reaching the soulherly coast, aud thus,
he said. we find as we approach the
foot aud The head Of the Lake, where
these causes sease to operate, The mean
temperature becomes much lessened
and the climate more rigorous. The
effect Of this upon vegetation, is very
apparent, for little inland from that
portion Of The south coast bounding
the wider portion Of the Lake. we find
many Of the delicate animal plants,
thai would be DESTROYED by the slight
est frosis. growing with all The vigor
that we find them in parallels of laii-
tude Al ; TO AZ but as we approach,
tie head or the foot Of the Lake
these disappear entirely, and those
plants indicative Of higher latitude
make their appearance.
In approaching the deposiies If NM
erals. he said. that much of the disiric,
which he had alluded to upon the
south shore ofLake Superior, rs of little
value in an agricultural point of view,
he hoped at some day 10 see il render
ell of value for its hidden treasury of
minerals He began by referring 10 a
region Of country which constitutes a
slight depression in the Upper PENN
sula, and extending in somherly di-
rec,ion from near the sources of Two
Hearted river of Lake Superior. to-
wards the north of Monislique river
of Lake Michigan. Here is tract of
country easily accessible, Astounding in
beds of bog iron ore Of superior
quality and appearing in workable
beds, at short intervals over an area Of
several hundred square mites. He re-
CARDS this as a source Of great wealth
and its development as closely con-
necied with the completion of the
great work under consideration. After
referring to the beautiful groves Of ma
pie timber, crossing and surrounding
this iron district, and The ease with
which i, could he made into coal Tor
the reduction oil the ores, he proceed
ed to say, that his attention was early
called to the peculiar continuity OF a
range of hill commencing upon the
coast Of Lake superior. lew miles
west from Chocolate river, extending
in south westerly direction across the
Upper Peninsula, and thence across
the Menominee aud sons Of The up
per forks Of the Wisconsin river, con-
lnuing in the direction of the Blue
Mounds Of Wisconsin. He was now
well satisfied tina, the uplift Of this
range Of hills, was due to the same
cause which had given rise to the dis
iurbance of the rocks in the mineral
district of Wisconsin,, and that was in
fact, the termination OF the mineral
d,s,ricI Of that Territory upon Lake
Superior. This range Of hills for a
distance of some eighty miles from
Lake Superior, is made up of altered
sandstone and mc,amorphic rocks, ira
versed by heavy dykes of trap, and
associated with these The sdlphureis OF
lead and suIphuret and pyriious cop
per. appear in narrow veins, associated
in manner resembling that observed
at some points in Wisconsin. These
associated minerals have not been no
,iced in any other portions Of this re-
gion of country, and he said that al
though he had examined this range
with as much care as circumstances
would allow, and made large col!ec-
ton Of these lead and copper ores, the
ir:egularity and nsrrowness oil the
veins, added to many obstacles which
he had net in the examination, had
rendered i, impossible TO determine
much Of The prospective value oil The
district. but upor the whole he looked
upon Il unfavorably, though as showing
the lower rocks that have been inllm-
siely connected with the heavy de-
posts Of lead farther south, il possesses
deep interest as matter oil scientific
investigation.
