The Mineral Region.

The following extracts from recent letters from
Lake Superior have been obtained by US for publ
cation and their authenticity and the dsinterested
ness of the writers may be relied nn. AT the same
time we will repeat our caution against rash and
ex,ravagant specuations in Mining property and
enterprises The very fact that the Mineral region
of Lake Superior is surprising the most sanguine
expectations will tend to fill the market with reams
of certificates of Stock in Mining Companies not
worth the paper wasted in printing them. If you
choose TO become interested in Mining operations,
know who yoa trust and what you buy.
