Dr. onBpNEn'B EXPLORATIONS,
Dr.. orcdner is native OF Germany, an OK
cellent scholar, and fine goologist. He WAS on1-
ployed by tho Portage Lake Canal. Company to
assist Professor Pumpolly III examining tho
Company'c lands In tho Menomonoo iron-rogion:
This corporation waa formed for tho purpose OF
cutting ehip-canal through tho narrow muck OF
land at the west end OF Portage Lake, by which
tedious detour Of 160 miles about Keweenaw
Peninsula tB avoided: To aasist In tho work,
two land-granta wero mado by Congress. The
aecond grant was Of loo, 900 aoros, which tho
Company located In tho iron-rogion Of tho Mo-
nomonoe. Ten square miles Of 1t arc iron-lands,
$4,000 acres Of 1t are covered with hardwood
timber. and tho rest Is coverad with pine. THO
ostonsiblo. object Of this scientific exploration
Was to prove tho existence Of workable beds Of
iron-oro." The result Of. tho researches was
emiuontly successful, and nc. give It, oonaenalng
ns much rs possible.

{about 10, miles from tho river). This section
IL crossed by q belt Of iron-oro Of more than
ono mile in width. Tho ores form preolpitous
RIDGE rising abruptly to height of about zoo
or ESQ feet. They appear every 8hero On tho sur"
faoe, exhibiting immense outorops for the "hole
length Of the iron-belt. Tho ores aro hemattcs
cred ores, and vary in tho percentage from loan
quartzose ores to nearly pure massive hematitic
ores, which will produce 66 per cont Of pig
iron,-70 per cont boing the highest possible
percentage Of Iron In chemically pure hematite.
