This single volume of approximately 500 pages binds together several handwritten diaries by an unknown author about an extended trip in rural central Pennsylvania in 1840. The handwriting is almost illegible. It records the author's subjective experiences and impressions rather than geological information. Notes by an unknown researcher are available in the control folder; they indicate that there is no evidence of the author, but the title is "Gyrations of an Oyster through the Inane."
