Tops for the Ditmars' market, without the limitations imposed by the scientific slant. The story of the San Diego Zoo, told by the woman who runs it, and chockful of first rate anecdotal material about animals, about the machinery of running a zoo, securing the animals, planning the buildings, caring for the animals, etc. Stories of the people who come to the zoo, of what they might learn and don't, Zoo construction. Zoo hospital. The friendly gorillas. Very entertaining.
