The . importance of the origin and improvement of grasses and clovers, 

 H. WiTTE {Tidskr. LandtinUn, 1910, pp. 13; abs. in Bot. Centhl., lH {1910), 

 No. Ji2, p. -'il6). — Tables and descriptive text show the yielding power and 

 other characters of varieties of clover and grass tested by seed improvement 

 nnions. The yields of varieties from foreign countries are graphically indi- 

 cated, practical conclusions are drawn from experimental data, and the im- 

 provement of native forms is discusse<l. 



Points on the indigenous and acclimated forage crops of Argentina, I, 

 C. D. GiROLA {Apuntes sohre algimas Forrajeras Indigenas y Aclimatudas 

 de la Repuhlica Argentina. Buenos Aires, 1910, pp. 132, pis. 10). — The author 

 devotes a separate chapter to each of the following: Brome grass {Bromus 

 unioloides) crabgrass (Digitaria sanguinalis), yellow foxtail {Setaria glauca), 

 meadow grass {Poa annua), rye grass (LoUurn bnisiUanum), Paspahini nota- 

 tum, spear grass (Stipa sp.), alfalfa {Medicago saliva), white clover (Trifo- 

 lium re pens), bur clover {Medieago denticulata) , sweet clover (Melilotus sp.), 

 and blueweed {Eehiuni pluntagineum). A botanical desci'iptiou of each is 

 followed by a statement of its cultural and climatic requirements, the results 

 of chemical analyses, and directions for its production. 



[Experiments with field crops, Barbados, 1909-10], J. R. Bovell {Imp. 

 Dept. Agr. West Indies, Rpt. Local Dept. Agr. Barbados, 1909-10, pp. 21). — 

 Each of the lines of work noted in preceding report (E. S. R., 23, p. 334), was 

 continued in 1909-10. Tables report the strength and values of Sea Island, 

 Silket, and other cottons; the yields, flavor, and other qualities of the sweet 

 potatoes tested ; the yields of economic colocasias, and meteorological data col- 

 lected during 1909. During the year 25 legumes, most of which were edible, 

 were grown to obtain seed for more extensive tests. 



[Experiments with cotton and sugar cane] L. G. Corrie and J. Mitchell 

 {Ann. Rpt. Queensland Acclim. 8oc., 46 {1909). pp. 10-16, 17, 18, 26, 21).— 

 Discussions of the distribution of varieties of sugar cane and of fresh impor- 

 tations accompany a report of the work. Average yields for 3 and 4 years on 

 black soil were 10,120 lbs., 9,503 lbs., and 9,224 lbs. of saccharose per acre, re- 

 spectively, for B6, 204, B3, 747, and B3, 922 as compared with 6,670 lbs, per 

 acre produced by the standard variety White Transparent. A cotton gin was 

 set up, but the little cotton that matured was of indifferent quality. 



[Manurial experiments with potatoes and turnips]. A, Macpherson {Jour. 

 New Zeal. Dept. Agr., 1 {1910), No. 5, pp. 375-379). — On an exceptionally rich 

 soil the lowest gain in yield of potatoes over the uumauured plat followed an 

 application of 2 cwt. of superphosphate, 1* cwt. of bone dust, and 1* cwt. of 

 dried blood, while the highest gain, nearly 1 ton per acre, followed an applica- 

 tion of the same mixture with the addition of 1 cwt. of potassium sulphate. 



A table states the results of applications of 7 different fertilizer mixtures to 

 turnip plats on each of 8 different farms. 



A successful alfalfa and truck farm in southeastern Ohio, W. A. Lloyd 

 {Ohio. Sta. Circ. 107, pp. 3-19, figs. 10). — The author outlines the operations by 

 a means of which net returns of $3,375 were obtained during 1909. The crops 

 grown were alfalfa, corn, wheat, potatoes, melons, and vegetables. The farm 

 is located 5 miles from an industrial community of " probably 16,000 to 18,000 

 people." Its soil and drainage and the owner's methods of management are 

 stated. 



Investigations of the phosphoric acid and potash requirements of mead- 

 ows, P. LiECHTi {Landw. Jalirb. Schweiz. 24 {1910), No. 4, pp. 357-384, PJ- 

 1). — The author reports in detail the results of fertilizer tests on 33 experi- 

 ment fields in the Canton of Bern, Switzerland, Thomas meal, supenihosphate, 

 potash, calcium carbonate, and liquid manure were applied, singly or in various
