airship a very certain endurance and
lengthens its voyages, enabling II TO cover
greater distance.
In short, II guarantees remaining anoat
for fifty hours, or as long as II has fuel.
These improvements begin TO put the
airship on a practical basis, like steamers.
DIR. Schuette says ne expects, within two
or three years, that much greater airships
will be carrying cargoes of thirteen and
fourteen tons, either in passengers or mu.
nitions of war. The greatest useful cargo
now carried is five tons.
The rapidity with which the size Of air.
ships is increasing is shown by the fact
that the present Schuette-Lanz is only
$50 feet long, while his new war airship
will be 100 feet longer.
This also applies to the Zeppelins, the
largest of which, the Hansa. Is 5a feet
in length and makes 1915 miles an hour,
while the new naval Zeppelin, TO be CON-
pleted In November, will have length OF
$50 feet, capable Of remaining in the air
forty-eight hours. while carrying cargo
of nine tons and making ffty-hye miles
an hour, to fulfil the government con.
tract. The naval Zeppelin will carry a
lifeboat and will be stationed at VII
helmshaven, on the North Sea.
The great naval Zeppelin now being
built for the German Admiralty will be
different from all former Zeppelins. II
will have nc navigating cars; engines and
crew will be carried inside the hull, along
with the gas chambers, giving the airship
a perfectly smooth under surface writes
T. R. MacMechen In Aircraft" which
of course, will make the craft much
swifter. as the outer hanging cars cause
some drag. II also increases the airships
aeroplane effect. In other words, II adds
both to the lift and speed OF the craft.
According to specifications, this ship
must make fifty-five miles an hour, but It
is confidently expected that 1t will make
sixty. II will be recalled that, according
to specifications, War Zeppelins | and II
were expected to make thirty-eight miles
an hour. but developed forty-seyen and
a quarter, so It is not too speculative 10
expect a speed of sixty miles from the
new naval Zeppelin.
The experiences gained from the Vik'
torla Luise in her series OF trips over the
North Sea and the Baltic Sea have sup
piled the Zeppelin engineers with data
that will enable them to increase the
lifting capacity on the naval airshlp over
water and furnish the knowledge heees'
sarv 10 improve its steering device 10
take advantage Of great winds.
The tests of the Victoria Luise and the
Hansa over the Baltic Sea have proved
these important points:
Ffrst-That the airship can travel per-
fectly In complete darkness. acquiring
knowledge of its locality at all times BY
atmospheric localization. That Is 10 sa!
it holds it's position in the wind OF KNOWN
speed and direction at liked neigh.
above the water, finds its LATITUDE ana
longitude by the stars and follows !"
course by the compass.
Second-It has demonstrated that
can descend and scoop the water from
the sea, therefore increasing It's ~e'sn'
at any time that IL is expedient TO do so
Third-It has demonstrated that IL can
take gas and fuel from steamship on
the ocean by lowering gas mains or cables
Fourth-It has been learned that tns
ship flies much steadier In higher "ihu'
over water than In lower winds over lanu'
FYfth-It has been ascertaired that h'
ras is much less affected by flying Owe
water than flying over land. which
perfectly natural when 1t Is rememoe'sa
that the heat thrown of by the earlh
much greater than that from the wafer
sixth-All these demonstrations nA''

turned theory into fact-and are plo'ns
that the ocean is the most suitaO'e w.
