Carnegie Institution Arranges
Talks by Leaders in
Research.

A preliminary schedule of lectures,
touching a number of scientific prob
lens from archaeology to physics.
which will be open to the public
without charge. was announced to-
day by the Carnegie Institution OF
Washington, to be delivered this
Winter at it's administration build
ing, Sixteenth and Z streets north
west
Among the lecturers thus far
listed are some of the worlds fore
most students of science, including
members of the institutions own
staff. They will discuss some Of the
problems of research that the insti-
tuition has been investigating during
the past year. representing an in
tensely interesting field of scientific
endeavor.
DIR. Morley TO Speak.
Few branches OF science hold more
interest for the lay reader today than
archaeology. and the first Of the
coming lectures will be repetition
Of DR.. Sylvanus G. Morley's address
| on discoveries at the initial exca-
vations at Chichen liza, long buried
capital OF the lost Maya race, IN
Yucatan
DR.. Morley delivered this lecture
twice In October. One was at a public
meeting In the administration building
and the other at special meeting
for the Archaeological Society OF
Washington. So great was the in
terest Of the public at the former
| lecture that the auditorium was filled
to overlooking and il was necessary
| to turn away more people than were
admitted.
Out OF Difference to public demand
for a repetition of the lecture, the
institution announced that it would
give the people another opportunity
later to hear the lecture, which Is
illustrated with excellent lantern
slides. The date has now been def
nitely set as next Wednesday eve
ming, December 3. This lecture is for
the benefit OF the public and no seats
whatever will be reserved.
No cards of admission will be nee
essary. The doors Of the auditorium
will be opened promptly at O'Clock
and the lecture will begin at $3.50
O'Clock.
Astronomer 10 Speak.
At $40 o'clock the following Fri
day evening, December 5, DR.. A. E.
Douglass, director of Steward OBJ
servatory and professor of astronomy
al the University OF Arizona, will de-
liver an illustrated lecture on cycles
in the development of tree rings as
an evidence of climatic variation.
Dr.. Douglass will describe how. In
the dry degions of the Southwest, the
rings of the yellow pine give an ap-
! proximate record OF rainfall. Such
records collected from many differ
ent localities give data for estimating
some characteristics OF the droughts
in the last 500 years. The trees thus
serve as recording instruments and
enable science to judge of climate
variations, some Of which repeat
themselves in the form of cycles.
Three additional lectures have been
arranged for the first two weeks o.
January, the definite dates to be an
nounced later. One Of the most in
teresting OF these will be a descrip-
ton by DIR. John A. Anderson, physi-
cist of the Mount Wilson Observatory
of the Carnegie. Institution of WASH
ington, concerning his high temper
ature work with the electric spark.
The other two lectures during those
weeks will be by Dr. V. Bjerknes OF
the Geofysisk Institute, Bergen, Nor
way, on his studies in recent years OF
dynamic meteorolosy and hydrography,
with special application to long
range weather foTecasting.
Early III February it is expected
that DR.. A l.. Day, director OF the
Geophysical Laboratory OF the in
stitution, will deliver an Illustrated
lecture relative to recent volcanic
activities in Hawaii
