OF such great interest that scientists
from all parts Of the world have come
to study them. With myself these
men have been deeply fascinated by
this thrilling chapter OF the domeeti-
cation Of a wild plant-a thing not
likely to be seen more than once IN Il
lifetime.
But now all has been accomplished
growing rows Of shrubs containing
rubber which are evenly matured. It
is now believed that they arc ripe.
The determination OF the exact har-
vest time has not been made, but II
is near at hand. 1t is safe to say that
an immense achievement is about to
be announced.
''Guayule rubber is not exactly like
that known as Para II has special
usefulness in the manufacture Of most
rubber articles. including tires. This
cultivation Of guayule will be OF
mighty moment to the industry. and
will tend greatly 70 extend the use

Rubber, orce il is produced IN
quantities sufficient. will be available

In surplus because its previous scar
city has limited its uses. Soon new
uses will make IL scarce again. The
same is true OF rubber. II is safe to
say Mt present that neither the motor
industry nor any other will suffer in
the future for the lack Of it. but that

Need we actually fear exhaustion
Of any really essential natural mate
rial?" l asked DR.. MacDougal.
Il think not" he answered. "The
| study of natures ways and human
effort shows that when mans sup
plies Of raw materials run low need
| and rising prices loose hundreds OF
inquiring spirits to the study Of ways
and means for the increase OF the
supply or for the satisfaction Of the
needs with other material. Such
state Of affairs now exists with re-
gard to the liquid fuel supply"
Then you do not fear exhaustion
for that, either?" Inquired.
'I do not fear It in the least. The
number OF trained scientists now en-
gagged in researches designed to keep
at hand a full supply OF fuel for the
| worlds motor vehicles would amaze
the iayman.
The general thought that should
wish to convey to the public is that
the fear that civilized and developed
lens is a pessimism not In the least
justified by any probability. With
the facilities for research now avail
able. 1t is impossible for me to be-
lieve that mankind can be halted in
his quick advance by any problem.
"If our trained scientists should
find themselves in the, TO me. un-
thinkable extremity Of being unable
! to unlock the necessary stores Of en-
| ergy for heat and light, for instance
/ in other words, IL coal and Oil should
fail us, and IL we could not utilize
electricity supplied by our vast unde-
ve!oped hydraulic powers-we stin
have streaming down on US every day
unlimited power wealth in form of
sunlight. the capture and utilization
of which is not to be regarded as
| task impossible to human ingenuity.
II would be the last man In the
world to argue against conservation
of natural resources. Nothing can
justify their waste as We unlock them.
But at the same time have COM
pIete confidence in the ability OF ma
ture to supply US in future. and in
creasingly in accordance with the de-
mands created by our own develop
ment, as she has done in the past"
