In
all projects of this kind the problem which has given most trouble to
inventors has been to overcome the induction. In other words, electric
currents will leave their original conductors and pass to other
conductors which may be near at hand. This interchange of currents may
take place without seriously hindering ordinary telegraphy, as the
indicators are not delicate enough to detect the induction. When
telephones came into use, however, the induction became a great source
of trouble to electricians, it often being the case that the sounds
and influences from without were sufficient to drown out sounds in a
telephone. To-day's experiment was conducted by Mr. J.F. Shorey, a
well-known electrician, who exhibited Dr. Orazio Lugo's cables for
electric light, telephone, and telegraphic purposes.
A large number of prominent electricians were present, including the
following: General J.H. Wilson, President of the N.Y. and N.E.
Railroad, of Boston; Messrs. Frank L Pope, S.L.M Barlow, George B.
Post, Charles G. Francklyn, Col. J.F. Casey, W.H. Bradford, and Selim
R. Grant, of New York; James Gamble, General Manager of the Mutual
Union Telegraph Co.; T.E. Cornich and W.D. Sargent, of the Bell
Telegraph Co.; S.S. Garwood and J.E. Zeublen, of the Western Union,
and others.
