Reclaimed rubber, a valuable sub
stitute for new rubber and playing
an important part In conserving the
world supply, will be dealt with, by
Dr. L. E. "Weber of Boston, under the
title, "The Present and Future of Re
claimed Rubber."
Talk Upon Raw Rubber.
W. B. Wlegand, New York physi
cist, will discuss from a critical point
of view the physical properties of raw
rubber and of vulcanized rubber in a
paper on "A Comparison of the Phvs
lcal Properties of Raw Rubber with
Those of Compounded Vulcanized
Rubber."
"There always is the possibility of
producing new substances, not neces
sary similar in properties to vulcan
ized rubber, which will replace rub
ber for various uses and be superior
physically and economically,” the so
ciety's statement continued. "This
suggestive topic of alternative ma
terials for rubber is to be presented
by Dr. E. B. Spear of Pittsburgh and
will doubtless offer an entirely new
point of view to many.
"With rubber now an indispensable
material in industry and daily life, it
is of interest to survey its economic
status, the present lack of alterna
tive materials and the economic ad
vantages of a native supplv. This
subject will be discussed by Dr. A. D.
Little of Cambridge, Mass.
