6, pp. 28). — The changes made since January 1, 1910, in the classification of 

 the soils of the United States are given, and the new types established in dif- 

 ferent soil provinces are described. 



Soils of the Eastern United States and their use, XXIV, XXV, J. A. 

 BoNSTEEL, (U. 8. Dept. Agr., Bur. Soils Circs. ^7, ^8, pp. 15 each). — These cir- 

 culars deal respectively with the following soil types, as surveyed and mapped 

 by the Bureau of Soils: 



Circular 47. — The Orangeburg Sandy Loam, of which a total of 507,648 acres 

 in 28 different areas in 7 States has been surveyed and mapped. 



The surface soil is a gray or brown sandy loam of variable texture, grading 

 into a red, sandy clay, and at greater depths into a stiff red clay. This type 

 is particularly well suited to the production of Upland cotton and is also a 

 fair corn and winter oat soil. " Increasing areas of the type are being planted 

 to peaches, chiefly the Elberta. The fruit produced is of good quality, and 

 the trees when- located upon properly selected sites are long-lived and thrifty." 



Cireular ^8. — The Orangeburg Fine Sand, of which a total of 475,008 acres 

 in 18 different areas in 6 States has been surveyed and mapped. 



The surface soil of 15 in. or more is a gray or brown fine sand, or occa- 

 sionally a fine sandy loam, grading into a sticky red fine sandy loam which at 

 a greater depth becomes sandy clay. The topography is rolling or somewhat 

 hilly and, together with the sandy texture of the soil, affords good drainage. 

 "The type is subject to excessive erosion in some areas, particularly wliere 

 the upland portions break down with sharp slopes toward the major stream 

 drainages. The Orangeburg fine sand is a fair cotton soil. It is not so well 

 suited to the production of corn and winter oats, which, with cotton, constitute 

 the staple crops. . . . The Cuban cigar filler tobacco is the most important 

 special crop adapted to this type. For improvement in soil efficiency the first 

 need is the restoration of organic matter to the surface soil." 



The soils of Sullivan County, R. O. Doneghue et al. {Missouri Sta. Bui. 

 92, pp. 453-486, pi. 1). — This bulletin contains a report of a soil survey, including 

 a soil map of Sullivan County, INIissouri, describing the natural features, agri- 

 culture, and soil types of the region. Mechanical analyses of the different soil 

 types are included. 



The soils of the comity are all of glacial and alluvial origin and are grouped 

 broadly as upland and lowland soils. The following types are described and 

 mapped: Shelby loam, Putnam silt loam (3 phases), Wabash silt loam, Wabash 

 clay loam, and stream wash. The Shelby loam, which is the principal type of 

 the area, is considered " well suited to general farming." 



The soils of Audrain County, R. C. Doneghue and B. W. Tillman {Mis- 

 souri Sta. Bui. 93, pp. 491-514, pl. 1 ) • — Data similar to the above are presented 

 for Audrain Covmty. 



" The soils are of three principal kinds — glacial, residual, and alluvial. Of 

 these the upland prairie silt loam of glacial origin is much the most important, 

 both on account of its extent and also its productiveness." The soil types de- 

 scribed and mapped are Putnam silt loam, Shelby loam, rough stony land, 

 Leslie clay, Waverly silt loam, and Waverly sandy loam. The most extensive 

 of these types is the Putnam silt loam. 



Report on soils, etc., in Central Park, New York City, G. B. Maynadier 

 {[Nciv York, 1911], pp. 30). — Pursuant to a report setting forth the unfavoi-able 

 soil conditions existing in Central Park, New York City, the author was author- 

 ized to undertake a study of this soil with a view of determining its quality and 

 adaptability for lawns. The mechanical and chemical analyses reported were 

 made in the laboratory of the Bureau of Soils of this Department.
