Novel Course For the Youngsters Of
New York Public School-Swap
Ideas and Sell Parts of Machines.
Hope to Pass the Rubber Band
Motor Stage.
New York city has juvenile school
of aviation in Eighty sixth street
which has for its pupils boys Of pub
lie school q. These boys are not a
little proud Of the fact that they are
pioneers in this science, for their
school was the first to introduce the
work in the physics course. These
boys have become tutors to others
less advanced in the subject and are
making copies Of their best models to
be used in other schools for instruct
ing classes. The boys took orders re-
Gently for two New York schools. one
from school in Raleigh, N. c.. and
two from the high school in Adrian.
MINI. Interest is growing so rapidly
that there is to be national organ
ization with interstate meets.
Any boy who can furnish material
for one model can become member.
The cost of model is about 60 cents.
The boys often reduce this expense by
trading parts. For instance. one boy
gave another piece Of aluminium for
a propeller for piece Of spruce with
which to build frame. Some OF the
boys show keen business instinct in
guarding knowledge Of the places
where they can secure the best rub
Der bands. They also bargain their
trade secrets.
A Valuable Invention.
A patent office has been established
where boy can protect his ideas.
The first boy to file an application
was Victor Ely, chap about eleven
years old. He has invented a pro-
peller, made Of laminated spruce,
which is said to give large amount Of
efficiency. This is considered val
liable invention. as it requires more
skill on the part of boy to make a
propeller than any other part.
Oscar Schlegel has taken out patents
on an attachment Of the motive power.
Frank Hader has patent for the ar
rangement Of planes along the center
rod, and ]. Brown has a device for
maintaining equilibrium. A catapult
for launching aeros belongs to How
ard Mallon. Several weeks ago the
boys conceived the idea Of forming a
stock company and capitalized it at
$50. Shares of stock were issued with
par value Of 10 cents, and they have
now advanced to II cents.
Far In Advance Of British Youths.
The boys Of school II are making
an effort to bring about an utilization
with the Juvenile Aerial League of
Great Britain. organized under the
of London. A. e. Horn, the Instructor
Of the class, says that the boys Of the
United States are far in advance OF
English boys.
The boys began the work Of flying
kites, and this gave them excellent
ideas Of the atmospheric conditions.
They also visit the weather bureau at
the Central park arsenal. Almost any
one Of them can roughly predict the
weather conditions, and they are now
making weather flags to fly from kites.

with the boys, it isn't the best fier.
! for its double structure is too heavy
to be propelled by the rubber band
motive power. Most of the prizes have
been captured with the monoplane
type. More than 100 boys have built
successful models on the single plane
line.
Miss Hintze, the German teacher,
has offered a cup for a model aero
plane to rise from the ground by its
own power and fly 100 feet, to be COM
peted for at the next contest. The
boys hope in short time to make
models that will fly 1000 feet. So far
only rubber bands have been used to
supply the motive power. but the boys
| are constructing an engine with alu-
minimum geared wheels connected with
clock spring to attain 40 revolutions
a minute. They calculate that with
this power an aeroplane can be sent
from 1000 to 1000 feet.
