A sixth kiln is on the ground but not erected. The fuel employed is powdered coal. The Finch quarry, situated in the foothills nearby, is equipped with a crushing plant, and the ore is delivered to the calcining plant, five miles distant, over an aerial tram. Since the cessation of war the American mines have not operated continuously. Relatively large stocks were in the hands of consumers at the beginning of 1919, and these were used before new contracts were placed.
