THE MINING AND QUARRY INDUSTRY I907 



49 



There has been little change in the production of petroleum 

 for several years past, though the drilling of new wells is not 

 so actively prosecuted as formerly; the maintenance of the out- 

 put at a nearly constant level may be ascribed in a large degree 

 to the relative permanency of the pools. Practically all of the 

 production is obtained by pumping. By using gas engines which 

 are fed by the natural gas that accompanies the petroleum the 

 pumps can be worked at small expense and wells yielding less 

 than a barrel a day are profitable. The product is transported 

 to the refineries by pipe lines. The following companies handle 

 practically all of the output within the State : The Allegany 

 Pipe Line Co., Columbia Pipe Line Co., Union Pipe Line Co., 

 and Fords Brook Pipe Line Co., all of Wellsville; Vacuum Oil 

 Co., of Rochester, and the Tide Water Pipe Co., Limited, of 

 Bradford, Pa. 



The output of petroleum in 1907 amounted to 1,052,324 barrels, 

 as compared with 1,043,088 barrels in the preceding year. The 

 following table shows the total for each year since 1891. The 

 statistics subsequent to 1903 have been compiled from the re- 

 ceipts of oil reported by the companies above mentioned, while 

 the others are taken from the annual volumes of the Mineral Re- 

 sources.
