22 MARINE REVIEW. {January 2, supply bins, from whence it is taken to the furnaces by the scale cars. The bins for storage are all of the same cross section and are fifty-six in number. There are four large coke bins over the center of each skip pit, in which the coke is fed directly into the skip car which takes it to the furnace. There are twenty-eight bins for use for ore or limestone, being seven for each furnace. The Brown machines are independent motor driven, the span of the bridge being 225 ft. and the cantilever 105 ft. The back leg of the machine is mounted on rails 16 ft. from center to center. The motors are located on the truck of the back leg of the machine and are enclosed in a suitable engine house. The opera- tors' house is located directly above and on the side of the leg of the machine. THE FURNACE EQUIPMENT. There are four furnaces, built and erected under contract with the Riter-Conley Mfg. Co. of Pittsburg. The furnace stacks are 20 ft. in These stacks are of steel, 11 ft. diameter inside the lining, and 200 ft. high The boilers are connected to these stacks by overhead breeching. They are of the Babcock & Wilcox type, amply strong for working ptes- sure of 150 Ibs. to the square inch. The engine house is 44 ft. 2 in. span and 200 ft. long. It contains five pairs of blowing engines, built by the E. P. Allis Co. and commanded by one 30-ton electric overhead traveling crane. These engines each have a high-pressure cylinder 50 in. in diameter, a low-pressure cylinder 96 in. in diameter, with a blowing tub 96 in. in diameter, all of 60-in. stroke. The pump house, which is a lean-to on the engine house, is of 30 ft. span, 200 ft. long, and contains three horizontal Wilson-Snyder compound direct-connected circulating pumps, having steam cylinders 18 and 82 in. in diameter. The bronze plungers are 24 in. in diameter by 36 in. stroke. The pumps are each rated at 6,000,000 gallons per twenty-four hours. All pumps are connected to an exhaust line extending to the end of the VIEW OF STOCK PILES AND BLAST FURNACE. COAL WASHER AND COKE OVEN PLANT. diameter at the bosh and 85 ft. high.

The bustle pipe surrounding the columns is 46: ft. in diameter. The tuyere stacks, twelve in number, are of an improved type with ball joints and adjustable blow pipes. The skip-hoist leading from under the stock bins to the top of the furnace is ofstructural steel and carries two skip cars which rest at the bottom in a steel cased pit.

These pumps obtain their water from the harbor, and will be connected to a 20x85-ft. standpipe, which will supply water for circulating and cooling purposes. The pump house contains a pair of surface condensers built by the Borthey Mfg. Co. of Toronto. Through these the return water from the furnaces will be used for condensing purposes. The fresh water supply line leads to the wall of the engitie house and has connection to the 'boiler feed pumps, which are three in number and are duplex, of outside packed plunger type, 14x9x18 in. stroke. These were' built by Wilson-Snyder Mfg. Co.j' Pittsburg. A valve is placed'ion the fresh water line for connection to the main salt water well and to the 'salt water discharge line from the pumps, enabling the use of fresh water in case of emergency for cooling purposes. To the Northey condensers in the pump house there is a connection leading through the wall to a line to the electric power station. This part of the equipment consists of
