"A bill has been introduced into the Mas
sachusetts Legislature to incorporate a
Pneumatic Express Company. The COM
pany proposes TO establish q line between
Boston and Roxbury: 6f 9at 5EHf 1sit 4
The method known as the Pneumatic
Dispatch consists of railroad track en-
closed in a tube the cars being driven by
atmosp pheric pressure; the car being, in eff
feet, piston, moving within the tube.
The velocity of the car is in proportionito
the degree of atmospheric pressure. which
is produced by means OF q ian or blower
operated by a stationary steam enginel All
that is required in operating the Pneumatic
Dispatch is little more than a tube, q car,
and revolving FAM The ponderous loco
motive is dispensed with. ,58i 8i5azs9e-o3 /
. 1t has been in practical operation in Lon
don for the last six years, where its capa-I
bilities for useful service have been tested,
and the economical advantages of it over
the present railway system has been con-.
cluSivelY shown. Cars have been driven
within tubes atsthe rate of mile Animate,
and it is believed that under theimpfoved
system of sending the cars a speedsof one
hundred miles per hour may be safely re-
allied. In cities, the tubes will be laid
principally under ground, butJin the coun-
try they will be wholly or partly buriedin
the earth, as rs most convenient. Hi lsCi
snThe advantages of this system are appa-
rent tolevery one. Thesroa6ls are less ex-
pensive and less 1iableltO accident. During
the whole six years. use OF the Pneumatic
system in London, we helieye not a single
accident to passengers or eInployessInas
been recorded. The track is so made that
it's external form in cross sections con-
forms to that aot the tube, although it,doeS
not fit it closely, an intervening space OF an
inch or so being lett all around.s10u liisa
3 Some light India rubber flanges or rings
are applied at each end of the truck; but
even these do not actually fit the inner sur
face of the tubes slight windage being
left around the whole truck. There is no
friction, therefore, beyond, that of 1.-The
wheels. The air is exhausted from one end
of the tube, by means of an exhausting
apparatus, and the car is .impellhda by at
mospheric pressure. The Pneumatic Dis
patch was originally conceived as a method
of carrying letters or dispatches only, but
the system has been so perfected that ma
terials ofnwhatever kind, and passengers.
can be transported with ease and safety
PlansIhave been proposed by which the
Pneumatic Dispatch system can be applied
to the city postal service, the,ears running
in tubes under the street lamp posts on
which letter boxes are placed, and so ar
ranged that while passing by they receive
the letters deposited in the boxes. Should
similar system be adopted, itwould great
Bly facilitate the collection zofu letters. 10
company has yet been chartered in this
country for the construction of sPneu-
matte Dispatch Road, and the one which it
lis proposed to construct between Boston
and Roxbury will probably be the first of
the kind on this side of the Atlantic. Should
the experiment prove successful, the line
will doubtless be extended, and numerous
others established within a! few years.
