Electricity is the good genius of this
century. Those who know most about
it say that what we have done with IL
in the past is but trifie compared
with what we may hope TO do with il
in the future There are people who
expect some day TO be .able TO call Il
distant friend by wire, see his image
in mirror. hear his voice. and. If de
sired, get his exact signature to sub
scription paper or check.
These things may all come. At
present we get along with an inter-
mittent and exasrrating repetition of
the voice over the wire, having no
meass OF determining the identity OF
our interlocutor, no certainty Of get
ting his words accurately and no
record OF what hc says. Gases are rc>

Mr.. Grty's device consists Of two
current intcrrupteis at the sending end
and IA pair of electro motors ut the ie-
ceiving end. The sender uses either
pen or pencil, near the point of which
are attached two threads running vi
right angles to each other. These
threads are kept at an even tension
automatically, and each one passes to
current intcrruptor set into the telo
