814 EXPERIMENT STATION RECORD, 



fig. 1, map 1). — This survey, made in cooperation with the Florida State Geo- 

 logical Survey, was issued July 24, 1914. It deals with soil characteristics and 

 crop adaptabilities of an area of 344,960 acres in northeastern Florida, the 

 topography of which varies from flat to hilly. The soils of the area are broadly 

 grouped into sedimentary, alluvial, and cumulose soils, and their greatest gen- 

 eral requirement is said to be drainage, which should be followed by liming. 

 Fourteen soil types of six series are mapped, with Portsmouth fine sand pre- 

 dominating. Although only a small part of the county is under cultivation, 

 agriculture is said to be entering a period of development. 



Soil survey of Gordon County, Georg-ia, J. O. Veatch (f7. 8. Dept. Agr., 

 Advance Sheets Field, Operations of the Bureau, of Soils, 1913, pp. 70, fig. 1, 

 map 1). — This survey, made in cooperation with the Georgia State College of 

 Agriculture, was issued July 10, 1914. It deals with soil characteristics and 

 crop adaptabilities of an area of 238,080 acres in northwestern Georgia, which 

 consists of three principal topographic divisions, viz, a narrow mountainous 

 area extending practically the entire width of the western boundary of the 

 county, a mountainous area occupying the extreme eastern part, and a great 

 valley approximately 20 miles in width lying between. There is a diversity of 

 soils which are principally residual in origin. Thirty-nine soil types of 21 series 

 are mapped, the loam and silt loam classes predominating. It is stated that the 

 agricultural i)o.ssibilities of the county have hardly been realized. 



Soil survey of Miller County, Georgia, R. T. Allen and E. J. Grimes ( U. S. 

 Dept. Agr., Advance Sheets Field Operations of the Bureau of Soils, 1913, pp. 

 34, fig. 1, nwp 1). — ^This survey, made in cooperation with the Georgia State 

 College of Agriculture, was issued August 22, 1914. It deals with soil charac- 

 teristics and crop adaj)tabilities of an area of 176,000 acres in southwestern 

 Georgia, the topography of which is flat to gently rolling, varied here and there 

 by limestone sinks. The soils of the area are derived from the Coastal Plain 

 deposits and are consolidated and unconsolidated. Drainage is for the most 

 part good and practically all of the upland portion of the county is said to be 

 well suited to tillage operations and to the use of labor-saving machinery. Sev- 

 enteen soil types of nine series are mapped, the Norfolk sandy loam with its two 

 phases being the most extensive and important. 



Agrology of Sahel, I. Pouget, F. L^onardon, and D. Chouchak (Agrologie 

 du Sahel. — /. Sahcl d'Algcr. Algiers, 1913, pp. 8^; ahs. in Rev. CUn. ScL, 25 

 {191.'t), No. 10, pp. 531, 532). — The results of phy.sical, mechanical, and chemi- 

 cal analyses of soils of the region are reix)rted and discussed with reference to 

 the ease with which the soils may be cultivated and with reference to plant 

 nutrition. A geological chart of the region is also given. 



Study of Hungarian soils by means of their water solutions, R. Balleneg- 

 GER {FiJldtani Kozlony, J,3 {1913), No. 7-9, pp. 317-32J,; ahs. in Intermt. Inst. 

 Agr. [Rome], Mo. Bui. Agr. Intel, and Plant Diseases, 5 (1914), No. 3, pp. 

 336, 337). — ^Analyses of water solutions, as well as determinations of moisture, 

 electrical conductivity at 18° C, and alkalinity were made on samples of 75 

 typical Hungarian soils. See also a previous note (E. S. R., 30, p. 516). 



The author concludes from the results that the water solutions may be used 

 to characterize the various types of soils. Thus the water solutions of the poor, 

 gray forest soils were found to contain the least soluble matter. On the other 

 hand, the very fertile Alfold soils were found to be rich in soluble matter. The 

 distribution of the soluble matter also varied in the different types of soil. 



Some adsorption phenomena in soils and kaolin, J. E. Harris (Jour. Phys. 

 Chem., 18 {1914), No. J,, pp. 355-372; abs. in Jonr. Chrm. Soc. [London}, 106

 tigations are reported which show that the liberation of acid when soils are
