Washington: Home of the Nation's Great 725 Staff Photographer B. Anthony Stewart Fifteen Feet of Legs and Neck Inspect the People in National Zoological Park Yearly some 2,500,000 visit the National Zoo's wooded home in Rock Creek valley. There about 2,500 specimens live in comfort. Penguins enjoy refrigerated rooms. In winter this $6,000 giraffe, born wild in the sultry Sudan, gets steam heat. A National Geographic Society-Smithsonian Institution expedition brought him to Washington 10 years ago. Giraffes' fragile bones worry keepers. Mangers are perched at a neck-saving 12 feet. Dr. William M. Mann, director of the Zoo, has never heard a giraffe; others have reported a once-in-a-lifetime "moo" of anguish.
