Prof. A. Graham Boil; the inventor of
the telephone, comes from the staid old
city Of the witchee-Salem., He is pro-
fesaor of "vocal physiology" in the Bos-
ton University. About five yeara ago he
frat began to think about the possibility
Of the transmission ofsound by telegraph,
and the idea took possession of him COM
pletely. His invention had 60 far taken
form eighteen months ago, and with the
assistance of practical electrician, Mr..
Thomas A. Watson. he began to expert
nsent, using for the purpose wire De-
tween Bos.on and Cambridge, about two
niles long. The success OF the inyen.
tion was TO him from the first only
question or time. He had "got 1t down
sfine," % the boys say and the successive
experiments were only SO many steps to-
ward rendering the instrument practical
for general use. f. eil ,t,,t',.,,..
The first Gme the practical success of
satisfaction of Others were on October 8,
shs DriSa.s wire Gf the HaiTorth Asanu-
featuring Company of Cambridge. Tho
telephone then spoke for itself, and the
conversation Of the operator in Cam.
bridge could be distinctly heard ct the
Boston end of the line. An interesting
dialogue took place, tho speakers talking
In their ordinary key. The experiments
were continued almost constantly. Prof.
Bell and Mr.. Watson conducted their
operations in .he fifth story of lodging
hoube tn Exeter ttslace, in this. city, and
wore exceedingly careful, whom they sd-
mitted to their E0oms. L found my way
| up there to-day, and had On interesting
| chat with Mr., Watson, who seems to be
q bright young man, and is very enthusi-
astic concerning thetelephone. He said
| : that Prof Bell was the sole inventor of
the instrument, and no other human be.
| ing had ever tackled the idea. Tho Grst
patent was taken out about o year ago,
and several had been obtained subse-
quently. Mr.. Watson gave ali interest
;;a;fssl ;as :..;s:saslnt of the recent experiments
with the machine, most of which have
been over the Eastern Railroad Compa-
ny's wire between Salem and Boston,
The titae selected for these experiments

there Is then less probability Of tho wire
being Ia use. .-lqd Hoti's +, ,df = ;fr,.!
One of the experiments, which eecur-
red on January'2l was eminensly graft
flying in its results. Not only every word
spoken in Boston, but even the tones and

enFately transmitted and readily rec0g-
nized by those a6 the Salem end of the
lite. Other experiments demonstrated

"The Inst Rose OF Summer" and every

eter place. Boston. The sound was per-

aThe greatest distance that has been
vAnquished by the TELEPHONE is 143 miles
from Boston to North Conway, N. Fl.
The most recent improvements made on
the Instrument do away with batteries
altogether, and permanent magnets are

Regarded as very important step in ad-
vance, as the bother and expense of
keeping batteries in order has been the
greatest drawback to the employment Of
the instrument for private purposes. Tho
honor of having received the first news
paper dispatch belongs to The Boston Globe.
A report Of a.lecture by Prof. Bell in
Salem was transmitted verbally to it last
Monday night. This lecture was about
