pollutants on the growth and survival of oysters and other marine organisms. In 1905, conducted a study on the effects of coal tar on oyster beds, and he served as a scientific consultant to the Rhode Island Commissioners of Shellfisheries in a pioneering 1910 water pollution case brought by Rhode Island oyster farmers against the Providence Gas Company. Prof. Field became a director of the Massachusetts Audubon Society, and in 1911, he was elected president of the National Association of Shellfisheries Commissioners. Following his work in Massachusetts in 1916, Field joined the Bureau of Biological Survey of the U.S. Department of Agriculture in the capacity of supervisor of the 74 national bird and mammal reservations in the United States. He served in that capacity until 6 December 1919 when he became a consultant to the Government of Brazil in the early 1920s on matters of environmental conservation. And in the early 1930s, he was a consulting biologist with the United States Department of Agriculture serving as the United States representative on international cooperation on water pollution control. As a result of complications due to an automobile accident in Paris during one of his trips to Europe as the U.S. Soil and Water representative to the League of Nations, Field died on 19 January 1938 in Washington, DC, and he was buried at Union Cemetery in Brockton, Massachusetts.
