24 BULLETIN 141, U. S. DEPARTMENT OF AGEICULTUEE. 



While there is some difficulty in securing a good seeding of mixed 

 grasses, clover gives a good seeding and excellent yields. Mixed hay 

 produces an average of about 1 ton per acre, while clover alone yields 

 from 1 to 1J tons per acre at the first cutting with a possible second 

 crop for seed. Red clover is chiefly grown, although the alsike clover 

 is also well suited to production on this soil. 



Some difficulty is experienced in securing a good stand of sugar 

 beets and they are grown only to a very limited extent upon the 

 Clyde gravelly sand. Beans give fairly good yields. 



The Clyde gravelly sand is so thoroughly drained that the longer- 

 growing field crops are not so well adapted to production upon it 

 as the early truck and small fruit crops. As yet, these are scarcely 

 grown at all since the chief areas of the type, as found, are not 

 especially well situated with regard to markets. Considerable areas 

 of the type are not occupied agriculturally. 



CLYDE FINE SAND. 



The Clyde fine sand has been encountered in eight different soil- 

 survey areas, located in New York, Indiana, Illinois, and Wisconsin. 

 A total area- of 74,048 acres has been mapped of which 68,480 acres 

 are found along the terraces bordering the Kankakee River in 

 Newton Count}'', Ind., and Will County, 111. The other areas are 

 small and of little agricultural importance. 



To an average depth of 10 inches or more, the surface soil of 

 the Clyde fine sand is a dark-gray to black, medium to fine sand. 

 It is alwaj 7 s heavily charged with partly decayed organic matter and 

 not infrequently grades into included areas of peat. In such cases 

 the organic matter is found to extend in large quantity to depths of 

 3 feet or more. In other instances, near the margins of sandy islands 

 and bars, which rise above the general level of the Clyde fine sand, 

 there are bordering areas where the dark-colored surface soil is only 

 about 4 to 6 inches deep. In some localities over the more level 

 portions of the type, sandy areas with a shallow covering of organic 

 deposits are also found. The subsoil is a gray sand which varies 

 from dark color near the surface to a lighter gray or ash color at 

 greater depths. The subsoil is sometimes mottled with brown or 

 yellow stains. At the greater depths the sandy subsoil frequently 

 becomes somewhat compact and sticky through the presence of larger 

 proportions of silt and clay. The type is stone free in both soil and 

 subsoil and even gravel is of rare occurrence. 



In all of the smaller areas of its occurrence the Clyde fine sand 

 occupies small depressions within the area of other sandy soil types 

 and owes its existence to the deposition of large amounts of organic 

 matter where natural drainage was deficient. These areas mark the
