Bolen discusses the life and activities of political cartoonist and conservationist Jay N. â€œDingâ€ Darling. Although his cartoons were critical of the New Deal, President Roosevelt appointed him head of the Bureau of Biological Survey, the forerunner of the U.S. Fish and Wildlife Service. It was Darling's promotion in 1934 of the Migratory Bird Hunting Stamp that secured his legacy. The first stamp sold for $1 and raised $635,000 for conservation efforts. Since then this stamp program has generated over $700 million for conservation.
