CHAMBERLAIN SAYS
) INTERIOR OF THE
EARTH is SOLID

Chicago, Nov. 16.-New doctrines
OF geology, based on a new theory of
the origin Of the earth. were outlined
to the National Academy of Sciences
here by Prof. Thomas C. Chamberlin.
emeritus head of the department Of
geology of the University Of Chicago.
Emphasizing the revolutional mo-
tons OF the earth as a planet, which
nave largely gone unnoticed in
geology. Professor Chamberlin declar-
ed that they were some thousands OF
times greater than the more tangible
Migratory energies" such as light, heat
INC sound.
Says Earth is Solid.
Discarding the old view of the ne
buiar hypothesis that the interior OF
the earth is molten. Professor Cham
berlin told the academy that it was
solid.
Professor Chamberlin, who is one
of the worlds foremost biologists,
presented W papcrs:~ THE Con-
trasted Types Nof Earth Energy and
Their Relation Values" and This
Paths Taken by Energy in the Self
Compression of the Earth" Profess
sor Chamberlin called attention to the
fact that the older studies of the
earth related chiefly to its substance
ana that recently attention has turn
ed more largely to its energies.
lie pointed out tina formerly it was
supposed that the earth was once in a
gaseous state and that 1t condensed
from this into a molten globe. Its sur
face conhguration and it's deforma-
tons were assigned to cooling, The
studies of the earth's energy and mo-
nientum. however, revealed serious
dlfhculties in making such q history
fit the facts disclosed by later inves-
tgatlon. DR.. Chamberlfn abandoned
the old view some twenty years &
and offered a new view known az the
planetesimal hypothesis. Under this
view the earth was built up very
slowly by gathering in minute bodies
whose energies n momenta were of
the same sort as that Of the planets
INTO which they are gathered and
hence they met the old difficulties.
Makes Changes Necessary.
The new view. however. makes 1t
necessary to recast many of the old
doctrines of geology to. bring them in
to accord with the new basis. DR..
Chamberlin has been at work upon
this for several years.
His first paper today brought out
the remarkable preponderance OF
the constructive revolutional energies
over the ~asitative Migratory energies"
This appears to have escaped at
tention.' Professor Chamberlin said,
because the former are so singularly
un~obstrusive. The latter, though
much inferior in real value. are very
demonstrative n ave had the lions
share of attention.
The revolutional motions OF the
earth as a planet and the similar mo-
tons now believed to be essential fea-
lures of the atoms, largely escape or
binary notice, while the vibratory ac-
tons. such as sound. heat. light, the
A-rays, etc, make themselves felt
very keenly. especially If these r a,
all intense.
I'VE are 80 constituted that we are
sensitive to these agitative energies
but not to the other type. Our sense
impressions need therefore to be
rectifed."
BY estimates Of the real values Of
the two types, DR.. Chamberlin show.
ed that the obstructive revolutiona
energies connected with the earth are
some thousands of times greater thar
the more tangible Migratory energies
The two kinds. however, cosoperat'
with one another n r mutual,
INTERCHANGEABLE. ~
DR.. Chamberlin's second paper re
lated to the self-compression OF tn
earth. Under the new view, this i
merely the pulling together of a soil,
body by its W attraction. The eartl
\ work goes on, he said. Much Of tn
energy goes to make up more com
pact n more resistant structures.
Some, however. goes to liquify tn
more Equitable substances. but thes
are squeezed out about as fast as the,
reach sQueeZable volumes. They thu
leave the interior solid.
