Iaroused that flood of feeling that surged
through that train. 1t was sympathy
with sentiment far older than loyalty
older than the kings to whom loyalty is
due-which was stirring every heart; it
was sympathy with a mothers love.-J. 5.

A New Air Ship.
A BALLOON WHICH CAN BE STEERED-A
TRIAL TRIP SOON TO BE MADE FROM
BALTIMORE.
Mr. F. w. Schroeder, an nronaut of
Baltimore, thinks that he has solved the
vexed problem which brought " Darius
Green and his Flying Machine " to grief.
His new patent air ship is thus described
by correspondents The skeleton Of the
ship is made of double o wire. braced
lengthwise by single o wire. The ship
itself is eighty-fve feet long. nine
feet hi igh, and eight feet wide, ant. its
shape resembles II long steamship hull,
with the exception that the fore and aft
objections extend about seven feet
from the body of the ship. The iron
shafts run lengthwise. the pushing propel-
ler being attached to one end, and the
pulling propeller to the other, in order
that they can be worked to the best ad-
vantage, and to allow the ship TO turn
around on its own pivot in the air. Cr-
derneath are two rudderS, one fore and
one aft. for steering purposes. On making
the ascent. the pulling propeller will be
put in motion, assisted by the pushing
propeller and the rudders, and thus the
inventor confidently expects to be able
to 90 whithersover he will. The ship is
attached to the balloon by 1897 ropes. sit
uated at equal distances apart in order to
preserve ms exact a balance as possible.
The capacity of the balloon is 26J, $40 Gu
bic feet. Hydrogen gas will be used, and
this substance is SO light that it is calcula-
ted that one cubic foot will have lifting
power Of one and three quarter ounces,
thus making the lifting power Of the ba-
loon about 10000 pounds. or nearly fifteen
tons. 1t is not probable that the balloon
will be inflated to its full capacity, mas
much rs the extreme rarefaction Of the air
ut great attitudes tends to withdraw the
outside pressure from the balloon. and
the hydrogen inside, thus relieved of out
ward pressure, will expand the more
readily and perhaps burst the balloon.
But estimating the capacity at an amount
less than that given, the balloon will east
ly have lifting power of ten tons. while
the weight of the apparatus, the gas, bal
loon. netting, ship and machinery is but
4SOO pounds, or two and two-tifths tons.
SHIP.
The balloon is fastened to the ship in such
a manner that it cannot sway to and fro.
50 it is impossible for the balloon to get
out of perpendicular position. The
ship has two masts. fore and aft. which
reach up to the equator of the balloon.
On the top Of each mast u large wire cap
is fastened to the netting perpendicularly,
and the balloon itself is fastened to the
netting all around its equator. In case of
an explosion the lower part of the balloon
ascends. falls into the netting and half of
the ba loon forms large parachute, the bal
loon descends for 8 short distance with
great rapdty, when the air pressc. up un-
derneath, the parachute spreads out, and
the descent is made more gradually. The
steering apparatus and propeller are set in
motion, the rotary movement commences,
and the balloon goes down in circle like
an eagle spreading its wings. The bal
loon is made Of cambric muslin. of which
1900 yards have been used in its manu-
facture. and the length of rope used is
nearly twenty-one miles The pulling
and pushing propellcrs are worked bv
cranks, four men at each crank, and work
in the lower currents about three hundred
and fifty revolutions 4 minute, increasing
the number Of revolutions with the increase
in height. Aided by the pulling and
pushing power, the inventor claims that he
will be capable Of making the ship stand
still in the air over anv given point
Practical use will be made of this advan-
tage by taking photographer along, for
the purpose of securing Photographic
views OF certain sections of the country
From Il certain height in the air he SAYS
he can see the bottom of any body of WA
ter, no mater how deep. The photo
graphic views which he proposes to have
taken will be chiefly useful to the Topo-
graphical Corps
WHAT TIE INVENTOR HOPES TO DISCOV-
Mr.. SchrG.lc Ter says that his experience
has proven to him that the higher atmos-
pheres approaching the North Pole. where
the lower currents increase in cod, the
upper currents increase in warmth, and
he is therefore confident that he is cap,-
BILE of sailing over this region and finding
that for which millions have been spent
and many valuable lives lost-a passage
to the open Polar Sea. The first ascent
will be made in about two weeks. and
will be quite An event in Baltimore. Be
sides his eight assistants At the propellers.
Mr.. Schr1 ler has invited the representa-
tives of the press to 60 with him. The
contemplated route is from Baltimore to
New York. stopping over at Wilmington
and Philadelphia for the purpose of tax
ing photographs of those cities. 1t has
been estimated, from the calculations and
experiments. that an average speed of
sixty or seventy miles an hour can be kept
up in \ moderate current of air. In
stronger currents the speed will be less,
although greater than that made on our
