difficulty doea not I'm reality exist. In the first place,
care will be taken to pack the load In the spheres

In the next place. centrifugal action and rotary motion
will suffice to keep everything in its place, even II not
tightly packed except at the moment OF departure and
OF arrival. 1t is to prevent shaking at these two
transitional points that the proper packing OF articles
liable to injury will be requisite. When the spheres
once in motion, nothing inside will move The effect OF
rotary and centrifugal action s illustrated in the OF

equal to a speed OF feet a second five miles

EQUAL LOADING.

will state that: 1. The weight Of the sphere w with
light articles cOunerbaance any slight variation in tho
load With heavy articles, the weight Of the load and
the sphere combined will in like manner counterbahnce
slight Irregularities, and none other need exist. B.

RATE OF SPEED.
The velocity with which the spheres will move may be
eSimaed by that Of the locomotive and the flight of
birds. A locomotive running alone and on good track
will attain speed Of 100 miles hour. II this rate OF
speed is possible with q heavy vehicle weighing over
GOOO0 pounds, and running 16 wheelsthOse Of the
tender included-and on two separate rails, that are
never laid exactly even and smooth, we may safely cal
cuate for the spheres moving single track smooth
and even and rolling surface much less in breadth
than that Of single wheel, speed at least double
200 an hour. The ght of brdsthe second ndicatOnis

confident at least the OF these rates. which gives
very nearly the speed above stated * The advantage
which the bird possesses Of moving through friction
less medium is possessed by the spheres, and to the
fullest extent for while rolling frctionless their
peripheries, they move with the current OF air. In
addition tho gravity Of the spheres supported on their
track, is for them-an advantage which the
bird does not possess for 10 must sustain It's weight in
the air by the action Of its wings Taking guido
these various data estimate for the spheres moving
at their low rate of speed 100 miles hour and at their
high rate, 200 miles, Another datum which is entitled

zones, that their products may be recprocaly

COST OF CONSTRUCTION.
Any intelligent carpenter can, with proper facts cacu

think sufficient: For tube of the medium size, say
six feet in diameter, plank, two inches thick
tongued and grooved will be abundantly strong. Thick
sheet iron the hoops inside, would also The
beams which the tubes rest will DE by IL inches
The posts supporting the tubes will he placed 20 feet
apart, with upright between them; the timber will
be six inches square The posts will rest on two stone
piers reaching below frost. The hoops will bo four feet
apart with clamps TO them up The ends Of the
tubes will be tongued and grooyed, and slip into each
other hoop will the joint If proper mechanical
facilities provided to construct the tubes they
be put together rapidly and cheapy The metallic plate
