made from Niagara Falls acetylene
gas smoke, and most of the green ink
is green color mixed in white zinc

Long Distance Speaking Without
Wires.
Experiments have been conducted
for some time past near Chepstow for
the transmission of the human voice
over long distances with the aid alone
of the natural elements. The inventor
Mr.. Grindell Hattheys, it is stated,
submitted his discovery recently to a
severe test in the presence of a num-
Der of experts. He was placed in the
strong room Of a big London COM
mercial house and locked in, with nine
inches of armor steel, nine inches of
fire brick and six feet of concrete be-
tween him and the outer world. By
means of his small portable apparatus
he carried on conversation with an
operator in another room on the far
Their side of the buildina So distinct
and faithful was the transmission that
the experts in attendance were actu-
ally able to hear the tick of his watch,
Notwithstanding the almost impene-
trable mass between the two instru-
ments. The inventor contemplates a
further test through five miles of solid
rock between Chepstow and Tintern.
He is engaged in long distance tests
in connection with the War Office and
on Sept. 9, 1911, spoke. from Beachley,
in Worcestershire, to a point over
Ave and one-half miles away near the
Seven Tunnel outlet on the opposite
side of the river. He intends to carry
on experiments between Chesptow and
Cardiff, about twenty-five miles. If
he does this successfully he is to go to
Aldershot to conduct some final nego-
tiations for the transfer of his rights
in the Unighted Kingdom to the
government. Speaking to a represent
alive of the Western Mail published at
Cardiff, the inventor stated:
Vibrations produced in the air by
his apparatus did not take the form
of the HertZian waves, as in the Mar
conf system of wireless biography. In
fact, they were not waves at all, mas
much as the disturbances were of such
high frequency that there was no ap-
preciable break between them: and
their action was rather continuous
than fitful and separate, as in the case
of Hertzian waves. 1t was this high
frequency produced by his apparatus
that had made 1t possible for sounds
to be reproduced and for all the f1uc-
tations and intonations of human
speech to be transmitted so faithfully
that the voice of the speaker could
be recognized. AS in the cinemato-
graphic picture, each delineation ran
so quickly into the other that. con-
tinuous sustained reproduction was the
result.
The inventor has named his instru-
ment the aerophone. A complete set
of instruments for a mile radius
would cost about $48. It is possible
this system to carry on long
conversations, and each speaker can
distinguish the voice of the person he
is talking with. No expert knowledge,
it is claimed, is required to operate
the system, as the box with the instru
ment would be self contained includ-
ing the battery, motor, transformer
and everything else necessary for
