Thisfurnace is 17 feetwide, 24 feet throughat the level of the firechamber, and has atotal height of 42^^feet from drawingfloor to chargingtrack. It handles from90 to 100 tons pertwenty-four hours; itscubic capacity is 2400feet, hence the oreremains a little abovetwenty-four hours inthe furnace. It isrun by two shifts offive men each—onefurnace man, twochargers, and twodrawers—and requiresnot quite 2 - cords ofwood per day. Theexcessively low fuelconsumption is parthdue to the high per-centage of iron sul-phide in the ore. 215 The fine-ore furnaces belong nearly all to the tile furnacetype, with the exception of: Livermore Furnace.— [See Fig. 72.] Only
