Abstract
This Bureau of Mines report describes the preparation characteristics of three samples collected from the kidney seam, in the northern field of the anthracite region. Removal of the sink 1.70 Specific gravity material from the samples collected would result in greatly reduced ash contents at yields in excess of 90 percent. The kidney seam, in the locations sampled, proved to be a low-ash anthracite containing an unusually high percentage of float 1.45 Specific gravity material.
