SENDING POWER THROUGH AIR.

A hundred developments Of the wireless principle
are fast reaching perfection. The most important
one is the sending of directive power through the
air. When power in quantity be transmitted
zhe success OF the aeroplane freight and passen-
ger transporter VIII be assured. No electric rail
road monocycle travelling at a hundred and
fifty miles hour viii be able 10 compete with
the aerial express driven by the power Of Niagara

the unmeted air by an engineer sitting in his Office
thousands OF miles away The sky paths will be
charted with mathematical accuracy and the only
bumps in the roadbed VIII be caused by sudden
rises TO compass mountain peaks. Passengers may
be warned 10 put on their Overcoats when nearing
such elevations. The three-hour route between New
York and Chicago Wi be double tracked for the
sake OF avoiding collisions, track d thousand
feet above the other, and passengers On the upper
track may be requested not 10 throw cigar ends
overheard because they might light on peoples
heads going the other way.

vehicle An important detail is the travelling

the etheric current The lack Of continuous ground
contact has hitherto interfered with connections

st possible for railroad signals 10 be operated at
any distance
Torpedoes and trains be guided and steam
ships steered at distance. II IS Imaginable that

POCKET TELEPHONES FOR ALL.
