them.
As received from the factory. the mega
tive flm IS In lengths of .5 feet
FILM Is PERFORATED
These sirius are taken into a dark room.
Cured and then placed in a perforating
machine that makes four small holes on
each edge to every inch.
The perforator Is worked by electricity
and is self feeling.
Its mechanism is so absolutely perfect that
a variance of a hairs breadth is not made.
After being perforated the film is reWound
upon reels and loaded into cartridges FOR
use in the camera
The camera looks like an extra large c.
gar box and weighs about fifteen pounds
II is stood upon end. with the reel of film
on top. 50 that il may be fed downward by
4 crank. !
on the front side Of the box. near the top.
is q hole through which the lens Receives
light. !
A rapidly revolving shutter alternately /!
closes and exposes this hole. giving The
t,lIn I picture at each revolution
The shutter works 50 rapidly that it can !
not he seen when in operation
The film is fed downward into the bottom
of the camera where i Is automatically
wound up on a reel as fast as the pictures
are taken.
There are sixteen pictures on each foot
of film, or 5000 10 the I.or feet.
Thus it will require 5000 distinct photo
graphs to show the world what the Louisi-
ana Purchase Exposition looks like now.
After the film leaves the camera. il is de-
vel0psd in a dark room. where more WON
Gers are worked !

onto a big dcLu. /
The developing solution Is fed into the
trough and the drum dropped into il.
This is done quickly, SO that one part
will be developed no more and no less than
another.
II ten feet of the film were overexposed
and an equal humber of feet UndereS-
posed. it .an be imagined what effec, it
would have on the completed picture. when
shown on a curtain.
Now the cylinder is raised. revolving as

made of wood and covered with wax. and I,
the washing process Is completed.
Finally. the film Is taken from this reel
and run onto rapidly revolving Crying reels
in another room
D~JST-PROOF D~RYING-ROOM.
The drying-room is another wonder.
II is absolutely du>t-proof, because the
smallest speCkS Of dust on the films would
spoil IL.
The flickerinG OF the pictures now and
then as seen in the theaters is caused by
