The wells of Kane district, and those recently drilled in the eastern part of Elk county, find their oil in these sands. They also furnish large volumes of high-pressure gas in the Wilcox pool, at Kane City, Johnsonburgh, and in a number of experimental wells in Elk county. "Reviewing the above, it is seen that all the large deposits of oil and gas thus far discovered in western Pennsylvania have been found in groups Nos. 3, 5, and 7. The greatest output of gas from No. 7 is in the Wilcox pool, located on the West Branch of Clarion river, about a mile and a half north of the Elk-McKean county line. Here are about 30 wells (some of which have shown a pressure of 850 pounds to the square inch), sending gas through three 8-inch lines to Bradford, and thence to Salamanca and Buffalo, 87J miles from the wells, and also east to Olean, Wellsville, and Cameron's Mills, 115 miles. A portion of the gas used on this end of the line is drawn from the Allegany field. Another deposit underlying Kane county supplies that town with all the gaB it can use, and is also being drawn upon by a new gas line recently completed to Bradford. At Joliusoubursh, Elk county, good wells are obtained and the gas is piped about 8 miles and utilized in the town of Ridgway. The rocks of No. 5 hold large deposits of gas in two important fields--Sheffield, in Warren county, and Speechley, in Venango county. From the first, gas is piped to Sheffield, Clarendon, Warren, Corry, and Erie, and also to Jamestown, New York; from the last (where more than 100 wells have been drilled) to Oil City and Tituaville, Franklin, Mercer, and Sharou; Meadville, two lines; aud td Tionesta. "No. 3, as before remarked, supplies all the natural gas now being ...
