214 EXPERIMENT STATION RECORD. 



The county is drained almost entirely by the Salt River and its tributaries. 

 Many areas in the county are in need of drainage. The soils of the county are 

 grouped according to origin into residual, glacial, loessial, and alluvial soils. 

 Eleven types are mapped, of which the Putnam silt and Shelby loams are the 

 most extensive. " There is a general need in Ralls County for the more 

 extensive growing of clover and cowpeas, the moi-e careful and liberal use of 

 manure and of green fertilizers, the application of lime, deeper plowing fol- 

 lowed by more persistent surface cultivation, to collect and hold moisture, and 

 the intelligent use of commercial fertilizers." 



Soil survey of Cass County, Nebraska, A. H. Meyee, R. J. Scarboeough, 

 ET AL. (U. 8. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 1913, 

 pp. 46, fig. 1, map 1). — This survey, made in cooperation with the University of 

 Nebraska, was issued October 12, 1914. It deals with the soil types and crop 

 adaptabilities of an area of 353,280 acres located in the extreme eastern part of 

 Nebraska and comprising three general topographic divisions, viz, uplands, ter- 

 races, and river bottoms. In texture the majority of the upland and terrace 

 soils are silty, while those of the bottom lands vary from a loose, incoherent 

 sand to a heavy clay. Seventeen soil types are mapped, of which the Marshall 

 silt loam is the most extensive and the most important for grain farming. 

 Every part of the county is said to be, in general, well drained. Grain farming 

 is the chief type of agriculture practiced. 



Soil survey of Forsyth County, North Carolina, R. T. At.t.ex and R. C. 

 JuBNET {U. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils', 1913, 

 pp. 28, fig. 1, map 1). — ^This survey, made in cooperation with the North Caro- 

 lina Department of Agriculture, was issued October 31, 1914. It deals with 

 an area of 253,440 acres in northwestern North Carolina, which topograpliically 

 is a high plateau dissected by numerous streams and having a generally rolling 

 and uneven surface. Drainage is said to be well established, the greater part 

 of the area being drained by the Yadkin River and its tributaries. The soils 

 of the county are of residual and alluvial origin. Six types are mapped, of 

 which the Cecil series is the most important and extensive, covering more than 

 SO per cent of the county. " Most of the soils of Forsyth County are capable 

 of being built up and maintained in a high state of productiveness." 



Soil survey of Union County, South Carolina, 0. Lounsbury et al. {TJ. S. 

 Dept. Agr., Advanee Sheets Field Operations Bur. Soils, 1913, pp. 36, fig. 1, 

 map 1). — This survey, issued November 9, 1914, deals with an area of 327.6S0 

 acres in the northwestern part of South Carolina. The general topogi'aphy of 

 the county is that of a modei'ately sloping plain thoroughly dissected by stream 

 erosion. "Topographically most of the land is suitable for agricultural opera- 

 tions, but there are many slopes sufficiently steep to cause the soils to erode 

 badly under cultivation, unless terraced or left in timber or grass." The drain- 

 age is to the southeast, eventually entering the Broad River. The soils of the 

 county are separated into 15 different types, 12 of which occupy the residual 

 uplands and 3 the alluvial bottom lands. The Cecil sandy and Cecil clay loams 

 are the most extensive types. "Average crop yields are low, owing to poor 

 practice rather than poor soils. . . . Commercial fertilizers are depended upon 

 for crop production, and little attention is given to the increase or maintenance 

 of the organic supply of the soils." 



Soil survey of Henrico County, Virginia, W. J. Latimer and M. W. Beck 

 (U. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 1913, pp. 38, 

 fig. 1, map 1). — ^This survey, issued October 15, 1914, deals with an area of 

 168,960 acres near the center of Virginia, the topography of which varies from 

 gently rolling or hilly to gently inidulating or level. The county embraces a 

 large variety of soils, ranging from well-drained uplands and poorly-drained
