prospects indicates, says the Mich-
igan Manufacturer and Financial
Record in its current issue, that a
gradual improvement is generally
expected for 1931.
Includes City Reports.
The survey report included the
following reports from various cit-
ies:
Muskegon - Manufacturers gen-
erally are optimistic. Muskegon
Piston Ring Co. reports unfilled or-
ders 20 per cent ahead of 1930.
Shaw Crane works expects s lo w
start and gradual improvement.
Fair to good prospects seen by oth-
er manufacturers.
Flint-Conditions have been help-
ed by rehiring of workers in plants
of Buick, Chevrolet, A. C. Spark
Plug and Fisher Body companies.
E. T. Strong, Buick president, sees
"more than a little evidence which
indicates a promising outlook."
Pontiac-Steaay return of busi-
ness activity predicted for year by
executives of Pontiac's leading fac-
tories. Motor firms see in new
models and more efficient sales or-
ganizations prospects for steadier
production schedules and more sta-
ble payrolls than in 1930 when the
average employment in the eight
principal plants was 13,263.
Local Survey Good.
Ann Arbor-Increased orders were
reported by most Ann Arbor firms,
and the American Broach & Ma-
chine Co. already is operating over-
time. Executives believe the year
will see a steady improvement in
conditions.
Port Huron-The past year was
one of expansion for Port Huron,
with three companies purchasing
f a c t o r y sites, paper production
above the 1929 figure and an in-
creased payroll by Detroit Edison
Co. Firms generally expect im-
provements during the next few
months.

Clements Libratian Gives Plans
for Washington Celebration
in Radio Address.
Speaking; of the Washington Bi-
centennial to be held in 1932 on
the two hundredth anniversary of
the birth of George Washington,
Randolph G.. Ada ms, librarian of
the William Ciements library, in a
radio address yesterday afternoon
from the University studio, stressed
the kind of activity contemplated
for this celebration.
"One example will suffice as to
the kind of activity planned," said
Adams, "and that is hilt thei na-
tional commission - a Washington
has decided that noth~iig could
more adequately mark such an an-
niversary than the publication of a
George Washington."
The project, he continued, is now
under way to print a 30-volume
edition of these letters, each book
of which will be at least 500 pages
in length.
Adams asked anyone who might
have valuable copies of letters writ-
ten by Washington, to send a copy
>f them into either himself or Mr.
John Fitzpatrc at the library of
Congress, who has been intrusted
with the editing of tis work.

bate topic for the second semester,
that of commercialism of student
athletics, came the report of the
National Student federation from
Atlanta, Ga., deploring subsidiza-
tion in college athletics. The opin-
ion was the result of a three-day
discussion and parliamentary fights
between student delegates from.
more than 175 college campuses in,
the United States.
The federation passed three reso-
lutions which summarized the gen-
eral student opinion on the prob-
lem. The first stated their general
belief, that the "sixth annual Con-
gress of the National Student fed-
eration of America deplores the
subsidizing of college athletics."
Their second and third resolu-
tions proposed that not only should
equal recognition be given to schol-
astic achievement as well as phys-
ical prowess, but that they would
sponsor a country-wide movement
to purge American colleges and
universities of commercialism in
athletics. The second resolution as
adopted stated "that the sixth
student federation go on record as
favoring the award of scholarships
on the same basis, regardless of

the possibility of bringing about a
nation-wide conference of college
presidents, athletic directors and
student leaders on commercialism
and professionalism in college ath-
letics."
