attention Of the world, while its mountains OF I'M

More recently exceedingly rich deposits OF silver
have been found and probably worked on the
north shore, near Thunder Bay, while other de-
posts OF the same metal have Just been discovered
the Iron River, in the vicinity Of the Porcupine
Mountains, on the south coast. Reports OF gold
discoveries in the immediate vicinity Of the lake,
st various points about it's westerly end, reach u.s.
with every evidence Of credibility.
But more valuable far than all these is the recent
discovery OF tin ore in the same prolific quantities
and richness that characterize all the deposits OF
shat wonderful country. This discovery, the
latest ana as yet the least developed
of any Of the mineral discoveries OF the
region, promises to be the most important
and valuable because OF the scarcity of the metal
on this Continent and its universal in this age
of the world. There have been several slight
traces Of tan ore found in various localities In the
United States and Mexico; but none Of them have
developed the metal in sufficient quantities to
repay the cost Of mining. Some years ago the
United States government, realizing the value and
Importance of this metal offered a reward OF
100000 for it's discovery in quantities sufficient to
Justify Its mining, and the Canadian authorities
also offered liberal reward for the same object
Both OF these offers, after standing open for years
without accomplishing the desired purpose, we're
subsequently withdrawn. Now American enter.
prise and energy have brought to light what these
large rewards failed to disclose The deposits
which have been so recently discovered are vr-
finally inexhaustibe, and according to the analy-
ses OF the ores that have been made are, like the
other metallic deposits OF the Lake Superior re-
'gion, of unexampled richness.
A few years ago vein Of virgin silver was dis
covered on nearly submerged islet, just Off the
entrance to Thunder Bay, on the north shore of
the lake. This discovery was followed by the
formation Of a company, with ample capital, that
-ls now working az that point OF the most sue
cessiul silver mines In the world This discovery
stimulated the zeal Of explorers, with whom the
whole north shore was soon covered. These en-
tcrprising searchers after hidden wealth soon I'M
earthed other beds of silver along the coast in the
vicinityof Thunder Bay and 100 miles back in the
interior, in the region Of Shebandowan Lake,
brought to light promising beds OF quartz richly
studded with gold. This discovery has remained

The location Of this wonderful and most timely
shore OF the lake, in the province OF Ontario. The
precise point Is about midway between the Saulr
poste Michipicoten Island. The coast in this To-
callty is high, rocky and barren. Clifls OF solid
granite rise IRON the bosom OF the lake to an alti
fude OF 1000 feet, their tops covered with sparse
growth OF FIR and cedar. This rockbound coast is
broken 6y an occasional ravine, through which
some wild mountain streams find precpt0us
course to the grand receiving reservoir. The
mouths OF these streams are usually broad and
deep, furnishing secure and beautiful harbors with
suinclent borders OF lowland for commercial pur-
poses. These lowlands are covered with ever
greens and white birch. A few stray Chippewa
Indians wander through the forests back OF the
lake IN that vicinity, and subsist by trapping
casional traders along the coast. Bears. wolves
and deer abound also in the woods, and abundance
OF water fowl and hsh Of the finest quality are
always TO be found In the lake and estuares The
region is really q wilderness, presenting all the
features OF natural grandeur, beauty and solitude
