Edison here drew a waving, curying line.

it is simply impossible for me to pick
out the real message. Yet those fellows
do it every time, and with comparative
ease."
Cable operators ought to feel compli-
mented by what MI. Edison has to say
OF their skill in cabling. One would
think he who was accredited to be one
of the most skillful telegraphers of his
time might at least claim some pro-
ficiency in this other branch of the SER
vice. Yet he acknowledges the superior
ity of men whose work is seldom noticed
beside the more theatrical feats of the
ordinary land wire operators.
SEEING BY TELEGRAPH.

Do you think this is coming adjunct of
the telephone?'' was the next question.
Much has been said about it in the dailies,'
he replied. They tell how it is to be ac-
complished by selenium, but do not see
how it is practical l do not think The Sc
enium pl ocess will solve it. 1t is surprise
to me, however, that the Transformation of
pictures by wire is not more used. 1t is
very easy of accomplishment, and news
papers could get accurate pictures of dis
tant events in this manner. l have trans
mitted pictures this way, and would guar
antee to send one ten inches square dis
tance of five hundred miles every ten min
utes. And every picture would be as good
as the average newspaper cut at that.
HERE'S ANOTHER MARVEL.

system of signaling between moving trains

propose to do it between ships at sea, and
even when they are thirty miles apart it
could be accomplished. One ship might take
"a message far out to sea, then transmit it
to anoth her vessel thirty miles distant, The
