The three patents referred to US last
week are first The Cray harmonic

supptred tn he equal in value to the
Edison duplex and qladruple1 system.
II shall lie remembered that Elisha
GRAY. Of Chicago. while experimenting
a frS years ago for a telephone. found
that the several sounds OF the musical

the Morse letters the circuit is after
nately opened and closed. and a duplI-
cate of the message appears on a m

Leggo says thai in recent experiments,
between this city and Boston, over an
ordinary wire, a rate OF transmlssiCn
Of 8, 800 words per minute had been
demonstrated and that the ANTICIPATED:
rate is 5000 words. the price pail
for the Leggo rights is said to have
been $1,000, 900.
La its prosp, ctus the company claims
to be able to do more business with
80. 900 miles of wire than is now done
with $50, 900, and at q cost of mamie
nance, construction, and equipment
less by four fifths than is now the rule.
The third great invention is a new
way of manufacturing wire. It's com

The conductivlty Of such wire
is, its capacity for carrying an
current over great distances
rs compared with the ordinary wire Is
represented to be as 100 to II. 1t IS
estimated that fully rs per cent. will
be saved in the cost of repairs and re-

One improvement is prolnised--which
