FROM the foregoing chapter, while it may be
rightly inferred that power is the true secret of
aeroplane flight, it is desirable to point out certain
other things which must be considered.
with a machine in horizontal translation, is impossible,
unless it is done by taking into account
the factor due to momentum and the element
attributable to the lift of the plane itself due to its
impact against the atmosphere
To determine this, short of actual experiments
with a machine in horizontal translation, is impossible,
unless it is done by taking into account
the factor due to momentum and the element
attributable to the lift of the plane itself due to its
impact against the atmosphere.
The shock to the public was tremendous. Many insisted that the cable
had never been operated and that the entire affair was a hoax. This
was quickly disproved. Aside from the messages between Queen and
President many news messages had gone over the cable and it had proved
of great value to the British Government. The Indian mutiny had been
in progress and regiments in Canada had received orders by mail to
sail for India. News reached England that the mutiny was at an end,
and the cable enabled the Government to countermand the orders, thus
saving a quarter of a million dollars that would have been expended in
transporting the troops.
GLIDING FLIGHT.–The earliest attempt to fly
by gliding is attributed to Oliver, a Monk of
Malmesbury who, in 1065 prepared artificial
wings, and with them jumped from a tower, being
injured in the experiment.
MECHANISM DEVOID OF INTELLIGENCE.–The great
error, however, in seeking to copy nature”s form
in a flying machine is, that we cannot invest the
mechanism with that which the bird has, namely,
a guiding intelligence to direct it instinctively, as
the flying creature does.

importance in connection with the telegraph was the automatic
transmitter
The invention of Wheatstone”s which proved to be of greatest lasting
importance in connection with the telegraph was the automatic
transmitter. By this system the message is first punched in a strip of
paper which, when passed through the sending instrument, transmits the
message. By this means he was able to send messages at the rate of one
hundred words a minute. This automatic transmitter is much used for
press telegrams where duplicate messages are to be sent to various
points.
