EILESsBURa, Nov. 15.-fSpecial. The
first discovery of this metal dates back TO
1927 by Deville, a professor of and lecturer
on chemistry at La Sorbonne, France.
It's range of value was but little known
at this early period. 1t had aroused
curiosity in other mems minds, so
much SO that other chemists began to ex-
pertinent with various methods TO produce
il. Aluminium Is a white metal, closely
approaching silver in color, and is
extracted from clay, corrundum, baux-
lite and other materials by smels-
ing and electricity. From 1927 to the
present time great improvements have
been made in the methods of its manu-.
facture, each succeeding ono produce
ing it at . less cost than its
predecessor. and in larger guam
tity. Scientists estimate the earth's
crust to contain Isl per cent. of alumni
mum and $40 per cent. of iron. This
guarantees an abundant supply. Alumi-
mum obtained its name from its oxide,
alumina, this being the base of alum. and
as oxygen and silicon are also component
parts of aluminium, these are separated to
preoipitate it as a metal

castings are also improved by being
made tougher. free from sponginess and
lighter without iessening the strength.
