The book starts out with a recap of primitive man's first struggles with a log sledge and proceeds to the cars of the future without missing much that went between. It is profusely illustrated in rich colors and the text is international in scope. Of particular value are the big cross-sections and labeled diagrams of such diverse transportation concerns as Roman road beds, automobile assembly lines and the internal combustion engine. The first part of the book is given over to the discussion and illustration of every wacky and wonderful device by which man finally arrived at the horseless carriage. Roads, fuel (consumption and supply) tires (design and manufacture) as well as automobile accessories are here, too. The most space goes, of course, to accurately illustrated cars from the first Daimler forward. The book would be even better with an index and some small cartooned drawings are occasionally intrusive, but these are minor objections. The book will say ""Pick-me-up"" to boys of all ages.
