Thoreau writes in his journal:
Saw at the Natural History Rooms a shell labelled Haliotis splendens, apparently same with mine from Ricketson’s [Daniel Ricketson] son, with holes and green reflections. To Purgatory in Sutton: by railroad to Wilkinsonville in the northeast corner of Sutton (thirty cents) and by buggy four of rive miles to Purgatory in the south or southeast part of the town, some twelve miles from Worcester . . .
