S. E. Forman,  Stories of Useful Inventions

“ In many cases it is easier to roll a thing than it is to drag it. This fact led to another step in the development of the carriage; it led from the cart without wheels to a cart with a wheel—a most important step in the history of inventions. The first wheeled cart was simply a log from each end of which projected an axle (Fig. 5) . The axle fitted in the holes of a frame upon which the body of the cart was placed and to which the horse or the ox was attached. As the cart moved along, wheel (log and axle) turned together. ”
