 The C. 6 A.
 Since 1903, the year following the blowing in of the original plant, James Woods has been superintendent of C. & A. smelter, and is accredited with some of the ablest work in the smelt- ing industry.
 The ore bedding plant of the new shelter is one of the very best in it's arrangement that has yet been devisd. The stock pits will carry a large ad- vance tonnage, relieving the smelter from worry about possible occasional Interruption to transportation lines through accidents.
 The Ore-receiving bins are equipped with chutes for feeding the ore into he hoppers or conveyor feeders. The bins are equipped on both sides with conveyor feeders inch} which con- vey the ore direct to the crushers To- cated at the east end of the ore-re- civing bins, having a capacity of 600 tons The old storage trestle serves as an approach to these bins. From the crushers at the end of the
 bins the ore is conveyed up an in- cline to the crushing and sampling plant, which has capacity of 200 tons an hour when screening out the large sizes for the blast furnaces. The building is of steel and concrete throughout 40X4S feet, and five stories in height.
 Mill In Two Sections The mill is divided into two sections, which can be run independently of each other. Each section has crush ing and sampling department. Ore is cut four times by Snyder automatic samplers, and a sample weighing 1.6 or 32 pounds, as desired, per ton of ore passing through. is obtained. The plant is flexible and the ore may be crushed and screened and discharged at any desired size
 From the sampling and crushing plant the material passes to the beds. The bedding scheme is practically a duplicate of the Cananea system. Three beds of coarse and three beds of fine material are provided, each having a capacity of 10000 tons. A bed for coke, having capacity of 5000 tons, is also provided. The coke is dumped from the cars into the coke-receiving to the furnace charge bins or coke storage bed Reclaimers similar to the Cananea retaining machines reclaim the material from the fine and coarse beds. The coarse ore and coke are con- veyed up an incline to the ore and charge bins directly over the blast furnace charge floor. The fine ore is conveyed up a similar incline to the roaster plant.
 Herreschoff Roasters The roaster plant contains twelve 21-foot 6-inch diameter Herreschoff roasters, having a capacity of approx imately 80 tons of fine ore day. The roaster plant has title and steel dust chamber of 60x140 feet. 70 feet high,
 equipped with baffles and wire. The roof of this chamber and blast fur mace are of copper. This dust cham Der discharges into a brick lined steel chimney.
 | The main shelter building is 222x460 | feet, and contains two blast furnaces l four reverberatory furnaces, six con- verters, the copper casting department
 and other adjuncts. Forty eight inch | by twenty blast furnaces are provided
 Ore and coke are discharged directly
 from the bin just over the charge l floor into charge floors on platform scales, and the amount of coke and ore
 for each charge is propelled from the
 scales to the charge doors of the fur
 naces by an electric motor.
 Steel Dust Chamber A steel dust chamber, 60X1S0 feet
 has suitable baffles and wires. Tn, converter gases pass through th, chamber. The gases from this cham
 Der and also the gases from the rever
 beratory boiler pass into a brick-lin'
 steel chimney. 25 feet inside diamete by 305 feet in height.
 In the reverberatory department
 four reverberatory furnaces 19x100 ar
 installed. Foundation for others ar
 at hand. Each furnace is equipped witt
 two TIP h. p. Stirling boilers and a suit
 able water measuring, heating ant
 pumping system is installed. The fur
 naces are charged direct from calcin
 cars, running on track overhead Matte is tapped into two-ton pots am transferred by cranes to the convert CTS. The slag is skinned direct int ! 25-ton pots, running on tracks under heath and just in front of the skim ming end of the furnaces.
 The main converter aisle is 55 feet i width and 240 tons of electrical travel ing cranes of the most modern con struction are installed. There are si Great Falls type converters and tw straight line casting machines, and l considerable amount of auXiliar
