While most "thermometer" signs register success by rising, that of the Homestake Copper Company of Calumet shows progress by falling. The sign is an indicator of the Centennial No. 6 mine dewatering projects, showing the original level of the water in the mine and its removal to date. The 31st level was reached this past Saturday. Bailing began April 2 when the water was at the 27th level. The thermometer in this case is the mine's shaft.
