The drum A is a piece of wood, 1 3/4 in. long and l 3/16 in. in diameter, supported on the end of a round stick, B, which can be made in one piece with the drum, if a wood lathe is at hand, but a piece cut from a curtain pole and a lead pencil inserted in a hole bored in the end will answer the purpose. Be sure to have the diameter of the drum 1 3/16 inches.
Ill: The Parts for Making the Revolving Drum tor Holding the Strip of Pictures
Provide a base piece, C, 1/2 in. thick and 2 in. square, and fasten a piece of cardboard having a slit E, as shown. The cardboard should be 2 in. wide and 2 1/2in. high, the slit being cut 1/2 in. in width, 1/4in. from the top and 3/4in. from the bottom. A hole is bored in the center of the block to admit the standard B easily.
The next step is to provide the picture and attach it to the drum. A picture of a boy pounding cobblestones is shown in the sketch, at F, which should be made on a strip of paper 4% in. long. This is glued or attached with rubber bands to the drum. The drawing can be enlarged in pen and ink, or can be reproduced as it is, if a hand camera is at hand, and a print used on the drum.
Ill: The Different Positions of the Picture will Appear in Action When Turning with the Drum
It is only necessary to put the parts together, grasp the base in one hand and turn the support B with the other, when, looking through the slot E, the boy is seen pounding the stones. Various pictures can be made and the strips changed. - Contributed by C. C. Fraser, Saginaw, Mich.
