valley. Plans have been formed for the exploration of a large 

 tract of land near Reed's Corners, east of Canandaigua, by a 

 Pittsburg company. 



In Steuben county, the North Side Gas & Oil Co. continued 

 the drilling of a well at Ferenbaugh which was started in 1906. 

 After encountering a small flow at 250 feet, the hole was carried 

 down to 2100 feet and shot, but registered less than 40,000 feet 

 a day. A second well of nearly equal depth gave no results. 

 The Steuben Oil and Gas Co. of Hammondsport will sink a test 

 well near Keuka. Drilling has been started near Canisteo on 

 the farm of James E. Wilson. The exploration of the Troups- 

 berg field has been discontinued for lack of success. 



PETROLEUM 



The oil pools found in New York State constitute the northern 

 extension of the Appalachian field which reaches its main de- 

 velopment in Pennsylvania, Ohio and West Virginia. They 

 underlie small areas in Cattaraugus, Allegany and Steuben 

 counties near the Pennsylvania border. The first well was 

 drilled in Cattaraugus county in 1865, while Allegany county 

 began producing about 1880. The oil is encountered in fine- 

 grained sandstones of dark color belonging to the Chemung 

 formation of the Upper Devonic. 



In Cattaraugus county the productive area embraces about 

 40 square miles, mostly in Olean, Allegany and Carrolton town- 

 ships. The pools occur at several horizons from 600 to 1800 feet 

 below the surface. The principal ones, are the Ricebrook, Chip- 

 munk, Allegany and Flatstone. . 



The oil field of Allegany county extends across the southern 

 townships of Clarksville, Genesee, Wirt, Bolivar, Alma, Scio 

 and Andover and is divided into several pools that are considered 

 to be more or less independent. The Bolivar, Richburg and 

 Wirt pools have been most productive. The oil is found at 

 depths from 1400 to 1800 feet. The Andover pool lies partly in 

 the town of West Union, Steuben co., and is tapped by wells 

 from 850 to 1000 feet in depth. The discovery of oil in the town 

 of Granger, on the Livingston county border has been in some 

 respects the most noteworthy addition to the productive area of 

 late years, since the pool is much farther north than any hereto- 

 fore found in the State.
