Report of the State Geologist. 



south is largely covered by soil. However, on the "Barber lot," owned by 

 William Wilcox, there is a small brook along whose course the rocks are 

 partly exposed. In the woods at the foot of a cascade about 110 feet above 

 the top of the shales in Pleasant brook at XVIII A 1 is a fair outcrop of 

 shales which contain an abundance of fossils. There is a continuous exposure 

 of twelve feet of these shales which in both faunal and lithologie characters 

 are similar to the Moscow shales of western central New York. Only a few 

 minutes w ere spent there in collecting, but in that time nineteen species were 

 obtained, all of which, with the exception of Chonetes mucronata, Hall, Cryp- 

 tonella (E/tneHu) LineMceni, Hall, and Liopteria DeKa-yi, Hall, occur in the 

 Moscow shales in the vicinity of Moscow and Livonia, Livingston county, 

 New York, 1 which is the typical region for this subdivision of the Hamilton 

 formation. The complete list of species is as follows :
