good work, and economy of fuel. Few people, not intimately 
acquainted with such things, know the herculean task it is to 
build ona A few dimensions may give a better idea. The 
furnace, where the smelting is done, is 17 feet in diameter at 
the boshes, and 66 feet high, containing over 9,600 cubic feet. 
When running, this will be kept constantly full of ore and 
coal. The engine for blowing air into this mass of materials 
is of the size of that of a large steamship. The steam is made 
with six boilers, 60 feet long each, which are fired with the 
waste gases from the furnace, thus caught and utilized. The 
smoke-stack is 140 feet high, 24 feet square at the base out¬ 
side, and 8 feet in internal diameter all the way up. The 
hoist for taking up coal, ore, etc., is worked by a separate en¬ 
gine of forty-horse power. The weight of air blown into the 
furnace daily, is greater than that of all other materials. The 
blowing engine, of course blows cold air, which by the hot- 
blast stove is heated to at least 1,000 degrees before going into 
the furnace, thus saving at least one and a half tons of coal 
per ton of iron, over the old way. The blowing engine is 
making by Robinson, Rae k Co., of Pittsburgh ; the cast iron 
work aside from engine, by E. P. Allis k Co., of Milwaukee. 
This work would do credit to the oldest shop in the country^ 
The sheet iron and boiler work by R. Davis, of Milwaukee ; 
the iron roofs by F. Letz k Son, of Chicago. Much of the 
work is done in the shops of the company at Bay View. To 
use the pig iron to be made next year, a much larger puddle 
mill will be necessary, the walls of which are now up. This 
building is 166x82 feet, and will contain sixteen new pud¬ 
dling furnaces and will be entirely fire proof. The company 
have a machine shop, where all repairs to machinery and roll 
turning are done. Over this is the carpenter and pattern 
shop, containing wood-working machinery, patterns, etc. In 
rear of this, on the first floor, is the blacksmith shop, supplied 
with one of Morrison’s steam hammers. All machinery in 
this building is driven by a twenty-horse power engine, built 
by the Bay State Manufacturing Company of Milwaukee.
