Mr.. Marconi's friends in this country
celebrated his achievements in the Astor
Gallery Of the Waldorf Astoria last even
ing. where Mr.. Marconi was the guest Of
honor at the annual dinner OF the Ameri
can Institute OF Electrical Engineers.
About 800 people, including many women,
sat at round tables below the speakers
dais. The decorations Of the room had
been arranged In compliment to the in
ventor and when the ices came In they
were borne by the walters on large trays
surmounted by telegraph poles with seq
ments OF wire hanging from them-pos-
sibly a covert joke upon the possibility
of Mr.. Marconis inventions freezing out
the ordinary telegraphy.
The walters marched In a sinuous course
among the tables, led by the head waiter.
with these CONNECTIONS. Every one ap-
plsuded the parade, and simultaneously
there was an electric display all about the
room. At one end Of the room the name
Of st. Johns blazed in electric Lights; at
the opposite end tho name Poldhu, and be-
tween these the electric current played
like a lambcnt fame along cables. upon
which at intervals were three dots, or
more particularly, three very small incan-
descent lights in group. the experimental
letter IS" which Marconi flashed from
Cornwall to Newfoundland.
MIR. Marconi. in very interesting speech,
which held the closest attention OF every
one in the room. not only described some
thing of what he had done and what his
aims were, but let 1t be known that accord
ing to his first intention these transatlantic
experiments were to have been made be-
tween England and the United States. In
stead OF England and Newfoundland.
Among those seated with the President
Of the Institute. Charles p. Steinmetz, and
Mr.. Marconi at the speakers table were
Prof. Elihu Thomson, Prof Alexander
Graham Bell, Prof, Y. B. Crocker. DR. NJ. l.

who acted as toastmaster after an intro
duction by President Steinmetz; c. w.
Price, Carl Herring and F. j. Sprague.
Mr.. Aarconi, in his address. expressed
his thanks and gratitude for the great
reception and said that he was highly
honored 10 be entertained by such an i'm
portant body, as it WAS well known all over
the world that America stands FIRST in
electrical engineering. He felt deeply the
compliment Of being honored by men whose
names were household words all over the
world.
