 9.53. 9.21, 9.08, 7.76, 8.33, and 7.21 

 cts., respectively. These results do not correspond with those of earlier experi- 

 ments and it is purposed to duplicate the work before final results are pub- 

 lished. 



Four lots of hogs were fed as follows : Lot 1, soaked whole wheat ; lot 2, 

 soaked whole wheat and tankage; lot 3, soaked ground wheat; and lot 4, soaked 

 ground wheat and tankage. Wheat was valued at 75 cts. per bushel and tank- 

 age at $2.50 per hundredweight. The lots of pigs made a total gain of 705, 825, 

 1.000. and 1,108 lbs., respectively, costing 8.40, 6.G, 5.84. and 6.06 cts. per pound 

 of gain. ~ 



Economical cattle feeding in the corn belt, J. S. Cotton and W. F. Ward 



/ (U. S. Dept. Agr., Farmers' Bui. 588 (1914), pp. 19, figs. 6).— The authors dis- 



/ cuss the cost of producing and of feeding cattle, the care of manure and main- 



tenance of soil fertility, methods of cattle feeding adapted to high-priced and 



moderate-priced laud, use of hogs following cattle, shrinkage, etc. 



Cost of beef production under semi-range conditions, G. E. Morton et al. 

 (Colorado 8ta. Bui. 189 (1913), pp. 3-8).— The object of the experiment here 

 reported was to secure information concerning the cost of producing fat 2-year- 

 // old cattle under modified range conditions, the cattle to be run on native grass 

 / within fences in summer and to be winter fed. 

 I / It is estimated that about 20 acres of range is required per head with ordi- 

 1 ' nary weather conditions. Fifteen head of range-bred 3-year-old cows of Here- 

 ford and Shorthorn blood were used in the experiment. These calved in May 

 to July. The 15 calves were brought in on October 20 and winter fed until 

 I June 3. The average gain in weight per head was 339 lbs., or 1.63 lbs. daily 

 l\ gain. The amount of feed consumed per head was 2.200 lbs. alfalfa hay and 

 ' 788 lbs. barley, valued at $13.38, and the cost per pound of gain,^^S5_cts. It 

 is stated that these results encourage the liberal winter feeding of range calves. 



The yearlings were sunnner ranged under adverse conditions, and made only 

 26 lbs. average gain per head. Again they were winter fed, going in September
