of the United States, the types of tohawo jirown. and the methods of handling 

 the ci-oiis. 



Bright tobaccos, F. (Miari.an {CinidtJn Dcjil. Am:. Tobdcco Dir. Bui. A7, pp. 

 l.'i). — This bulletin discusses soils, fertilization, cultivation, curing, and market- 

 ing as related to the tobacco industry in southern Virginia and North Carolina. 



Tobacco, F. Charlan (Canada Dcpt. A (jr.. Tobacco Div. Bills. Al, pp. 10; 

 A2, pp. 8; A3, pp. I'f). — In the first of these bulletins general information with 

 regard to the setting up of the forcing bed, germination, sowing, weeding, thin- 

 ning, ventilation, and transplanting of seedlings is given, as well as data as to 

 the diseases and insect pests of (he plant. In the second data are presented on 

 the plant food requirements of the tobacco crop and the essential qualities of 

 smolvlng tobacco, with directions for the proj^er use of manures to secure a crop 

 of good quality. The third bulletin contains notes on the selection, pre])aration 

 and manuring of land for tobacco, sowing, setting out, resetting, cultivation, 

 hilling, thinning, topping, sucliering, harvesting, and the selection of seed plants, 

 directions for curing, stripping, bulking, tying, and the control of fermentation, 

 and descriptions of the diseases and insect enemies of tobacco. 



Investigations concerning seed wheat, C. W. Burkett {Kansas iita. Rpt. 

 1908, pp. T-XII). — The text of the state law of 1907, authorizing the importa- 

 tion of seed wheat is given, together with a partial account of the observations 

 of the director of the station during a trip to Turkey and Russia for the pur- 

 pose of investigating the sources of seed wheat supply and arranging for im- 

 portations. Brief descriptions are given of the 17 varieties of wheat imported 

 for trial at the station. 



The fertilization of wheat, P. Lavallee (Jour. Agr. Prat., n. .sen, 18 {1909), 

 A'o. 39, pp. .'fS'i. .'i3'>). — An account is given of a combination test of varieties of 

 wheat and of superphosphate as a fertilizer on a clay soil. 



The varieties tested were Hatif Inversable, Ble de Noe, Rouge de Bor- 

 deaux, Japhet, Precoce d'Avrille, Bon Fermier, Blanc a Epi Rouge, and Jaune 

 a Barbes. Jaune a Barbes was the latest single variety to ripen but produced 

 the highest yield of both grain and straw. The second in yield was Hatif 

 Inversable which was also the earliest of all varieties tested. The average 

 yield for all varieties was at the rate of 3,022 kg. per hectare (about 2,690 lbs. 

 per acre). This was 471 kg. per hectare more than was obtained on neighbor- 

 ing farms, and is deemed to justify the application of superphosphate at the 

 rate of 400 kg. per hectare before sowing. 



Zapupe: A new type of fiber plant, J. B. de Santisteban (Zapupe: Nuevo 

 Tipo de Planta Fibrosa. Mexico, 1909, pp. 56, figs. 11).— The industrial and 

 natural history of the plant are outlined, and Agave zapupe, A. lespinassei, A. 

 endlichiana, A. aboriginum n. sp., and A. deweyana are described. Notes on 

 the cultivation of the plant and status of the industry are presented and a 

 bibliography appended. 



[Wyethia mollis], A. A. Heller {MuJilenbergia, 5 (1909), Xo. 9. pp. 131, 

 132). — This plant, locally known as mule ears, is most abundant at altitudes of 

 6,000 to 8,000 ft., and is important as a forage crop for sheep. Nearly all of 

 the 15 species of the genus are native to the Pacific coast and only W. mollis 

 and W. amplexicaulis are found in Nevada. W. lanceolata is local in the Blue 

 Mountains of Oregon. W. arizoniea and IF. scabra are found in the southern 

 Rocky Mountains and W. amplexicaulis and W. helianthoides in the northern 

 Rocky Mountains and the Great Basin. Seven species are confined to California. 



Certain Californian Thalictra, PI L. Greene ( Muhlenbergia, 5 (1909), Xo. 

 9, pp. 128-131). — Tlialictrum polycarpum is renamed T. ametrum and more fully 

 described. T. mendocinum, T. magarum, and T. lutiiisculum are described as 

 new.
