This boat is sawed out according to the drawing, and notches cut on
the arms at the stern as a place for the rubber band which serves both
as axle and motive power. The paddles are sawed out to fit together to
form a stern wheel with four paddles.
The elastic is made in a double loop of four thicknesses, one of which
is placed in each of the four angles of the paddle. By twisting the
elastic band, power is stored up sufficient for the boat to attain a
fair rate of speed. A spool serves as smoke-stack.
Paint the boat white and smoke-stack red.
