Lima, Avon and Caledonia. Rushville, Yates co. and Gorham, 

 Ontario co., have a few wells. Farther east in Onondaga county 

 deposits have been found at Baldwinsville, Phoenix and Warner, 

 and in Oswego county at Fulton, Pulaski and Sandy Creek. The 

 latter occur in the Trenton limestone, the lowest horizon at 

 which gas has been found in the State. 



The returns received from the various producers of natural 

 gas show that the total value of the output in 1904 amounted 

 to $552,197. Owing to the fact that some of the larger companies 

 operate at several localities, it has been difficult to distribute 

 the output according to the districts in which it was made. The 

 following statistics are, however, close approximations: Alle- 

 gany-Cattaraugus field, $183,830; Erie county, $254,899; 

 Chautauqua county, $31,822; Niagara, Wyoming and Genesee 

 counties, $18,855; Livingston, Seneca, Ontario and Yates counties 

 $32,451; Onondaga county, $15,350; Oswego county, $14,990. 



One of the notable developments during the year has been 

 the opening of large wells at Silver Creek, Chautauqua co., by 

 the Home and the South Shore gas companies. The wells are 

 connected by pipe lines with Dunkirk and Forestville. At West- 

 field a deep well is being drilled with the view of exploring for 

 gas in the formations below the Devonic. The Brocton Gas & 

 Fuel Co. of Brocton drilled two wells during the year. In the 

 first well, which reached a depth of 2263 feet, the Medina sandstone 

 was encountered at 2225 feet, and gave a flow of about 10,000 

 cubic feet daily. A pocket of sulfurous gas was found between 

 the depths of 400 and 600 feet. The second well was sunk to 

 2261 feet below the surface, but yielded only sulfurous gas from 

 the Devonian strata. In Erie cotmty the Springville Gas Co. 

 put down several wells near Springville and Collins. The property 

 of the Genesee Natural Gas Co. of Geneseo has been taken over 

 by the Empire Gas & Fuel Co.

The oil-bearing territory of New York embraces the north- 

 eastern extension of the Appalachian field. The Bradford dis- 

 trict, which reaches its widest development in Pennsylvania includes 

 a small area in Cattaraugus county, and there are several pools 

 in Allegany county forming the Allegany field, though they are 

 sometimes grouped with the Bradford. The productive strata 

 are fine grained sandstones of dark brown color, locally called 

 "black sands." They belong to the Chemtmg formation of the
