This coal waspractically the same as that mined in the Scalp Level district ofPennsylvania, winch was used in all the locomotive tests made by thePennsylvania Railroad Company at the Louisiana Purchase Exposi-tion in 1904. Its characteristics as a locomotive fuel were thereforewell known. The Lloydell coal is a very friable, low-volatile bitumi-nous coal, and the carloads selected for the tests consisted of run ofmine.
