TT is n poor and inadequate thing 10
say that all the transit systems OF t'le
world must inevitably be revolution
lied by the Brennan Mono Hallway. the
working of which Louis Brennan, c. b.
bears his name. gave before the Royai
society last night This is undoubtedly
the most wonderful invention of the day,
and the possibilities of It's future are al
most beyond comprehension Travelling
now at one mile per minute is considered
about the limit, nut when the brennan
system is applied the enormous rate OF
300 miles an hour is attainable.

perfect control OF the inventor. Vehicle
Just large enough to carry a man scaling

like a miniature motor car devoid of the
customary wheels. Not. of course. that

set In line along the length OF the center
OF the car. were beneath the vehicle and
almost invisible.
Thus. to the Amusement OF every one.
as the machine ran back and forth. the
car achieved the task of balancing Itself
on the wire great deal more steadily
than ever BlondIn balanced himself on his
rope.
Done on Spinning-Top Principle.
How IT is done, and what IS the explana-
ton or these extraordinary phenomena?
The essence and principle OF Louis Bren-
mans invention. what Is the claim of his
patents now granted all over the world.
is the ;mparting OF stability to unstable
vehicles by means OF horoscopes In the
mind OF the average person the word
gyroscope Is associated with a circular
disk of metal spinning within n movable
ring. which was the toy OF his childhood.
TO even the most scientific the gyroscope
has always remained as little more than
toy Mr. Brennan In his laboratory
takes that childs top and places the axis
of the ring on n fork like the legs of a
songs, and To- the tongs stands upright,
as the spinning top rests upon them; ana
then strange movements begin to manifest
themselves In the surrounding ring.
The combined structure leans over us
The ring moves in one direction, and the
movement OF the ring, Mr.. Brennan tells
you, Is the procession OF the gyrostat.
One feels inclined. as it leans over. to
move the ring against the direction In
which the top is falling. but the inventor
gently touches the ring with the point
Of his pencil, not, as one would think, TO
bring il upright, but rather in the direc-
ton that would accelerate downfall. and
rs he does SO, the startling thing hap
pens that the whole combination rights
Itself This Is the essence Nand brains OF
Mr.. Brennan's invention, that by increas-
Ing the acceleration of the procession OF
the ryrostat. he establishes equilibrium.
In the simplest method covered by Mr..
Brennan's patent. he regulates this pre-
ression by an inverted pendulum. NO
outside control is necessary; the Brennan
invention imparts stability to vehicle
absolutely unstable.
Requires no Human Control.
It does not require the watchfulness
OF human control; It is mechanically auto
matte; the vehicle itself may be driven by
steam. electricity, petrol. or what you
like. In little compartment weighing In
his model only per cent. of the total
weight of the machine, and which in the
full-size vehicle now in course of con-
,struction will weigh only per cent. Is
contained the mechanism which imparts
stability to the whole.
In the model the horoscopes run at the
rate of about 1000 revolutions per minute
In the full-sized machine they run Mt the
rate of about 5000. The obvious objection
is-what would happen ii the horoscopes
stopped? What would happen II the whee
or axle OF locomotive broke or the boil
er burst?
AS against the fierce wear and tear o.

bearings and system OF fabrication, hi:
invention, which causes the working part:
to run on a constant film Of oil. and re
duces the friction to an intinitesimal min
imum. is Theoretically sealed in chamber

That the demonstration was not mere
" an experiment. but piece of actua
work. is clearly shown by the fact tina
Mr. Brennan has frequently placed hi:
laughter as passenger in the swift,
moving car. No more human test coult
be asked.
TO a mind gifted with Imagination, thu
possibilities of such an invention are Il
once obviously without limit. 1t Is, how
ever sufficiently staggering to deal Will
the bare probabilities of the concern.

And it is doubtful If the surface OF tn
world represents the only field of activit,
