was resumed FEBRUARY 10, and has
now advanced to point 45 feet be-
low the sixth level The shaft sta
tion sump on the sixth level of the
McGaw have been completed and the

Jon Prescott pump to be installed
there has been finished The pump
will be put in place at once. The
opening of the ore body from the
McGaw shaft at greater depth is ex-
pected TO give results very favorable
to the future of the Superior & Bos-
ton mine The sinking OF the Great
Eastern Wine from a point 90 feet
below the sixth level was resumed
FEBRUARY is. The raise being put
down from the Great Eastern drift.
1e0 feet east of the Wine, measures
) 45 feet The raise rs feet west of

broken down from these raises forms
part of the smelter shipments.

company will be sufficiently equipped
with power for air drills TO enable
the development work to progress at
a rate comparable in proportion to
that at the Miami Copper company
workings. located to the northeast.
Ten air drill win be in operation
in as many faces. Within the next
two weeks. and if no Unforeseen de
lay occurs in the work of installing
the large compressor and boilers.
Both the compressor and boilers are
on the property. and the foundation
work for their installation is well
under way. Five working faces be-
