None are more sensitive than the

Tor mat reason my acoustiphone should
appeal to them moro than any other
similar Invention. 1t 70 SO simple that
u can be used without attracting the
aeast attention either at home, in the
theatre or in any public place.
Another thing that my invention DOS
sesses. and which Is lacked by all its
predecessors In the field. Is the property
OF not only transmitting sound, but OF
giving the listener, though he be stone
deaf an exact idea OF the distance
passed by the sound waves.

Mr.. Pape explained to The Evening
World reporter that the transmitting
portion OF his apparatus might be con-
cealed In the pocket and at the same
time pick up sounds from a considerable
distance. In q pamphlet prepared by
Mr.. Pape he tells Of other uses 10 which
his aooustphone can be put, as follows:
ITS secret installation as by and de-
tectve IN the wall or floor Of an ad-
Joining o where 1t Is suspected some
nruel rather or mother IL abusing his or |
her children by treating them with CRU
city, or some cowardly wife-beater, |
whose poor victim Is locked up by him, |
OF who has not courage or wisdom
enough to report the matter to the Do
lice. will make q splendid instrument In
the hands of the authorities. Perhaps
two crooks or firebugs meet ana hold a
rendezvous planning a great robbery or
other crime
THE acoustiphone might lie at their
very feet and they would have no idea
that 1t heard even their faintest whis-
per n transmitted 1t to a listener
far removed from them. 1t might be
dropped down a chimney from the roof
Of the house. 1t woul only be necessary
to lower it near the frehole Of the room
or apartment to hear distinctly every
word Of conversation.
Check on burglars.
TT will no longer be necessary to
''alt for news that our next door neigh
Dor has been robbed and killed, for
my acoustiphones can be 30 arranged
that the hrst warning OF violence may
mediate ne~ighborhood."
In his enthusiasm over his invention
Mr. Pape does not consider that acous-
tiphones arranged as he uggests might
prove embarrassing for families who
desired privacy from their neighbors.
In his verbal illustration he asserts that
u a tenant Of an apartment-house liv-
what was going on In the kitchen on
sary to drop the transmitter down the
dumbwaiter shaft.
In fact, whom he p~erfects the wireless
attachment for his acoustiphone Il
would be possible for a wife to slip a
transmitter in The pocket of her hus-
band when he goes to work and keep
herself informed through tho receiver
of his every audible action. II fact,
there would be no such thing possible
as private conversation where the
curious could introduce and conceal one
Of these all-hearing transmitters.
Mr.. Pape has his invention fully COW
cred by, patents. and expects to launch
It or the market as soon - he has
