stated that the glacial till upland soils, having a gently rolling to hilly topog- 

 raphy and good drainage, are by far the most extensive and important in the 

 county. 



Soil survey of Kandolph County, North Carolina, R. B. Hardison and S. O. 

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

 pp. 34, fig. 1, map 1). — This survey, made in cooperation with the North Caro- 

 lina Department of Agriculture and issued April 8, 1915, deals with the soilB 

 of an area of 479,360 acres in central North Carolina, the topography of which 

 is gently rolling to hilly and seniimountainous. Uharie and Deep rivers drain 

 the greater part of the county and the south-central part is drained by the east 

 and west prongs of Little River. 



The soils of the county are derived mainly from tvvo rock belts, the most import- 

 ant of which is closely associated with the Carolina Metamorphic Slate and 

 Volcanic Belt and extends over about three-fourths of the county. In the north- 

 ern end of the county and a larger part of the eastern section the rocks are 

 mainly granite with some intrusive rocks. Fifteen soil tj-pes, of six series, are 

 mapped, of which the Georgeville series, including silt loam, silty clay loam, and 

 stony loam is the most extensive. Commercial fertilizers are in general use 

 throughout the county and corn and wheat are the most important crops. Re- 

 peated deep plowing of the soils followed by intensive surface tillage is necessary, 

 especially for wheat growing. " Best results with crop rotations are had \\here 

 . . . clover or cowpeas can be turned under at the time of breaking the land and 

 where a liberal application of lime is made either immediately before or imme- 

 diately after breaking." 



Soil survey of Stark County, Ohio, C. N. Mooney, H. F. Tuttle, and A. 

 BoNAzzi (J7. S. Dcpt. Agr., Advance Sheets Field Operations Bur. SoUs, 1913, 

 pp. 39, fig. 1, map 1). — This survey, made in cooperation with the Ohio Experi- 

 ment Station and is.sued March 15, 1915, deals with the soils of an area of 371,200 

 aci'es in northeastern Ohio, the topography of which is rolling to hilly. The 

 drainage is into the Ohio River thrt)Ugh the Tuscarawas and Mahoning rivers. 

 The soils include iipluiid, terrace, and tlood plain soils of residual, glacial, and 

 alluvial origin. Including muck and peat, nineteen soil tjTOs, of eight series, are 

 mapped, of which the Wooster silt loam is the most extensive. The Volusia 

 series is second in extent. 



The composition of the soils of the Texas Panhandle, G. S. Fbaps (Texas 

 Sta. Bui. 173 (1915), pp. 5-25).— This bulletin, the fourth of a series (E. S. R., 

 30, p. 420), contains a description of the soil types of 26 counties in the Texas 

 Panhandle, with notes on their present agricultural uses and productiveness, and 

 chemical analyses of about 57 samples of these types, together with an int»^rpre- 

 tation of the results. The author concludes that most of these soils are well 

 supplied with phosphoric acid, potash, and lime, while nitrogen appears to be the 

 element most liable to become deficient. 



Soil survey of Logan and Mingo counties, West Virginia, "W. J. Latimer 

 {V. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 1913, pp. 30, fig. 

 1, map 1). — This survey, made in cooperation with the West Virginia Geologicjil 

 Survey and issued May 8, 1915, deals with the soils of an area of 557.440 acres 

 in southwestern West Virginia, the topography of which is rough and broken 

 with narrow stream valleys containing very little smooth bottom land. 



The soils of the area fall into three general groups, namely, upland or residual 

 soils, terrace or old alluvial soils, and first bottom or recent alluvial soils. Nine 

 soil types, representing four series, are mapped, the Dekalb stony silt loam occu- 

 pying 88.9 per cent of the area.
