IN THE NAVY.
How They May Be Used for the Purpose Of
Spying on the Enemy Great Aid
to the Admira1s Of Fleets.

Balloons are going to play an i'm
portant part in the work of our navy
around Cuba, and each day of delayed
action will make them more needful
in observing the Spaniard's strength
sned lines of defense. - d.
The tortuous waterways and the
generally land-lockeds nature of the
harbors, their narrow fortified en-
frances, and the excellent retreats the
wide reaches of water offer to their
ships make it imperative that we have
some fairly safe and reliable means OF
making reconnoissances of the Span
iards' positions. The fighting tops,
yes, even the mastheads, are of little
avail for observation at the distances
imposed by the watchful batteries OF
the enemy, and the captive balloon
alone solves the difficulty. This is es-
pecially so where high promontories
like those of Santiago de Cuba and San
Juan completely shut out the harbor
from view and make hitting fleet
therin mere guesswork. Recent expert
ments in Germany, France and Rus
sia have emphasized the Importance OF
the captive balloon in widening fleets
powers of observation, just in the same
way that the ptive balloon will serve
the army; and the patient trials and
study of the Germans have evolved
curious aerostat that by virtue Of it's
shape and peculiar properties is es-
pecially we'll adapted to the greater
range of naval work, and it is quite
safe to say our own balloons will en-
body the general features of the Ger
man design.
The balloons will really be three bal
looms acting in concert The first and
largest is like an immense sausage,
ard bears the main burden of the load
ed car. The second is somewhat SINH
lar in shape, but hugs the lower end
of the big balloon like M creeping
caterpil illar.e This second and smaller
balloon acts principally in the capacity
Of rudder, and aids materially in
holding the balloon in peculiar posi-
tion, while the third and small spheri-
cal balloon trails along independently
behind at some distance and serves in
the same steadying capacity that a
kites tail does. In action, this. triple
balloon floats with great steadiness or
immobility when not under way
something impossible in the pear
shaped affair familiar to all of us.
The observation car is pendant from
the main balloon, which poises in the
air at an angle of about 45 degrees,
practically like the position OF the kite
common to every school boy, and it
is just in that way that the force of
the wind is utilized to increase the
balloons, buoyancy and to ,subserve
also to that peculiarly marked steadi-
ness or directness of flight.
Made up, as it is. in three separate
parts, it is less liable to total and in
stant collapse in case Of puncture, and
it is even possible to secure wider
margin of safety by subdividing the in
teriors by thin membranous walls and
fitting them with little valves some
what like those now used on bicycle
tire, which would enable the balloon to
be filled, but which at the same time
would shut off automatically an in
jured compartment by virtue Of the
unimpaired force of the neighboring
good ones A happy, chance shot that
might damage one or even two of the
compartments would only cause the
balloon to sink slowly like an exhaust
ed bird, and would either enable the
aeronauts to prepare for. jump in
safety or permit the balloon to be
drawn beyond the reach of further at
tack before touching the water. These
balloons are built up in sections out

4 The especial advantages Of the bal
4 loon for naval work were discovered
SO recently as 1894. In that year the
Russian monitor Rusalka foundered
with all hands in the Gulf Of Finland.
An expedition, under aCOlonei Nicolas
d'Orloff, undertook to discover the 10.
cation Of the lost vessel by using a
captive balloon. for the purposes Of sub
marine observation and while he was
unable to find the craft. still the re-
suits OF his search were fruitful in val
l,ab1e information for future naval pur-
poses. The balloon, which was held
captive by a large naval transport fit
