"Long before Scotland Yard or the FBI, Nature fingerprinted her numerous family," writes Ellsworth Jaeger in his remarkable book about a little-known field. "Tracks may take us back to the Earth's beginnings or give us a complete autobiography of a living animal from day to day. "Charmingly illustrated throughout, Tracks and Trailcraft presents a wealth of lore. In his crisp, direct style, Jaeger tells how to read nature's signs written in mud, brush, and even water and sky. It's packed with projects for both adults and children, nature lovers and amateur archaeologists - whether they want to follow the trail of a dinosaur that lumbered through the desert eons ago or the opossum that scurried through the backyard last night. Tracks and Trailcraft provides the tools of identification, turning anyone into a "nature detective. " This is a perfect book for the naturalist, the hunter, the weekend tracker, the nature guide, or camp counselor. (6 X 9, 392 pages, illustrations)
