iiimieili.ite expenses, alfalfa gi-dwing and dairying, the growing of orchard, 

 small frnit, and vegetable crops, the valne of green^manure and cover crops, 

 and the nsefnlness of wind-breaks, and a list of publications of this Department 

 deemed of service to settlers. 



The search for new leguminous forage crops, C. V. Piper ( U. S. Dept. Agr. 

 Yearbook 1908, pp. 2Ji')-260, pis. 7). — The need for new leguminous forage crops 

 is pointed out, the conditions affecting the search for new species described, 

 and the climatic conditions of different sections of this country with those of 

 other countries are compared. The article contains descriptions of the follow- 

 ing leguminous forage plants and discussions of their economic value: Lyon 

 beau (Stizolohiitin lyoni), kudzu {Pucraria fhunbcrgiaun) . guar {Cyamopsis 

 telragouoJoha), the Tangier pea {Lathijrus fingitaiiiis), Siberian alfalfa (Medi- 

 cago falcata), moth bean (Pfiascolus aconitifolitis), adzuki bean (P. angiilaris), 

 cowpea (Vigiia unguiculata), soy beans (Soja Mspida), Bonavist or hyacinth 

 bean {DoUclws lahJah), kuiti {D. biflorus), bur clovers (Medicago denticiUata 

 and M. arahica), and vetches {Vicia sativa, V. fulgens, V. atropiirpurea, and 

 V. dasycarpa). 



The selection of cotton and corn seed for southern farms, S. A. Knapp ( XJ. 8. 

 Dept. Agr., Bur. Plant Indus. Doc. J/So, pp. 8, figs. 6). — Brief directions are 

 given for the improvement of cotton and corn by seed selection. The matter 

 I>resented is largely taken from publications previously noted (E. S. R., 17, p. 

 548; IS, I). 1120; 19, i)p. 7.34, 836). 



Alfalfa, O. M. Ball (Texas 8ta. Bui. 109,'^ pp. 3-/S).— This bulletin is a gen- 

 eral treatise on the culture of alfalfa in Texas. The results of analyses of 

 alfalfa seeds for 1906 are partially reported and the quantities of weed seeds 

 found in the samples are pointed out. 



New barleys (Wchiischr. Brau., 26 (1909), No. 36, pp. J,29, J,30) .—A tabular 

 description of new varieties of barley from Galicia, Moravia, Russian Poland, 

 Bukowina, Slavonia, Hungary, and Franconia is presented. 



The moisture content of the different varieties varied from 12..50 to 17.76, 

 the protein content in the dry matter from 8.15 to 13.(53, and the quantity of 

 desirable kernels from 28.6 to 94.5 per cent. The barleys from Hungary and 

 Slavonia were in general low in protein and moisture. In the 1,000-kernel 

 weight of air-dry grain, Franconia barleys excelled with weights ranging from 

 45.6 to 48.S gm. 



Some factors involved in successful corn growing, C. B. Williams (North, 

 Carolina Sta. Bui. 20.), pp. ')-.'f2, figs. 22). — This bulletin discusses early, 

 medium, and late maturing varieties of corn, varieties adapted to certain sec- 

 tions of the State, factors affecting the i)eriod of maturity, conti'ollable factors 

 affecting yield, and methods of improvement in general. 



Cowpeas, A. .M. Ten Eyck and L. E. Call (Kansas 8ta. Bnl. 160, pp. 179-209, 

 figs. 10). — The uses of cowpea for hay, soiling, ensilage, pasture, soil im- 

 provement, and green manuring are pointed out and the methods of growing, 

 harvesting, thrashing, and storing the crops are discussed. Experimental 

 results obtained by the station are also reported. 



The average results for 5 years show that corn grown alone from 1903- 

 1907, inclusive, produced 43.98 bu. per acre as compared with 47.62 bu. 



<^ This bulletin must not be confused with the bulletin, also numbered by the 

 station Bulletin 109, entitled The Determination of Cotton-seed Hulls in Cotton- 

 seed Meal, by G. S. Fraps, issued in August, 1908, and previously noted (E. S. R., 

 20, p. 510).
