Twenty-Five claims have been bonded
near Jerome and the money IS now in
the bank for first payment. John
Burkes, who managed the deal. says
five big deals have gone through in the
past week, but for certain reasons the
particulars will be held back for some
days.-Prescott Courier.
In a. lecture at Detroit a few even
ings ago Prof. Trippler, the liquid air
man, announced a discovery recently
made in connection with his work
which is destined to prove of great
value to the mechanical world, being
no less than a process by which cop
per can be tempered by the use of
liquid air Steel is tempered by heat
ing, and then cooling, but the process
with copper. as announced, is just the
reverse. The metal is first subjected
to a bath in liquid air at a temperature
of 312 degrees below zero-a degree of
cold that it is almost impossible for
one to imagine-and is then thrust i'm
mediately into a furnace heated to a
thousand degrees above, and in this
way can be made hard enough to hold
an edge" The value of this discovery
will be very great, for copper, when
it can be given a little temper" is the
best and most serviceabie of all metals
for every kind of machine bearings

Reports from the mines throughout
the Warren district are most encouraS-
ing. Work is being pushed on them all
and some are developing into wonder
full properties.-Bisbee Orb.
Recorder w. I. Johnson is busy these
days recording the affidavits of the
happy miners who have completed
their assessment work for 1899. Many
affidavits have come in, but many more
are due. There are still twenty-one
days left in the year, and if a man
hustles he can do lots of work in
twenty-one days.-Prescott Prospect.
It is reported that Benson is soon to
have a smelter for the reduction OF
rich ores taken out Whereabouts The
prospect for the erecting of smelling
plant at Tucson within a few months
is quite encouraging. The process Oh
operating a smelter by the use of crude
petroleum instead of coke as 1uei
promises to be generally adopted in the
future if the claims made by the Oil
Fuel Saving company of San Francisco
are sustained. This company is in
communication with ]. Bernstein OIL
this place regarding the matter of con-
structing a smelter here in which will
be adopted their invention for using
crude oil instead of coke. They claim
that by their method the most rebel
Iious low grade ores can be reduced at
q profit-Tucson Citizen.
Mr. Clark, the freighter, left yester-
day to look over the roads from Kirk
land to Yarnell also from Congress
Junction to the Yarnell mine, with a
view to bidding on hauling seven hun
dred tons of machinery and pipe for
the Octave mining company; the pipe,
it is said, will be at Kirkland station
within twenty days. A forty stamp
mill is part of the machinery to be
hauled; the stamps of this mill weigh
1850 pounds each and the mill has a
guaranteed capacity of 125 tons a day.
There is also in this lot of machinery
to be hauled to the company's proper
ties in Weaver district, complete ma
chine shop and a foundry.-Prescott
Courier.
w. H. Ferguson, who knows all
about the Ridenour copper mines in the
Grand canyon, says they have devel-
oped into a veritable bonanza and are
worth not less than one million dollars.
