As a Detective,
Perhaps the most startling of the
possible applications of the loud-talk-
ing telephone will be as spy and de-
tective, You can manipulate com
binations of crime and dark dealings
all day long wherein the haut- parleur
will be the hero. Two swell crooks
hold rendezvous in the room of a
hotel and plan safe-cracking cam

some time ago by the Ministere des
Postes ct Telegraphs, with the re-
suit that it has been adopted by the
state to some extent. Inside the
transmitter of this instrument there
are delicate membranes of silicate
of potash and magnesium, which are
extremely sensitive to every vibra-
ton of sound-waves. The ordinary
induction coil. such as Is used in
the state telephones, completes the
