By J. A. Bonsteel, Scientist in the Soil Survey. INTRODUCTION. The surface soils of the Ctyde series are dark gray, dark brown, or black in color. The subsoils are gray or sometimes yellowish in color and mottled with yellow and gray, but not with red, in practi- cally all cases. The surface of nearly all members of the series is level, with only slightly rolling or ridged areas where some of the types rise above the general level of the surrounding country. In nearly all of the more extensive areas of their occurrence, and in all of the smaller tracts, the surface of the different soils of the Clyde series is depressed below that of surrounding soils of other series. The soils of the Clyde series have been formed either by direct deposition as sediments in old glacial lakes, which have since been drained by natural processes, or they have resulted from the accumulation of more or less mineral matter and a large amount of partially decayed organic matter in small lakes, ponds, and swampy depressions occurring within the glaciated region of the north- eastern and north-central States. In the majority of instances the larger areas of the soils of the Clyde series occur within more or less well-drained basins of old glacial lakes. The soils of the Clyde series grade into deposits of muck and peat on the one hand and into the more completely drained soils of other series of the glacial lake and river terrace province, or of the glacial and loessial province, on the othe*r. Note.—This bulletin discusses the origin, characteristics, and uses of the Clyde series of soils; it is suitable for distribution in New York, Ohio, Indiana, Michigan, and Wisconsin. 55812°—Bull. 141—14 1.
