January 21 Monday to March 30, 1861 – Ten letters signed by Quintus Curtius Snodgrass were published on various dates in the New Orleans Daily Crescent. Until 1964, most scholars attributed these letters to Sam. Alan Bates then presented an article showing that the dates penned and published would have precluded them from being Sam’s [Bates 31-7]. Could Sam have assigned them dates different than the day of composition? Or, are they, as Bates claims, “the tedious productions of an obscure newspaper reporter”?

January 29 Tuesday – The Alonzo Child left for St. Louis.

February 5 Tuesday – The Alonzo Child arrived in Cairo, and did not continue to St. Louis due to icy river conditions.

Sam was recommended by John M. Leavenworth (b.1835?) brother of Zeb, and John T. “Tom” Moore. Sam Clemens was duly elected to receive the Masonic first degree [Jones 364; Strong 88].
Note: Moore was a “mud clerk” on the Roe; see July 6, 1859 and Feb. 18, 1861; also letter from Karl Gerhardt of May 5, 1909 mentioning Moore.

Church’s oil painting, Heart of the Andes. He also wrote of his mother’s disapproval of a dance, the Schottische (like the Polka) that he, his sister, and Miss Castle took part of [MTL 1: 116]. Note: The source for this letter in the printed volume was Paine’s text; Here are transcribed parts of the letter that have surfaced since, from MTP’s “drop-in” letter file, as follows:
