iiig sufficient quantities of finer material to render it slightly sticky 

 when wet. The color varies from a light brown to a yellowish or 

 reddish brown and, as the surface soil usually contains some organic 

 matter, its color is darker than that of the subsoil. In texture and 

 structure the subsoil is usually similar to the soil material. On 

 account of the light, loose, incoherent nature of the soil, it is subject 

 to drifting when the surface is not protected. Beds of stratified sand 

 and fine gravel are commonly present at varying depths below 6 feet. 



One body of this phase of the Wind River sandy loam occurs south 

 of the town of Hood River, near the center of a large body of the 

 typical soil. Near by are a number of smaller bodies of the phase, 

 but as they are seldom more than an acre or so in extent it is imprac- 

 ticable to show them on the map. The surface of the soil is very 

 uniform. Drainage is excessive. 



The soU is almost entirely under cultivation, and when properly 

 handled it has proved well adapted to the production of apples and 

 strawberries. It would also give excellent results with truck crops. 

 Owing to the sandy nature of the type, the addition of organic matter 

 in some form is necessary in the production of aU crops. The soil 

 also requires copious irrigation. 



The foUowiiig table gives the results of mechanical analyses of the 

 soU and subsoil of the typical Wind River sandy loam and of a single 

 analysis of the soU of the light phase of the type:

WIND RIVER FINE SANDY LOA>f. 



The soil and subsoil material of the Wind River fine sandy loam 

 is a friable, brown or light-brown fine sandy loam, containing a 

 relatively large proportion of coarse and medium sand. The material 

 is not marked by any decided change in color or texture, though the 

 shade of brown becomes somewhat lighter with depth. Basalt rock 

 underlies the type and seems to have an extremely kregular surface, 

 so that the depth of the soil is subject to sudden variations. In 

 many places the soil is but a few inches in depth, and rock outcrop 

 is common, while within a short distance it may be 10 or 12 feet deep. 

 Some fine, waterworn gravel, derived from higher lying masses of 

 volcanic rock, is present in places, but seldom in sufficient quantities
