These great depths diminish the
chance of reaching il with ordi-
nary depth bombs.
Also the crafty NaziS are
using a submarine engine which
eliminates electrical batteries.

On the surface they use a
Diesel motor and below they
operate on hydrogen and
oxygen mixture. This assures
them greater Security-from de-
lection.
The Hitleritcs also have come
up lately with new type of

posed to break through the

These few factors are enough
in themselves to make the ship

only within the last month or
so.

south China and concentrating
in three areas near the Russian
frontier. Their forces in Man

weeks Mechanical equipment
has also been ~moved to these
two districts.
A similar strengthening of the
Jap garriSons in Outer Mongo-
Liza also has been noticed. The
force in this latter area obVi-
ouSly threatens the Lake Baikal
area of Siberia and the Trans
Siberian Railroad.
The Japs would have no great

THOSE three south China sea-

troops recently recaptured, are
of little practical use. The Jap
navy and air force control the
sea and. in effect. maintain a
blockade through which Our aid

Thc new ground gained by the
Chinese is valuable chiefly for
air bases from which our air
force eventually can reach Toxic
