BRODHEAD CREEK SECTION. 
No. 1475, 01.— Iii Brodhead Creek, at Smith aud Miller's mill (for- 
merly Stokes 7 aud also Wyckoff's), a little below Gravel Place, is an 
exposure of Marcellus sliale of a bluish gray tint with drab markings, 
apparently belonging to the lower Marcellus. The dip is west of north, 
and in two places between 10° and 20°. No fossils were found. 1 
On the highway west of the creek, near the top of the small ridge, 
south of the 3-mile board, are bluish black shales by the roadside, 
probably Marcellus, while on the ridge north of the sign-board and 
house the Hamilton appears. 
No. 1475 5. — Continuing north along the Stroud sburg and Sprague- 
ville highway, at a point a short distance south of the house of E. 
Bouynge, is an exposure of arenaceous slightly calcareous shale by 
the roadside. Fossils are very abundant at this horizon, especially 
Corals and Crinoid stems, and numerous specimens of Brachiopods. 
The rock when weathered becomes rotten and filled with perforations 
left by the solution of the Corals and Crinoid stems.
