LOWER SILURIC SHALES OF THE MOHAWK VALLEY I/ 



The next outcrop which furnishes fossils is in a small creek, 

 coming in from the west, at the second bridge above I, about 220 

 feet higher in the section. Here were found (Mus. loc. 3759) : 



2 Corynoides calicularis (cc) 

 Diplograptus foliaceus acutus (cc) 

 Triarthrus becki (c) 



A third fossiliferous outcrop was found along the main Chucte- 

 nunda creek one and three-fourths miles west by south, 70 feet 

 above the preceding. This has furnished (Mus. loc. 3760) : 



3 Diplograptus (Mesogr.) mohawkensis (cc) 

 Lasiograptus eucharis (with colonies) (cc) 

 Leptobolus insignis (c) 

 Triarthrus becki (r) 

 Orthoceras sp. (r) 



There follow continuous outcrops for half a mile, all of which 

 contain (Mus. loc. 3761) : 



4 Diplograptus (Mesogr.) mohawkensis (cc) 

 Lasiogr. eucharis (cc) 



At the end of this series of outcrops, about 30 feet above 3, 

 (Mus. loc. 3762) Lasiograptus eucharis has become by 

 far the prevailing fossil. There occur: 



5 Diplograptus (Mesogr.) mohawkensis (c) 

 Lasiograptus eucharis (colonies) (cc) 

 Leptograptus insignis (r) 



A quarter of a mile farther up, beyond the fourth bridge (Mus. 

 loc. 3763) the following fossils were obtained: 



6 Diplograptus (Mesogr.) mohawkensis (c) 

 Lasiograptus eucharis (cc) 

 Leptobolus insignis (r) 

 Triarthrus becki (c) 



Three-quarters of a mile farther up, (Mus. loc. 3764), just below 

 the village of Minaville and 300 feet above the first outcrop only 



7 Lasiograptus eucharis, and 

 Leptobolus insignis 



were collected. The next outcrop which is half a mile above Mina- 

 ville is the base of the Minaville section, described by Cumings
