week that work would begin at
once on the Chicago Boston
- was the most important min
ing news in many weeks. 1t is al
ways a matter Of great public inter-
est in mining district when strong
financial organization undertakes the
development of new mine, for like
all things earthly, there is limit TO
the life of all mines, and If the dis
trict is to maintain prosperous ex-
istence, new mines must be found be-
fore the old are exhausted. This does
not imply that any of the mines OF
the Coeur dAlene district are neaG-
ing the end of their bounty; on the
contrary most of them are still in the
heyday Of wealth production and all
are assured of many years of, profit
able life Nevertheless an enterprise
that promises to bring a new produc-
er into existence is always most well
come, for it means a substantial addl-
ton to the local payroll, diverts addl-
tjonal cash into the channels of trade,
and gives reinsurance of permanence
and stability to the great industry up
on which all depend for support. Thus
the announcement that John A. Percl-
val and his eastern associates would
begin carrying out an extensive plan
of development on the Chicago Bos-
ton, coming at a time when most OF
tho mines Of the district are shut
down through the strike, was most
welcome news, the best news in many
weeks.
Looks Like Making Of Great Mine.
In spite of the fact that highbroWs
of the mining profession have turned
down this particular section, and IN
fact that entire section on the south
side of the river, from Osburn to the
Montana line, with the result that
only on rare occasions has large cap
ital been induced to enter there ana
then only in a half-hearted manner,
the Miner ventures to express great
confidence in the success of the chi
cage Boston enterprise. The history
of mining in the west is fun Qf sxam-
pies of great mines being opened
where experts claimed that ore could
not exist. This paper would be the
last to deprecate expert opinion In
mining, but the fact remains that
were it not for men, prospectors and
operators alike, who refused to be
governed by it, the wealth of many
great mines would still be buried In
the depths Of the mountains. How
ever. Mr.. Percival has not disregard
ed expert opinion in taking over the
Chicago Boston. Several biologists
of unauestioned ability have recently
made a thorough examination of the
property and only one Of whom made
an adverse report.
