NATIONAL MILL READY
START WITHIN A WEEK
ORE IN ALL LEVELS SHOWS I'M.
PRoVEMENT-MlLL is MOST
MODERN IN DISTRICT.

| Everything is now in readiness to
start the National mill with the ex-
ception of a powerful magnet, which
should arrive any day. 1t is therefore
safe to predict that the mill will be
running before another week passes.
The main cause of the delay in start
ing the mill was a broken shaft In
connection with the Symons crusher
the break being due to a piece of steel
passing into the crusher. To guard
against such accidents the belt con-
veyor that delivers the ore passes
around a strongly magnetized pulley
at the mouth of the crusher, which at
tracts the steel and carries 1t around
the pulley under which 1t drops when
it passes beyond the attraction of the
magnet Occasionally when the belt
is heavily loaded with ore a piece of
steel may be lying on top and drop in
to the crusher, being too far removed
to come under the influence of the
magnetized pulley That is what hap
pened when the shaft was broken. To
avoid another accident of that kind
special magnet has been ordered tha'
will be placed just above the belt con-
veyor and close enough to pick up any
steel that may be on top of the ore. i
is this magnet that has not arrived
In all other respects the mill is CO.

500 levels also show an improve
