The diagram on the following page indicates the relative posi- 

 tions of the more interesting of the line of outcrops that show 

 these High Point sandstones (station 1) to be synchronous with 

 the Portage sandstones at Portageville (station 14). 



Station 2. Wolf gully 3^ miles a little west of south from High 

 Point. An escarpment at the top of the west bank is 30 to 40 

 rods long and shows 35 feet of rock mostly heavy sandstones. 

 No fossils have been found here. 



Station 3. \ mile east of station 2, on the east side of Frink 

 hill. An escarpment in which is a thin calcareous layer, com- 

 posed principally of crinoid stems and bryozoans. Contains 

 many brachiopods. 



Station 4. Ledges on the west side of Knapp hill, 4J miles 

 southeast from High Point. A calcareous concretionary layer is 

 crowded with D. tuberosum and Chemung brachiopods. 



Station 5. One mile east of station 4 the sandstones appear 

 in several small escarpments on north slope of Pine hill. 



Station 6. McClarries's quarry on the hillside east of the vil- 

 lage of North Cohocton. About 30 feet of light blue gray com- 

 pact sandstones in heavy layers are exposed. A thin seam of 

 shale in one of the hard layers contains a few small brachiopods. 

 No other fossils appear. This quarry is evidently in the Portage 

 sandstones but its stratigraphic position in them is not certainly 

 known. It is 5 miles directly south of High Point and 30 miles 

 east and 1 mile north of the cliff at Portageville. The altitude 

 is 1575' to 1600' A. T., indicating an elevation of 300 feet to 400 

 feet or a westerly dip of 10 feet to 13 feet a mile, and a southward 

 dip of 25-30 feet a mile. 



Station 7. A small exposure near the foot of the hill on the 

 north side of the road leading from North Cohocton to Way land, 

 a little east of Dotys Corners. It is about 4 miles west from 

 station 6 and there is not much difference of altitude. A cal- 

 careous layer, similar to the one at High Point, but thinner, is 

 composed of Chmeung brachiopods. 



Station 8. Quarry 2 miles west of Wayland on the north side 

 of the road to Dansville. Altitude about 1400' A. T. No fossils 

 have been observed here.
