REPORT OF THE DIRECTOR AND STATE GEOLOGIST 



rl3 



legany county has been prepared for publication and accompanies 

 this report. In addition to the work already outlined, records of 

 a few wells in Chautauqua and Cattaraugus counties and of the 

 Jordan and Memphis wells near Syracuse are included. Except- 

 ing the developments in Chautauqua and Cattaraugus counties 

 within two years, the work of Professors Orton 1 and Bishop now 

 covers all oil and gas territory west' of the meridian of Auburn. 



The reports of these gentlemen together with those of J. N. 

 Nevinfi on the slate and emery industries form an important con- 

 tribution to the economic geology of the state. While New York 

 is not rich in the precious metals, it contains mineral deposits of 

 much commercial value, and it is the definite policy to put in 

 popular and practical form all such results of geologic investiga- 

 tion as will be of interest and value to the inhabitants of the 

 state, from whose money this department of the University work 

 receives its support. 



Geologic map 



In the preparation of a new geographic base for the new large 

 scale geologic map, of which a preliminary edition was issued by 

 Prof. James Hall, C. C. Vermeule has been engaged during the 

 summer in reducing, by photography, the new topographic atlas 

 sheets which are being prepared by cooperation between the state 

 government and the United States geological survey, and making 

 from them a tracing which will subsequently be reduced by photo- 

 graphy to form a photolithographic base on the scale of five miles 

 to the inch. In this work only the most reliable material will 

 be used, and, while it is a somewhat slow process, the compila- 

 tion, when completed, will be of great value to the citizens of the 

 state, not only as a medium for communicating its geology, but 

 for the ordinary educational and commercial uses of maps. 



As it appeared that the edition first issued was somewhat 

 unmanageable in character, being supplied only as a wall map 

 mounted on rollers, the precaution has been taken to prepare the 

 new map in sheets of only half the size of those adopted in the 

 first edition. These, either with or without the geology, can be 

 bound in an atlas, and for office use or for the ordinary purposes
