By FRED SCHOTT
EDITOR'S NOTE: This is the 24th
in a series of weekly articles on facul-
ty personalities.
Prof. Russell A. Dodge, of the
engineering college, characterizes
himself and his family as "solid
Michigan men."
Prof. Dodge said that his fam-
ily and forebears have been stu-
dents here as far back as the dais
of Dr. Tappan. One of his ances-
tors was a member of the first
graduating class of the University,
and Prof. Dodge is the first of a
family of six who graduated from
Michigan.
Graduate Assistant
After a short term as a gradu-
ate assistant in civil engineering,
Prof. Dodge began teaching full
time in the fall of 1921. He ac-
quired some of his early engineer-
ing experience with the city of
Ann Arbor, Bureau of Reclamation
and a local utility company.
Now professor of engineering
mechanics, Prof. Dodge specializ-
es in hydraulics, and confesses
that he is. "nuts" about it.
His other duties include the
teaching of general mechanics
courses -and membership in the
executive committee of the en-
gineering college.
As a member of the executive
committee, Prof. Dodge heads the
committee on research funds for
physical sciences and the com-
mittee for the acquisition of sur-
plus government pioperty.
Public Affairs Participation
Busy as he has been in the
classrooms, Prof. Dodge has found
time to participate in public af-
fairs. Ile is currently president
of the Board of Water Commis-
sioners and has been a member
of the Board for 15 years. In the
past he has been chairman of the
Community Fund, vice-president

Help Prevent
Tooth Decay
Electron Microscope
Applied to Dentistry
By ANNETTE RICH
Daily special Writer
The water you drink may be
one of the causes of the trouble
-or lack of trouble - with your
teeth.
According to Charles H. Ger-
ould, research engineer with the
Dow Chemical Cooperation, dif-
ferences in tooth structure re-
sulting from small traces of fluor-
ine in drinking water can inhibit
bacterial growth and cut down
dental caries.
Gerould worked on metals with
the newly-developed electron mi-
croscope when he became inter-
ested in its application to the
study of internal tooth structure.
B: gan as Hobby
Beginning the study as more or
less of a hobby, Gerould proved
that fluorosed teeth were com-
posed of a- much finer internal
structure on a submicroscopic
scale, than were normal teeth.
Gerould's work resulted in the
first successful application to
teeth of the electron microscope,
which details minute structure of
matter. Contrary to popular opin-
ion, fluorosed teeth are softer,
rougher and often whiter than
normal teeth, Gerould said.
He declared that life-time re-
sistence to tooth decay can be
built up by children if their drink-
ing water contains fluorine dur-
ing the period of tooth forma-
tion.
Cut Decay

One active member of the. Uni-
versity faculty Isn't set foot on
the campus for 21 yeas.
He is Professor Richard A.
Rossiter of the astronomy depart-
ment, who has been stationed at
the University's Lamont-Hussey
Ob s e r v a t o r y in Bloemfontein,
South Afrika since its construction
in 1926. He has never left the
countr since then.
Prof. Ro)iter s .o is to discover
new and unusual double stars-
All reports of his lates: discoveries
are made through the mail. Up to
the present time he has discovered
about 5300 double stars. Individu-
ally, these stars are of liile value
to research, but as a group they
mnake it possible to determine the
masses, or weight, of the stars.
No names are given to Prof.
Rossiter 's discoveries. They are

Professor, Absent 21 Years,
Is Still ember of U' Faculty

PROF. RUSSELL A. DODGE
of the Chamber of Commerce and
President of the YMCA.
He said he has been kept busy
enough so that he never developed
any hobbies-except travel, and
then he combined business with
pleasure. Although he has ex-
amined laboratories in several for-
eign countries, he said he is still
kidded about "never getting any
farther away from home (Whit-
more Lake) than Ann Arbor."
Knowledge of Machines
Asked whether his kinowledge of
mechanics had ever inspired any
inventions, Prof. Dodge admitted
that he once invented a very fan-
cy hinge and was happy until he

PAINTERS DANGLE FROM BRIDGE STRUCTURE--Two painters dangle by their safety belts
20i' feet over the roadway of the Triborough Brid;;e in New York City after their scaffold slipped
while they were at work painting the structure. The two men were rescued when fellow workers
swing them back and forth on the ropes until they were able to grab hold of the tower structure.
Uninjured, the pair climbed down the tower to the roadway.

ed. "It's poisonous."
The dental school, in conjunc-
. 2 tion with the United States De-
partment of Public Health, is con-
ducting tests with fluorinated

cities. The dental scientists are

the treated water at Midland and

rns and cay of, children in cities having
ordinary water.
Make Tests
Dr. Philip Jay, of the dental
school, reported that in the ex-
O 6 perimental areas, where from one-
half to one part per million of
fluorine has been added to the
Arcade water, saliva tests showed that the
< incidence of lactobacillus acido-
_='____philus is low. Dr. Jay believes
that the chemical structure of

hibit the growth of these bacter-
ia, which contribute to tooth de-
cay.

By TED MILLER
Have you ever wondered why
four wide staircases, lead from
the ground floor of University
Hall to the little traveled second
floor? There's a reason. .
Nearly three-quarters of a cen-
tury ago, some 1,000 students and
2,500 townspeople marched proud-
ly up those stairs, filed through
double wooden doors and seated
themselves on straight-backed
benches to help dedicate the new
University Hall and its grand aud-
itorium, considered to be the
"foremost need of the University."
Back in 1873
That was in 1873, when the Uni-
versity could boast only two edi-
fices, North and South College
Buildings, which now form the
wings of University Hall. With theC
influx of women students, the
University appealed to the state
legislature for more classrooms
and an "audience room to as-
semble her 1,000 children."
University Hall, sandwiched be-
tween the two original buildings,
was the answer. Immediately the
auditorium became the center of
University activity, with lectures,
musical programs, pep rallies and;
commencement exercises consti-
tuting a full schedule.
Enterprising" students did not
wait long to put the auditorium
to good use. They inaugerated
the Student Lecture Course, the
first of its kind in the country,
and brought international figures
to Ann Arbor.,
Arnold Was FlopJ
The British poet and critic
Matthew Arnold failed to impress'

his audience, reports indicate. Two
thousand assembled to hear Ar-
hold, but the Ann Arbor Argus
reported that he could not have
drawn 100 in a second appear-
ance because of his "lack of any
sort of gestures and perpetual
monotone.'"
Bryan's appearance in 1902
served to amplify a fear which had
been growing for a number of
years. The enthusiastic stamp-
ing of feet that greeted Bryan
caused the auditorium to shake
and prompted a faculty member
to warn the audience that this
practice was dangerous and add-
ed quite unnecessarily that the
building was beginning to show
its age.
Roof Leaked
Another source of distress a few
years earlier was corrected easily,
though with some misgivings. Di-
rectly above the auditorium rose
a huge 60-foot spire, which was
too heavy for safety and admitted
Ann Arbor's inclement weather
through its many leaks down upon
the audience below. For these
reasons, over the protests of sen-
timental alumni, the towering
spire was replaced by a smaller
one in 1896.
Things became more comfortable
all the way around when the Uni-
versity simultaneously substitued
the latest-type opera seats for the
punishing straight-backed bench-
es.
In 1915, Prof. Richard Hollister,
of the speech department, bought
his own curtains and rugs and be-
gan play production in the audi-
torium. Students showed im-

mense interest and Prof. Hollister
produced plays five times a semes-
ter for the next ten years. After
1925, the fire hazard became in-
creasingly apparent and the public
life of the auditorium came to an
end in 1930.
Now Abandoned
Behind its locked doors is found
only a shell of once glorious days.
The room is bare of seats and
some parts of the floor are torn
up.
For company, the old auditor-
ium now depends upon the regu-
lar visits of Prof. Avard Fair-
banks, instructor of sculpture, who
builds life-size monuments there.
Prof. Fairbanks is leaving this
summer to join the faculty of
Utah University, however, and
finally left alone, the aged audi-
torium will likely look forward
to its demise completely satisfied
with its long life of historic serv-
ice.

"If we find out four or five years
from now that the caries rate is
still high, we will know that this
fluorine water is the bunk. We
will have to go back to find out
what else water has," Dr. Jay said.
Naval Unit Asks
For Official Status
As a result of the successful vol-
untary naval reserve membership
drive, officials declared that they
will ask the Navy Department to
activate the unit on a regular or-
ganized basis.
If the request is granted, all
members of the reserve will re-
receive drill pay. Under the pres-
ent plan only those in the special
electronic section have been au-
thorized pay.
