We answer the New York Herald that the At
prophecy not of what was seen dmly eighteen
hundred years ago on the island of Patmos, but by
what seen clearly fifteen years ago through the
lights Of science, recorded at that time by Profess
Morse Yes it is very clear that Professor Morse
prophet; and it is something that he is living
to realize the correctness Of his differences from
this law" which are now completely fulfilled amidst
the rejoicings Of the American people. Surely Mr..
Morse is aprophct.
We publish the following letter written by Pro-
fessor Morse, just fifteen Sears ago yesterday, to
Hon. John G. Spencer, then Secretary of the Treas
ury on the subject Of magnetic experiments
between this city and Baltimore, and expressly pre-
dieting the laying Of the submarine cable:
NHw York, August 10th, ls43
SIR take this opportunity Of communicating to
the honorable Secretary the result of the experiments
made on the 9Th inst with the prepared wire in one con-
tinuous line of l60 miles. Professors Renwick Draper
Ele and Schacfer with my assistants Professors Fisher
and Gale, present by invitation Professors Sl
man. Henry, TOrrey, and DIR. Chiffon also invited
but wec prevented by official duties from attending.
In the letter to the honorable Secretary dated March
10th, l843, in which propose my general pan have
this remark speaking Of the wire after its insulating
preparation should be completed Many interesting
experiments bearing upon the general result then be
tried before the wire is enclosed
The experiments alluded to tried on Tuesday and
with perfect success had prepared gavanc battery
of 800 pairs in order TO have ample power at command
but to my great qualification found thnt 100 pairs
were sufficient 10 produce all the effects desired through
tho whole distance Of LOO miles.
t may be we'll to observe that tho 160 miles Of wire
are to be divided into four lengths of 40 miles each form
ing fourfold cord from Washington Baltimore Two
wires form circuit the electricity therefore, IN pro
ducing its effects at Washington from Baltimore passes
from Baltimore to Washington and back again to Bat-
more Of course travelling 80 miles to produce its result
Ono hundred and sixty miles, therefore, gives
tua distance of 80 miles, double the distance from Wash
ington to Baltimore The result, then, Of my expert
ments on Tuesday that battery of only 100 pairs at
Washington will operate telegraph my plan 80 miles
distant with certainty and without requiring any inter
mediate station u
Some careful experiments on the decomposing power
at various distances made, from which the law Of
propulsion has been deduccd, verifying the results OF
Ohm and those which made in the summer of 1912,
and alluded to in my letter to the Hon. c. G. Ferris and
published In the House report NO IL OF the last Con-
gross. se A6
The practical inference from this iaW is Got tlgrapht
communication on the cicero magnetic p poy ,ch crrfzny b
established across the Atlantic ocean Sqrfy this may
scp am confident 1s time wiH whe this project wA b
realized.
The wire IL now in its last process Of preparation for
enclosing In the lead tube, which will be commenced
Tuesday the 10th inst
have the honor to be, sir with sincere respect your
most obedient servant,
SAMUEL f. b. MORSE,
Superintendept Of Electro Magnetic Telegraph.
