the top, Atrypa reticularis is found. The Ozgood limestone is well exposed north of the Whaleridge on the north side of the railroad. It total thickness is 7 feet 8 inches, and consists of a drab colored limestone, parts of it not very well bedded. About 3 feet 8 inches above the base, at the most northern part of the exposure, rather large specimens of Atrypa reticu- laris are rather common. At the junction with the Lower Ozgood shale was found the crude flat Streptelasma? or common in the Ozgood lime- stone near Ozgood Indiana and elsewhere, also Strephm. cera plumbridalis and Atry- pa reticularis. The Upper Ozgood shale con- sists of 3 feet of blue clayey clay, with thin limestone layers intercalated, with the clay and the thin limestone con- taining fossils. Orthis eleg antula, small Rhyrchamella, 2 raised plica, times, 1 in depression Indiana? Atrypa reticularis Streptelasma cancellum? found. cont Orthis flabella with rather num- erous plicatus, Strephlasmna plumbridalis, rather small Spifer Viragensis? collected, and Spifer rizza small also occur in the Upper Ozgood shale, where it is thrown out when the R. R. embankment Near the top Orthis divity a medium size, branching form, atropoid shell, with sinuous and fold in front collected; very at the top in an locality south of the bridge, friends of small size are common. Near Whaler's farm the lower 2 feet of the Laurel limestone are regularly stratified and contain Ostrea accumulum. Above this the exposure continues for 24 feet, parts being very curiosi dul. In places it weathers in a curious manner and is known as the Cliff rock. In the next rail road cut down south of Whalers, the land ind indicating total thickness of 35 feet Laurel limestone and at the spring south.
