March 7 Wednesday – According to the Brooklyn Eagle, p. 7, “Samuel L. Clemens (Mark Twain) testified in the libel suit of Captain C.C. Duncan against the New York Times.” Since Sam’s letter of Mar. 9 to Cable referred to a Mar. 8 meeting with Charles Dudley Warner in Hartford, it’s likely that Sam returned from New York either on the evening of Mar. 7 after the billiards match, or the next day.

Karl Gerhardt wrote to Sam & Livy of the arrival of “little Olivia” who was born this evening [MTP].

Roswell Smith wrote from NYC on The Century Co. notepaper: “I send you a note just received from Mr Cable, which is in response to mine as to the Hartford lecture project. / I want him here on the 26th of March to speak on Prison Reform before the Congregational Club if it will not interfere with your plans” [MTP].

March 7–14? Wednesday – Sam wrote from Hartford to Benjamin H. Ticknor directing him to make a few changes on the foundry proof pages of LM. “It ain’t any matter about the 50,000 already printed—no importance” [MTP].
