and the third, or " Eoss " well, about two miles up the creek near 

 the forks. Both of the south side wells penetrated the Cornifer- 

 ous limestone, and all three had small flows of gas, but not in 

 commercial quantities. In the summer of 1808 Gaenssler & 

 Fisher drilled a well near their tannery between the Vinton and 

 Ross wells. Sep. 23 gas was struck in the Marcellus shale about 

 25 feet above the tops of the Corniferous limestone, the volume 

 being estimated at 7,000,000 feet a day. After the well had been 

 open several hours, the gage showed a pressure of 650 pounds in 

 one minute, with a. total confined rock pressure of 700 pounds. 

 Mar. 31, 1899, the well, while in use, showed a pressure of 650 

 pounds. 



Gaenssler & Fisher's second well, drilled later near the pre- 

 ceding, had a confined rock pressure of 650 pounds with an esti- 

 mated output of 3,000,000 feet a day. The gas horizon in this 

 well was 50 or 60 feet below the top of the Corniferous. 



Marcellus shales. The porous nature of the first rock renders it a likely 

 receptacle; but the range of gas horizons, from 150 to 200 feet in vertical 

 hight, indicates extensive Assuring in the Corniferous and underlying lime- 

 stones and consequent cavities for reservoirs. The conditions here seem 

 favorable for a gas supply lasting through several years. B. F. Whiting, 

 of Springville N. Y„ who has been drilling wells near Gowanda, furnishes 

 me the following notes of wells sunk by him, of which he had no complete 

 record. 



Well sunk for Gaenssler & Fisher on the Parks farm near Dayton, 

 Cattaraugus co. This passed through 500 feet of drift without striking 

 rock and was then abandoned. 



Another well was drilled at Skinner hollow SV 2 miles northeast of Cat- 

 taraugus. The record held by the gas company gave the depth as 1962 

 feet, but Mr Whiting thought it was 2160. The well was barren. 



The well at Otto, sunk for Mr Richardson, penetrated the Corniferous 

 limestone and was continued 50 feet into the shales below, total depth 

 2750 feet. Barren. 



A well sunk by Mr Whiting at New Oregon, Erie co. also for Mr Richard- 

 son, was 2100 feet deep. It was flooded out by salt water after passing 

 through the Corniferous limestone at 2100 feet. 



A well was being drilled (June 1900) at Farmersville, 17 miles east of 

 Delevan by John McMann.

 of the New York state geologist for 1885, 1885 and 1897.
