There Source of Fluxing Ore,
Says Expert.

The importance of the Dolly Warden
district OF Nevada as a source of flux-
ing ores has apparently been over
looked by the smelling interests of Salt
Lake City. in the opinion of George A.
Henry, a mining man of large expert
ence. who has been making a close
study OF a large portion Of the Deep

in the past are becoming exhausted.
