James Hall, State Geologist, 



Sir : — In this report are included the results of geologic studies in Erie 

 county, X. Y., begun during the summer of 1895 and continued to the close 

 of that year. The purpose of the investigation was to ascertain the bound- 

 aries of the formations for the geologic map of the state, and to collect data 

 regarding economic products derived from rocks found within the county. 



Respectfully yours, 



IRVING P. BISHOP.
