when viewed by the visiting delega-

last week end to the Long Island
plauts of the Radio Corporation of
America.
The installation of the Marconi
beam having been completed almost
simultaneously with the recent arriv
al of Guglielmo Marconi on these
shores, it had been in operation less
than "a hours before the group ot
foreign treaty makers and accom-
panying officials and writers arrived
at RiVerEead by special train. Its
log was studied carefully. while those
/ who are working with the SO-called
American beam were piled with ques-
tions.
Although not yet opened for regu-
lar commercial traffic, the Marconi
beam station, known at WAJ and
operating on 22.24 meters, with IA
,lilowatts of power, had sent press
messages up 10 $50 words per min

rectional arc is no more than de-

as do ordinary radio waves. Marconi
has claimed that the automatic trans
mission has a present limit of $50
words per minute, but that laboratory
tests in England indicate it will be
speeded up to 1000 words. The vari-
alton from it's frequency, or wave
length, never was more than go

The American beam. likewise on
short waves, is expected 10 prove
more economical than the Marconi.

was still in an experimental stage, its
developers evinced a reluctance to
talk much about it, except to point
out that the use of the plain 60-foot
telegraph poles with their anten-
nae made it's installation much less
expensive and intricate than the Mar
conf and more easily capable of in
stallation at many more different
points.
