achinery [216]

A good way to remove grease or oil from machinery before painting
is to brush slaked lime and water over the surface, leaving the
solution on over night. After washing, the iron is dried and the
paint will stick to it readily. In removing grease from wood,
common whitewash may be left on for a few hours and then washed
off with warm water, after which the paint will adhere
permanently.

** A Game Played on the Ice [216]

Two lines are drawn parallel on the ice from 50 to 100 ft. apart
and blocks of wood are placed every 6 ft. apart on these lines.
The player opening the game skates to the line and delivers, in
bowling form, a sliding block similar to the blocks that are
placed on the lines with the exception that it has a handle. The
blocks are about 6 in. wide by 6 in. high and 8 in. long. The
sliding blocks should be at least 1 ft. long and each provided
with a handle. The handle is attached by boring a hole near one
end in the middle of the block and driving in a wood pin. The hole
is bored slanting so as to incline the handle. Two of these blocks
are provided for the reason that when a player bowls one of the
opposing player's blocks over the line he is entitled to another
throw. The side wins that bowls over all of the opposing

players' blocks first. This will prove an interesting and
enjoyable pastime for skaters.

** Making Photo Silhouette Brass Plaques [217]

Secure a brass plate having a smooth surface the right size for
the photograph and cover it with a coat of paraffin. This is done
by heating the paraffin in a vessel hot enough to make the wax run
freely, then pouring the liquid over the entire surface of the
brass.

When the paraffin has cooled sufficiently the outlines of the
photograph must be drawn upon its surface. There are three ways of
doing this: First, the photograph can be traced on tissue paper
and then retraced on the paraffin surface. The exact outlines of
the photograph can be obtained this way without destroying the
print. Second, if you have several copies of the photograph, one
can be utilized by tracing direct to the surface of the paraffin.
In using either of the two methods described, carbon paper must be
placed on the paraffin before the tissue paper or photograph is
laid upon it. Third, cut out the outlines of the photograph and
lay it on the paraffin surface, then trace around the edges with
