Book excerpt: Florence Page Jaques and her husband, Francis Lee Jaques, who illustrates this classic with beautiful black-and-white nature drawings, experience an unusually thrilling winter vacation following the waterfowl migration. Beginning with a duck-hunting trip in Minnesota, Florence writes a lively and detailed account of their trip down the Mississippi flyway, through the White River bottom swamps in Arkansas, and around the Rainey Wildlife Sanctuary in the marshlands of Louisiana.
