Here is -- between the covers of one book -- basic industrial material of social import that should be a ""must book"" for every thoughtful boy and girl of high school age (and for most adults). Through a sound basic knowledge of the development and ramifications of the industries which provide us with our needs, we should be able to insist on higher standards, and to know what we want and why. This tells the story back of milk, canned goods, farm products, textiles, fabrics, electric lighting fixtures, automobiles and many other things, related and involved. Interestingly told -- a challenge to the buyer. Good format.
