(Minneapolis), (Federal Cartridge Corporation), (1952). Kaupanger was a "self-styled conservation watchdog for more than 40 years," according to his obituary, and secretary of the Minnesota Emergency Conservation Committee. This primer on conservation, covering such topics as soil, water, flora, fauna, education, and administration, was published by his employer, the Federal Cartridge Corporation, and carries a foreword by the company's founder. Federal is still in business, selling guns and ammunition, and touts on its website "a century of commitment to conservation." Inscribed by Kaupanger in 1957. Slight shelf wear; near fine, without dust jacket, likely as issued. [#036534] $300
