William J. Long was an American nature writer and minister best known for books that present woodland animals as subjects of sustained attention and curiosity. Works such as Secrets of the Woods, Ways of Wood Folk, and Wilderness Ways invite readers into the forests and lakes of northeastern North America. His storytelling emphasizes the individuality and resourcefulness of wild creatures.

Long served as a Congregational minister in Stamford, Connecticut, while spending extended periods in Maine and later Nova Scotia. He advocated quiet, patient observation as a way to encounter animal life. His accessible accounts reached a broad audience, including school readers, and illustrations helped bring the settings and animals of his books into focus.

His claims also became a prominent part of the controversy over so-called nature fakers, with critics including John Burroughs and Theodore Roosevelt questioning the accuracy of particular accounts. That dispute remains important when assessing his work. His books are best approached as influential examples of literary nature writing whose observations and interpretations require evaluation. They preserve an enthusiasm for close encounters with wildlife while raising lasting questions about where description ends and imaginative storytelling begins.
