PREsCOTT's PROCESS.
Wednesday afternoon last, at the
Broadway office of the Western Union
Telegraph Company. test was made
of an invention which promises to be
Of almost more Importance to the pres

be simultaneously sent on single wire
in opposite directions. and with no
more liability to mistake tn n as if an
equal number of wires were used To
make the matter clear it will be neces.
sary to look little backward Morse
took the first step in te'egraphy-and
the first is always the greatest-by the
invention of system by which mes
sages could be sent between ahy two
terminal PORTS, and dropped at any
way station on the circuit. The OBJ
lection to his system was that the
transmission of single message occu
pied a wire entirely. And though
electricians were convinced that a DIFF
f elt result could be attained, no one
sho eed how it could tie done until So
recently as three Years ago, when Mr..
j. b. Steans invented
