Walking to Boston with Twichell: Day By Day
November 12 Thursday – A half-hour later than planned, Sam and Twichell set off at 8:30 AM to walk the 100 miles to Boston. Two and one-half hours later, Sam wrote from Vernon, Conn. to Livy.
“The day is simply gorgeous—perfectly matchless. And the talk! Our jaws have wagged ceaselessly, & every now & then our laughter does wake up the old woods” [MTL 6: 277-8].
November 13 Friday – Sam wrote from New Boston, Conn. to Livy.
Livy darling, it is bitter cold weather. We got up at half past 5 this morning, took breakfast & cleared out just as the dawn was breaking. It was a magnificent morning; the woods were white with frost, & our hands wouldn’t keep warm—nor ourselves either….We shall take the train & be in Boston at 7 this evening.
November 14 Saturday – Sam wrote from Boston to Livy about the “royal time at Howells’ last night.” He enclosed a hanky for the “Modoc” (he wrote “hakky,” as Susy pronounced it).
November 15 Sunday – Sam rested at the hotel while Twichell walked the nine miles to Newton Highlands and preached a sermon, then spent the night with Rev. S.H. Dana, a local pastor [MTL 6: 284n2].
November 16 Monday – Twichell returned to Boston and with Sam and Frederick B. Allen, a Boston friend of Twichell’s. They attended an 11 AM meeting of the Radical Club. Walter Allen of the Boston Daily Advertiser probably invited the men [MTL 6: 284n3].
