wash from the surrounding soils. Generally used only for pas- 

 ture, although thorough drainage converts it into land well adapted 

 to wheat and corn.

MISCELLANEOUS RESIDUAL SOILS OF THE PRAIRIE REGION. 



Lincoln sandy loam. — The soil is a light-gray to brown sandy 

 loam from to 15 inches in depth, resting on a lighter colored 

 material slightly more sandy than the soil. Occupies low, flat 

 areas bordering streams, and is a pure alluvial in origin. Not sub- 

 ject to overflow, and in general well drained. Best adapted to 

 corn and alfalfa, which sometimes suffer from drought owing to 

 the loose porous nature.

Benton loam. — A light-brown or grayish silty loam from 3 to 12 

 inches deep, often containing small fragments of shale and lime- 

 stone, resting on a subsoil of lighter color, almost wholly made up 

 of partially decomposed shale, but carrying a small proportion of 

 limestone, also in various stages of disintegration. At a dej)th of 

 from 25 to 36 inches the rotten shale and limestone in the subsoil 

 often appear as soft chalky particles. The soil occurs along the 

 banks and ridges bordering streams, and the topography is rough 

 and broken. The drainage is rapid, and if anything too thorough, 

 while the steeper slopes are subject to erosion. The soil is resid- 

 ual, being derived from layers of fossiliferous shale and limestone. 

 Supports a good growth of grasses, and because of its rough, uneven 

 surface it is used mainly for pastures. On the more level slopes 

 Kafir corn and sorghum are grown. Well adapted to stock 



raising.
