In 100 small pages of large print, eleven brief chapters on (American) Bridges, Tunnels and Pipelines. Boats, Horses and Wagons, Bicycles, Railroads, Automobiles, Elevators and Other Lifts, Airplanes and Balloons, Rockets and Spaceships and ""the transportation problem."" Each is a cursory survey almost unillustrated (there are fifteen sketches in all) and often irrelevant. The near-absence of illustrations renders some of the discussions unintelligible; the presence of too little about too much makes the information meaningless. By land, see or air, there are better ways to go.
