March 14 Thursday – The first of five letters from Hawaii, reprints of five early Sacramento Union letters with “a few minor omissions” ran in the New York Weekly. Dated Mar. 18, 1866, beginning: “We arrived here to-day at noon…” this first article omitted “the short anecdote of Brown’s mistaking a cake of soap for a ‘curious foreign dish’” [The Twainian, Mar. 1944 p2-3]. These letters are notable for their promotional value to Sam’s upcoming New York lecture.

March 13 Wednesday – Sam’s “Volley from the Down-Trodden” ran in the Missouri Democrat [Camfield bibliog.].

March 12, 13 and 15 Friday – Three articles: “Female Suffrage: Views of Mark Twain” first appeared in the St. Louis Missouri Democrat on these days [Budd, “Collected” 1007; MTTMB 287n1].
These were reprinted in the Alta California April 10, 28, and May 11. From two of Sam’s letters on suffrage:

March 7 Thursday – The New York Weekly announced it would print (re-print) a series of Mark Twain’s “inimitable papers.” The weekly reprinted five of Sandwich Islands Letters to the Union, but without mention of the prior publication [MTL 2: 12n3].

March 6 Wednesday – Artemus Ward (Charles Farrar Browne) died of tuberculosis after his last performance on Jan. 23 in London. Ward was 33. He was interred near London but his body was later shipped back to America to be buried at Waterford, Maine. It arrived in New York in May, when Sam noted the event in one of his Alta letters.

March 5 Tuesday – The New York Saturday Evening Express published “Barnum’s First Speech in Congress,” by Mark Twain, on page one [MTL 2: 11-12n3]. Sam arrived in St. Louis at midnight after sitting up for two nights in coach due to full sleeping cars. Sam was returning home after six years and four months. He went directly to his sister Pamela’s house at 12 Chestnut Street, where he “sat up till breakfast time, talking and telling lies.” Sam’s niece, Annie Moffett, was almost fifteen and his namesake nephew, Sammy, was six [Sanborn 320-21; MTL 2: 18n1].

March 3 Sunday – On a snowy night Sam left New York for St. Louis on the 8 o’clock New Jersey Central. It was a 52-hour rail connection. On the same day the New York Sunday Mercury published “The Winner of the Medal,” by “that prince of humorous sightseers, Mark Twain, whose contributions to California light-literature has gained him a front-rank position among the sparkling wits of the Land of Gold” [MTL 2: 11n3, 18n1].

March 2 Saturday – Sam telegraphed the proprietors of the San Francisco Alta California (Fred MacCrellish, William Augustus Woodward (1829?-1885), Orlando M. Clayes (1837-1892), and John McComb). “Send me $1,200 at once. I want to go abroad.” Although the owners were skeptical, it was McComb who argued and won the day for Sam to travel abroad in exchange for letters to the Alta [MTL 2: 17].

March 1 Friday – Sam was invited and attended the opening of the spring season for the grand Bal d’Opera at the new Academy of Music. Sam dressed up in “flowing robes, and purported to be a king of some country or other” [Sanborn 320]. He would become famous for such sartorial exuberance.

February 24 Sunday – Alta California prints Sam’s “Letter from Mark Twain” number 3, dated Dec. 23, 1866, with article “Steamer COLUMBIA at sea” [Schmidt; Camfield bibliog.].
