America virtually has made itself inde'

American Chemical Society was told
today.

list, speaking before the dye division
Of the society, said 95 per cent OF the
dyed furs used in this country were
home products and were equal to the
best produced in Europe.
The food color industry in the United
States also was declared on firm
basis in an address by M. c. Balm
bridge of Brooklyn, n. Y. Cut off from
German sources of supply during the
World War, he said, the industry met
the crisi$ and now could boast of
a superior line Of products OF truly
American manufacture.
Smokers Fears Allayed.
Smokers need have no fear of the
effects of chlorine in tobacco, declared
r. b. Carpenter, chief chemist Of the
Virginia Carolina Chemical CO., Rich

had shown that while cigars contain
more chlorine than was generally sup
posed, it. was seldom that the quantity
was sufficient to do serious harm. The
average smoking tobacco, he said,
contains less chlorine than cigars.
Lighter automobiles. greater engine
efficiency and increased mileage was
predicted by Prof. Robert T. Haslam
of the Massachusetts Institute of
Technology as a result of improved
automobile fuels and increasing the
compression CT the gasoline and air
mixture prior to explosion. EXten-
sive chemical researches, he pointed
out, had shown that the tendency to
detonate could be greatly reduced by
the addition of such chemical COM
pounds as aniline, iron carbonyl and
tetraethyl lead.
The action of the ductless glands
and other organs are being studied by
scientists all over the world, de-
apolis mot until we know the exact
physiological relationships of these
organs to the body as a whole, and
to other organs. can we start to
search for their specific chemical
principles or harmones," he said.
Kentucky's Blue Grass.
The fertility of the blue grass re-

orally been supposed since pioneey
days, due wholly to the richness Of

cium, according to DR.. J. S.. Nc

al Station of Lexington. He said re-
cent Investigations had shown that
this area was also comparatively rich
in manganese, copper, zinc, boron,
nickel and cobalt.
The commercial value of latex, the
milk of the tree from which rubber
is derived, was stressed at the crude
rubber symposium.
A new process, in which lateX in
it's milky form is first vulcanized and
then evaporated, reversing the pre-
vious practice, was said by DR.. Philip
Schidrowitz, a leading rubber tech
nologist of England, to be highly i'm
portant in improving the quality of
rubber goods.
This new process, he said, excludes
heat, which tends to destroy fabric.
Industrial application of latex in tire
manufacture was declared by Dr.
SchidrOwitZ to be a notable develop
ment.
In making direct use of latex, he

Amazon region, who since 1886 had
been coating linen with 'milk-white
liquor" with which they also were
making water-tight boots.
Substitutes for Rubber
The possibilities of developing sub.
stituteS for rubber that are uncon-
nected with synthetic rubber was dis
cussed by DR.. Ellwood B. Spear, vice
president Of the Thermatomic Carbon
Co., Pittsburgh.
There is always the possibility"
he said, "of producing new sub
stances, not necessarily similar in
properties to vulcanized rubber which
will replace rubber for various uses
and be superior physically and eco
nomically."
DR.. G. S. NVhitby of McGill Univer-
sity, Montreal, discussing methods of
testing raw rubber, showed that the
resins Of impurities in rubber have
greater effect on the quality of vul-
canized rubber than the rubber it.
