Lamiont-Hussey Observatory-
Fruition Of Generosity, Vision

In His Memory
in the hope that the southern-most
zone of the double star survey would
be completed under more favorabler
conditions at a southern station. It
was but a few short years before plans
for this southern station began to
take concrete form.
In June, 1908, Mr. Lamont author-
ized Professor Hussey to proceed to-
ward the construction of a telescope
of 24 inches aperture for the study of'
the double stars of the southern por-
tion of the sky. He made an initial
contribution of 1,000 dollars.
During April, 1909, Professor Hus-
sey studied the 26-inch refractor at
the Naval Observatory, in order to se-
cure data for the designs of the Ann
Arbor telescope. Plans and drawings
for the new telescope mounting were
begun in 1910.
A contract for a 24-inch lens was
placed with Alvin Clark and Sons
in 1911. A pair of discs for a 24-inch
lens were ordered from a French and -?
a German company in 1913, but these
were never delivered. It is said that
during the World War, the govern-
ment of both countries seized the
discs and cut them up to be used for PROF. WILLIAM J. HUSSEY

Reports Survey

Reaction Times
Automobile Drivers Show
No Efficiency Advances
After 4 Years Experience
Do not believe the man who say
he is able to "stop his car on a
dime." At 20 m.p.h. the best he is
able to do on a dry pavement is to
halt his car after going a distance of
:7 feet from the time he had his first
yarning to stop.
This is merely one of a set of in-
teresting facts uncovered by Frank
0. Olmstead, assistant research en-
gineer of the Michigan State High-
way Department in a survey conduct-
ed by the department in the interest
of public safety.
The survey, which includes results
from the reaction tests given at the
Engineering Open House last spring
also showed that after four years
experience the individual ceases to
improve as a driver and that the
drivers between the ages of 17 and
31 are the most alert.
The results of the survey, which
have not been officially published as
yet, are of particular interest at this
time because of the fact that the
machine to test the driver's reaction
to a stop light is at the Union where
it will remain for the remainder of
the week.
The importance of split-second
driving reactions is readily seen when
one realzies that at 40 m.p.h. an au-
tomobile travels at the rate of 57 feet
per second. Mr. Olmstead found that
the faster drivers have more acci-
dents but since they drive more miles
than the slower-moving motorist the
chances of accident are equal to all
motorists.
Mr. Olmstead drew the conclusion
from his survey that the best means
of influencing drivers to drive safely
is an educational program pointing
out to them the need for alertness
at all times.
Poets Best At 25,
Psychologist Finds
An Ohio University psychologist
has reported, after research, that
writers reach their peak in literary
production at forty-one, chemists are
best between thirty and thirty-five,
inventors at thirty-five, and astron-
omers between forty and forty-five.
According to Dr. Harvey C. Leh-
man, poets produced their best work
between twenty-five and twenty-eight
and short-story writers before thirty-
five.
Doctor Lehman asked English pro-
fessors of various universities and
colleges to select what they regard-
ed as the 2,000 best works in litera-
ture. Taking their selections, he
drew a graph showing the average
number of miscellaneous publications
per chronological age level per living
writer. The graph showed writers'
productivity ascending more rapidly
before forty-one than descending af-
ter. There was, however, a sharp
descent after forty-four, Doctor Leh-
man said.

Consider Role
Of Vandenberg
Half Of June Convention
Delegates Are Chosen;
Steiwer Also Backed
WASHINGTON, April 25. - OP) -
The names of Senators Vandenberg
of Michigan and Steiwer of Oregon
assumed increased importance in Re-
publican councils this week as the
personnel for the June convention
became almost half complete.
If a deadlock threatens between
the now leading possibilities for the
presidential nomination, friends of
the two legislators would be in a
more starategic position to advocate
them at Cleveland.
No suen aeadlock has been predict-
ed. But observations heard at the
capitol following endorsement of Van-
denberg by the Michigan Republican
been named convention keynoter, in-
dicated party leaders had not dis-
missed the possibility. A way to har-
mony is the principal goal of some.
Action today in Colorado brought
the delegates so far named to 477
of the 1,001 total. Of these an un-
usually high percentage are nomi-
nally uninstructed, 376 in all.
Claims by some followers of Gov-
ernor Landon of Kansas, Col. Frank
Knox of Illinois and Senator Borah
of Idaho overlap to an extent that
suggests the full story must await
the actual balloting.
WThether any of these three are
found within striking distance of a
nominating majority, or 501, at the
outset may determine the course of
advocates of Vandenberg, Steiwer,
Senator Dickinson of Iowa or others
at present talked of as "dark horses."
Borah said he would decide whether
to go to Cleveland as a delegate, which
would be necessary for service on the
committee, by the time the Idaho
delegation is picked May 9.

BOSTON, April 26. - ()P) - A little
of the heat which destroys burned
papers resurrects them photograph-
ically, makes black pages seemingly
white, and print and writing distinct,
in a new development of -infra-red
photography here.
The heat photography recreates the
original page of any paper not
crumbled to dust. The technique
was worked out by Gustavus J. Es-
selin, chemical consultant.
Pages so coal black that neither
eye nor microscope distinguishes
traces of their original printing or,
writing come out white to gray in
the infra-red photographs. The
words written on them retain their
original blackness, form and clarity.
Heat 'Rumples' Paper
The pages might appear all white
except for the fact that heat always
rumples them. The white color is re-
stored only at the level of perfect
focus of the camera. Areas slightly
out of focus appear gray or dirty.
The infra-red, or heat rays, photo-
graph what is left of the original
structure of the paper and the print
in the ash remaining after the fire
destruction. The heat reflects the

This new use of invisible light dif-
fers from the work done with ultra-
violet, which brings out things often
invisible to the eye, like erased writ-
ing and chemical spots. The ultra-
violet rays cause the invisible sub-
stances to fluoresce, that is, to give
off light of their own.
The Infra-red rays produce no
secondary glow, but take the place of
visible light in restoring to sight
>omething gone beyond the reach of
visible reflection. Together the two
processes promise to narrow still
further the crook's chances of com-
pletely destroying evidence.
In fires valuable papers, enclosed
in filming cases where they do not
blaze, are often destroyed by heat
that blackens them completely with-
out crumbling. Such papers turn
white again on the.infra-red plates.
The burned inks still appear black
because they absorb infra-red to
blackness the same as they absorb
light.
Alterations undetected before the
documents were burned sometimes
show up under the heat photograph3
