PAST YEAR NOT So BAD
FUTURE LOOKS GOOD
BUNKER HILL MANAGER BRIEF
~ DISCUSSES LOCAL MIN
ING SITUATION.

The review issue of the Engineering
and Mining Journal, which has just
been received. contains among other
interesting features brief summary
of the mining operations in the Occur
dAlene district during the year 1914,
together with reassuring statement
regarding the future of the district by
stanly A. Easton, manager of the
Bunker Hill & Sullivan company. HIS
reference to the improved methods Of
recovering lead zinc and silver from
shines through flotatlon speaks well
for the progressive tendencies Of the
operators Of the district. His BRIEF
comment ON the experimental work
that Is being done by the Bunker Hill
company with the view to producing
metallic lead, silver and zinc through
an electro chemical process Is of spe-
cial interest, and the fact that Mr..
Easton regards the results SO far
achieved Of much interest and prom
ise," suggests that the present year
may witness an advancement In the
methods Of ore treatment that will be
little short of revolutionary In their
effect. Mr. Easton's reference to the
favorable conditions that have fol-
lowed deep development, the new pro-
ducers that have appeared during the
year, and his confident prediction for
