ously carried on, and the results tluit haAc already been attained in 

 Narious ways by tiie Department of Ao-riculture, and other agencies, 

 are discussed. A comparative resume of the ])rincipal (jualitics of 245 

 representative wheats of the world, grown experimentally by the 

 Department of Agriculture, are presented in a table. 



First report of work on the department's test farms for the season 1900, 



B. W. Kiu;oKE ET AL {Bui. North Carolina State Bd. Agr., 2X {1900), No. 11, pp. 6-53, 

 jth. 6). — The work described comprises fertilizer and other tests with corn, cotton, 

 l)otatoes, sweet potatoes, grasses, and leguminous plants carried on at Tarboro and 

 Red Springs farms. An outline of the methods and purposes of the tests is given. 



Tlie experiments with corn showed nitrogen to be most needed in the soil, but, in 

 general, its cost made the increased yiel<l expensive. Applying one-half the nitrogen 

 in the form of cotton-seed meal at planting time and the rest during the growing 

 season gave good results, but suljstituting nitrate of soda for cotton-seed meal as an 

 after dressing proved more effective. Comments are given on all the results, but 

 general conclusions are reserved on account of insufficient data. A paper on Legu- 

 minous plants for forage and soil improvement, by J. F. Duggar, read at a meeting 

 of Commissioners of Agriculture of the cotton States is reproduced. 



Collection and distribution of grass seed — field work ( U.S. Tkpt.Agr., Office 

 of Secretary Circ. 9, pp. 11). — This circular is a brief report to the Secretary of Agri- 

 I'ulture on the work of the Division of Agrostology in the direction of purchasing 

 and collecting seeds and specimens of valuable economic grasses and forage plants 

 for the purpose of distributing them to the various experiment stations, and of the 

 field work for the season of 1900. The work was in charge of C. L. Shear of that 

 Division. A list of particularly promising grasses of which seeds were secured in 

 (piantity is given and the merits of each species briefly noted. This list comprises 

 dry meadow and range grasses, wet meadow grasses, soil and sand binding species, 

 and alkali soil and subalpine species. 



Frost injury to crops and methods of its prevention, A. Tk.vmpe {Landio. 

 Zlsclir. liheinprodnz, 1 {1900), No. £J, pp. 255, 256) — .An article describing in a pop- 

 ular manner the culture of fall grains and calling attention to the importance of the 

 \ariety of grain, kind of seed, and manner of sowing, and the fertilization and 

 preparation of the soil, in resisting cold winters. 



Investigations on the stooling of grains, W. Rimpau {Landw. Jahrb., 29 

 {1900), No. 4-5, pp. 589-628, fi(ji^. S). — This article is a translation of a report on 

 experiments by E. Schribaux, and a series of controversial letters on the subject 

 which appeared in the Jounud d' Agrictdture Pratique. 



Of what value is the stooling of grains? Edler {FiihUug's Landu'. Ztg., 49 

 {1900), Niiy. 22, pp. 850-852; 23, pp. 871-876). — A discussion of Schribaux's work, 

 published originally in the Journal d'' Agriculture Pratique. 



Methods of growing barley of a low nitrogen content for brewing pur- 

 poses on light soils, T. Remy {Centbl. Agr. Chem., 29 {1900), No. 12, pp. 809-811). 



Chicory growing, INI. G. Kains {U. S. Dept. Agr., Division of Botany Circ. 29, 

 pp. 12, Jigs. 3). — A popular publication on the culture of chicory for its various 

 uses. A bulletin on this subject by the same author is abstracted in E. S. R., 10, 

 p. 236.

 graphic; culture, }ii.-<t<)irc, i'r()iiouu(jue. Paris: Georges Carre & C. Naud, 1900, pp. 494, 

 figs. 37). — Part 1 treats comprehensively of the history, botany, and physical and 

 chemical character of cotton, cotton by-products, culture of cotton in the United 

 States and other American countries, diseases and insects affecting cotton culture in 

 Egypt and other countries of Africa, in Europe, and Asia. Part 2 discusses the cot-
