Now, from my long experience in the
various b. anches connected with mining
business, and from frequent observations
in my travels, as well as tracing the min
eral veins to great depths, both in Europe,
America and in the Copper Mines OF the
West Indies, have had an opportunity Of

men, which enables me to form more cor
rect opinion Of the geological formation OF
veins, and of the earth where these min
eral veins are found, than if had gained
my information from theory alone, aud
the most candid explanation will likewise
be af rded on every point connected with
the undertaking, from which a very largo
amount of profit on the sum employed is
certain to be realized. From the perma-
nency, regularity and richness of the ore
at so small depth, and the facilities con-
nected with this mine brings me 10 this

Que of the greatest discoveries ever made
in North Anne RIGA; and when a compa ra-
tive estimate is given Of the outlay and
income Of this mine, compared with the
royal Cabra Copper Mines of Cuba, twelve
miles from ST. Jago de Cuba, it will be
seen, that these mines do not surpass it.,
neither in the external appearance nor
richness at the depth we a'c now at, in
she Consolidated Copper Mine.
Any communication, giving rea name
