planation of this is simply process
radiation of heat.
Anything that can run down."
DR.. Russell said, will run down,
and the contraction Of the stars is
simply running down process.
Through billions OF years they have
been hurting their energy out into
space, throwing it everywhere, gem
orally reaching nowhere. Little by
little they have been shrinking in
size and losing IN Feat until some
have condensed into the cooler red
stars"
Gases Virtually Solid.
Although science describes the
stars as gaseous" DR.. Russell
pointed out that the "gas" is really
many thousand times denser than
water. "It is perfectly possible" he
said, "to have a perfect gas that is a
thousand times as dense as water
and platinum" The sun is in such a
state, and millions of times hotter
side, from which we obtain our
necessary heat and light.
Change Is Slight.
1t is quite possible to determine to
a certain degree of assurance the con-
dition of the sun through a study of
the geology of the earth. Science can
trace, through the rocks and minerals,
something of the history of this planet
back for 1,000,0 100000 years. During
that time. at least, DR.. Russell said,
the sun was never much hotter and
never much cooler, although it got rid
of a lot of energy in that period.
The only reasonable explanation for
| this condition, he declared, is that the
! sun and the other stars have tre-
| mendous internal stores of energy. 1t
| is known that the internal heat of
some of them reaches 30,000,000 de-
grees Fahrenheit, and the small white
! companion of Sirius is believed to be
| even much hotter than this.
! Thus, although their surfaces ra-
diate heat and energy in bewilder-
! ing quantities. the storerooms inside
are constantly manufacturing and
| sending out more, and this process
| will keep up until they shrink to the
| point where their atomic bodies are
pressed tight together. Then the
| process of real cooling will begin
and possibly eventually leave the
stars cold planets.
To Live Billions of Years.
Although the sun drives out it's

| science, are believed to represent the

Arboretum Is Indorxed.

yesterdays discussions. Plans for a

near Washington were Endorsed.
