106 BULLETIN OF THE 



of these Permian beds from the Trias above, thoagh such a sep- 

 aration was easily made from tlie strata below. 



Mr. Powell remarked that the continuity of these strata with 

 strata overlying the local Carboniferous of the Uinta Mountains 

 had been traced out. Mr. King had also traced the continuity 

 of the same beds from the Great Basin through the Wasatch to 

 the slopes of the Uinta Mountains, connecting the horizon with 

 that ascertained by Mr. Powell. Thus, the equivalence of the 

 widely separated exposures of the Great Basiu, the Uintas and 

 Arizona rested upon stratigraphic evidence, independently of 

 palseontological, and the palceontoiogical evidence now confirmed 

 the conclusions originally based upon the strata themselves, for 

 the fossils found by Mr. King were substantially the same as 

 those found by Mr. Waleott.
