liver message at
the rate OF 1000 words minute, says
New York World.
This means that $4,000 messages OF
70 words each can be sent every dag
from New York to Chicago. Mr.. De-
1any has figured it out that at five cents
for each message of seventy Woros
there would be a satisfactory pront 10
the telegraph companies. The TWO
cents which the government receives
for forwarding a letter is almost equal
" divided between the cost OF railway
conveyance and local delivery Of the
letter. The cost of transmitting the
words of letters at the rate OF z,Ooo
words a minute. if the government
should do the telegraphing, would Dc
insignificant. and therefore the outla!
of the government would not be nm
tied to one cent for local delivery. Inis
being so, the possibility of a, 10 WoHd
letter delivered 1000 miles away III
one hour for one cent at once becomes
attractive.
Mr. Delany's instrument is known as
the chemical telegraph and has ne9n
in existence in a crude form for many
I wears. 1t has long been known thae d
sensitized ribbon would indicate an
electrical impulse fifty times quicker
than an electro-magnet such as is used
! in an ordinary telegraph receiver. A

a before the New York Electrical society
