Abstract
Although many schemes have been proposed for a classification of soils, not any single one seems to have found general acceptance. It is, however, generally agreed that with any method, a final subdivision based on the texture of the soil is highly desirable, even though it only be the sands, loams, and clays of common parlance. Granted then that a classification based on mechanical analyses is called for—though not necessarily as the primary division into groups—it is here proposed to examine some of the various methods so far put forward for dealing with the results of mechanical analyses. Tables of analytical results in themselves are unwieldy and make decidedly uninteresting reading. The comparison of a large number of soils is a slow and tedious process, if it is accomplished only by a study of the figures.
