Reminiscences of Some Uncommon Characters I Have Chanced to Meet: featuring Artemus Ward; Dick Baker the quartz miner; Riley the journalist; then king of the Sandwich Islands; etc. "A reporter for the Bethlehem, Pennsylvania, Daily Times claimed that the lecture was made up almost entirely of humorous incidents from Innocents Abroad,..."
October 16 - Moravian Day School Hall, Bethlehem, Pennsylvania. "Uncommonplace Characters"
The East Pennsylvania RR runs to Allentown.
October 17 - Opera House, Allentown, Pennsylvania. "Uncommonplace Characters"
October 18 - Music Hall, Wilkes-Barre, Pennsylvania. "Uncommonplace Characters"
From Wilkes-Barre Twain would return to Allentown. From there to DC: East Pennsylvania RR from Allentown to Bethlehem; North Pennsylvania from Bethlehem to Philadelphia; Philadelphia and Reading RR through the town of Philadelphia; Philadelphia, Wilmington and Baltimore Railroad from Philadelphia to Baltimore; Northern Central RR from Baltimore to Washington D.C.
Twain abandoned this lecture after only three performances. To his wife he confided - "This lecture will never do. I hate it and won't keep it." In Washington - "He spent the weekend furiously writing a new lecture, confining himself to only one of the uncommon characters he had met, Artemus Ward."
October 23 - Lincoln Hall, Washington, D. C. - "Artemus Ward"
October 24 - Institute Hall, Wilmington, Delaware - "Artemus Ward"
October 25 - Odd Fellows Hall, Norristown, Pennsylvania - "Artemus Ward"
Mark Twain reportedly returned to Hartford on the 26th of October. Twain would then take the New Haven, Hartford and Springfield to Springfield; the Boston & Albany RR to Pittsfield; and the Housatonic to Great Barrington.
October 27 - Sumner Hall, Great Barrington, Massachusetts - "Artemus Ward"
After his Great Barrington lecture of Friday, 27 October, Clemens had a free weekend. Probably he spent it in Hartford, about sixty miles away, before keeping his engagements in Brattleboro, Vermont, and Milford, on 30 and 31 October, respectively. SLC to OLC, 31 Oct 1871, Milford, Mass. (UCCL 00668), n. 2.
October 30 - Brattleboro, Vermont - "Artemus Ward"
The route between Brattleboro and Milford is unknown. The 1870 kml files have an hypothetical line from Brattleboro to Athol, then the Vermont and Massachusetts line to Ayer; the Worcester and Nashua to near Pingryville; then the Fitchburg to West Concord. The kml files display the Marlborough Branch as an hypothetical line from West Acton to Marlborough and Southborough.
The USGS maps have the Vermont and Massachusetts, then known as the Fitchburg, running to just west of Athol, then along the same line as the Vermont and Massachusetts displayed on the kml maps. The Worcester and Nashua runs between Ayer and Pingryville, then the Fitchburg to West Concord. The USGS quads display the Marlborough Branch starting at South Acton and running to Marlborough Junction, where it branches with the Old Colony Railroad. The 1870 kml files have this as the Boston and Worcester, [see Boston and Albany] running to Milford.
October 31 - Milford, Massachusetts - "Artemus Ward"
After Milford, Twain returned to Boston. This would involve the Milford Branch of the B&A to Framingham and the mainline of the B&A to Boston.
