Aluminium at fifteen cents a poundi
Such a condition of affairs would revo-
lutiopize a hundred of the useful arts
and make the Twentieth century an age
of aluminium, just as the Nineteenth mas
been an age of iron. j. M. H1rsch,
German chemist of Chicago, says ne has
discovered process by which ne can
extract the aluminium from common
CLAY at a cost of fifteen cents or less tor
each pound. If Mr.. Hirsch is right, then
his secret is worth many millions OF dol
lars.
Aluminium is the perfect metal. 1t Is
SO plentiful that it composes the metalilc
base of the earths crust. The soil under
our feet is full of it. 1t is as bright as
silver and it weighs only one-foulth as
much-in fact, it is only two and one
half times as heavy as water. 1t Is both
malleable and ductile, and may be drawn
into fine wires or beaten into sheets as
thin as paper. Water does not corrode
it. It does not tarnish or change color
when long exposed to the air. 1t is not
affected by any acid except hydrochlorlc.
1t is superior in lightness, strength and
resistance to destructive forces to any
other metal. And yet it is scarcely
known to the general public and is used
very little. Why? Because it costs too
much to extract the metal from the tena
cious grasp of the clay which contains it.
IMPORTANCE OF THE DISCOVERY.
At So a pound aluminium is found
only in the chemical laboratories rs a
sort of curiosity. At fifteen cents
pound its uses would be endless. 1t
would be employed in the manufacture
of thousand of articles-from collar
buttons up to freight cars. Since alu-
minum was discovered, fifty years ago,
the one great problem in chemistry has
been to cheaper the process of separating
it from clay. If the Chicago chemist
has solved this problem the most ex-
travagant statement will scarcely ex-
aggerate the far reaching results of hi.
achievement.
Professor Joseph NJ Hirsch is not a
moneyless adventurer and he is not
proclaiming the Importance of his dis
covery; in fact, he is very reticent in re-
gard to the matter. He is not after
subscriptions of stock, for the entire
stock of the company which he has
organized has been quietly taken up by
few capitalists, except the great slice
Of 81 100000 retained by the discoverer
of the process.
Professor Hirsch, studious, pleasant
faced, specialized German of 40. was
found at his office.

"Well, to freight cars, for instance

steel, and the metal can be used for
