NATIONAL HILL, PA (NATIONAL NO. 2)

There were three sub-companies of U.S. Steel involved in coal mining: H.C. Frick Coke Co., United States Coal & Coke Co. (Southern W.Va. and Eastern Ky.), and National Mining Company. National Mining operated their No. 2 mine in South Fayette Township from circa 1905 to about 1930. (National No. 1 was nearby at Morgan, No. 3 was at Muse, and No. 4 in the Monongahela Valley near New Eagle, whose reserves may have evolved into the Maple Creek mine?)
