Model Steam Tractor Made by Boy

Boys, and others who like to make models, may be interested in a small steam tractor I designed and built of scrap materials around the farm shop. I used only the ordinary tools on hand in such a place. The steam engine and tractor run smoothly, and the engine propels the tractor just like a large machine of this kind. The tractor is 28 in. long and 14 in. high, and the boiler holds 1¹⁄₄ gal. The bore of the cylinder is ⁷⁄₈ in. and its stroke 1³⁄₄ in. It was made from an old iron window weight. I use wood and coal to fire the boiler, and steam can be got up in a few minutes.—Albert H. Bennington, Park River, N. D.
