DC Eausset's Mammoth Airship.

Jules Verne's 'sRolur, the Con.
qucror," may yet live in flesh. and
blood. Atanv rate, Arthur de Baus'
set. Il compatriot Of the famous omar
Ger, produced charts, formulas, and 4
discourse before the Chicago Electric
Club recently.
Arthur de Bausset is a physician, 6
man of science and an enthusiast, and
Ire would have started for the North
Pole last june in an air-ship with zoe
suinnaer tourists if S150, 900 had been
forthcoming and no screw turned out
to be loose.
He hopes yet to raise the money,
! show that his screws will hold tight
and make the trip. Moreover, on his
return he expects to carry tho mails
of this country and establish 4 new
system of transportation in genral.
'.NaE;gation of the air by balloons
inflated with gas" said DR.. dc Bausset
in his address, sis a failure. Harve
Mango, servant of the French Acade-
INV, and his companion De l'Hostc.
lost their lives five months ago by the
contraction of their balloon in q cold
current.
II introduce a c principle. I dis
card the yielding balloon. l do not
use gas at all, construct a cylinder
wholly of steel. I make it rise by ex-
Aausling it of air and producing &

The "acro-plane" is to be no small
affair. according to DR.. de Bausspt's
plans il is a cigar shaped ship, Col feet
long by 144 feet in diameter-as big as
thc Exposition Building.
