18 EXPERIMENT STATION KECOED. [Vol.35 



deals with the soils of an area of 389,700 acres in northwestern Louisiana 

 which lies wholly within the Coastal Plain province. The topography varies 

 from flat to rolling and consists of sedimentary uplands, alluvial terraces, 

 and first bottom lands. In addition to meadow, 21 soil types of 11 series are 

 mapped, of which the Rustou, Susquehanna, Ocklocknee, and Lufkin very fine 

 sandy loams cover 30.9, 12.4, 10, and 9.9 per cent of the area, respectively. 



Soil survey of Montg'omery County, Maryland, W. T. Caetee, Jk., and 

 J. P. D. Hull (U. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 

 1914, pp. 39, pis. 5, fig. 1, map 1). — This survey, made in cooperation with the 

 Maryland Geological Survey and issued March 25, 1916, deals with the soils 

 of an area of 309,760 acres in the center of the southwestern boundary of 

 Maryland. 



"The topography varies from almost level or gently rolling to strongly roll- 

 ing and hilly, being prevailingly rolling. . . . Throughout the county the sur- 

 face drainage is good." The area lies almost entirely within the Piedmont 

 Plateau province, only a narrow strip being in tlie Coastal Plain province. 

 Tlie soils are grouped as (1) residual soils and (2) soils derived from the un- 

 consolidated material of the Coastal Plain and recently deposited material 

 along streams. Seventeen soil types of 13 series are mapped, of which tlie 

 Chester loam is the most extensive type and is considered the most important 

 soil in the county. It covers 40.4 per cent of the area and the IManor loam 

 covers 16.9 per cent. 



Soil survey of Clinton County, New York, E. T. Maxon and W. R. Cone 

 (f/. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 191^, pp. 37, 

 fig. 1, map 1). — This survey, made in cooperation with the New York State 

 College of Agriculture and issued March 18, 1916, deals with the soils of a 

 well-drained area of 671,360 acres in northeastern New York. The topography 

 is rolling to hilly and precipitous. The soils are of glacial, lacustrine, and 

 alluvial origin. Exclusive of six miscellaneous types, 26 soil types of nine 

 series are mapped, of which the Coloma soils are the most extensive types, the 

 Coloma stony fine sandy loam and fine sandy loam covering 21.5 and 17.1 per 

 cent of the area, respectively. The Gloucester stony fine sandy loam covers 

 13.9 per cent of the area. 



Soil survey of Trumbull County, Ohio, G. N. Coffey, J. Woodward, and 

 J. M. Snyder {U. S. Dept. Agr., Advance Sheets Field Operations Biir. Soils, 

 1914, PP- 53, figs. 2, map 1). — This survey, made in cooperation with the Ohio 

 Experiment Station and issued March 21, 1916, deals with the soils of an area 

 of 405,120 acres in northeastern Ohio, the surface of which is level to rolling 

 with .some small areas of steep and hilly land. 



Trumbull County lies entirely within the late Wisconsin glaciation and the 

 soils are almost entirely of glacial origin. Including muck and peat, 23 soil 

 types of 11 series are mapped, of which the Volusia clay loam and silt loam 

 cover 23.2 and 20.3 per cent of the area, respectively, and the Trumbull clay 

 loam and silt loam 13.9 and 10 i)er cent of the area, respectively. 



Soil survey of Raleigh County, West Virginia, W. J. Latimer ( U. S. Dept. 

 Agr., Advance Sheets Field Operations Bur. Soils, 1914, pp. 34, fig. 1, map 1). — 

 This survey, made in cooperation with the West Virginia Geological Survey 

 an<l issued March 28, 1916, deals with the soils of an area of 391,040 acres 

 in soulhern West Virginia lying wholly within the Allegheny Plateau. The 

 greater part of the surface of the county is extremely rough and dissected. 

 The .soils are of residual, old alluvial, and alluvial origin. Including rough 

 stony land, 14 soil types of 5 series are mapped, of which the Dekalb series, 

 iiiclu<ling silt loam, stony silt loam, silty clay loam, stony loam, loam, and 

 fine sandy loam, con.stitute 82.8 per cent.
