THE classification of the soils of the Wisconsin drift area of Iowa has been an evolutionary process since first surveys were initiated in the area nearly 5'o years ago. All counties of this area but one, namely, Humboldt County, have been mapped, field work ranging in date from about 1914 to 1935. In the past decade or so, a re-examination of the classification and mapping of the soils of this area has been initiated. These efforts are primarily being associated with the program of Soil Conservation Districts, and with suggestions by land appraisers, from managers, and county agents that the classification of the Carrington series in one or two counties of the area should be re-examined. Although no basic soil surveys are in progress in the area concerned, it is becoming evident that re-classification of a number of soil types is necessary, and also that re-mapping of a number of counties is highly desirable. The present paper, which is in the way of a preliminary report, is being presented at this time to indicate some of the progress made and to discuss some of the problems encountered.
