turn availed themselves Of his services.
and, his inventive faculties getting full
play. he took out over fifty different
patents in connection with improve.
mems in telegraphy. In 1876 tho Wiz
ard established his laboratory at Menle
Park. in New Jersey. from whence be
has given invention after invention tc
an astonishcd world.
Nearly all these inventions. which
number about three hundred, were to be
seen at the Paris Exposition. Never be.
fore had such . collection Of the great
inventors triumphs been brought to
gcther. They were exhibited with the
object Of tracing the history Of his numer
GUS inventions and Of showing their pres.
ent perfected state. Mr.. Edison'e exhibit

sending men to different parts OF the
world with the view Of discovering
something which will still further per.
feet his carbon.
Next. there was the telephone depart
ment showing what Mr.. Edison has
done, from his original instrument down
to his latest improved photograph or
loud-spcaking telephone. Mr.. Edison
has devoted large amount Of his time,
and energies to pcrfecting the tclc-
phone. and here we have his multiple
telephone, his autographic telephone.
and many others, including his wonder
ful automatic telephone, which is
capable OF transmitting words at the
lightning speed Of 1900 per minute.
Then there was tho telegraph depart
ment. which shows among other things
that marvellous train system of tele-
graphing-by which messages are sent
from train travelling at fifty miles an
hour on q track fifty feet from tho tele-
graph wires.
The photographic department was
perhaps tho most interesting Of all.
When ten years ago Mr.. Edison de-
clarcd that he had conceived and i'm
perfectly constructed q machine which
could distinctly repeat any sound that
might be produced from symphony in
Wagner to the squall Of one-year-old
baby. the world took to laughing. To-
day. however. his factories are turning
out forty perfected machines day. and
some l.s0O are already in use in various
business houses. Mr.. Edison has since
created q pocket phonograph, the
cy y.inder of which will take some three
hundred words-about the length of an
ordinary letter. One Of these is now in
use at tho New York World Office. The
machine is placed downstairs. The
reporters come in and talk into it. The
cylinder is then taken up stairs to tho
composing-room, and the compositors
set up from its dictation. not only at
tanning o greater speed than on the old
system. but earning moro money.
Mr.. Edison speaks very confidently Of
his new orc-extracting machine, which
promises to revolutionize the mining Of
ore. The machine by very Simple
process separates the ore from tho earth.
and leaves it ready for the furnace. As
yct 1t Is only adapted to iron ore, but
the Wizard is now studying the question
OF q machine for dealing with both re-
fractory silver and gold ore, and he will
probably get them out in the near fut-
urc.
Tho .far-sight machine" also prom.
iscs to be big thing. but it is absurd to
say that 1t will enable o man to see his
wife two thousand miles away. In a
city. however. it will be OF practical use
and for tho present. at least. the Wizard
does not look for any thing further.
Among some fifty-fvo yet moro extra
ordinary inventions in progress in MIR
Edison's laboratory Is ono which con
Germs aerial navigation. and it is not un.
likely that the next great revelation Of
science will he in that direction.
