** Perfume-Making Outfit [363]

The real perfume from the flowers is not always contained in the
liquid purchased for perfume. The most expensive perfume can be
made at home for less than 10 cents an ounce. The outfit necessary
is a large bottle or glass jar with a smaller bottle to fit snugly
into the open mouth of the large one. Secure a small piece of very
fine sponge and wash it clean to thoroughly remove all grit and
sand.

[Illustration: Bottle with Flowers]

Saturate the sponge with pure olive oil, do not use strong oil,
and place it inside of the smaller bottle.

Fill the large bottle or jar with flowers, such as roses,
carnations, pansies, honeysuckles or any flower having a strong
and sweet odor. Place the small bottle containing the sponge
upside down in the large one, as shown in the illustration.

The bottle is now placed in the sun and kept there for a day and
then the flowers are removed and fresh ones put in. Change the
flowers each day as long as they bloom. Remove the sponge and
squeeze out the oil. For each drop of oil add 2 oz. of grain
alcohol. If stronger perfume is desired add only 1 oz. alcohol to
each drop of oil.

** Home-Made Duplicator for Box Cameras [363]

The projecting tube of the lens on a hand camera can be easily
fitted with a duplicator while the box camera with its lens set on
the inside and nothing but a hole in the box does not have such
advantages. A small piece of heavy cardboard can be made to
produce the same results on a box camera as a first-class
duplicator applied to a hand camera.

[Illustration: Duplicator Attached to a Camera]

The cardboard is cut triangular and attached to the front end of
the camera as shown in Fig. 1 with a pin about 1 in. above the
lens opening. A rubber band placed around the lower end of the
cardboard and camera holds the former at any position it is
placed. A slight pressure of the finger on the point A, Fig. 2,
will push the cardboard over and expose one-half of the plate and
the same pressure at B, Fig. 3, will reverse the operation and
expose the other one-half. Pins can be stuck in the end of the
camera on each side of the lens opening at the right place to stop
the cardboard for the exposure. With this device one can duplicate
the picture of a person on the same negative.
