The McMath - Hulbert Observa-
ory, deeded Friday to the Univer-
ity by Francis and Robert R. MC-
tath and Judge Henry S. Hulbert,
enior judge of probate, all of De-
rojit, is an observatory excellent in
lesign and containing many me-
:hanical refinements, Dr. Heber D.
wirtis, director of the University
)bservatory, said yesterday.
"These men have designed and
built and excellent small observa-
.ory, which is equipped with a 101/%
nch reflecting telescope, the mir-
ors of which are made of pyrex,"
Jirector Curtis said. "The telepope

"The purpose for which the Mc-f
Vath-Hulbert Observatory was built
s as follows: to obtain through the
Wving picture camera records of
he motions of celestial bodies. We
Ill know that the features of the
noon shor different aspects as the
un rises or sets on the lunar fr-
nations, that Jupiter is 'revolving
rapidly on its axis, and that this
noon is circling about the planets,
but few students of astronomy can
ake the time or rpake the measures
eally to visualize this from actual
bservation. The McMath-Hulbert
project takes movng pictures which'
an be brought to the class-room
ad shown to a high school or col-
ege class, giving them in perhaps
hre to five minutes a better idea
>f suchmotions than they could
secure from telescopic observation
in many hours.
"A film giving the results of their
preliminary motion pictures of sun-
set and' sunrise 'phenomenon on the
lunar craters, the rotation of Jupi-
ter, and the motions of Jupiter's
sattelites, was shown last April at
the meeting of the American
Philosphical Society in Philadel-
phia, andi aroused great interest.
They are now securing pictures of
gxeater perfection."
The men are only waiting for a
good comet to come along to secure
a pictoral record of its rapid mo-
tion. ,Director Curtis is now design-
ing far the McMath-Hulbert tele-
scope an instrument for recording
the changes in the solar surface,
and the changes in the great clouds
of hydrogen or calcium gas called
prom inences which are seen at the
lirbof the sun. This is a much
o e difficult project,sandmthe
natine of the instruient is long
enough to inspire respect. It will
be called, a spectroheliokinemato-

"The mechanical genius of Rob-
ert R. McMath has produced a
number of 'mechanical refinements
to make the'arduous work of taking
such celestial movies easier," Dr. 1
Curtis sai "It must be remnem-
bered that a satisfactory 'run' of
film to show sun rise or sunset;
effects on the moon, the gradual t
lengthening of shadows till they
finally creep completely across a
lunar crater and leave the central
depression in darkness, is a matter
of six to eight hours' work, involv-
ing the taking of anywhere irom
00 to 2,000 separate pictures.
"Ingenious devices give the propcr
exposures on the film of the movie
camera, with the proper "dark" in-
tervals between. The telescope is
made to follow the moon quite
closely in two different directions I
by means of ingenious arrange-
ments of changing gears. Still clos-
er approximation to the actual and
irregular motion of the moon across
the sky are given by electrical fre-
quency changers, which change by
very small amounts the speeds of
the motors which drive the tele-
scope. All the devices are not only
novel, in the sense that they have
never before been applied to tele-
scopes, but useful in that they point
the way to the application of simi-
lar methods on larger instruments."

Observatory, with particular refer-
ence to these new and original me-1
chanical adjuncts, has just been,

Union Lobby Sees
Strange Gathering'
A student phenomonon unpre-
cedented in the history of the uni-
versity occurred Wednesday in the
lobby of the union. Probably the
largest single student "bull session"
of its kind to ever assemble spon-
taniously gathered for some strange
reason last night around a few stu-
dent orators and discussed life, lit-
erature and world politics from
seven o'clock until closing time at
At about seven o'clock an ami-
able discussion arose between Sher
M. Quirashi, '32, and Harry H. Kim-
ball, Grad, editor of the, Student
Socialist, on the subject of whether
violence or non-violence was the,
best policy for India. At eleven
o'clock Quirashi was more or less
.wilted in an arm chair and Kim-
ball, standing beside him, was hold-
ing forth to a young mass meeting
on the subject of the treatment of.
working men in factories.
Crowds ranging from a dozen to
over fifty filled the lobby 'in this'
strangely spontaneous student for-
um during the entire evening. Off-
cials at the de sk stated that this,
sort of gathering had never occur-;
ed before.\
