fossils are not indicative of the age of the district. They are either Upper Salina or Lower Hudson River. If the latter which is probable the case, as we found no Salina fossils in this formation but here a thickness of at least 80 feet. On the way back to Strangy in the creek and 75 feet above the river we found the same assemblage of species as found in the morning high d. Florida. Hudson River about fossils were again found in the debris at the face of a large bluff about one mile of the stream from Strangy. If this entire bluff belongs to one formation, it would give it a thickness of about 80 feet. The fossils collected are at least just Hudson River fossils.
