COPPER.

| The following article contains much valuable
information in reference to the production and
consumption of copper-not easily obtained By
general readers. We venture the opinion that
| it is from the pen of highly respectable
and scientific gentlemen, resilient in one of our
central counties and many years ago resident
and we believe native of this.
The day of mere stock companies, formed
only for the purpose of selling Stock and plum
tering the unwary has fortunately comedy af-
ter brief duration, and the question of our
ability to produce copper prottably from the
mines of Lake Superior will be fairly tested by
the working companies. That many of them
will be successfully, and some of them emf
nently so, we see no reason to doubt, and how
ever individuals may suffer in the experiment as
is generally the case in all new enterprises, we
think the country is to be greatly benefited
The very limited operations ofthe present sea-
son on Lake Superior have been productive of "a
good deal ofbusiness for Detroit and Cleveland
and we are told their orders for supplies, and
those mostly agricultural are now being filled
in this city to the amount of several thousand
dollars. We saw one in the hands of one
dealer last week for about three thousand dollars
worth of flour, pork, beef butter, &c., &C., for
the winters consumption of one of the compa-
MES on the main shore, and we are told the out
tit of the Isle Royal and Ohio Company's expe-
dition in the spring, for provisions and articles
mostly manufactured here, cost like sum,
and considerable shipments have been made
since.
Should the copper business be as extensive
and advantageous as We think it will be, the
benefit to mechanics, farmers, merchants and
vessel owners will be very considerable.
| If the labor of one THOUSAND or of fifty, thou
sand men can be profitably employed in mining
copper or coal or iron, it will be much better
for them and the public, than ifdevoted to raj
sing wheat for an Over-stocked market.
The greater the diversity of employment in a
community, the more can all classes thrive, and
the wider is the field for the exercise of indvid-
ual genius and industry.-Cleveland Herald.

MEssRs. EDrTORs I'm your paper of the ard
inst, l read with interest an article from your
correspondent ''W," under the head of Cooper
Lake Superior-Cornwalll." AS IA great err
ror exists in the public mini in relation to Cop
per ore in general, think it well worth the
trouble to present some facts CLEANED from stad-
ard works, in addition to those noticed By your
correspondent. We have had somany inflated
statements respecting the richness of Copper
ores found here and there in the United States,
that the impression is becoming general that if
the ore of any mine is not Is to 30 per cent, in
metallic Copper, the mine is mo- worth wor-
king. All the copper heretofore used in the u.
States, is the product of foreign countries.-
In lS44-5 there was imported into THIS country
S73s, 1886 worth of sheet copper and 6, ,225, 30l
worth of pigs and bars OF the former, Eng
land supplied S7SO,7O7, of the latter, $2O6,6i5;
Cuba, 8 5O,752 British West Indies, $35, 49,;
Chill, $797,507; Peru, $5e,l36. The residue
was bro't in small parcels from divers countries
During the same time we exported 1874, 1856
worth of copper. Aggregate of IMPORTS, 3d.

The amount of copper imported into Great
Britain for some years past has not equalled
$1,000 per annum. Great quantities of ore are
imported thither, chiefly from Cobre, Santiago
Chill, Cuba, San Jose Cobre, Copiapo and Aus
trala. These ores are smelted at the great
works in Swansea,
| The British mines alone produce about IL, 900
tons of copper per annum. The principal mines
of these, the Cornwall, produce ores averaging
about per cent. The Swansea and Irish
mines about Is per cent though much less in
quantity.
OF the ores imported and melted at Swansea
from different countries, we find about the fol
lowing average, viz:
Cobre l5fperc. Copiapo 25perc.
