2939 July 29 Monday, North Vernon, Ind. Left Cincinnati and the C. & O. at 8.20. At North Vernon we were late 20 minutes and missed connection for Madison. Had to await until 5.18 p.m. Just east of North Vernon may be seen the Rock Ohio shale again or mere Hackle shale free of the latter type, gray flinty, crumplyrite. One mile east of the station in a small stream valley may be seen the Hamilton magnesian limestone about 16 feet thick holding Mucropermia media, S. novii, Trochidiptera aciniformis, Shepherdina concava, O. perplanus, Phacops Parretus etc. The fossils are by no means abundant. art. The peculiar feature of these beds are their decided dolomitic character and that the limestones are distinctly saw crocket. The limestone beds are decidedly so and about 8 feet may be regarded as saw crocked. My two points are in those layers. The upper six feet are apparently not seen crocked have one foot with bands of chert hiding the points mentioned above. On the west side of the stream the beds continue for at least 12 feet down so that the Devonian is here at least 28 feet thick. These lower layers are more dolomitie - finely crystalline.
