INVENTOR EnIS0N'S LAST.

am very sorry, said Mr.. Edison,
the inventor of many more than seven
wonders, 81 Il World reporter who called
upon him at Menlo Park Yesterday.

This was a great disappointment to
the reporter, for from what he had

courteous gcntlcmen Ill the world, I'M

machine which, placed upon loromo-

in slant tones, that can I've heard for
miles, F." am engine Marmadukc, and
will stop at Boontou Station, or what
soevcr other warnisg or information 1t
chooses, there is not the least reason to

Edison can make whatsoever he likes,
and even without the mcagre cxplana-
ton Of this his latest wonder, which the
reporter is herewith able 10 give no
person who has ever met him on visited

smiling upon the pernexed reporter,

this thing will utter Words which can

With u is for the present, the reporter
had to content himself, Mr.. Edison first
having called his attention 10 the inn

coasts, from which, by It's aid, the keep

way down stairs To II machine shop,
where eight busy machinists were in

network Of leather bands, attached Ia

"Ah, here tits, said he, picking up
II circular piece of brass, The surface OF
