Lake Vessels Found To Be
Stronger Than Ships of
Similar Type on Oceans

A message from President Harding
on the American merchant marine,
which is expected to sound the kay
note Of the Administration on the
special session of Congress this month,
is to be delivered at the marine ex-
position at the Grand Central Palace
tonight by Secretary of the Navy
DENLY. While the President is pre-
vented from being present in person
because of the illness of Mrs Harding.
1t is understood that his speech by
proxy will have unusual significance.
The construction of vessels used on
the Great Lakes is stronger, for the
service they have to perform, than
similar ships on the ocean, according
to special studies made by two mem
bers of the Society of Naval Architects
and Marine Engineers, Herbert G.. Sad
Ter and A. LindbIad. In paper read
Yesterday before the general meeting
of the society, in connection with the
Marine Show at the Grand Central Pal
ace, it was said that the theory that
these ships are weaker than their deep
sea counterparts is definitely dispelled
Wave Lengths Studied
In reaching this conclusion, the two
investigators made study of wave
lengths and stresses on the Great
Lakes. 1t was found that as rule
waves of more than 25o feet in length
are rarely encountered and that the
longest on record is $50 to 400 feet,
The height is twenty feet at the
maximum.
Another paper of unusual interest
Yesterday was that of Elmer A. Sperry,
WHO outlined the scientific facts be-
hind Iron Mike" the automatic steer
ing device, which performs the task
more efficiently than the most compe-
tent human quartermaster. Illustrations
we're submitted to show the better
results obtained with the use Of the
gyro compass than the magnetic com
pass. Among the most important
achievements are reduction in the
helm resistance. which retsrds the
ship, and the zigzagging, which makes
it necessary for the ship to cover
longer distance between ports.
Commander Herbert S. Howard
made an address on naval design as
result of the Battle of Jutland. Z.
A. Stevens talked on the application
Of Dyson's method to propellers of
ocean-golng merchant vessels. Profes-
sor E. M. Bragg gave study of the
wake Of models by means of current
meter. Rear Admiral D. w. Taylor
outlined some experiments on propel-
ler position and propulsive efficiency.
The annual banquet of the society
will be held tonight at the Waldorf
Astoria.
Boy Scouts on View
The Boy Scouts on Thursday, Friday
and Saturday evenings of this week
will give a demonstration of their
work with a specially trained troop of
Scouts from Brooklyn. The demonstra-
tion will be held every evening at 1880
o'clock on the mezzanine floor at the
Marine Show, Grand Central Palace.
The boys will show how towers are
built together with pioneering and
bridge and raft building. They will
also give demonstration of first aid
work, showing artificial respiration
and the so-called freman's lift, used
in carrying away unconscious persons.
They will give performance in sig
mailing by both the two-arm and the
one-iag international methods. Fancy
knot tying aud fire starting by rub
hing dry sticks together will be part
of the performance.
