Sep. 18 - Sunday. With Parke strolled over the collecting ground of three years ago, saw nothing particular. Paid particular attention to the Illinois horizon and the Coralline group. The latter lies just beneath the former. Of the Illinois gone our about 5 feet though the same rock with these fossils has a greater thickness. The Coralline horizon is thinner bedded, lighter in color with the fossils much more distinct. The common fossils are the Turrilites, cup corals and Spirifera ericson that can be seen if the Illinois zone is only a few feet in thickness. Then there is a stiff grany clays for about 30 feet to a bench or flat which I take to be the stratoline. Sep. 19. Monday Left with Parkeby for Krien at
