Back Of these eues.lons shere lee
one OF the most aaioundirl pozdhlli-
ties OF the immediate fuNre. The
thought has rot been conjursl Up b.
lha fovered imagining of sorie hectic
brain, but nB d matter of fact Is based
on some very concrete experiments
which atow remarkable promise o. sue
Gees within a shorter time than ~
really imaginable.
We are all more or less familiar In q
general way wlth tho fact that photo
graphs can be transmitted over die
tsnccs by means Of telegraph llnes. ead
even through the fundamentally o.
radio. IN fhir case. however. wo need
