Youngsters have been demanding a first book on automobiles that will answer some-if not all- of the questions on kinds of cars and what makes them run. The lively text and jaunty pictures by Jeanne Bendick tell a bit about every kind of car, -- family cars, trailers, jeeps, buses, fire engines, taxi cabs, and midget cars. Then comes the important part of the book-a simplified but at the same time surprisingly clear and detailed explanation of the parts you see and the parts you don't see and their functions. The reader learns how the car machinery is set into action, and a big double-page spread of the under-carriage shows each part of the mechanism in relation to the others. Even the end papers are full of factual interest, with pictures of the tools needed to keep a car in good working condition. Bound in sturdy cloth, this book will stand the wear and tear it is destined to have. The youngster who isn't ready to read it to himself, but who is interested in automobiles, and the beginning reader- say second and third grade- will be equally enthusiastic, whether the book is shared with a grown-up, or read with the eager intensity the young mechanic of today gives to subjects down his alley. Large type and lots of pictures help.
