The Lowell Daily Courier published a review of the show on November 12, 1884, thus establishing the date of the show as November 11.
"Mark Twain followed and he, too, had something to say about the programme, and his determination not to be bound by it. This appears to be a part of the performance, as the readers have objected in other places to the bill and changed it to suit their own notions. Mr. Clemens proved a decided change from the style of his partner. While Mr. Cable was refined to a degree, and of polished manner, the witty Connecticut man was much broader in his humor and less graceful in his work. He was not free from affectation, and some detected an imitation of A. Ward. He told the story of “King Sollermun,” related an anecdote not on the bill, and read the “Tragic Tale of the Fishwife,” “A Trying Situation” and “A Ghost Story.” The laughter was constant throughout, and the audience evidently found their enjoyment of the Twain characteristics much increased by the peculiar delivery of the reader. The explosive ending of the ghost story startled half the people from their seats. Altogether the performance was very enjoyable."
Sam was apparently staying in Boston as he addressed a letter to Pond from there on this date [MTP].
Apparently after the Lowell show Sam wrote to Livy from Lowell, dated November 12
"Livy Darling, only a word, to say I have not heard from you since I left you stricken & lonely in the forever accursed town of Springfield—the only town where we have suffered a defeat. I have not heard from you, & it has depressed me all day. It is now midnight, & has been a hard day. Good night my love. Sam [MTP]."
