Among the 40 or more new mining
companies organized within the past
six months to explore and develop
copper properties in Butte about a
dozen of them are active in that di-
rection, and have good prospects of de-
veloping new producing mines. The
Butte-Milwaukee Copper company ex.
poets to begin mining on the Pollock
within month or six weeks. The
Pollock is developed property and
has yielded lot of good ore in the
past, and the company has four other
claims on the same vein. They are the

ence and Stonewall, and for 1000 feet
the company owns ground on the Pol
lock vein. All the claims are patented
and paid for by the company. In ad.
dition to the Butte property the CON-
pany owns seven claims in the Argen.

being made into briquettes together

copper. These products are made up

A jet OF burning oxygen from blow
pipe is now successfully employed to
cut sheet iron, iron tubes and small
bars. The cut made is almost as
w.
In the earlier experiments difficulty
was encountered in clearing the cut of
liquid metal and in preventing the
spread of the melting effect beyond
the borders of the cut. In the process
as now practiced two blow pipes are
employed. The first has an ordinary
oxhydrogen flame, which heats the iron
to redness at the place where the cut
is to be made. This is followed i'm
mediately by the second Jet, compos-
ed of pure oxygen, which instantly
burns the metal without melting. The
liquidized iron is blown swiftly from
the assure, SO that there is no serious
spreading of the heat to the surround
ing parts.
The Black Hills country is on the
verge of great boom in copper, says
the Mining World. For many years it
has been we'll known that copper exist
ed in various parts of the hills. Sew.

city commenced operating the Blue
Lead property near Sheridan, s. D.
