"Time and Change" is a 1912 work on geology by American naturalist John Boroughs. Within it, Burroughs explores the beauty and science behind the history of the Earth in the masterful way for which he is famous. John Burroughs (1837 - 1921) was an American naturalist, essayist, and active member of the U.S. conservation movement. Burroughs' work was incredibly popular during his lifetime, and his legacy has lived on in the form of twelve U.S. Schools named after him, Burroughs Mountain, and the John Burroughs Association-which publicly recognizes well-written and illustrated natural history publications.
