A NEW WIRELESS TELEGRAPH.
Professor W. 8. Johnson and C. L
Fortier, of Milwaukee, have made a successful test at Chicago of the wireless telegraph. The succeeded in telegraphiDg through a suite' of seven rooms without wires, with all doors closed and through seven walls. Another test was made when the signals were conveyed through three fireproof vaults and an ordinary telegraph switchboard, in which 3D wires w«sre connected up and forty dead ones were located. Notwithstanding the fact that this switchboard contained live wires the current pa3=ed through all of the vaults and through this board. A third test was made in which the sending instrument was placed inside of one of the steel vaults and both doors were closed and the combina f iori lock turned. The signals were than transmitted clearly from the inside of the vault to an adjoining room. The professor claims that his invention is materially different from that of Marconi and that instruments can be constructed to be carried on horseback and be ready for operation within a few moments ifter they have reached their destination . The sending instrument used was intended only for short distances. The receiving instrument, however, was • complete, and ready for use at aay distance.
