his particular mode of balancing, while
the Schriver machine is varied enough
in construction to conform to his man
ner of maintaining his equilibrium in
the air. Schriver. however, considers
that his machine has one improvement
over the Curtiss make. The machine at
Moanalua Field has Just one plane for
ward to steer the fiier up and down.
where the Curtiss biplane has two paral-
lei planes attached to the forward
frame.
Art of Steering.
Schriver explained Yesterday that the
TWO planes sort of boxed the wind
which hit the main wings after passing
through these forward planes, which
made the airship ride unsteady. The
one plane in front he continued, re-
duces this motion to great extent. al
though the wind hits this plane first
and makes the machine rock like sail
ing over the waves. They are expert
menting now with machines, Schriver
said, to throw all the control to the
rear and do away with these forward
planes altogether, and when this is ac-
complished the machines will be much
more steady on the wind
Another innovation on the Schriver
biplane is in the position of the alerons,
or wing tips as they were called until
some Frenchman tackled on this fancy
name. On the Curtiss machine these
narrow planes extend out from either
side, attached to the ends of the wings
and are alternately lifted or lowered
aft to balance the machine.
In the Schriver machine these bal
ancing planes are made a part of the
far sections of each upper and lower
wing, so that when worked from the
seat in the center section of each
( wing is raised or lowered to tilt the
machine as desired.
Mechanical Balancers.
These aierons are worked by wires at
tached to the back of the aviator seat.

J char, having high arms on either side
These come well up under the aviator s
arms, and he tits them to right or left
1 by throwing his body either way. When
he throws his body one way, it raises
one aleron and lowers the other. which

turn or rights it when it 0verbalances

! Schriver's machine, which will he
used by Mars here, is also broader than

wings, Is thirty-two feet. while the
! wings on the Curtiss machine measure
only twentysix feet. Schriver's wines
also have a depth of five feet, while
the Curtlss wings are only four and a
half
The aviators have paraphernalia
enough here, said Capt Thomas Bald

different motor will be installed in
the Schrlver biplaue than is usually car

Special Motors.
This motor is exactly like those used
IN an automobile, only reduced to the
least possible weight 1t has eight
cylinders, generates fifty horsepower
and only weighs two hundred and thir-
ty pounds. This motor will be installed
right In the center of the biplane di-
rectly back of the aviator 5 seat with
the steering wheel in front, so that he
may alter his course and balance the
blpiane at the same time by shifting
the arms of his high chair to the right
or left by throwing his weight either
way.
1t all looks very simple and Sehriyer
says it is on calm day Asked if fly
ing was good sport this bird man and
master mechanician pronounced it
delightful pastime under ordinary con
ditions When the wind is blowing
hard, however, Schriver explained. it
keeps the aviator too busy irving TO
anticipate what is coming next and the
strain of keeping on the alert for vary
ing air currents makes i too strenuous
for pleasure. There is nothing very
dangerous about flying around FIVE ort

Honolulu folks would own flying ma

and would take pleasure trips around
to the other islands.
In response to a query as to the cost
of fving machines Schriyer said that
the engine alone Of his machine cost
three thousand dollars. but he thought
that in time they ought to come down
to five hundred so that biplanes could
be turned ont fer the market for about
fifteen hundred dollars apiece. At the
present time however, all the money
that comes in from exhibition flights
