THE HELIOGRAPHINWAR
A System OF Great Importance In
Military Science.
How Messages Arc Flashed Over Great
Distances by the Aid OF This Unique
Invention - The Old Method
OF Communication.

OI GI10 re-
cent troubles over the late lamented
Geronimo, made what might have been
termed n photographic survey of the
seat of the Indian troubles, and located
on the maps the available points of OBJ
servations with the direction and COM
pass bearing of the other visible sta
tons. In this way the country was
covered with network of Photograph
lists, and the observers Mt each station
kept flashing into headquarters the
latest movements of the hostiles.
The Indians, under this cross-6re of
mysterious sun signals, decided that
the devil was in league with the troop
crs, and their supcrstitiOuI fears, added
to the constant marrying from the
widcly-scattcrcd parties of cavalry,
brought them to terms, Us never could
have been done but for the use of the
fash signals.
The Gi3tC noes covered by some of the
Photograph stations were remarkable.
Fifty Or sixty miles were considered
nothing unusual, and on one reach
one hundred and twenty-five miles
were covered without an intervening
station.
The invention of the telegraph be-
longs tc England, and it has been used
extensively in her service iii India and
Egypt, two countries where the ntnos-
phcric conditions are very much as in
our own arid west. The instrument
was first brought to America in 1874,
and. like y Ercatmany other Inventions
OF John Eull. was greatly improved by
his Yankee cousin. so that IhC in6tru-
nncrt now in use IL our signal corps is
considered Dy exports the most nearly
perfect IL Tao world.
The speed Of the photograph is not so
great as that 81 the regular telegraph
Instrument. although the Morse alpha
bet is used. Ten or twelve words q
minute is considered good work, and is
Il vast Improvement over the old
method Of signaling by flags, with
which from three to four words min
ute was the most that could DC done.
An ally of the photograph now in use
by the signal corPI is the flash lantern,
where messages arc sent at night over
stretches of from ten to fifteen miles,
though. under favorable conditions,
with night glasses. the messages have
been sent forty miles at single reach.
The old method in night signaling was
to use two torches after the manner Of
lag signals. One of these, known as
the foot torch, was placed on the
ground in front Of the observer, to give
his location to the receiver at the other
end of the line, and the "hy torch" on
the end of the long pole was used in
waving out the words
This method was nfterward super
scdcd by the use of lanterns with dark
shutters worked by key, as in the
telegraph soundcr, but these arrange
ments were likely to get out Of order
in the field, and now the energies of
the corps are bent to perfecting n bril-
liant lantern of light weight, which
can be obscured by regular hello
graph screen. The lanterns now in
use in the corps are fed with mixture
of kerosene and sperm oil, but expert
mcnts are now going on with a mag
ncsium tape, fed before the reflector by
clocllworl1. 1t gives very brilliant
light at an expense of about fifty cents
an hour.
The Photograph is regarded by army
officers as one of the most practical
and useful inventions of modern mill
tary science, and in the case of be-
leagucred city would furnish q means
of communication with the outsida
world that would discount balloons,
carrier pigeons and the magnetic tel
| cgraph, rs the line could not be cut by
the enemy and the messenger could
not be captured or shot in transit. In
the case Of Washington, should that
city ever chance to be blocaded, the
Photograph would furnish very GER
tain means of communication for
radius of thirty miles around, and
signal observer stationed ON top of the
monument could fash messages almost
is not quite to Baltimore, If the con-
litions were at all favorable.
