above the seed and near tbe surface of the soil. The seeds planted 10 cm. deep 

 are noted as having three tillers. 



Wheat production in Georgia, J. R. Fain and P. O. Vanattkr (Ga. State 

 Col. Agr. Circ. 6 (lOl.'f), pp. -}). — This circular notes the production of wheat 

 in Georgia. The results of tests from 1909 to 1914 show yields ranging from 

 18.33 to 32.91 bu. per acre with an average of about 25 bu. 



Washington wheats, E. G. Schafeb and E. F. Gainks (Washington Sta. Bui. 

 121 (1915), pp. S-16, figs. 2). — ^This bulletin describes fifteen varieties of wheat 

 grown in Washington, and gives yields of field and nursery tests of numerous 

 varieties for the years 1911. 1912, and 1914. Tables show the percentage of 

 tlour produced and of wet gluten, dry gluten, and nitrogen contained in the 

 wheats studied. 



The best varietj- in the test as to both yield and quality is noted as being 

 Hybrid 12S, a cross between Jones Winter Fife and Little Club. The average 

 yield for this variety for the three yeai-s mentioned was 43.8 bu. per acre. 



Nitrogen content of the wheats of southeastern Russia, N. Tulaikov 

 (luzh. Russ. Sclsk. Khoz. Gaz., No. 9 (1913), p. 6; ahs. in Zhur. Opytn. Agrmt. 

 (Russ. Jour. Expt. Lanclw.), 14 (1913), No. 4, p. 401). — This article gives results 

 of experiments that indicate the influence of the concentration of the soil solu- 

 tions as affecting the nitrogen content of wheat. It is stated that by increasing 

 the soluble salts, but not changing the moisture content in the soil in which 

 the wheat was grown, the nitrogen content of the grain was increased con- 

 siderably. 



A new sterilization stopper and method of storing seeds by the use of 

 wire gauze and cotton, M. Plaut (Ber. Dent. Dot. OeselL, 32 (1914), 'No. 7, 

 pp. 466-471, figs. 3). — A method is described for covering glass bottles or other 

 containers with a layer of cotton under wire gauze to allow for aeration in 

 storing seeds. 



Seed inspection (Maine Sta. Off. Insp., 64 (1914), pp. 153-164).— The chief 

 requirements of the Maine seed-inspection law are given, methods for testing 

 seeds at home are described, and results of seed inspection for 1914 are given 

 in tabular form showing nearly 1,300 samples as being practically up to the 

 guaranty of purity. 



Forty years of seed-control work, M. Heinrich (Landio. Vet's. Stat., 85 

 (1914), No. 3-4, pp. 269-357, pi. i).— This article reviews the work of the seed- 

 control station of Rostock, giving tabulated data and discussions of important 

 species handled since 1874, when 116 seed samples were examined. The number 

 in 1913 reached 3,028. 



Thirty-sixth report of the Swiss Seed Control and Experiment Station at 

 Zurich, F. G. Steblee (Txindw. Jahrb. Schwciz, 28 (1914), ^^o. 2, pp. JS7-209).— 

 This gives the results of seed examinations of 12,702 samples from 199 kinds, 

 and briefly reviews the exiierimental work with field crops. 



Weeds of barley iields in the forest area of European Russia, A. I. Maltskv 

 (Trudy Bfiiro Prikl. Bot. (Bui. Angcw. Bot.), 6 (1913), No. 12, pp. 825-962).— 

 This discusses the immense damages to the barley industry caused by weed 

 seeds, and lists and describes the different weeds of several Governments of 

 European Russia, giving results of analyses of samples that show the per- 

 centage of weed seeds by weight and by number.
