722 EXPEEIMENT STATION RECORD. [Vol.36 



The topography of the uplands varies from level to very hilly. " In general, J 

 the western part of the county, west of the Current River, is the more broken, ^ 

 and large areas are too rough and rocky to cultivate. The southeastern corner 

 of the county is in the Mississippi lowland region. The western part of the 

 county is thoroughly drained by the Current River and its tributaries, and the 

 eastern and northern parts by the Little Black River and its tributaries. The 

 drainage of the Mississippi bottoms is poorly established, there being numerous 

 sloughs and abandoned stream channels." 



The soils of the county are mainly of residual and alluvial origin, with a 

 small area of loessial origin. Including rough stony land, 17 soil tjipes of 9 

 series are mapped, of which the Clarksville gravelly loam, stony loam, and silt 

 loam and Decatur gravelly loam cover 20.3, 19.8, 18.3, and 10.8 per cent of 

 the area, respectivey. 



Soil survey of Lamoure County, North Dakota, A. C. Anderson. F. Z. 

 HUTTON, T. M. BusHNELL, M. Thomas, and M. E. Stebbins (f7. S. Dept. Agr., 

 Advance Sheets Field Operations Bur. Soils, 191^, pp. 53, fig. 1, map 1). — This 

 survey, made in cooperation with the North Dakota Experiment Station and 

 the Agricultural and Geological Survey and issued January 30, 1917, deals with 

 the soils of an area of 729,600 acres in southeastern North Dakota. 



The eastern and central parts are mostly undulating prairie, and the western 

 part is gently rolling to hilly. " Surface drainage is not well established, but 

 Is in most places sufficient where assisted by percolation into the subsoil. . . . 

 The soils of the county fall into four general groups — glacial, glacial-lake and 

 river-terrace, river flood-plains, and eolian soils." Including rough broken land, 

 25 soil types of 10 series are mapped, of which the Barnes silt loam, the Barnes 

 loam, and the Williams loam cover 51.9, 15.3, and 11.9 per cent of the area, 

 respectively. 



Soil survey of Cambria County, Pennsylvania. B. B. Derrick, A. L. Pat- 

 kick, and D. C. Wimer {TJ. S. Dept. Agr., Advance Sheets Field Operations Bur. 

 Soils, 1915, pp. 32, fig. 1, map 1). — This survey, made in cooperation with the 

 Pennsylvania State College and Experiment Station, deals with the soils of an 

 area of 445,440 acres in southwest central Penn.sylvania lying mainly in the 

 Allegheny Plateau. The topography is uneven to hilly and even mountainous 

 in places. All parts of the county are said to be reached by drainage ways. 



The upland soils of the county are of residual origin and the rest of alluvial 

 origin. In addition to rough stony land, 10 soil types of 5 series are mapped, 

 of which the Dekalb gravelly loam, stony loam, and silt loam cover 41.7, 20.6, 

 and 14.1 per cent of the area, respectively. 



A soil survey of the proposed Palouse Irrigation Project, H. F. Holtz 

 {Washington Sta. Bui., 133 {1916), pp. S-I4. pis. 6). — This survey deals with the 

 general characteristics and agricultural value of an area of 103,000 acres In 

 southern Franklin County, Wash. The topography is rolling. The survey was 

 divided into seven areas, and mechanical and chemical analyses and determina- 

 tions of the water-holding capacity were made of representative soil samples 

 from each area. 



Analyses of one hundred West Virginia soils, F. E. Bear and R. M. Saxtee 

 {West Virginia Sta. Bui. 161 {1916), pp. 36, fig. 1). — This bulletin gives a pre- 

 liminary statement regarding the most prominent soil series of West Virginia, 

 together with the analyses of 100 representative soil samples chosen from cer- 

 tain sections of the State. The latter are taken to indicate that many of the 

 soils analyzed are seriously deficient in phosphorus, nitrogen, organic matter, 

 and Itme, while most of them are fairly well supplied with potash. 



It was found that 50 per cent of the soils analyzed contained less than 1,000 

 lbs. of phosphorus per acre to a depth of 6 2/3 in., over 40 per cent contained
