stone on account of the rough surface of the rock rather than from the amount of sand 

 contained in it. The soil contains a cjuantity of very tine mica, which gives it a soapy 

 or grea-sy feel." Analyses are reported which show that the first contains about 14 

 per cent of clay, 54 per cent of silt, 4 to 6 per cent of organic and volatile matter; the 

 second, 7 to 12 per cent of clay, 42 to 54 per cent of silt, 5 to 6 per cent of organic and 

 volatile matter. 



Soil surii'ii of Montijnineni Connlij, Ohio, C. W. Dorseij and G. X. Coffeij (pp. 85-102). — 

 This county, all of which was surveyed, covers 480 square miles and is also an 

 important tobacco-producing district. The soils are all of glacial origin, 6 types 

 being recognized. The Miami clay loam, a light soil of uniform texture and composi- 

 tion, is the most important soil formation and covers nearly 80^er cent of the C(junty . 

 "The Miami clay loam is a strong productive soil, adapted to general farm crops and 

 to the type of tobacco most in favor at the present time for cigar fillers. The soil is 

 a loose light loam, aV)out 12 in. deep, resting on a sticky clay loam that dries out> 

 into small cubes, which work up like gravel when disturbed." In the analyses of this 

 soil reported the clay varies from 11.62 to 37.37 per cent, the silt from 26.4 (in sub- 

 soil) to 65.8 per cent, the organic and volatile matter from 2.68 to 3.86 per cent. 



Soil survey of Cecil County, Md., C. W. Dorsey and J. A. Bonsteel (pp. 103-124). — This 

 district covers about 375 square miles and is dix-ided into 2 distinct areas, in each of 

 which are 5 types of soil varying in character from almost l)arren to highly productive. 

 "It is situated in the extreme northeast corner of Maryland, and lies partly within 

 the Piedmont Plateau of crystalline rocks and partly within the Coastal Plain 

 formation with its gravels, sands, and clays." 



Soil surrey of St. ^fory, Cahert, and Kent counties, Md., J. A. Bonsteel (pp. 125-186). — 

 These counties, bordering on Chesapeake Bay, lie wholly within the Coastal Plain 

 and have areas, respectively, of 360, 218, and 315 square miles. Xine types of soil, 

 rarely occurring in continuous tracts, were recognized in St. Mary and Calvert coun- 

 ties, and 7 in Kent County. The soil tj'pes included loam, gravel, sand, clay, and 

 swamp. The most extensive type of soil in St. Mary County (41 per cent) is the 

 Leonardtown loam, which " consists of a silty yellow loam, fine and powdery when 

 dry, but puddling to a plastic clay-like mass when thoroughly wet. On redrying, 

 this mass usually bakes to a hard, firm surface, or if stirred before being sufficiently 

 dried, it clods up into hard lumps. The subsoil consists of a brittle mass of clay 

 lenses, lumps, and fragments separated from each other by seams and pockets of 

 medium to fine sand." The most extensive tyi^e of soil of Calvert County (42 per 

 cent) is the Norfolk sand, a coarse sand resting on a sandy subsoil 3 ft. or more in 

 depth. The predominating t\'pe of Kent County is sassafras loam. "The soil 

 proper consists of a fine brown loam, which is often slightly sandy, especially in the 

 ea.stern part of the county. It extends to an average depth of about 9 in. and is 

 underlaid by a uniform yellow loam subsoil. The subsoil varies in thickness from 

 about 20 in. to a maximum of 5 or 6 ft." 



Soil surrey from Rideiyh to Xeirhern, X. C, W. d. Stnitlt (pp. 187-205). — This covered 

 an area about 9 miles wide and 105 miles long in which a great variety of soils were 

 found, 17 types being recognized. "Of these, the Cecil clay, derived from the 

 weathering of crystalline rocks of the Piedmont Plateau, is a strong clay soil adapted 

 to wheat and grass; the Selma silt loam, the finest type of bright tobacco soil; the 

 Norfolk sand, a tyi)ical truck land; the Garner stony loam, a nearly worthless soil, 

 and the Savanna and Pocosnn, representing types of swamp lands which need 

 extensive improvement in the way of drainage before they are of value for crops." 



Soil surrey in Weh(r County, Utah, F. I>. Gardner and C. A. Jensen (pp. 207-242). — 

 This di.strict lies between the (treat Salt Lake and Wasatch Mountain and has an 

 area of about 310 square miles. Eight types of soil are described, the most important
