With such iron to be had of American manufacture, why should we use
a rotten English article for car-wheels and boiler-plates, and so
sacrifice the lives of thousands every year? Because, by an unwise
legislation, the foreign article is made a little cheaper to the
American consumer.
There are ten large forges in operation in Michigan, with a capital of
over two millions of dollars; and the shipments of ore from Marquette
in 1859 were over 75,000 tons. The country back of Marquette is full
of mountains of iron ore, yielding 60 or 70 per cent, of pure metal,
sufficient to supply the world for ages.
Traces have been found, through the whole of this copper-region, of a
rude species of mining practised here long before it became known to the
whites. The existing races of Indians had not even a tradition by whom
it was done; and the excavations were unknown to them, until pointed out
by the white man. Messrs. Foster and Whitney, in their survey of the
copper-lands, found a pine-stump ten feet in circumference, which must
have grown, flourished, and died since the mound of earth upon which it
stood was thrown out. Mr. Knapp discovered, in 1848, a deserted mine or
excavation, in which, under eighteen feet of rubbish, he found a mass
of native copper weighing over six tons, resting on billets of oak
supported by sleepers of the same material. The ancient miners had
evidently raised the mass about five feet, and then abandoned it. Around
it, among the accumulation of rubbish, were found a large number of
stone hammers, and some copper chisels, but no utensils of iron. In some
instances, explorers have been led to select valuable mining-sites by
the abundance of these stone hammers found about the ground. Traces
of tumuli have also been found in these regions, which would seem
to indicate some connection between these ancient miners and the
mound-builders of the Mississippi Valley,--especially as in those
western mounds copper rings have frequently been found.
The economical value of the Lake fisheries is considerable. The total
catch of white-fish, trout, and pickerel, the only kinds which are
packed, to any extent, was estimated for 1859 at 110,000 barrels,
worth about $880,000. These find a market through the States of Ohio,
Kentucky, Indiana, and Illinois; besides a large quantity which are
consumed in a fresh state, in the Lake cities and towns.
