Susan and Theodore Crane surprised their brother-in-law Samuel L. Clemens with this study in 1874. It was placed about 100 yards from the main house at Quarry Farm on a knoll overlooking the Chemung River Valley. In this octagonal building, Mark Twain wrote major portions of The Adventures of Tom Sawyer, Adventures of Huckleberry Finn, Life on the Mississippi, A Connecticut Yankee in King Arthur’s Court, The Prince and the Pauper, A Tramp Abroad, and many short pieces.
