Newspaper Man Tells of Wonderful De- veIopment of Invention of Young Italian Inventor at New
 Exchange Hotel.

w A. Ryan of New York, who is rep resenting the interests of the Marconi Wireless Telegraph Company of Can
 ada. Ltd, spoke to a large audience of prominent Montgomerians last night In
 the new dining hall of the Exchange Hotel on the past and the possibilities of the great invention of the young Italian genius.

 waves. although they travel through the ether at the same speed as light
 waves. These waves dre known to science as Hertzian waves after the scientist who first demonstrated their existence
 Tt was Hertz and Clerk Maxwell who proved the identity of light and electricity. This discovery and the
 knowledge of how to produce and de tect certain previously unknown ether waves, made possible this new means of communication.
 Superior to Wire Telegraph.
 '.In my lecture next Monday evening
 al the new High School auditorium 1
 uropose to demonstrate by means of
 Marconi instruments the superiority of thh wireless over the wire telegraph
 We will show that it is practicable to
 send messages directly through such
 solid substances as brick and stone
 walls without the aid of a connected conducting medium; we will prove that fbis new system is applicable to any
 of the ordinary uses to which the wire
 telegraph is applied and will show how
 much more economical the wireless sys-
 tenn is than the systems employing
 wires.
 this Is accomplished we must ask the
 reader to accept as an established fact
 the existence In everything, around and
 about and through everything that Is
