212 EXPERIMENT STATION EECOED. 



survey, made in cooperation with the Nebraska Soil Survey and issued June 14, 

 1915, deals with the soils of an area of 211,840 acres in middle-eastern Ne- 

 braska, which includes three distinct topographic divisions: (1) Uplands, (2) 

 old alluvial terraces, and (3) first bottom lands. The surface of the upUind is 

 rolling to rough and extremely dissected. The county has well-established 

 drainage to the southeast. 



The upland and terrace soils are of silty texture, while the bottom lands vary 

 in texture from loose incoherent sand to heavy clay. The upland is covered by 

 a bed of loess which varies from a thin mantle to 100 ft. in depth. Fifteen soil 

 types, of 7 series, are mapped, of which the Knox silt loam is the most exten- 

 sive, followed by the Marshall silt loam. 



Soil survey of Saunders County, Nebraska, A. H. Meyeb, E. H, Smies, T. M. 

 BusHNELL, R. R. Spafford, R. R. BruN, and R. J. Scakbobough {U. S. Dept. 

 Agr., Advance Sheets Field OperaVons Bur. Soils, 1913, pp. 52, fig. 1, map 1). — 

 This survey, made in cooperation with the Nebraska Soil Survey and issued 

 June 10, 1915, deals with the soils -^ an area of 487,040 acres in eastern Ne- 

 braska, the topography of which varies from flat in the stream bottoms and 

 terraces to extremely dissected in parts of tlie upland. " There are three dis- 

 tinct topographic divisions: (1) The uplands, derived from loessial and glacial 

 material ; (2) the alluvial terraces, deposited at a time when the streams were 

 flowing at a higher level; and (3) the first bottom lands, embracing the recent 

 alluvium of the Platte River and its tributaries." The county is drained by the 

 Platte River and Walioo and Salt creeks. 



In textui'e, most of the upland and terrace soils are silty, while those of the 

 bottom lands vary from a loose incoherent sand to heavy clay. Including 3 

 miscellaneous types, 18 soil types, of 10 series, are mapped, of which the 

 Shelby silt loam, the Marshall silt loam, the Waukesha silt loam, and the 

 Wabash silt loam are, in their order, the predominating types. 



Soil survey of Rowan County, North. Carolina, R. B. H^vrdison and R. C. 

 JuKNET (U. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 1914, pp. 

 Ifl, fig. 1, map 1). — This survey, made in cooperation with the North Carolina 

 Department of Agriculture, was issue<l September 29, 1915. It deals with the 

 soils of an area of 330,240 acres in west-central North Carolina, the topography 

 of which is prevailingly rolling. The greater part of the county consists of broad 

 interstream areas. The area includes a great variety of soils adapted to a wide 

 range of crops. The upland soils are of sedimentary origin and tlie bottom 

 soils of alluvial origin. Twenty-seven soil types, including 10 series, are mapped, 

 of which the Cecil series is the most important, covering over half the county. 



Soil survey of Paulding County, Ohio, H. G. Lewis and C. W. Shiffleb 

 {U. S. Dept. Agr., Advance Sheets Field Operation's Bur. Soils, 191^, pp. 29, fig. 

 1, map 1). — This survey, made in cooperation with the Ohio Experiment Station, 

 was issued September 8, 1915. It deals with tlie soils of an area of 204,320 

 acres in northwestern Ohio, the topography of which is level to slightly rolling. 

 The drainage is to the northeast through tlie Maumee and Auglaize River sys- 

 tems and there are many large tracts between rivers that have no well-developed 

 natural drainage. 



The soils have a marked uniformity, are of glacial and lacustrine origin, and 

 range in texture from sand to clay. Eight soil types, of 8 series, are mapped, 

 of which the Clyde clay is the most extensive, covering over three-fourths of the 

 area. The Clyde clay consists mainly of swampy, dark-colored soils, while the 

 lighter-colored soils are included in the Miami and Beluiore series, and the 

 alluvial soils in the Genesee series. " In general the darker-colored soils of the 

 county are fairly well supplied with organic matter, while the lighter-coloreii 

 soils are in need of humus. The Miami soils are apparently deficient in liiue."
