The determination of the percentage of hull in bai'ley, G. Kamnitz ( Trudy 

 Bitiro Prlkl. Bot. {Bui. Angciv. Bot.), 3 {li)10), .To. 5, pp. 1S3-20S, figs. 2).— 

 This article describes and compares different methods in use for the determina- 

 tion of the percentage of hull in barley. 



The hardness of the seed coat in clover, W. Romanowskij-Romanjko 

 (Trudy Brnro Prlkl. Bot. {Bui. Angew. Bot.), 4 {1911), No. 5, pp. 179-196, 

 figs. 2). — The significance of the hardness of the seed coat in clover is discussed 

 and the results of observations made are reported. 



It was found in general that the clover seed thrashed and stored in the 

 ordinary way had a much higher percentage of germination than seeds retained 

 in the heads several months after maturity. The author observed that the 

 removal of the seed from the head causes softeniug of the seed coat, while its 

 hardness is retained as long as the seed is in an uuthrashed condition. 



Winter emmer, M. A. Cableton {U. 8. Dept. Agr., Farmers'' Bui. Jf66, pp. 24, 

 figs. S). — Discussions of the nomenclature, characteristics, distribution, cultiva- 

 tion, and uses of emmer accompany statements of the results of tests of its 

 adaptation to conditions in the United States. 



During the period 1905-1909 the average yield of winter emmer at MePherson, 

 Kans., was 45.47 bu. per acre. Duriug 1906-1908 the winter emmer G. I. No. 

 2337 produced an average yield of 32.54 bu. per acre at Amarillo, Tex., and 

 during the 2 seasons 1907-1908 G. I. No. 2483 averaged 33.83 bu. per acre. 



At Channing, Tex., G. I. No. 2337 averaged 39.1 bu. per acre duriug 1905 and 

 1906. Trials by farmers in various portions of the United States and the 

 results of cooperative tests of black winter emmer in California are also 

 reported. 



At Worland, Wyo., 2 qt. of black winter emmer were sown in 1907. Only 72 

 plants survived in the spring of 1908 but among these were a few apparently 

 of a different type with large coarse-growing straw and large composite heads 

 of a dark color. These plants were used as the basis of an improved strain 

 which has apparently not winterkilled at all since 1908. In 1908 four-fifths of 

 an acre planted to this strain in rows 2i ft. apart yielded 34 bu. of seed per 

 acre. Sown at the rate of from 30 to 34 lbs. per acre and left without further 

 water for 26 days after the third irrigation it yielded at the rate of 69.1 bu. 

 per acre. 



Numerous tables present other data for the most part already noted from 

 other sources. 



Growing' and using mangels, sugar mangels, and forage sugar beets with 

 notes on their chemical composition, J. H. Grisdale and F. T. Shutt {Canada 

 Cent. Expt. Farm Bui. 67, pp. 20, pis. 5, figs. 7). — Directions for producing 

 and utilizing mangels, sugar mangels, and forage sugar beets are followed by 

 tables presenting analyses of the dry matter and sugar in the juice of varieties 

 grown in Canada during the period 1900-1909, and other data. Duriug 1900- 

 1909 Gate Post and Giant Yellow Globe mangels averaged 12.14 and 10.14 per 

 cent dry matter respectively and 6.69 and 5.00 per cent sugar in juices. 



Peanut culture in Kamerun {Tropenpfianzer, 15 {1911), No. 9, pp. 503, 

 504)- — Together with a general discussion of peanut culture in Kamerun, the 

 results of analyses of 26 different varieties of this crop are reported. The data 

 given include moisture, fat, and protein content. In fat content the different 

 varieties range from 8.5 to 65.74 per cent. All the varieties in question appear 

 to be of African origin. 



On the cultivation in Uruguay of Lolium temulentum ceptochoeton, T. 

 Alvarez {Abs. in Inteniat. Inst. Agr. [Rome], Bui. Bur. Agr. Intel, and Plant 

 Diseases, 1910, Nov., pp. 59, 60). — An analysis of this vai'iety of Lolium temul- 

 entum, made at the experiment station of Toledo, Uruguay, is presented. It is
