The history of man may almost be said to be a history of communication. In this elaborately illustrated text, the complex and varied means by which man, for 2500 years, has fought the isolation of non-communication, are traced. Embracing history, archaeology, sociology, science, and art, every intellectual means at his disposal has had as its seed and fruit the impulse toward a more complete intercourse. A full and animated account, Lancelot Hogben's text goes far to show that the world of communication is indeed a world rich in wonder. Within the grasp of junior high school students, there is much here to appeal to more advanced readers.
