great deal of new Information on
Arizona's vast mineral deposits.
These deposits are of great scienti-
tic interest not only from the variety
and beauty of the crystaliZations pre-
scented, but containing as they do,
clements of considerable rarity, be-
cause the chemical and geological
conditions which have given rise to
them demand investigation.

Dunkirk Jumped"
As the clock was on the stroke of

with the thermometer at the freezing
point, one Of the owners of the Dun
kirk mine, name Of Beasley, was
rudely awakened by the entrance of
two masked men into his cabin at
the mine, states the Parker Post He
was ordered to dress, gather his per

Beasley had arrived in the afternoon
of the same day he was told TO get

starting the anDual assessment work

ground But he arrived too late, for
il appears that some covetous persons
had their eyes on the claims and
upon arriving at the property and
finding it in possession of someone
else, they decided to make him git

rived at Nidel last Saturday and re-
lated his experience. News OF the

through Amos B. Atkinson. who
rode in the same rig with Beasley
the previous day as far as his
claims in that vicinity.

Lost Art" of Temperinq Copper

Then comparison of the two

Then across the minds of the scien-

of MeXico the copper was already
for them; the cobalt and
the nickel fused with the copper,
when heated in their primitive fur
naces. and the result was a grade of
alloy. which. when heated and sharp
ened, gave an edge which would cut
like steel. The Indians knew moth
ing of the art OF tempering the
metal themselves. and could not have
removed the cobalt and the nickel
from their ores. even had they so
desired.
