The smelter proper is a structure 40
feet long by 225 feet wide. covering two
and a half acres. 1t is constructed of
iron and is absolutely fire proof. There
are in the building upwards of 300 tons
of iron and about 800 windows will sup
ply light for the many workmen who
will be engaged beneath its ample roof.
This smelter is thoroughly equipped with
all the machinery and appliances neces-
sary for the treatment of 600 tons of ore
daily and it can be increased to 1000
tons whenever desired, and this increase
will be made as oon as possible.
THE SMELLING PROCESS.
