a YING MACHIRE.

The experiments made in the Haute-
Garonne, in various parks near Paris, and in
the workshop of the savant, prove that his
machine flies 1t resembles a great bat, Of
which the wings spread over forty-five feet
of space.
The motor and operator are in the body of
the bat. This is kind of horizontal cone.
placed on long skates corresponding to the
bats feet on the summit OF which Is 4
screw with sails. The tissue of which are
made the screw and the birds wings, the
wooden nerves to which this tissue is ad-
justed, the silk with which the body is
covered and the filaments of bamboo that
form the double interior, all have been COM
bined, calculated, weighed and Initiated
with a patience of observation and ingen-
uity that is marvellous in the extreme.
The flying machine" is like mechani-
cal bird with bones, flesh and feathers,
animated by the soul of man. The wings
are capable of making all movements made
by the wings of birds. Mr.. Alder has spent
in the construction of his flying machine"
$4,000 and he wants tine municipality of
Paris to lend him the pavilion Of the
Champs-ElyseeS in order that he may demon
strate his theory before sayants OF all
classes.
From tie experiments already made. Mr..
Adler has proven that his bird can rise from
thirty to fifty feet above the earth, and soar
over a distance of 1909 feet in length, but
for the result wished the machine must
have space.
As s,ys Mr.. Alder: 1.-THE vulture, when
lie wishes TO leave earth, steps quick, more
quickly, shaking his wings, and, suddenly.
when speed is acquired. his feet leave the
earth he rises, scars and is borne away by
the atmospherical currents. In the same
way my apparatus Will soar above the
earth"
Doubters ask: Can this machine con-
tinue in motion several hours without a
fixed arrangement for changing and re-
changing the motor that furnishes its
power? What is this motor? Electricity.
But accumulators are impossible. because of
their weight; batteries give only powerful
currents during short time, and even their
weight is not to be despised.
/ am inclined to think that in spite of Mr..
Ader's talent his flying machine" will,
with its present motor, fly only for a short
time.
Soon the heaviest metallic monument, the
Eiffel Tower, will receive the visit of the
Iightest metallic instrument of locomotion,
the balloon called the Francois" Mr..
EQUITIES, a French engineer, thinks he has
discovered the secret of aerial navigation,
and he bids fair TO become formidable
rival of Scoll, Tissandier, Renard and Fest
While the last named replaces gas with
gasoline, while Meusmer congresses the
hydrogen gas, in order 10 give more weight
to his balloon, NJ. EQUITIES does quite the
contrary. He expands the hydrogen, thus
weight; that is, the weight of cubic meter
of air by cubic meter OF expansion. The
interior of the Francois" is divided into
two parts by movable partition that sepa-
rates the hydrogen from the atmospheric
air. When the hydrogen expands under the
action OF steam, from the heating pipe, it
drives out backward the air under the
movable partition, and this air returns TO
the front by the atmospherical pressure as
soon as the hydrogen cools. This action is
called pulsation.
The "Francais" is constructed in this
manner: Two spherical segments of steel
plate are united by their plane section. An
internal armature that follows this section
prevents vertical flattening; tubular axis
with circumference increasing toward the
center joins the two poles and supports
a heating pipe, at the same time
two external extremities of the tuhu-
lar axis are furnished with two
metallic governable sails, which by their
opposition at the vertical ascension and de-
scent. obtained without loss of ballast, pro-
woke horizontal displacement With the
balloon is an apartment for the aerOnauts
and a little rudder behind the balloons
equator permits its turning in all directions.
The only ropes are those used with the rud-
der. the sails and safety guide rope. The
"Francals" Is so arranged that 1t can fail
upon the earth with but little injury, and
four wheels placed under the aeronaut's
apartment facilitate steerage when there is
wind. Every security is given aeronauts in
case of storm, and unlike silken balloons,
difficulty in execution decreases with the
volume.
The little evaporation is in itself marvel.
The fire cannot be seen. A regulator dis
tributes with precision the vapor left in the
heating pipe. and all works automatically.
Perhaps Mr.. EQUITIES may give an idea to
Mr.. Alder, because he hopes to use atmos-
nhprir plpctririty tn mt action a
and store quantity sufficient of the fluid
to make terrible engine of war.
The external metallic surface of a small
balloon collects electricity from the clouds
as it passes. To avoid an explosion while
crossing cloud charged with electricity,
the opposing Francois will discharge its
own by means of wire conductor two or
three hundred yards in length.
This wire, in contact with the earth, can
produce the same effect as lightning, and as
the Francois can be guided. no powder
magazine will be- able to escape in time of
war. BARONESS ALTHEA SALVADOR.
