Transcriber's Notes
Transcriber's Notes: Clear punctuation errors such as missing periods at the ends of sentences have been silently corrected. Hyphenation has not been standardized, for instance, Elizabeth-town, watch-maker, and over-all. The spelling of proper names has not been standardized, for instance, Blakslee and Blakeslee, Appalachicola and Apalachicola.
