The Upper Ozark clay or shale is 2 feet 8 to 10 in this thick. The upper part is more shaly; the lower part is harder and merges into the Ozark lime. it one, from which it is sepa- rated by distinct. The following fossils were found in it: Atropa reticularis, rather abundant. Meristennid shell, smooth, finely striated. Collected, Spirifer 10 Jelicatino=run trum in Crispia. Trans- verse striations sharp. See drawings in Two note book. The upper Ozark beds are exposed at the road [illegible] corner southeast of the bridge. In the base of the Laurel Limestone at the same lo- cality were found the fol- lowing fossils: Atropa reticularis Spirifer crispus. The Laurel Limestone is ex- pored along the road on the tann side. Its total thickness is at least 35 feet and possibly 40 feet or mo more thick. It is extensively quarried just east of Clermont in Bul dit County. Here the upper 24 feet of the Laurel lime- stone are extensively qua rried, but the quarries have been sunk to depths of 30 feet at times. The bedding of the limestone is good, its color is light blue and it much resembles the quarry stone of Percee Valley and Louisville. Along the top of the quarried site near Clermont is found a 11 foot layer of thin clay shales, probably the equivalent of what I have called the Waldron shale, in southern Indiana. Above these shale just east of Clermont, we see formerly quarried at least 25 feet of a very dolomitic gray carbonous limestone, closely resembling the magnesian limestone of Springfield Almo. It cuts across Stratum arms old argus, a little small ler and more resistant than the ordinary Pentamerus
