This informative colorful book tells how the world's first bathysphere appeared. With this apparatus, scientists first saw the dark and mysterious depths of the ocean. At that time, there were no modern means of photography and filming. Underwater travelers on a telephone wire told about what they saw at depth, and the artist sketched the sea creatures they described. So people learned about the amazing life in the underwater world.
For elementary school age.
