there are 25,0OO,O0O children in Ameri-
can schools, and we are spending
$4,000, 100000 year to support them.
There are 100000 pupils in public
high schools alone, and over 600 of
these schools have more than 1000
pupils each. This important element
of our population is still waiting to be
served by radio In a new way, never
before possible.
THE best minds from out State uni
versities and colleges and the depart
ments at Washington must be added
to the teaching staff of our high schools
through the development and perfect
ing of chain broadcaSting as a national
educational function. This will result
in elimination Of waste in the present
duplication Of the teaching staff and
reduce rather than increase the annual
educational budget by dispensing with
the inefficient teacher and raising the
standard Of the smaller staff then re-
quired.
This outstanding national service
cannot be financed through public adj
vertising to increase the sale of COM
modities. but must be paid for directly
by the people, as 1t should be. The
needs for new channels of communica-

competition or cooperation.

come in the era ahead, the greatest
educational and cultural institution in
all history Radio is the new sgency
by which alone this is possible"
A new microphone which makes use
of the properties of the air condenser
and is free from diaphragms or other
movable mechanical parts was deScrib-
ed by its inventor, Arthur L. Foley OF
Indiana University.
Discovery that a definite chemical
material is responsible for resistance OF
plants to disease was announced by
three scientists from the University of
Wisconsin, J. c. Walker, X. p Link
and H. r. Angel. In a series OF ex-
perimentS with onions they found that
q substance called protocatechuic acid
was formed to ward off attacks of a
smudge fungus.
Theories of electric transmission in
metals were discussed by Edwin H. Hall
Of Cambridge, Mass.
Brain ana BODY RELATIONS.
Big brains and strong bodies go to-
gether.
DR.. Ales Hrdlicka of the Smithsonian
Institution shattered the popular idea
Of the physically puny intellectual giant
by describing his measurements of ap-
proximately 100 members of the acad-
envy. one Of the most highly intellectual
groups in the world. They are. he said,
superiors in physique, health, strength
and longevity to the American popula-
ton at large. They have larger heads
than the average well educated and
professional Americans. There is some
evidence. DR.. Hrdlicka said. that hard
brain work increases the size of the
brain.
There is apparently conclusive
proof" DR.. Hrdlicka said. that the
strongest and ablest healthy minds go
generally with strong. healthy bodies.
Intensive mental work does not tend to
shorten the lives Of the workers"
Chemical Analysis Of Sun.
Although the sun is 100000 miles
away, 1t has been possible to subject 1t
to a chemical analysis.
Working with the spectroScope, So of
the 80 elements known on earth have
been identified there. according to DR..
Charles E. st. John of the Mount Will
son Observatory, Pasadena, Calf. OF
these % have not previously been rec
ognized. Among them are carbon and
oxygen in the atomic state.
1t is probable that there are other
elements in the sun which cannot be
detected by the spectroscope. DR.. st.
John said. The distinguishing spec
trum lines of such elements as flourine
chlorine, iodine, phosphorus neon, argon
and krypton are in the ultra violet and
cannot come through because of the
layer of ozone in the upper atmosphere
about so miles above the earth. Other
elements among the heavy metals and
rare earths have not been identified, he
said, because of the imperfect knowl-
edge of their spectra and the technical
difficulties in interpreting them.
The probability, he indicated, is that
the sun is made of about the same kinds
of matter as the earth. but in a very
different condition because OF the enor-
nous temperatures and pressures.
Cause of Magnetic Storms.
Magnetic storms on earth and the
aurora borealis of the northern heavens
probably are due to great blasts of ultra
violet light shot out from the sun and
striking the earth's atmosphere, ac-
cording to E. o. Hubert of the Naval !
Laboratory, who has checked
this theory by studying the behavior
Of comets.
Such ultraviolet light blasts, he said,
would cause comets to change shape, |
throw out new tails. or even to break
up. They have been observed to do all |
these things. A comparison of comet |
observations and magnetic storms dur
ing the past SO years shows that the
most striking changes in the forms OF
these celestial visitors have come al
most simultaneously with the magnetic |
The great comet of 1882, |
the largest ever observed, came at the |
same time as the greatest magnetic |
storm ever recorded. 1t split into four |
parts and was lost to view.
The unusual blasts of ultra violet |
light. it was explained, are shot forth |
at times of great disturbance on the
surface of the sun.
