As Joseph Cornell's classic book reached its 20th anniversary, Cornell drew upon a wealth of experience in nature education to significantly revise and expand his book. New nature games - favorites from the field - and Cornell's typically insightful commentary makes the second edition of this classic even more valuable to nature lovers world-wide. The Sharing Nature movement that Cornell pioneered has now expanded to countries all over the globe. Recommended by Boy Scouts of America, American Camping Association, National Audubon Society and many others.
