JENKS, John Whipple Potter, naturalist, born in West Boylston, Massachusetts, 1 May, 1819. He was graduated at Brown in 1838, was principal of Peirce academy from 1842 till 1871, professor of zoology in Boston horticultural society in 1858-'60, and has held the chair of agricultural zoology and the curatorship of the museum in Brown university since 1873. In the promotion of his profession he has been an extensive traveller in almost every country in Europe, and also since 1885 in every state and territory of the Union. The gathering of the extensive collections of Brown university is mainly due to his labors. He was the first naturalist to explore the everglades of Florida and the region around Lake Okechobee. Mr. Jenks's publications include bulletins on the "Food of Birds "in the annual reports of the Boston horticultural society (1859); "Hunting in Florida" (1874); and "Jenks and Steele's Zoology," a text book for high schools (1876, revised ed., 1887).
