As elsewhere noted, East Olean is supplied from Ceres and 

 vicinity by the Producers gas co. The latter corporation has 

 650 subscribers on its line, which also supplies Westons Mills 

 and Portville. 



Chautauqua county 



At Mayville are three old borings of some extent. That known 

 as the Hershberger well was sunk 17 or 18 years ago to the depth 

 of 1800 feet, but no gas was found. The second or McCormick 

 well, 1275 feet deep, was located north of the village. Gas was 

 found at 1175 feet with an initial shut-in pressure of 190 pounds, 

 which fell to 100 pounds in a few days. The metered output was 

 about 9000 cubic feet a day. 



The third or Colton well near the junction of Erie and Water 

 streets, drilled about the same time as the Hershberger well, was 

 at first 900 feet deep. In 1899 the well was cleaned out and 

 drilled to the depth of 1200 feet, when gas was found with a pres- 

 sure of 450 lb. When bailed out for redrilling, 3J barrels of fine 

 amber oil were taken. This must have originated above the 900 

 feet level. 



July 30, 1899, a fourth well was being drilled on the Van Cise 

 lot, about a quarter of a mile northwest of the Hershberger well. 

 It was then down 250 feet in drift without having touched bed- 

 rock. At Chautauqua point there is an old boring which at one 

 time furnished a small quantity of gas. 



A boring was made in the summer of 1899 about one half mile 

 south of the Western New York and Pennsylvania railway star 

 tion within the village of Mayville. The contractor, G. B. Keith, 

 furnishes the following record.

The amount of gas is not reported. 



Another well here (no. 1 ?) has been deepened from 1300 feet 

 to 2300 feet, getting a small vein of gas at the latter depth.
