PORTION OF ONE OF THE BIG OPEN-PIT MINES ON THE
MINNESOTA RANGES
"Even if we have furnaces as large as yours," once
declared a manager for Krupps, "even if we have your machinery
and your skill and our organization, and coal as plentiful as
yours, we haven't your ore." And that is one of the reasons
why the United States was able to produce more than half of the
world's pig iron last year. Most of the ore is scooped up by steam-shovels,
like sand.
