For Machine :

Washington, ID. c., March 12.-lt Is
possible for aeroplahes OF. the pres.
ent patterns and strength to cross
the Atlantic ocean. BY keeping to
high attitudes, the feast is likely tC
prove less difficult than it would ap
pear. This is the opinion Of DR.. Al
exander Bell, set forth in his lecture
on aerial Flight before the lad.
les night meeting of the Federal
Schoolmen's club.
1T is Obvious" said Dr.. Bell to the
! guests of DR.. Arthur r. Ramsay, pril.
cipal of the seminary, and Mrs: Ram
say, that to make the journey Of
1000 miles in a flying machine THAI
will attain the speed of 100 miles al
hour and can hold it for twenty con.
secutive hours is required. We al
ready have machines of that speed
So it is simply a question of the en-
| CINE holding out.
although at a great altitude the
density of the air is %lessened, with 9
consequent higher rate OF revolution
OF the propeller, the force exercised
by the propeller at this higher rate
would be as great as that near the
earth. Moreover, the very lack O:
density Of the atmosphere would offei
less resistance to the air craft, witt
a consequent increase of speed over
that attained at a lower level.
More Height, More Speed.
"The great essential is a system OF
| changing gears n~ecessitated by the
| higher rate Of revolution Of the pro
| peller. In other words, the higher the
| machine flies the greater the velocity
to be attained.
"The question of sufficient oxygen
for the driver is solved by the ire
nendous speed Itself. fol. the all
striking the face would be condensed
As for the cold at such a height the
| exhaust of Re machine furnishes q
| source of heat easily applicable t.
keep the aviator properly warm.
"When it is realized that an aero,
! plane with an ordinary speed of fift..
miles an hour attains at a proper
height a speed of, say, 100 miles al
hour. think. we may safely say tina.
we will. see airships crossing the AT
lantic at a height Of two miles above
he earth, driven by warm and com
Portable aeronauts."
ForeteIis New Motive Power.
After the lecture DR.. Bell gave a:
an opinion that the time woulf
come when microscopic portions o.
high explosives would furnish mo
tive power for air craft, just as
drops of gasoline do at present. lr
addition TO his prophecies, the sneak
er traced in detail the history of aero
nautics from neurological times. with
the various theories that flourishe6
and fell. until Pref. Langley and the
Wright brothers finally demonstrated
the entire superiority of heavier
than air-machines.
He told of the plans for such a ma
chine, drawn by an inventor as lone
ago as 1912, characterizing them as
admirable and correct in principe
and only precluded from resulting n
a parctical craft by the lack OF sufh,

"LOoK OUT FOR THE CARS"
Chicago, ILL.,, March IA plan for
uniformity in railroad crossing signs
throughout the country is one of the
principal matter. to be considered at
the fifteenth annual convention of the
American Railway Engineering Asso'
citation, which began in this city today
with an attendance representing the
leading railroads. of the United
| States and Canada. Advocates of, the
plan for uniform crossing signs con
tend that it will result in greater
safety and economy.
