The essay "In the October Moon" is included in his book Wild Life Near Home, published in 1901. John Burroughs said of the book "of all the nature books of recent years, I look upon Mr. Sharp's as the best." Excerpts from this book were collected in a small volume called A Watcher in the Woods, published in 1910 and intended for schoolchildren. My copy of the latter book has, stamped in light blue ink on its title page, the words "Prescribed for eighth grade reading in the 1910 syllabus of the New York State Dept. of Education".
Several people have owned the book before me. Written on its pages is the name of someone who called himself "Junior" in 1913, then seems to have decided to call himself "Jimmy" in 1914. These are written in indigo ink, in much better handwriting than mine, but a little awkwardly by the high standards of the time. There's also a (later?) name, written lightly in pencil, of a lady named Elizabeth. These are the things that change a book from a document into an artifact.
