all the total thickness must be over 1000 feet. Above the latter there comes in a series of brick-red shales, that in places is finely rippled and sun-eroded. Bear nothing in the way of fossils under the room tracks, = Dalina series. Nothing of the Shel derby was seen. Of the Oriskany there is a basal black flinty sandstone in thickness as at Cumberland. We saw a number of the Lower Oriskany fossils. Their men not less than 50 feet. Over it then follows a considerable thick- ess of coarse Oriskany sandstones that in the deeper beds pass over into a conglomerate. Under the fossils are again of pure quartz. In these phosphorites, pyrites, Agates, oxides and conglomerates, saw only 10 acres. This section is contoured and faulted so that we did not make out the structure. In this again they mine for a mineral pair carb. It is a residual found between the Oriskany there also seems to be another one between the Oriskany shale top bed and the Marcellus. Have a sample. Beneath the Oriskany either the lowest
