574 EXPERIMENT STATION RECORD. 



Analyses of water, H. J. Wheeleu {Rhode Island Sta. lipt. 1S95, p. 394). — Tabu- 

 lated analyses with reference to sanitary condition of 12 samples of water. 



Analyses of waters, M. B. Hardin (South Carolina Sta. Rpt. 1895, pp. 58-61). — 

 Complete mineral analyses of 15 samples of mineral water, and examinations with 

 reference to sanitary quality of 26 samples of drinking water. 



Influence of climate on agricultural soils of Tunis, L. Makcassin {Bid. Agr. 

 et Commerce, Tunis, 1 {1S9G), No. 1, pp. 16-23).— X general discussion of the climatic 

 and soil conditions of this region, with suggestions as to needed investigations bear- 

 ing on the relation especially of water to i>lant production in this drj^ climate where 

 irrigation is a necessity. 



A new^ contribution to the study of fallowing, P. P. Deiiekain {Ann. Agron., 

 22 {1896), No. 11, pp. 515-523). — Experiments during the last year indicated that 

 there was much more water as well as a larger production of nitrates in the soil 

 lying fallow than in that bearing plants. 



The oxidation of the organic matter of the soil, P. P. Deherain and E. 

 Demoussy {Ann. Agron., 22 {1896), No. 7, x)p. 305-337, fig. 1). — A detailed account of 

 experiments previously briefly reported (E. S. R., 8, p. 208). 



Concerning nitrate formation, A. Stutzeh and R. Haktleb {Centhl. Bakt. nnd 

 Par. Allg., 2 {1896), No. 22, p. 701).— K preliminary note. 



Denitrifying bacteria, A. Yogel {Apoth. Ztg., 11, p. 704; abs. in Pharm. Eev., 24 

 {1896), No. 12, pp. 279, 280). 



On denitrification, G. Ampola and E. Garino {Centhl. Bait, nnd Par. Allg,, 2 

 {1896), No. 21, pp. 670-677, fig. 1). 



The distribution of salts in alkali soils under different conditions, E. W. Hil- 

 gard {Forsch. Gel. agr. Phtjs., 19 (1896), No. 12, pp. 20-36, figs. .5).— The main points 

 of this article have been covered by the author in previous papers (U, S. Dept. Agr., 

 Office of Experiment Stations Bui. 30, p. 66: U. S. Dept. Agr. Yearbook 1895, p. 103; 

 California Sta. Bui. 108 (E. S. R., 7, p. 568); Pop. Sci. Monthly, 48, p. 602). 



The conditions of the formation of natural soda, II, P. Melikoff (Aba. in Bui. 

 Soc. Chim. Paris, 15-16 (1896), No. 23, p. 1866). 



Texture of some important soil formations, M. Whitney (U. S. Depf. Agr., 

 Division of Agricultural Soils Bnl. 5, pp. 23, pis. 35). — This bulletin gives a brief dis- 

 cussion of the relation of soils to crop jjroduction, pointing out especially the 

 importance of physical condition and water sup2>ly, and a number of photographs 

 illustrating in a graphic way the texture of some important types of soil, with a 

 brief descriptive text. The jilates show the percentages of gravel, sand, silt, and 

 clay in truck lands of East Hartford, Connecticut; Marley and Salisbury, Mary- 

 land; Boston, Massachusetts; Jamaica, Long Island, New York; Newbern, North 

 Carolina; Providence, Rhode Island, and Norfolk, Yirginia; wheat land of David- 

 sonville, Maryland; grass land of Hagerstown, Maryland; upland loess of Virginia 

 City, Illinois; loess of Nemaha County and Geneva, Nebraska; plains marl of Chey- 

 enne County, Kansas, and Ogallala, Nebraska; tobacco lands of East Hartford and 

 Poquonock, Connecticut; Hatfield, Massachusetts; Lititz and Marietta, Pennsyl- 

 vania; Yuelta Abajo district, Cuba; and Rimboeu estate, Sumatra; bright tobacco 

 lands of Granville County, North Carolina; Lancaster, South Carolina; Green 

 County, Tennessee, and Danville, Yirginia; shipping tobacco lands of Newstead, 

 Kentucky, and Clarksville, Tennessee; White Burley tobacco land of Lexington, 

 Kentucky; Remedies tobacco land of Camajuani, Cuba; and barren clay hills of the 

 Potomac formation, near Baltimore, Maryland. The appearance of soil particles in 

 flocculated and unflocculated condition, and the ijercentages of water maintained in 

 truck, wheat, and grass lauds are also shown. It is shown that the truck soils 

 examined maintained on an average 6 per cent of moisture, the wheat soils 13, and 

 the grass soils 18. 



Notes on Hilgard's elutriation process for soils, A. Mayer (Forsch. Geb. agr. 

 Ph^js., 19 (1896), No. 3, pp. 103-211, figs. ^^).— The comparative merits of the methods 

 of Hilgard and Schone are discussed.
