Art il being made to raise funds by popu-
Hrd9llar subscriptions for tho building OF
Immense air ship 1t Is hoped to secure
IL. 1860, and the money IS asked lot VIII the
grstanding that the succes OF the lnVeu-
,M il not guaranteed, and chat if it fails
fns subscribers will lose their money. The
sr.. IS placed so high, in part. because 1t
,rIH be necessary to make special machln-
cry. If another ship Of the same size were
tnbe built it is believed that Its cost would
not exceed $4,000 Subscriptions are
g.w being solicited for stock
SHARES Il 81 each, up to the
amount Of $250, 900, and few have come
IL already According to the plans OF the
uQmoters half of the stock Is to be held by
Dr. Dc Pausset, and the other half is to be
hed proportionally by the takers Of this
popular subscription. With the indOrse-
:. t1l, l,ee horCrna SnOpra6 for the
principles on WHICH the air ship is built, it
i believed that it will surely succeed, aud
thai for exhibition purposes it will prove
paying investment 10 say nothing about
It's practical use for the transportation of
passengers aud freight.
The scheme of this monster of the air (for
the length of the Ben Franklin will be
greater than that of the Great EASTERN is
such as might well come from the country
Of Jules Verne, of Liberty Enlightening the
World, and Of the EIffel tower 1t is im-
mense in its design and bold in its attempt,
for no model has been built to prove the
practicability of the theory, for the reason,
as the inventor tells me- that in model the
proportions are so small that there cannot
be secured the ratio of vacuum TO the
weight Of the ship that is necessary
to make the oontrivance float Therefore,
tull-Szed ship must be constructed for
ialr trial OF the experiment. The new
feature Of this latest attempt at aerial nav
igatlon Is that, instead of using gas and q
flexible reservoir, the inventor indeavors to
procure vacuum and to keep all the parts
q bis Invention perfectly rigid 1t is pro-
posed to make the she'll of this olgar-shaped
balloon OF steel, with its interior 50 sllD-
ported by braces that it will withstand any
atmospheric pressure that can possibly be
Drought upon IL, The pressure Of the at
hoSphere at the sea level, when the temper
azure is at the zero point OF the centigrade
.eeiinometer and the mercury in tine tube
u 'is barometer stands at thirty inches, is
tlne lets than fifteen pounds to the square
Ilcn Ihe thickness of the shell of this
vacuum Is to be one fortv-fourth of an
slca' by the use OF the braces inside at
frequent intervals, it is SAID that a pressure
VI tprty three pounds to the square inch
san W resisted thus there has been secured
npie 1han twice the resistance that is
needed The inventor says that this nsrt
