Panoramic view of Grant smelter at Denver, where millions of dollars' worth of gold, silver, copper, lead and zinc are separated each year. This picture gives a panoramic view of this busy place. First, the furnaces and the men dipping out bullion, other men are filling slag pots and hauling them away. A car carrying great chunks of yellow metal ascends a sharp incline. A horse pulling a big slag mold slowly drags the immense weight to dump, where it is cast over the brink in fiery stream.
