A foul ball is indicated by Fig. 2, the knife resting on its back.
The small blade sticking in the board which holds the handle in an
upright position, as shown in Fig. 3, calls for a home run. Both
blades sticking in the board (Fig. 4), a three-base hit. A
two-base hit is made when the large blade sticks in the board,
Fig. 5. A one-base hit is secured when the large blade and the end
of the handle touch the board as in Fig. 6. The knife falling on
its side (Fig. 7) calls for one out. Each person plays until three
outs have been made, then the other plays, and so on for nine
innings.

** How to Remove Paper Stuck to a Negative [250]
When making photographic prints from a negative, sometimes a drop
of moisture will cause the print to stick to the gelatine film on
the glass. Remove as much of the paper as can be readily torn off
and soak the negative in a fresh hypo bath of 3 or 4 oz. hypo to 1
pt. of water for an hour or two. Then a little gentle rubbing with
the finger-not the finger nail will remove anything adhering to
the film. It may be found that the negative is not colored.
