Year: 1876

Alter q careful examination OF the
grounds the Centennial managers
have decided upon thirteen places of
entrance and exit, selecting these by
reason of their proximity to main
roads and to points nearest to which
railroad lines, the passenger cars and
the steamboats, will set down their
passengers.


The entrances will nearly all have
four gates-one for visitors proper to
the Exhibition, that is, those who
pay to go in; another bearing COM
plimentary tickets, third for exhib-
itors, representatives of the press,
and employees, In fact for all not be-
longing to the two classes just named
and another for wagons. At these
points of entrance, SO called, will also
be placed the exits. Based upon 3
careful calculation of the traffic over
each of the roads surrounding the
Exhibition grounds and leading to
the entrance points selected, have
been placed from one to thirty-three
gates or turning stiles. OF these
altogether there will be LOG. The
exits, in their vicinity, will be forty
two. Each turn-stile will be under
the control of keeper, who will sit
or stand behind short counter and
receive from each visitor the admis-
sion fee-a fifty cent note-before
the visitor passes the arm of the stile
which will, by mechanical contriv-
ance, be operated by the keepers
foot. As the stile turns for each en-
trance it registers itself as well at the
gate as electrically at the manager S
Office, with which each has electrical
connection.


The money, when received by the
gate-keeper, is deposited in box
placed under the counter, and which
also by a mechanical contrivance,
locks itself as it is pulled from the
position which it occupies when in
use. Its opening can only be effected
by the bank officers.


Between the two counters and en-
frances will stand an officer, who
will watch both lines as they enter

from the line, and pass him down
this passage out beyond the fence.


The exits are of ingenious con.
trivance, and while permitting freely
the departure of persons from the
grounds through turnstiles of rather
different construction than those de-
scribed above, absolutely prevent re-

of the gate post.


At the other side, opposite the

with this, and also on line with the
end of the fender opposite the gate
post, rises another post on which q
turnstile revolves, the four arms o.
which, repeated, rise as high as the
top of the lateral bars, between which
they pass each quarter revolution.
This latter works with n ratchet and

1t will be seen from this that when
visitor desires to leave the ground
he has to place himself into trian-
gle formed by two of the turnstile
arms and the tender. AS he moves
forward and outward, the turnstile
moves with him until he finds him.
self at the gate. He cannot change
his mind and get back, this being pre-
vented by the outward movement
controlled by the ratchet, nor can he
come in again without the payment
of another fifty-cent note, this being
prevented by the fixed lateral bars.


The designs of all the entrances
will be very neat and tasteful. The
