Trade Meeting
Will Consider
State Barriers
Sessions Of Conference
Will Include Speeches
By Truitt And Ruthven ,
Consideration of the pros and cons
of trade barriers will feature the in-"
itial session of tne two-day Confer-
ence of Trade and Industrial Secre-
taries which will open under the
joint sponsorship of the Ann Arbor
Chamber of Commerce, the Exten-
sion Service and the School of Busi-
ness Administration Friday, April 19,
in the Union.
Paul T. Truitt, chairman of the
Interdepartment Committee on In-
terstate Trade Barriers, will discuss
the question from the interstate point
of view. His talk will be followed by
considerations of "Michigan's Stake
in Interstate Commerce" and "LegalI
Aspects of Interstate Barriers" by
Profs. Edgar H. Gault and E. S. Wol-
aver, respectively, both of the School
of Business Administration.
President Ruthven will address the
delegates at a luncheon meeting to
be held in the Union. He will be"
introduced by Ira M. Smith, registrar
of the University and president of'
the Chamber of Commerce, while
Arthur E. Raab, chairman of the
State Labor Mediation Board, will'
interpret the functions and compo-
sition, of the Board at the second ses-
sion of the Conference.
"Federal Labor Legislation" will be
the topic of the second day of the
Conference. C. W. Otto, secretary-
manager of the Lansing Chamber of
Commerce, will preside, and Albert
E. Meder, attorney for the MVichigan
Manufacturers Associations, w il l
speak on the Wagner Act at 10 p.m.

Citizenry Aids
Maladjustment
Sociologically
Becaufe of the interest of Pres-
ident Ruthvent and local citizens in
he problem of helping children to1
eec:me better adjusted, the Ann Ar-
.r Children's Service has been able
o aid the normal development of'
many maladjusted personality cases.
In 1931, President Ruthven helped
'o form a treatment and planning
conmnittee in conjunction with the
scciclcgy and psychology depart-
mcnt= end the School of Education
to guide boys with behavior diffi-
culties. The committee, under the
direction of George Alder, was given
a grant in 1935 from the Rackham
Fund for a Social Research Project,
originally summer camp work, and
later a year-round follow-up of the
select group of boys. The project,
which was in existence three years,
was supported during the last two
by an Ann Arbor family, which pre-
ferred to remain anonymous.
The project came to a close in
1938 and was such a success that
a group of persons in the community
met to discuss a future for this type
of service for Ann Arbor. The pres-
ent Children's Service Bureau was
the result. Under the direction of
Gilbert Anderson, the Bureau, lo-
cated at Perry School, has been en-
larged to include girls and is now
entirely a service group, without any
research involved.
Graduate Education Club
To Hear Sellars, Curtis
Prof. W. R. Sellars of the philosoply
department will speak on "The Philo-
sophy of John Dewey" at the meeting
of the Graduate Education Club at
4 p.m. today in the graduate library
of the University Elementary School.

The course was originally designed
to enable commercial pilots to learn
"blind-flying" and thus enhance their
chances of securing better jobs. Bel-
lak's reason for taking the course,
however, is that he has learned to
take such long flights in his sailplane
that at times he must meet blind-
flying conditions.
The story behind Bellak's decision
to enroll in the course is told by
Dwight Reynolds, instructor in the
Civil Aeronautics Authority Flight
training program here. The glider
ace was in Ann Arbor when the Link
Trainer, the non-flying. ship which
simulates all the conditions of actual
flight, was being installed. He decid-
ed to try the Link out.
So little, did he know of instrument
navigation, however, that he had to
give up in his attempts to control
the Link after three minutes. He be-
gan to wonder then, Reynolds said,
what would happen to him if he ran
into heavy fog while on one of his
long glider jaunts.
Dr. Purdoin Will Attend
Convention In Chicago
Dr. T. Luther Purdom, director of
he Bureau of Appointments and
Xccupaticnal Information will attend
he North Central Association con-
ention tomorrow in Chicago.
The Association is an organization
,f secondary schools of certain scho-
lastic and progressive standards.

fessor Van den Broek challenges, leads
to several inconsistencies and con-
tradictions'in actual practice.
A perfectly elastic substance, he
contends, is ruled out as totally unfit
for structural engineering purposes,
yet in dealing with actual construc-
tion materials, stress calculations are
based on the idealized view that the
materials used can be considered as
being within the bounds of perfect
elasticity.
High grade glass, Professor Van den
Broek points out, manifests two pro-
perties, namely, great strength and
perfect elasticity, yet in common prac-
tice, no engineer would conceive of
building a large structure from this
material. So long as stress and load
are within the elastic limits, present
theories raise no objection to the use
of glass as a building material, yet
engineers know that such a practice
would be a physical impossibility.
To clear this contradiction between
"theory" and practice, Professor Van
den Broek proposes the consideration
of a property called 'ductility' in
computing load limits and safe capa-
cities. Ductility, in short, takes into
consideratica the behavior of struc-
tural merabers after the elastic limit
has been surpassed.
It admits that constructural mater-
ials may, and invariably do, at least
in localized sections undergo deform-
ations beyond the range of elasticity.
By admitting such deformations, the
theory of limit design can then anal-
yze their nature in order to extend

and establish a maximum deforma-
tion and maximum load consistent
with safety principles.
That the theory of limit design has
practical applications has been shown
by the experience of C. M. Goodrich,
chief engineer of the Canadian Bridge
Company. Some 200 full sized high-
tension electrical transmission towers
have been constructed by that com-
pany, all designed according to the
principles of the theory of limit de-
sign. That none of the towers, when
tested, failed to carry their full de-
sign limit and overload. Professor
Van den Broek contends, places a
strong empirical approval on the
theory of limit design.
The underlying principles of the
theory have also been generally ac-
cepted by severalschools of European
engineers. Notable among these are
the Dutch.
Students To Read
Papers At Meeting
Reading of papers, prepared by stu-
dent members for a national elimina-
tion contest, will feature the meet-

meeting, of which one will be select-
ed for competition at the final elim-
ination contest Monday, April 15 in

last year was Jack Chapman, '40E,
who placed third among contestants
from all parts of the country.

clude Owen Broders, '40E, "Automatic
Drilling Units;" Louis Vander Eyk,
'40E, "Chimney Design;" Cornelius
Boogaard, '40E, "Balancing of Turbo-
Generators," and William Armor,
'40E, "Carburation."

Russia has decided to create a 12th republic within the Soviet
Union, incorporating territory won from Finland (shaded areas) with
Soviet Karelia to form the Union Karelo-Finnish Soviet Socialist Re-
public. All'of the 13,990 square miles ceded by Finland, except a small
section near Leningrad, will be included in the Republic whose borders
are indicated by a dotted line. It has been disclosed that Russia has
built a railway (arrow 1) linking the Sortavala-Viborg line with the
railroad between Petrozavodsk, Karelian capital, and Murmansk. An-
other line is under construction further north (arrow 2) to link Soviet
Karelia with the Kuolo-Jarvi region.
All of the territory shown above as ceded by Finland to the Russian
government was bitterly contested during the three-months conflict
recently ended by the signing of a treaty in Moscow. This map was
prepared by the Associated Press.
