in the southwestern section, where they are derived from sandstone." Includ- 

 ing rough stony land, seven soil types of five series are mapped, of which the 

 Hagerstown silt loam covers 77.8 per cent of the area. 



Soil survey of Gage County, Nebraska, A. H. Mkyee, R. R. Bttbn, and 

 N. A. Bengtson (f7. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 

 1914, PP- 4^, fig- 1, inap 1). — This survey, made in cooperation mth the 

 Nebraska Soil Survey and issued June 10, 1916, deals with the soils of an area 

 of 547,840 acres in southeastern Nebraska lying entirely within the glaciated 

 part of the Great Plains province. 



"The topography ranges from almost flat or plainlike to rolling, with steep 

 to abrupt slopes along drainage ways, bordered by rather high rock ledges. 

 As a whole the county is well drained." " The soils of the county are classed, 

 on the basis of origin and mode of formation, into four principal groups, (1) 

 soils derived from loess, (2) soils derived from glacial drift, (3) residual or 

 or partly residual soils, and (4) alluvial soils." Excluding meadow, ten soil 

 types of ten series are mapped, of which the Carrington, Grundy, and Wabash 

 silt loams cover 51.4, 18.4, and 14.7 per cent of the area, respectively. 



The soils and agricultural development of northern New York, E. O. 

 FippiN {Cornell Countryman, 13 (1916), No. 7, pp. 570-575, figs. ^).— This arti- 

 cle deals briefly with the soil characteristics and agricultural conditions of an 

 area of approximately 14,500 square miles, including all of eight counties and 

 parts of six counties in northern New York. The topography is that of a great 

 central mountainous dome receding to low plains. The soils consist of non- 

 agricultural mountain soils, lowland soils, and lake and terrace soils. It is 

 stated that drainage is the most pressing need of these soils and that liming 

 is also necessary. 



Soil survey of Wake County, North Carolina, L. L. Beinkley, N. M. Kiek, 

 R. T. AxLEN and B. B. Derrick ( U. S. Dept. Agr., Advance Sheets Field Opera- 

 tions Bur. Soils, 1914, pp. 45, fig. 1, map 1). — This survey, made in cooperation 

 with the North Carolina Department of Agriculture and issued June 30, 1916, 

 deals with the soils of an area of 537,600 acres lying in the Piedmont Plateau 

 and Coastal Plains regions in central North Carolina. The topography ranges 

 from level to hilly and broken. The county is said to be well drained. The 

 soils are of residual and sedimentary origin. Twenty-two soil types of nine 

 series are mapped, of which the Cecil sandy loam, Durham coarse sandy loam, 

 and Cecil coarse sandy loam cover 21, 14.3, and 10.4 per cent of the area, 

 respectively. 



Soil survey of Geauga County, Ohio, C. N. Mooney, H. G. Lewis, C. W. 

 Shipfler, and O. Gossard {U. S. Dept. Agr., Advance Sheets Field Operations 

 Bur. Soils, 1915, pp. 37, fig. 1, map 1). — This survey, made in cooperation witb 

 the Ohio Experiment Station and issued June 30, 1916, deals with the soils 

 of an area of 263,680 acres in the Allegheny Plateau region in northeastern 

 Ohio. The surface varies from flat or nearly flat to gently undulating or 

 rolling and hilly. 



"The soils are predominantly silty. They are of glacial origin and derived 

 largely from sandstones and shales of Carboniferous age. According to 

 topographic position and mode of formation the soils fall into three general 

 groups — glacial upland, or unmodifled till soils; glacial-lake and river-terrace, 

 or modified till soils ; and river flood plain or alluvial soils, with muck and peat. 

 a cumulose formation." Including muck and peat, 16 soil types of eight series 

 are mapped, of which the Volusia clay loam and loam cover 61.7 and 11.4 per 

 cent of the area, respectively.
