The Boy’s Own Book of Great Inventions
By F. L. DARROW
With many illustrations.
Every boy—and many a girl, too—likes to make things, and it is out of this certain interest which youth has in invention that this book has grown. Its appeal is primarily to the inventive faculty latent in every youngster. Not only does Mr. Darrow describe the great inventions of man, but he applies the principles underlying them to simple apparatus which the boy can construct for himself. The aëroplane, the balloon, the various kinds of engines, the telephone, the telegraph, the submarine, the telescope—all these and many more come in for consideration, followed in each case with simple experiments which the reader can make for himself, and in many cases with explicit directions for the construction of an adaptation of the machine or instrument.
