After an abortive year at medical school following his father's calling, Lee Crandall went to work in 1908 following his own at the New York Zoological Park. He started as Assistant Curator of Birds, and writes today from his position as General Curator Emeritus. All that he says proves his assertion that ""a zoo doesn't Just happen."" His notebook is full of facts about all kinds of wild creatures, and how the zoo tried to make a safe (for onlookers as well as inhabitants) and happy. home for them. Longevity records, feeding habits, breeding prospects, safety requirements make up his story. The making of platypusary, Mrs. Martini's bringing up tiger cubs, preparing a vampire's dinner of blood, figuring the necessary breadth for a moat about the cats, and how to keep people from tangling with irascible animals like polar bears are a part of his animal tale. His own predilections are for giraffe and okapi, and ""the most beautiful antelope,"" the bongo. Zoophiles will be most appreciative.
