Yates county 



Two borings have been made at Penn Yan near the outlet of 

 Lake Keuka. John T. Andrews furnished the following memo- 

 randa of a well drilled for him about 1893. It was started on the 

 Genesee shale a short distance above the Tully limestone.

First layer of salt 90 feet thick Second layer of salt 35 feet 



at 1200 thick

The well furnished gas but not enough to utilize. 



At the Fox and Curtis mill another boring, 400 feet deep, fur- 

 nished enough gas to run the mill for several months and still 

 yields enough to heat one or two houses. 



Two miles from the lake outlet Mr May has sunk a receiver 

 over a vent in the bottom of the canal, from which he has ob- 

 tained, for several years, surface gas enough for his kitchen 

 range. 



At Dundee a boring, of which I was unable to obtain a record, 

 was made several years ago and is said to have passed through 

 salt. 1 



The accompanying map, showing the distribution of petroleum 

 and natural gas in southern Allegany county, has been prepared 

 by Prof. John W. Greenwood, assistant teacher of science in 

 the Masten Park high school, Buffalo, whose long residence in 

 the petroleum region has specially fitted him for this work.
