The topographic features of the desert basins of the United States with reference to the possible occurrence of potash . he drainage. Of these criteria the first two are the most important and both areessentially topographic. It is seldom that the rocks of an area areeither entirely potash bearing or entirely the reverse. The studyof the areal geology is not only seldom conclusive, but is alwayslaborious and is obviously never necessary unless topographic con-ditions are known to be favorable. The first step of the inquiry is,therefore, the study of the topography of the undrained regions, andit is this step only which is taken in the present report. The writerhere sets out to answer the question In what basins has potashprobably accumulated and been, retained in significant amount?With the no less important matters of segregation and position (es-pecially depth) he is not here concerned. The topographic data upon which the report is based .have beengathered from many and various sources.
