for so-called military minerals, which.
however. have their daily services in
the multitudinous activities OF peace
We couldn't send troops, munitions
and food abroad and use the same
ships for bringing home foreign min
erals. We had to develop sources of
supply here. one Of the most impor-
tant OF these minerals was manganese,
essential to the hardening of steel.
This situation was met by the de-
velopment of new deposits OF high
grade ore in the United States and
by devis!ng ways Of utilizing efficiently
low grade ores which the steel MAX
ers in the past would not touch. This
was one of the achievements of the
meteorological divisions of the bureau.
Further, new mines of other minerals
have been discovered and opened up.

prove permanent additions to native
industry and to that extent make us
less dependent upon alien resources.
Nucleus of Gas Service.
When the Bureau OF Mines origi-
naly essayed to spread the gospel of
safety first among our coal fields il
was necessary to send to Europe for
suitable oxygen rescue apparatus
Since then the bureaus technicists
have deI e!oped an equipment OF their
own which is, far superior to all
| Others. Because OF this experience,
the Bureau of Mines was able TO PEE
scribe the outfits needed for our SOL
diers in contendinE with the poison
gases of the foe, Again, the peace
results OF the work in behalf of the
gas masks for the army will have its
reflex in all industries where CANCER
GUS fumes prevail or occur on occa-
sions. We are tod that the same
scientists Of the bureau, owing to their
familiarity with poisonous gases. he
came the nucleus of that organization
OF 100 chemists which constituted
the Gas Warfare Service.
y striking example of the peace time
| gain through war time research Is the
use developed by the bureaus mining
, experts for certain sound detecting
instruments. i. e., the geophone and the
I microphone. These made II possible
! both to locate the hidden positions of
! the enemies batteries OF artillery and
! to detect the foes mining and counter
mining operations under ground. AS a
reflex of these military services the
; bureau will henceforth supply each
mine rescue car with similar sensitive
| listening apparatus. In the past many
! miners have lost their lives when en-
/ tombed by falling debris because they
could not make their positions known
even though they raped or struck
desperately upon the enveloping rock.
| Now the resCuers can locate sounds of
I this sort and know just where 10 direct

Potash Industry Is Born.
Most of us are familiar with the

/ Bureau of Mines in discovering ways
to obtain the much needed potash for
