It is also exposed in Faulkner's gulch, a ravine about 5 miles 

 east of Terry's ravine on the road from Smith's Mills to Nash- 

 ville, and a compact layer in the lower part contains brachiopods 

 in still greater numbers, both of individuals and of species. 



Some loose slabs in the gorge of Walnut creek, below the 

 mill at Forestville, from this horizon also, contains brachiopods, 

 but they were not found in place in the Walnut creek section. 



The sandstones cause a cascade at Corey's mill, % mile south 

 of Forestville, and a layer about 50 feet higher, exposed in a 

 small ravine a mile farther south, contains several species of 

 brachiopods, and they also occur along the escarpment on the 

 east side of the creek at Miller's Mills, a mile farther south. 



A layer 4 inches thick, and quite calcareous, that is exposed 

 in the bed of a small brook that flows through Forestville from 

 the east, contains several species of brachiopods. The horizon 

 is about 75 feet above the sandstones. There are several quar- 

 ries and natural outcrops between Forestville and Laona in 

 which the sandstones are exposed. At Laona they appear in 

 the bed and sides of Canadaway creek, and one compact layer 

 5 feet thick has been quarried for more than 50 years. 



In a soft layer in the bed of the stream about a mile south 

 of Laona and 75 feet above the sandstones a few obscure im- 

 pressions of indeterminable cephalopods were found. 



No other representatives of the Portage fauna were found 

 above the horizon of the Laona sandstone, in the Lake Erie 

 section. On the lower surface of a thin sandstone, 10 feet 

 higher, and in the subjacent shales, Chemung brachiopods are 

 common. 



Shumla sandstone (Hall). The sandstones exposed at Shumla 

 2y 2 miles south of Laona are 260 feet to 280 feet above the 

 Laona sandstone. Fossils are very rare here., but a few speci- 

 mens of a small Orthis and a small Productella are distributed 

 through the beds and are quite common in the large concretions 

 in a thick sandstone in the bed of the creek under the bridge. 



The position of the Laona sandstone may be easily traced 

 toward the southwest by the means of a number of small out- 

 crops. It is exposed at Brocton in the bed of Slipperyrock 

 creek near the bridge in the northwest part of the village and
