The GREAT SEARCHLight at Nuremberg, heretofore regarded as the largest in the world, is quite eclipsed by one that has recently been placed on the Woman's Magazine building, St. Louis, Mo. The Nuremberg light, which was described in the last number of The TECHNICAL WORLD, is of 316,000,000 candle-power. The St. Louis light is of 600,000,000 candle-power. On the night of its installation its reflection was seen at Kansas City, 300 miles away. This searchlight is thus by far the largest in existence, and was constructed at a cost of $12,000.
