Where to look for lost children

‘Little Lost Lambs’ Getting New Haven at Zoo

“Lost children will be taken to the Lion House” is the Washington Zoo's most quoted sign. Outraged parents of straying tots protested vigorously until they discovered zoo police headquarters was sandwiched above the lions. Now, at long last, the sign will be changed. Come winter, the Zoo is to have a new building, housing among other facilities, police headquarters and the most up-to-date comfort station. (Washington Post, June 26, 1955.)
