in the history of wireless telegraphy
by A. Frederick Collins, it is pointed
out at least 1000 years before Christ
the question was at issue whether the
instellar space was filled with sub

Huygens struck the first practical

succeeded IN establishing the fact of
an 6il-pervading medium. Faraday
was followed by James Clark Maxwell,
who. in 1861, systemaized Faraday's
conception with his electromagnetic
theory % light, a theory which means
that.liglt electricity. and magnetism
are Transmitted by the same ether at
an Identical rate of speed.
Ire next step toward wireless COM

employ ne Term electric radiation. He
used lie ERIN, Collins points out, TO
describe the waves emitted from a
LcyGen jar. They have been called
Hertzian waves ever since. Before
Hertzs discovery Prof. Joseph Henry,
of Washington, D. c., had succeeded in

came the effort TO produce electric dis
charges. Sparks were produced as ear
by as 1902, but they were so small
that II ey could be barely seen with
the naked eye. In 1916 came the dis
eovery and development of a jar in
which electricity could be stored-the
Leyden jar. Then the sparks began to
fly, and with them, the certainty amoug
