Remarkable Whispering Telephone.

The dictograph is the latest in telephones. One can stand 10 feet away and whisper a message, or when 30 feet distant speak m an ordinary tone of voice and the message will be clearly and audibly transmitted. Its construction is a secret of the inventor. It can very easily be used by an employer for dictating to a short-hand writer, as the latter could take the dictation at any distance from the speaker, without having to hold a receiver to the ear. It, of course, works both ways, allowing both persons to converse equally well. This explains the name " dictograph." In detective work it promises to prove an exceedingly valuable adjunct. Where a third party is desired to hear an interview between two others it will no longer be necessary for the witness to hide behind screens and in other

inconvenient places. The dictograph can be hung behind a picture or under a desk, or even placed in. a partly opened drawer of the desk, and will transmit faithfully the entire conversation to one or more witnesses in another room, or to a stenographer.
