Book 2 — A Catapult
Reading edition
The catapult shown in the sketch is one I constructed some time ago and found to be amusing and very inexpensive. The catapult consists of a small piece of dowel or pine, whittled into the shape of a handle, a screweye, an elastic band and an arrow. It is surprising how a well-balanced arrow will fly into the sky until lost to sight when propelled through the eye of the screw with a medium-strong elastic. A number of forms of this simple gun were made, but the one shown is the simplest and most effective.—Contributed by C. A. Needham, New York, N. Y.
