The romance of transportation is not lost on Harvey Firestone, Jr., whose family has been identified with it since August 3, 1900, when his father founded the Firestone Tire & Rubber Company. He is both fascinated and familiar with his subject, as he ticks off man's progress across the face of the earth, on the seas and in the skies and into space. Man, who had been making the rounds on foot, thought of using the sledge in 7000 B.C., the ass in 3500 B.C., and ""the horse was a new development like the automobile or the jet plane:"" The first ""Suez Canal"" was dug in the twentieth century B.C. There were ships of sail, then steam (and canals to use them on), the iron horse (and rails), the Model T (and macadamized roads), and the aircraft from balloon to jet. Quickly moving from mode to mode, holding to a minimum of interesting and pertinent facts, Mr. Firestone keeps his book rolling, on the road, and his audience may extend beyond an invested readership.
