CHAPTER VII.
MR.. wADDY INVESTS.

eyinced Intelligent comprehen-
sion of the heart of Carson's explana-
ton. Carson explained that his aero
nef differed from all others in having
wings like birds, which did not fap,
like those of the absurd orthopters and
vet used half their surface in beating
the air with straight thrust like that
OF an oar in water

mot at ALL" answered Carson. '"The
screw can never be effective. because
it strikes with slant. It will do in
water, but air requires a more effec-
tive thrust. When your propeller
blade moves at hundred miles an
hour, say. you have lift Of thirty
pounds to the square foot of surface
with the direct stroke. But the surface

"Now, how dye fgger that?"
Carson repeated laboriously.
Why" said Carson, Il can lift
weights that none of the other airships
can stir and fly off like an eagle with

The farmer-banker and the inventor
were so absorbed that they scarcely
noticed the entrance Of q messenger
from the institute with a message
from MIR. O'Grady asking if Mr.. Craig
head would step outside for q moment
nor Craighead's withdrawal and re-
turn.
The direction of the blow Of the
propeller" said Carson, Ais under per-
feet control. A birds wing isn't. This
is a better wing than an eagles
kin you raise right straight up,"
asked Waddy, without running along
like buzzard?''
Il sure ean," replied Carson, falling
into dialect "No bird can do that-no
big bird. It's better, stronger flier
than any bird. The best any other ma
chine can do is to support four pounds
to the square foot Of surface. With
my new motors / can fly off with five
times that, and I've got four times
their bearing surface. I can carry
mail and express at a profit or passen-
gers that can afford it. can hover
over ship with good heavy torpedoes
and sink her and overtake any vessel
that floats. CAM
What kind of motors you got?'' In
terrupted Waddy.
Carson went into details. The old
man looked through his eyebrows,
whiskers and mustaches at Carson and
the dra awnings. :
What if your engines STOP" he
asked, when you're a mile high and
over water mebbe?'
II can soar" answered Carson. II
can make headway and gain height
with no power if there's a wind, and
I can stay up for hours with the pro-
pellers set for aeroplanes. But the
best thing haven't mentioned-the
gyroscopic balancing Device"
whats that?" asked Mr.. Waddy.
"Why, it's the successful application
of the gyroscope to aviation"
'"They used to talk about that" OBJ
served Mr.. Waddy, "long ago-the
Brennan single rail roads. I thought
it turned out that the horoscopes was
too heavy fr air work."
'"They are too heavy" cried Theo-
dore. ''if you use them to do the bal
ancing. That's sure. And so we have
had to balance by feeling, just as we
do bicycle. Thought isn't quick
enough, so you have to rely on feeling,
as bird does. But I use little gyro-
scopes not to control by their weight
and stress, but to distribute power to
the wings and rudders-positive, auto
matte distribution Of power. Why, if
the engineer Of my machine should
fall dead it would fly on just as he set
it until the fuel was exhausted. 1t
feels and thinks"
They did not notice the opening of
the door nor see the woman who en-
tered ar.r-....-
"Papa," she said.
Mr.. Waddy rose hastily and faced
her. She looked like Mr.. Waddy, but
was undeniably pretty. He was blocky
and short; she, round and plump, with
small hands and feet The turned up
pug nose of Mr.. Waddy was modified to
a delightful little retrousse effect in her.
Papa said she, "this is hardly
place in which to entertain these gen.
tlemen. We have cleared out the east
parlor."
"Oh, yes!' assented Mr.. Waddy, with
feverish haste "To be sure, Caroline!
Take 'em in, won't you? I've got to
see the hired man. My daughter, Mrs.
Graybill, Mr. Craighead; Caroline, "a
a friend of mine, Mr.. Carson Of Ala
bama. Excuse me for minute, gentle
men,
Supper" said she, smiling, "will be
served very soon."
The long dining room was gloomy
with decayed gentility-black beams,
dark wainscoting and broad plate
rail bearing wrenches, -clevises, oil
cans and baskets Of eggs labeled as to
breeds and dates. During the meal
Craighead came out amazingly in his
