MASTODONS DECLARED ALIVE
HERE WHEN COLUMBUS LANDED
Scientists Are Told of Music Taught by
Pictures, Magyar Mathematics and
Lost California Tribes.

/ Whole or in part, home lands OF II
tribes of Indians representing elgn
| linguistic stocks. 1t is doubtful II II
any other part of the world there are, II
so small an area, so many tribes speak
| ing different languages. Most OF these
tribes are fairly well known, but during
| the mining days several OF them were
| practically exterminated by the onruSr
| of gold seekers and the troops called IT
to help. So complete was the destruc-
| ton that in the case of four OF the
tribes the few survivors succeeded sc
] well in keeping hidden from inquisltive
| eres that not even the names OF the
tribes were ascertained by anthropolo-
gists."
Clock Loses Second in Century.
A new clock, keeping time by the
vibrations of a quartz crystal instead OF
a pendulum, was described by w. A
harrison of the Bell Telephone labora-
tories. Recording time to the thou
sandth of a second, this clock has many
advantages over the pendulum clock
although much remains to be done be-
fore it is perfected. In observatorles
where it Is necessary to preserve a per-
feet synchronization between the solar
and sidereal time, harrison said, this
clock can be operated so that the error
in the ratio of rates is less than one
second in a century. Eventually the
quartz crystal vibrations may prove
better measure of time than the move
ments Of the earth itself, SAID Prof.
Ernest w. Brown of Yale University.
There is increasing evidence that the
mysterious coSmic rays, bombardlng the
earth with such penetrating power that
they will go through 100 feet of water
are the result of the building up OF more
complex atoms of matter out OF the
simple hydrogen atoms, said Prof. r. A.
Milikan of the California Institute OF
Technology, the discoverer of these rays.
He explained, however, that the evidence
was not perfect and suggested further
could be eliminated. One is that they
come from the humiliation of matter
in outer space as it is transformed into
radiation and the other is that they
are the result of particles of matter
falling through electrical fields in the
outer atmosphere of the earth.
The possibility of two types Of hui
man beings-those who live long and
grow slowly and those who 60 through
er lives-was proposed by Prof. Frank
Boaz of Columbia University. This
theory was based on the actual growth
records of human beings. 1t is difficult
to interpret the statistics, he said. be-
cause of the effects of changing environ
ment and social conditions on the
amount and rate Of growth. Thus, 1t
seems, all the peoples of Europe now are
growing taller.
Magyar Civilization Praised.
All branches of science must con-
centrate on the remarkable lost CIV
iliZation of the MayaS, said DR.. A. ".
Kidder of the Carnegie Institution.
Archaeology, he pointed out, has reached
the point where it can go little further
without interpretative data from other
specialized branches of knowledge.
Recovery of this lost knowledge, he
said, will amply repay scientists. AS
an example, he pointed out that the
MayaS had made some advances in
mathematics, such as knowledge of the
arithmetical significance of zero, which
was not known to Europeans at the
time of the discovery.
Practically the same kind Of bac-
terium which is building up bog-iron
deposits today was at work in Virginia
in the Cambrian geological era. said
DR.. David White of the United States
Geological Survey. The Cambrian
represents almost the beginning of life
on earth and the tiny living organism
has continued with hardly any change
through the many million years which
have elapsed.
