planted to wheat, oats, or corn. Some com is planted on newly 

 broken sod. Wheat is occasionally drilled in between the com rows 

 in the fall. 



The land is easily handled and does not require heavy teams or 

 strong farm machinery for its cultivation. It can be plowed under 

 any moisture condition without injury. The soil is somewhat in- 

 coherent and has a slight tendency to blow when not carefully man- 

 aged. 



The selling price of the Tripp fine sandy loam ranges from $20 to 

 $30 an acre, depending uj^on its improvements, and location with re- 

 spect to roads and markets. Owing to its small extent on most 

 farms where it occurs, it is usually sold in connection with soils of 

 other types and has a tendency to increase the general value of the 

 land. 



The soil should not be left longer than is necessary without a pro- 

 tective covering. Applications of barnyard manure help to check 

 drifting and at the same time apply needed organic matter. 



TEIPP VEBY FINE SANDY LOAM. 



The Tripp very fine sandy loam, to a depth of 8 to 10 inches, is a 

 brown to grayish-brown, very fine sandy loam. In places it is 

 slightly compact, but for the most part it is loose and friable. The 

 soil is relatively high in the finest grade of sand and silt and low in 

 material coarser than fine sand. 



The surface 6 inches contains slightly more organic matter than 

 is found in the Tripp fine sandy loam and for this reason is more 

 coherent. In a few places the soil, having been modified by wind- 

 blown material, approaches a loamy very fine sand in texture. 



The upper subsoil consists of a light -brown to ashy-gray silt or 

 very fine sandy loam, which at about 20 inches generally changes into 

 an almost white, loose, floury calcareous silt, much resembling the 

 lower subsoil of the Rosebud very fine sandy loam. Locally the sub- 

 soil does not differ in texture from the surface material, being a very 

 fine sandy loam throughout the 3-foot section. 



The type occupies a relatively small area in Banner County. It 

 occurs in scattering bodies on the higher terraces and benches, chiefly 

 along Pumpkin Creek and its tributaries. The largest area lies south 

 of Funnel Rock, and extends up one of the tributaries of Pumpkin 

 Creek. Two small bodies were mapped on the west side of Willow 

 Creek. On the south side of Pumpkin Creek, in the sec. 25, T. 19 

 N., E. 53 W. there occurs a small but typical area. The soil is com- 

 posed of material brought down from the Ogallala, Arikaree, and 

 Brule formations, reworked and deposited by streams. 



In the extreme western part of the county, along the Nebraska- 

 Wyoming boundary line, there is a body of very fine sandy loam
