meeting into little chips Then the dolomites become more thick-bedded, with often goes in between. These have a thickness of about 150 ft. In the base of this series appear the first recognizable fossils: Cystia cystiniformis, a small spirifer related to I. oarnacensis, small cup corals, and numerous a prostrate Agryphora. About 20-ft below the dolomites have some fossils and partly silicified. Here the ends predominate many cup corals, Eridiphyllum, Acervularia david- sni, Camarotrochia near saphir, hospidula ornis (no one specimen was seen). About ten-foot higher there is a ft bed filled with a branching Favosites. Then a bed of Acervularia, alternating with Favosites. In this way the fossils, all siliceous, appear in rows to the top. But it is not easy to make a good collection. The Agryphora is the commonest good fossil. This ends the Oerminian including the basal crag and sandstone about 580 ft thick, Resedae. The Mississippian lie in sharp contact upon the dark dolomites of the Oerminian. It is a dis- onformable contact. The whole Miss. is given a thickness of 250 ft, and this appears to be correct. It is a thick bedded series gray-white limestone
