Steel Direct From Ore.

How John Potter, the Los Angeles
inventor, has found way to produce
$50 pound ingot Of pure steel without
the use of coke or coal in either the
Bessemer or open hearth process is de-
scribed by Harry FL. Dunn in the Tech
meal World Magazine. POtter's Idea
| was that of an oil blast furnace. In
the center of his furnace he piles the Z
crude iron ore and a mixture Of lime
and asphaltum in a certain proportion,
which Is the secret of the process
Then a Jet of crude oil is turned on
and lighted. With heat of 5000 de-
grees the whole mass is fluxed and the
resultant steel flows down into a lake
in the bottom, later to be drawn Off
into puddles and cooled, or the m often
steel can be run directly into molds,
thus saving one costly process under
the old methods. The loss in Potter's
process is only about 6 per cent, while
In the existing methods the loss is
from 6 to per cent. This means a
saving Of millions. Potter invented
also the blast burner he uses. and that,
too, LIS secret. This inventor began
as greaser boy in steel plant at Z.
Johnstown, Pa, and worked up until
he became manager of the Carnegie
plant at Homestead. At Chicago he
assisted in perfecting the first rail ia

Hart Cancer Cure Demonstrated.
A public demonstration of the new
"fulguration" treatment for cancer has
been made at Paris by DR.. Hart in the
presence Of thirty prominent surgeons
Of all nations. DR.. Hart, whose home
is at Marseilles, has used the treatment
for eighteen months, and In IS per
cent Of the cases the patients remain
cured. BY means Of Gaiffe's electric
transformer he sends through an in
sulated probe an electric spark FIVE
inches long. This is applied with a
fulgurating or flashing effect on the
cancerous growth, thus destroying all
the diseased tissues. Then the spark
is used In lieu of knife to volatilize
the affected part. The wound Is wash
ed in water and antiseptic.
To North Pole by Bears.
Captain Road Amundsen, who some
years ago successfully navigated the
northwest passage in the little sloop
Gjoa, and who is now visiting the
United States. is preparing for an ex-
petition to the north pole in which he
expects to use polar bears as beasts of
burden. He has two polar cubs now in
training for this purpose. The captain
believes that bears are peculiarly fitted
for this service by reason Of their great
strength and their absolute immunity
to the inclemency of the arctic wealth
er. He expects to go into the polar
regions provisioned and equipped for"
a stay Of five or six years il necessary. i.
Photosraphine the Invisible.
Workers in the field Of photography
claim that an instrument has been de-
vised which, with the aid of a powerful
microscopic apparatus, can make use Of
ultra violet light to photograph objects
too small to be seen with ordinary,
magnifying devices. The use Of pho
Biography is necessitated by the fact
that ultra violet rays, though they do

sensitized plate or film. Thus the new
process actually employs invisible rays
to reveal invisible objects. A writer in
Harper's Magazine, calling attention to
this process, says that one Of it's ad-
vantages is that by means Of it pro-
toplasm and microscopic animals and
plants may be studied very advanta-
geously while in the living condition.
With visible light protoplasm is so
nearly transparent and homogeneous
that much of it's structure cannot be
seen, while in ultra violet light the va
