The MAGNETIC TELEGRAPH. The facility
with which intelligence is communicated,
without respect TO distance, by Morse's Tele-
graph, is trny astonishing. We have Just seen
dialogue carried on between New York city
and FIVE other cities, extending as far as Buffa-
10, and the questions proposed were all an
swered by each of these cities in less than five
minutes. We have seen question returned
in one minute and a half In very short time
we shall have intelligence from New Orleans
as quick as that The United States Gazette
says measures have been adopted for extending
the wire OF the telegraph to New Orleans, and
arrangements have been made for setting the
posts and stretching the wires. So Boston
folks will be able TO converse with their New
Orleans friends at any hour. This will not
only give US immediate intelligence Of import
ant war operations in that section, but it will
greatly facilitate business transactions.
