failed TO get some of the old pIates thary
oughly clean A bearded gentleman in a
broad-brimmed hat came 10 have HE nio
ture taken and the resulting negative
showed him true to life, but In addition 70
his portrait there was a ghostIy outline of
woman in white with flowing veil and
orange blossoms. The stranger was shown
the negative and was tremendously i'm
pressed with 1t. He thought that he had
been honored by some spirit from the be-
yond sitting with him for his picture. At
last the photographers decided to embark
in the held OF spirit photography, which
they did with wonderful success until the
secret OF their art was discovered There
are many methods of surreptltiously treat
Ing Photographic plates before exposure.
But even after they are exposed they may
be changed by the skiIlful use OF the re-
touching process, by interposlng a magic
lantern slide between the plate and the
light before development and by many
other methods.
But still other means may be used for
inducing the Photographic plate to declare
that which IL not true For instance. a
tiny picture may be taken on a transparent
film, much like the image on a moving
| picture film This small image in outline
| may be pasted on the lens with trans
| parent paste and thus reflected upon the
Photographic plate when the exposure for
the principal figure is made. BY systems
OF double exposure one may be made to
stand face to face with himself, cut off his
own head or do any Of innumerable tricks
that are possible only In the realm of the
| fourth dimension
The spirtuallstlc portrait painters and
| photographers manifest a genius worthy OF
a better cause. They use the secrets Of
chemistry, apply the principles OF acoustics
electricity psychology and OF every other
art that will serve to mystify the people
Even now they are looking toward wire
less telegraphy and telephony as an aid in
the practice OF their profession. They be-
lieve that IL instruments suited to their
needs can be produced the length to which
they can go in the production OF unex-
plainable things will be almost limitIess
