Soil and Water Quality: An Agenda for Agriculture from the University of Iowa. He has been actively involved in research of agricultural and nonpoint source pollution, soil genesis, hydrogeology, and groundwater quality. He directs a variety of environmental programs related to agriculture including the Big Spring Basin Demonstration Project and the Model Farms Demonstration Project. NEIL D. HAMILTON is the Ellis and Nelle Levitt Distinguished Professor of Law, and the director of the Agricultural Law Center at Drake University Law School. He earned his B.S. from Iowa State University and his J.D. from the University of Iowa College of Law. He has been involved in research covering the legal aspects of agricultural finance, land tenure and land use, property rights and conservation and environmental law. His area of primary interest is agricultural law and agricultural law as it applies to agricultural and environmental policy and land use. WILLIAM E. LARSON received his Ph.D. in 1949 from Iowa State University. Now retired, he was the head of the Department of Soil Sciences at the University of Minnesota. During his career he was involved in research of soil structure and mechanics, water infiltration, nutrient interrelations in plants, crop response to soil moisture levels and soil temperature, tillage requirements of crops, utilization of sewage wastes on land, and effects of erosion on productivity and fertility.

About the Cartoonist J. N. ''DING" DARLING was an eminent political cartoonist whose career spanned the 1930s through the 1950s. Through cartoons, he brought the idea of conservation to the forefront of public awareness. He became chief of the organization that became the U.S. Fish and Wildlife Service, founded the National Wildlife Federation, and originated the Federal Duck Stamp Program, which has generated millions of dollars for wildlife refuges. After his death in 1962, the J. N. "Ding" Darling Foundation was created to continue his efforts in conservation education.
