SOILS FERTILIZERS. 213 



" The soils most in need of tile drainage are the Clyde clay and the Miami clay 

 and clay loam, though almost all of the types are materially improved by 

 tiling." 



Soil survey of Muskogee County, Oklahoma, G. B. Jones, C. Van Duyne, 

 E. Scott, and H. W. Hawkek {U. S. Dept. Agr., Advance Sheets Field Opera- 

 tions Bur. Soils, 1913, pp. 4S, pis. 2, fig. 1, map 1 ) . — This survey, issued August 

 4, 1915, deals with the soils of an area of 520,960 acres in eastern Oklahoma, 

 which includes three physiographic divisions, namely, the prairie plains, of 

 nearly level to rolling topography; the wooded uplands, a part of the Ozark 

 Uplift, and consisting of a rugged escarpment with a nearly level crest, deeply 

 intersected by an extensive system of small and intermittent streams ; and bot- 

 toms and terraces along the Arkansas and Canadian rivers. The county is 

 drained by the Arkansas and Canadian rivers through numerous tributaries. 



The county has a great diversity of soils, which are grouped in three classes 

 as residual prairie soils, mountain soils, and alluvial bottom land soils. Forty 

 soil types of 15 series are mapped, of which the Gerald series is the most exten- 

 sive. The prairie soils include the Gerald, Oswego, Spearfish, Bates, and Leslie 

 series and rock outcrop ; the mountain soils include the Hanceville and Dekalb 

 series and rough stony land; and the bottom soils comprise the Yahola and 

 Osage series, occupying the first bottoms, and the McLain, Reinach, Brewer, 

 Muskogee, Shawnee, and Teller series, occurring on second bottoms to high 

 terraces. 



Soil survey of Jackson County, Tennessee, R. F. Rogebs and J. H. Deeden 

 {U. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 1913, pp. 29, 

 fig. 1, map 1 ) . — This survey, made in cooperation with the Tennessee Geological 

 Survey, was issued July 29, 1915. It deals with the soils of an area of 201,600 

 acres in the northeastern part of middle Tennessee. The county lies in the lime- 

 stone section and includes the highlands of the uneroded Highland Rim section, 

 a larger area of slope land between this and the stream bottoms, a large extent 

 of stream bottom lands, and considerable steep gullied land lying along the 

 sloping areas. The surface drainage is rapid. 



The soils of the county are classed in accordance with the physiographic sec- 

 tions. Eighteen soil tj-pes, of 6 series, are mapped, of which the Clarksville 

 series, including gravelly loam, stony loam, and silt loam, is the most extensive, 

 followed closely by the Hagerstown series. Applications of organic matter and 

 phosphatic fertilizers are beneficial. Erosion represents a serious soil problem 

 in the area. 



Soil survey of Jefferson County, Texas, W. T. Caetek, Je., L. R. Schoen- 

 mann, T. M. Bushkell, and E. T. Maxon (?7. S. Dept. Agr., Advance Sheets 

 Field Operations Bur. Soils, 1913, pp. ^7, pis. 3, fig. 1, map 1). — This survey, 

 issued November 10, 1915, deals with the soils of an area of 588,800 acres in 

 southeastern Texas, which is divided into uplands comprising the gi'eater part of 

 the county ; a flat, almost level coastal prairie ; and lowlands consisting of a 

 broad belt of marshy land. Practically all the drainage is into Sabine Lake and 

 thence into the Gulf. The soils are grouped into two distinct divisions, (1) old 

 upland soils of the coastal prairie, and (2) recent soils, which are coastal marsh 

 or sea flats subject to overflow by salt water at extreme high tides, and recent 

 bottom lands along the streams and marshy lowlands in the upland portions of 

 the county. Including 4 miscellaneous soils, 21 soil types of 9 series are mapped, 

 of which the Lake Charles clay, silty clay loam, and very fine sandy loam and 

 the Lomalto clay are the predominating types.
