The composition of bran and shorts as milled under the regulations of the 

 Canada Food Board, F. T. Shutt and R. L. Dorrance {Agr. Gaz. Canada, 5 

 (1918), No. 8, pp. 1160-762). — Canadian samples of bran and shorts ccrllected in 

 1903 and 1917 are compared as to proximate composition with samples collected 

 after April 1, 1918, when regulations became effective in Canada requiring a 

 76 instead of the customary 72.5 per cent extraction of spring wheat by millers. 



The 1918 bran showed a lower moisture content and increases of about 0.75 

 in the protein percentage, 0.5 in the fat, and 1.5 in the fiber. The shorts showed 

 decreased moisture, increases of about 1.75 in protein and 2.5 in £ber per- 

 centage, and a decrease in nitrogen-free extract. The 1918 samples were much 

 more uniform in protein, fat, and fiber content than the earlier collections. 



Bange management on the National Forests, J. T. Jardine and M. Anderson 

 (U. S. Dcpt. Agr. Bui. 790' (1919), pp. 98, pis. 32, figs. ^).— The object of this 

 publication is to aid in bringing about uniformity in range management and a 

 better understanding of grazing use in relation to the other uses of the Na- 

 tional Forests. The topics covered include the determination of the classi of 

 stock to which a range is best suited, grazing periods, grazing capacity, man- 

 agement of cattle on the range, management of sheep on the range, range re- 

 seeding, grazing in relation to protection of timber, watersheds, game, and 

 recreational use, and range reconnaissance and inspection. A special bibliog- 

 raphy for each of these topics is added. There are also brief sections on stock 

 driveways and poisonous plants, a bibliography for stock -poisoning plants in 

 the United States, and notes on the collection and identification of forage and 

 range plants. 



Fattening steers on summer pasture in the South, W. F. Ward, D. T. Gray, 

 and E. R. Lloyd (U. S. Dept. Agr. Bui. 777 (1919), pp. 2^, fig. 1).— Steer feeding 

 experiments during the summers of 1912 and 1913 in collaboration with the 

 Alabama College Experiment Station, and during the summers of 1915 and 

 1916 in collaboration with the Mississippi Experiment Station, are reported. 

 They form part of a general cooperative series (E. S. R., 40, p. 873) and fol- 

 low the pasture experiments reported in part 2 of Bulletin 110 (E. S. R., 81, 

 p. 664). 



The experiments were ^designed to compare summer pasture alone with pas- 

 ture plus cottonseed cake. In two of the years a lot was also fed in which 

 half the cake was replaced by corn. The principal pasture grasses were 

 lespedeza, Bermuda grass, and crab grass. The Alabama pastures were seeded 

 with sweet clover, and the 1916 pasture contained abundant white clover. 

 During 1912, 2- and 3-year-old grades of beef breeds of fair quality were fed. 

 In each successive season poorer and more mature cattle seem to have been
