Sep.-27-1900 Arrived at Cumberland last night and came stopping with Mr. R. H. Lord. Spent the day at the Devils Back Cone section. We first collected back of the R.R. match box and I soon learned that most of the lower roll here up the hill side has fallen down for the Cliff to the right (west). In this debris I found several large and typical Pentameres and from picking the column of Sep. 26th made [illegible] pretty nearly a draft that the limestone ridges below (east) are all of the Lower Pentameres. Spring up the hill near the top about two feet of other limestone (higher in section) we saw on the face came one large Orthos Matu spinae macrolima, L. rhomboidalis, Strunella punctulifera and Orthotheca amphorhama n. gadicta. This assemblage points unmistakably to the Delthys (von to fifth page.)
