Il If the experiment Of Provisional Government
results in the establishment Of law and erer after
the arrival Of the large military force already Of.
dered to our frontier, we may expect silver min
ing to receive great impetus. New companies
will be formed, aad thousands will invest their
means in enterprises calculated BY sanguine agents
suddenly to enrich their owners. Many viii Be
successful, while others will fail, and though The
country abounds in mineral wealth Of untold rich,
ness, it is only by good management, favorable 10.
cation for wood and water, and proper machinery
and tools, that mining can be made profitable.
There is no business which requires closer at
tenton, better calculation and more careful snpar
intandence than silver mining, Scientific and prac.
tical men, well acquainted with the manipulation
and metalurgieal treatment OF ores are iHdispans-
able, and it 10 requisite that the superintendent
should give his personal attention to the general
economy Of the concern, that every depar rtH5eEtt
may be carried on in profitable and expeditions
manner. No company should anticipate very
speedy returns from their investment. To epen d
mine properly requires time. often experiment.,
and always hard work, A mine whose ore smells
readily and where the mining j. easy, ought with
skfu management, to pay within few months
after the arrival OF the machinery, from which
should date the commencement Of work. Tools
