REMARKABLE MACHINERY USED IN

THE number and complexity of the
mechanisms to be found in a modern

who visit such a place for the first time. The

old-fashioned methods of hand-
ling material have been super-
seded by machinery. The
dominant word in the steel works of to-day is
speed. Managers for ever cry out, “ Faster,
faster,” and the engineer racks his brains to
respond. A glance at the high-speed and almost
automatic machinery to be seen in the steel
works of to-day convinces one that the engineer
has replied most effectively. Some of the large
works turn out as much as 2,000,000 tons a
(1,408)
year, and the handling of so vast an amount
of material through the works demands some
special types of machines.
In the United States it has been found
necessary to transport the iron ore across the
Great Lakes to the steel manufacturing dis-
tricts of Michigan and Penn-
sylvania ; and as navigation Hulett

the winter months, it becomes necessary to
create large ore reserves during the open
season. This stocking of material near the
quay must be carried out very expeditiously,
so that the boats may be delayed as little as
possible, and so enabled to make a maximum
