YOUNG SEES AIR
GAINS AS u. S. AID
All Bushes to Be Stimulated
by Aeronautic Growth,
He Predicts.

All branches of American business
will be stimulated and increased by the
rapid development and utilization of air
transportation, it is predicted by Maj.
Clarence M. Young, Assistant Secretary
of Commerce, in the annual report of
the aeronautics branch of the Depart
fnent of Commerce, made public today.
There has been continued growth during
the past year in all branches of Ameri-
can aeronautics he said.
Trade areas now served directly by
air routes in this country contain
approximately 100000 people, or
virtually all of the country'S population,
Mai. Young said, and by next Summer
practically all of the larger centers OF
population and many of the inter-
rnediate-sized cities will be connected
directly by air transport routes.
1t is generally conceded throughout
the aeronautical industry, Maj. Young
reported, that the Department of Com
merce is contributing materially to the
advancement of civil aeronautics, to the
creation of powerful reserve of aerial
defense for use in time of war and TO
the development of Nationwide net
work of air transport for use in time OF
peace.
Employment to Increase.
This advancement, he said, will pro-
vide employment for a continually in
creasing percentage of the population;
will speed the movement of men, money,
mail and merchandise, and will de-
crease the cost of distribution and
thereby increase the purchasing power
Of the consumers dollar. BY aiding in
many ways to speed of commerce and
industry the further development OF air
transportation will lower the cost of
transacting business materially through
out the Nation.
There have been many notable adj
vances in aviation during the year, Maj:
Young said, aside from the growth OF
air transportation.
The airplane has been greatly I'M
proved. Into it has been built much
of the inherent stability hoped for and
promised by aeronautical engineers Tor
many years. What is more important,
this stability has been achieved without
the sacrifice of maneuverability.
Wheels Replace Tail Skids.
The increasing number of multi
motored planes, the greater use of
metal propellers, substitution of tail
wheels for skids, combined with the
use of wheel brakes; the increased use
of metal framework in wings and fusel-
ages, development of the Diesel air.
plane engine and attainment of greater
speeds in nearly all types of CONNER
cial aircraft we're cited by the civil
aeronautics chief as among the most
striking features of the years develop
ment.
Until recently" the report continued,
"the large supply of engines left over
from the war materially retarded
Americas development of aircraft en-
gines. Now, however, this supply is
virtually exhausted and large numbers
of new engines are being developed.
Exhaust manifoldS are receiving con-
siderable attention in an effort to reduce
noise as well as carry exhaust gases
clear of the passenger compartment.
Through improved installation of
intake and exhaust manifolds, with
mandatory utilization of fire walls and
the elimination of air-pressure fuel-fed
systems, the possible rush of fire has
become almost negligible"
