Aluminium has only been on the
market In = commercial way for about
4 yean In that time the applications
10 which this metal can be cconom-
ically put have been found 70 be 70
numerous that the Press predicts its
introduction will mark = great step Ia

Aluminium ut Is cents per pound-and
II viii surely reach that price-will
take the place Of iron and steel in
many important lines Of manufacture
Its adaptibtlity TO ship-buildiog be-
comes 1t once apparent The use OF
aluminium for this purpose would
change the mighty black racers OF the
Atlantic Into bright silver vessels,
which would inspire tho marine posts
to flights Of hitherto unhcsrd-of fancy
in describing how lightly the silver
ship rode the blue billowa" Serious

racers In tho course Of time will be
Constructed OF aluminium
It's chief advantage 10 its ligh tuesa
At present one Of the great difficulties

power sufficient 10 obtain more than
twenty miles an hour It has been
estimated that II an Atlantic liner
we're built Of aluminium, or that the
weight Of the material out OF which
hips are constructed be reduced by
