Fig. 4.—The lion and his cage.
Draw a lion and a cage, as in [Fig. 4]. If you place a visiting card upon the line A B, and put your face so near that the right eye looks upon the lion whilst the left can see only the cage, you will observe the lion walking into his cage as naturally as if he were at the Zoo!
A rather amusing experiment, and one which will afford immense pleasure to the juvenile members of your party, is as follows:—
Cut a circular disc of stout cardboard 12″ in diameter. In the center make a hole to allow the disc to revolve easily, but not loosely, upon a wooden penholder, which should be fixed at right angles to a wooden stick ([Fig. 5]).
Fig. 5.—Disc of cardboard kept in place with penholder.
Fig. 6.—Showing box in correct position.
Upon the center of the disc fasten a cylindrical cardboard box (A, [Fig. 6]), with the penholder passing right through it. This box should be roughly 3″ high and 2″ in diameter.
