The completion of a two-year study

by the University Observatory is the I
latest addition to the field of stellaI

Michgan' Pl Ping offered this summer to boys and
Michigan's Play Production, stu- young men between the ages of 10
tory has specialized for 26 years. Prof.
Dean McLaughlin stated in an in-
terview recently.
The chemical composition of a star,
its temperature and rate of speed to
or from the earth can be determined'
by a study of- the photographs of the
star's spectrum, he stated. Various
dark lines differing in their intensity
and position in the spectrum are ob-
tained on the negative, from whichJ
one is able to determine the chemical
composition of the star's atmosphere,
he explained. "For instance the ele-
ment hydrogen will produce a dis-
tinctive pattern of lines which no oth-
er element can duplicate," Professor.
McLaughlin added,
Machines Measure Motion
The rate of speed a star is traveling
can be determined by the distance the
bands vary from the normal position
on the photographic plate and the
slight change in the wave length. Six
machines at the Observatory can
measure these displacement lines to
within one fifty-thousandth of an
inch and thus a stars motion may bej
measured to one half a mile per sec-
ond, he said.
"Stars hose spectra appear ab-
normal are those with which most
of the work in the observatory is con-
cerned," Professor McLaughlin stat-
ed. The spectra of one of these ab-
normal classes contains bright lines of
hydrogen instead of the usual dark
lines on the photographic plate. An-
other class, to which the Nova Her-
culis belongs, is composed of tem-
porary stars which without warning
suddenly appear brilliant in the heav-
ens and then slowly disappear, he
showed.
Stars Chaoge In Size"
By the 13,500 photographs the ob-
servatory has taken it is shown that
Gent dramatic group, was elected to
membership in the National Theatre
Conference recently, it was an-
nounced here yesterday.
The Conference includes 25 leading1
little theatre and university groups of
the country. Recently organized, it
elected 11 new members in its meet-
ing last week, approval being neces-
sary by 12 of the original 14 members.
The purpose of the Conference is
to aid little theatres in obtaining or-
ganization and better selection of
plays and materials for production.
And to enhance the opportunity for
better non-professional dramatic
work in the United States.
Play Production also has been hon-
ored this spring by "Theatre Artsf
Monthly," international magazine.
This month's issue includes a picture
of the Players in their performance
of "The Old Maid" which they gave
last year. The July issue will have an
article by Prof. Valentine B. Windt,
director of the group, on "Directing
Amateurs." It will also have a picture
of last year's offering of "The Pirates
of Penzance" and this year's Henry
VIII."

Students join the ship in the vi-
cinity of New York Harbor and may
remain on board from June 1 to Oct.
1 for any period of not less than three
weeks. The cadets will follow regular
daily ship routine receiving instruc-
tion in nautical subjects under the
supervision of the Captain Comman-
dant of the Academy. This is the
eighth year the course has been given
to acquaint boys with the possibilities
of a career as officer in the U.S. Mer-
chant Marine. Instruction, living
quarters and medical attention are
free. The only expense will be meals.
JANITORS TO MEET

Youth Congress
Meeting To Be
In Milwaukee~v
The Fourth American Youth Con-
gress will meet July 2-5 this year in
Milwaukee, Wis., it was announced
recently by that body.
This year's program will take the
form of a model Congress of the
United States. The group will in-
clude a Senate, a House of Represen-
tatives, joint committees and organi-
zational caucuses. Each local youth
organization is entitled to one rep-
resentative for each fifty members
and each national organization to
four members in the Senate.
Committees will be appointed by
the cabinet which will be nominated
ind elected at the first and second
meetings. Subjects to be covered by
;hese groups include: agriculture,
democratic liberties, education, labor,
peace, recreation and leisure time.

most disappeared while others have
grown stronger. A theory advanced
is that stars form new atmospheres
1which gradually or violently as the
case may be spread into space, Pro-
fessor McLaughlin said. That the
star's atmosphere expands and con-
tracts may be gathered from the
combined study of the star's rate of
motion and its change in the bright
lines, he showed.
In the case of Nova Herculis, its
light was+ at first very faint. Then
it apparently exploded and increased'
in brightness 100,000 times. A study,
of the spectrum showed that its line
pattern had divided into two parts.
The dark lines were displaced and had
short wavelengths showing that two
masses of gases were moving towards
the earth with a velocity of 200 miles
per second and 500 miles per second.
The bright lines remained with their

Will you know where your classmates are and what they are doing?
Will you be right up to date on what's happening on the Campus?
Will you know just what the new Graduate School looks like; how many thou-
sands are listening to the Baird Carillon ?
Will you be able to tell what the B.M.O.C.'s and the'B.W.O.C.'s are doing to the
University you left behind?
