620 EXPERIMENT STATION RECORD. [Vol. 36 



Incliifling meadow, 14 soil types of 11 series are mapped, of which the 

 Grenada silt loam, Lexington silt loam, and Vicksburg silt loam cover 24.9, 

 13.2, and 12.7 per cent of the area, respectively. 



Soil survey of the Bitterroot Valley area, Montana, E. C. Bckmann and G. 

 L. Harrington (U. S. Dept. Agr. Advance Sheets Field Operations Bur. Soils, 

 1914, pp. 72, pis. 3, fig. 1, map 1). — This survey, issued January 18, 1917, deals 

 with the soils of an area of 327,040 acres in Ravalli and Missoula counties in 

 western Montana. The valley area is a well marked depression of structural 

 origin. The soils of the area have been derived from residual material, ice-laid 

 and water-laid glacial material, old valley filling deposits, recent alluvial fan 

 material, recent alluvium, and miscellaneous materials. Fifteen soil series, 

 embracing 36 soil types, and two miscellaneous soils are recognized in the area. 

 Of these, rough stony land covers 17.3 per cent, Bass stony sandy loam 9.1 per 

 cent. Burnt Fork stony loam and Victor stony sandy loam each 7.8 per cent, 

 and Waterloo sandy loam 6.5 per cent of the area. 



Geology of Cincinnati and \'icinity, N. M. Fenneman {Geol. Survey Ohio, 

 4. ser., Bui. 19 (1916), pp. 207, pis. U, figs. 59).— This report contains physio- 

 graphic data which may be of use in a study of the soils of Ohio. 



Soil survey of Dorchester County, South Carolina, W. J. Latimer, J. M. 

 Snyder, and C. Van Duyne ( U. S. Dept. Agr., Advance Sheets Field Operations 

 Bur. Soils, 1915, pp. 1^5, pis. 2, fig. 1, map 1). — This survey, issued January 16, 

 1917, deals with the soils of an area of 362,240 acres in the Coastal Plain 

 region of southeastern South Carolina, the surface of which is level to gently 

 rolling. " The northern half of the county is higher and, in general, better 

 drained than the southern part, where there are extensive areas of flat 

 savannas and low-lying, poorly drained land. The bottom lands along the 

 streams are wide and the streams sluggish. . . . 



"The soils of Dorchester County are divided into three classes: (1) Upland 

 or sedimentary soils, consisting of unconsolidated Coastal Plain sands and 

 clays, derived originally from the Piedmont Plateau and the Appalachian 

 Mountains, (2) terrace . . . soils lying above overflow, consisting of old alluvial 

 material derived from the Coastal Plain soils, and (3) first-bottom . . . soils." 

 Including tidal marsh, 27 soil types of 10 series are mapped, of which the 

 Johnston loam, Norfolk sandy loam, and Norfolk fine sandy loam cover 15.4, 

 11.8. and 10.7 per cent of the area, respectively. 



Soils of Grayson, Lee, McLennan, Titus, and Tyler counties [Texas], G. S. 

 FRAPS (Texas Sta. Bui. 192 (1916), pp. 51). — This bulletin contains a descrip- 

 tion of soil types in the counties named, based on surveys by the Bureau of 

 Soils of the U. S. Department of Agriculture previously noted (E. S. R., 16, 

 p. 1059; 19, p. 417; 26. p. 718), together with chemical analyses of represent- 

 ative samples and a discussion of their fertility requirements based in part 

 on pot experiments. 



The soils of Grayson County, covering 1,010 square miles consisting mainly 

 of black prairie lands, were found to be well supplied with total phosphoric 

 acid but low in available phosphoric acid. A number of the soils are low in 

 nitrogen. It is concluded that these soils require legume rotation and the 

 application of acid phosphate. 



The soils of Lee County, covering about 700 square miles, were found to 

 be for the most part deficient in active phosphoric acid and nitrogen. Nitrogen 

 and acid phosphate applications and crop rotations are recommended for these 

 soils. 



The soils of McLennan County surveyed, covering 440 square miles, were 

 found for the most part to be well supplied with phosphoric acid, nitrogen,
