Soil survey of Cleburne County, Alabama, H. G. Lewis, C. S. Waldrop, and 

 F. W. KoLB {U. S. Bcpt. Agr., Advance Sheets Field Operation's Bur. Soils, 

 1013, pp. S8, fig. 1, map 1). — This survey, made in cooperation with the State of 

 Alabama and issued May 15, 1915, deals with the soils of an area of 363,520 

 acres in eastern Alabama, comprising portions of the Appalachian Mountain 

 and Plateau province and the Piedmont Plateau province. The topography varies 

 from rough, hilly, and mountainous to gently rolling. The area is drained 

 through the Tallapoosa, Little Tallapoo.sa, and Coosa rivers. The soils of the 

 county are residual in origin, and the Piedmont soils are considered the most 

 important agriculturally. Twenty-one soil types, of eleven series, are mapped, 

 of which the Talladega slate loam is the most extensive, with the Louisa grav- 

 elly loam second. The Talladega series covers 55 per cent of the county. 



Soil sui*vey of Russell County, Alabama, N. E. Bell, L. A. Hukst, and J. M. 

 Snydek ([/. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 1913, pp. 

 50, fig. 1, map 1 ) . — This survey, made in cooperation with the State of Alabama 

 and issued IVIay 17, 1915, deals with the soils of an area of 419,2(J0 acres in the 

 coa.stal plain of eastern Alabama, the topography of which ranges in general 

 from undulating to rolling. The county is drained through tributaries of the 

 Chattahoochee and Alabama rivers. 



The upland soils of the county are formed from materials laid down on the 

 floor of the Gulf, which at one time covered the region. Thirty-eight soil types, 

 of twelve series, and three miscellaneous types are mapped, of which the Sus- 

 quehanna very fine sandy loam, clay, fine sandy loam, and sandy loam, the 

 Norfolk sand, and the Leaf fine sandy loam are the predominating types. It is 

 Ktated that the soils of the county are generally in need of lime and organic 

 matter. 



Soil Survey of Pope County, Arkansas, C. Lounsbtjry and E. B. Debtee 

 (U. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 1913, pp. 51, 

 fig. 1, map 1). — This survey, issued June 3, 1915, deals with the soils of an area 

 of 529,920 acres in central Arkansas. The topography of the northern half of 

 the county is rough and rugged, while that of the southern half is more level 

 and less dissected. The drainage is mainly into the Arkansas River. The soils 

 of the county comprise upland soils of residual origin and alluvial stream bottom
