446 The Upper Devonian Deposits of Maryland 



whicli is approximately the elevation at which the same bed occurs in the 

 section west of Berkeley Springs, West Virginia, where the lower strata 

 are well exposed and free from minor folding. The identity of the beds 

 at both places is established by the sequence and by the contained faunas. 

 This is the most easterly section in Maryland and is admirably exposed.
