of fucoids on the surfaces of the flags. Similar shales and flags continue 

 for a little distance down the southerly side of the mountain, but the upper 

 beds are soon reached and some of them are very fossiliferous. On one 

 slab Bhynchonella orbicularis, (?) Grammysia sttbarcuata, 3fodiomorpha, 

 Mytilarca and Edmondia were seen and the specimens were remarkably 

 well preserved. The gray sandstones of the group are not exposed along 

 the road, but their fragments are very abundant and the rocks themselves 

 form the summits of the subordinate ridges. The Kimberling anticlinal 

 is crossed at less than half way down the mountain and brings up again 

 at least one of the sandstones. The passage to Vespertine is not easily 

 made out. A mass of red sandstone occurs in a narrow gorge, say half a 

 mile from Seddou, which probably marks the bottom of the Vespertine. 

 Coal belonging to that group has been mined in a small way at half a 

 mile west from Seddon and at about the same distance north-east from 

 that village. A mine has been opened for domestic use at about three 

 miles further east ; but none of these pits was visited. The topography 

 is reversed on the road crossing Brushy mountain, the long gorge being 

 on the southerly side. 



The road in Rich valley lies in Calciferous for somewhat more than sis 

 miles from Seddon or to a little beyond Point Pleasant. The chert ridge 

 is south from the road and attains to considerable height in its eastern 

 extension. The road lies south from the Saltville fault to Point Pleasant, 

 but almost directly beyond that place it turns northward and thence to 

 the road crossing the mountain to Kimberling creek it lies north from the 

 fault. The dips in the limestone seldom exceed thirty degrees, except near 

 the fault, where they become fifty-five and sometimes even more. Expo- 

 sures are very indefinite along the road to Kimberling creek, as it ascends 

 the slope of Brushy mountain. No coal blossom was seen and no coal is 

 digged anywhere near the road. Fragments of the Chemung upper con- 

 glomerate are very numerous at the first summit of the road and the rock 

 forms the crest of the first main ridge. Between this and the second or 

 main summit of the road, fossils maybe obtained in considerable quantity, 

 Rhynchonella, Chonetes, Orammysia and Qoniopliora all well preserved, 

 having been obtained from a single block. Ambocoelia occurs in vast 

 numbers, its casts forming the mass of several tliin beds. From this sum- 

 mit to Kimberling creek, the road is in the shales and flags which are 

 exposed almost constantly thence to the mouth of No-Business creek. 

 The dip is steadily southward, but becomes comparatively gentle along the 

 creek, being barely ten degrees at the mouth of No-Business. There 

 Kimberling changes its course to south-east and evidently flows through 

 Devonian to where it crosses the Saltville fault at two or three miles east 

 from Mechanicsburg. The stream was followed only to witliin about four 

 miles of the fault so that the limits of groups as given on the map are only 

 approximate. Dismal and No-Business creeks, tributaries of Kimberling, 

 take their rise respectively in Sugar Run and Pearis mountains, double 

 outcrops of Medina with Clinton between the outcrops : but the streams
