fossils of any kind were found to prove it. Above this there is a covered 

 space (beds Xo. 51 and 52) of 1,300 to 1,500 feet, which is refciTed to 

 the Ked-beds or Triassic. The whole is covered by a thickness of Jurassic 

 strata, overlaid by about 2,000 feet of Cretaceous. From this it appears 

 very probable that the remains of plants found by Rev. Mr. Lakes first, 

 and after him by Prof Scudder, represent part of the first series of beds 

 No. 18 to 50, all exposed and as yet hypothetically referred by Dr. 

 Peale to the Carboniferous and the Permian. The exact location of the 

 plant-bearing beds in the section of Dr. Peale may probably be easily 

 determined.
