The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1915-04-29

these three days we cut back into the
walls of the drifts at different points
from one to two feet. In other places
we put in shots that extended into
the walls as far as the cuts. The sam
pies taken from the back end of these
cuts and from the bottom of the shots
returned only So to SO in gold and in
all cases this gold was uniform in its

and | notified the head assistant OF
one of the other engineers who was
examining the property, well-known
professor in one Of the schools Of min
mes, that | had become suspicious of
sailing and | would advise him TO re-
sample the property. Word came back
from the professor that every care had
been taken and he was personally sa-
tished with the samples he had already
made. To test the matter further, !
determined upon a mlllrun upon the
property-there being mill on IL

we sampled each place as it was blast
ed, sampled the ore as 1t was hoisted
in the buckets sampled 1t as 1t went
through the crusher and from the self
feeders into the batteries, and samp-
led the failing. With all of this somp-
ling, there was little chance for decep-
ton and the mill-run showed that the
gold contents of the ore were very
much lower than had been represented
and much too low to pay We paid no
attention to the bullion.
Deathbed Confession.
] Years afterWard, a report reached
lme that when tie manager Of the pro
Iperty was on his death bed ne told
how the sailing was done and that it
cost several thousand dollars Per-
Isonally, | have been puzzled to know
and can imagine no other way than
the use of a shotgun. Even with this

ore itself was of Clayey character and
that the gold would readily attach it.

But sailing is not the only means
of deception in mining. An interest
