Mt. Pleasant. On road leading through middle of three north westward half a mile, Waverly shale light blue, breaks up into small pieces. Kidney nodules, purple brown, dark, with fossils. Found 120 feet above level of hotel at Mt. Pleasant. Found 12 in. above level where brown conglomer- itic sandstone is rather common. The section therefore appears to be equivalent to section 3 in the Cook Hollow. The brown conglomeritic sandstone probably did not exceed 15 inches in thickness and may have been scarcely 1 foot thick. Lower Silurian limestone with plenty of fossils occurs 10 feet below the upper brown conglomerate fragments in the soil. Columbia 1000 Pleasant Grove 1065 Campbellsville, 1050. Lynville 1100 Dodene 1312. Dodens Station. 1312 At station the trip of the Lower Silurian occurs at 1353. The Black shale occurs about 9 feet above the Lower Silurian. The Black shale appears to have a thickness of 12-15 in close, and is inter- ted about 8-10 feet above last ex- posure of Lower Silurian. The sandy phlyptic rock was seen at no locality west of the station. It is probable that the unexposed part below the Black shale is clayey rock belonging to the Lower Silurian. Section probably same as Mt. Pleasant a preceding page. NE of Lynville about 1/2 mile along east side of RR track. A hill near top shows Lower Sil., limestone at 1265, Less than 10 ft. above are several in- cases of Black Shale. Above this are Waverly shale fragments with many fossils.
