James Hall, State Geologist. 



Sir: — Tlie report herewith submitted is in continuation of that made 

 by me in the Thirteenth Annual Report, and concerns the inter-relations <>f 

 the various geologic deposits laid down during Portage time, especially as 

 developed through the central region of the State. The stratigraphy and 

 faunal succession in Chenango county, west of the Chenango river, have been 

 previously discussed in some detail. Here I have endeavored to correlate 

 those observations with such as have since been made further westward 

 through the counties of Cortland, Schuyler and Yates. 



Respectfully yours, 



JOHN M. CLARKE. 



Albany, January 1st, 1896.
