1845 – From Sam’s Autobiography:
I recall Mary Miller. She was not my first sweetheart, but I think she was the first one that furnished me with a broken heart. I fell in love with her when she was eighteen and I nine—but she scorned me, and I recognized this was a cold world….I soon transferred my worship to Artimisia Briggs, who was a year older than Mary Miller. When I revealed my passion to her she did not scoff at it. She did not make fun of it. She was very kind and gentle about it. But she was also firm, and said she did not want to be pestered by children.

And there was Mary Lacy. She was a schoolmate. But she was also out of my class because of her advanced age. She was pretty wild and determined and independent. She was ungovernable, and was considered incorrigible. But that was all a mistake. She married, and at once settled down and became in all ways a model matron…[AMT 2: 212-13].

January 24 Friday – Sam witnessed the premeditated murder of “Uncle” Samuel Smarr (1788?-1845), shot at close range by William P. Owsley. Smarr was carried into the drugstore of Dr. Orville Grant, the very house that poverty would soon force the Clemens to move into. Sam squeezed into the room where they laid the dying Smarr and watched [Wecter 106]. Note: The scene would be grist for Colonel Sherburn’s cold-blooded killing of Boggs, the town drunk, in chapters 21-22 of Adventures of Huckleberry Finn.

February 24 Monday – Hannibal, Mo. was granted a city charter [Hannibal Courier-Post, Mar. 6, 1935 p10b].

March 19 Wednesday – From the Hannibal, Mo. Library web site: “In 1840 many citizens of Hannibal, Missouri felt a need for a public library. Judge John Marshall Clemens (Mark Twain’s father), Zachariah Draper (1798-1856), Dr. Hugh Meredith, and Samuel Cross (1812-1886) took on the responsibility of this task. They organized the Hannibal Library Institute. On March 19, 1845 this library was chartered by the General Assembly of Missouri. The books were kept in Dr. Meredith’s office in a building at the corner of Main and Bird Streets. This was not a free library.

Summer – Sam stowed away on a steamboat headed south. He was found by a crewmember and put ashore thirty miles down river, at the town of Louisiana, Mo. There he spent the night with Lampton relatives. The next day they returned him home.

August 24 Sunday – In Hannibal, John Marshall Clemens wrote to Orion in St. Louis. He enclosed a course of twenty oral lectures on grammar by Professor Hull. John was taking Hull’s class and promised to outline the material and send it on to Orion, who might benefit in the printer’s trade from such lessons. Sam was nearly ten years old and probably received the same instruction at home [MTBus 9-10].

August 25-26 Tuesday – The Philadelphia North America reported on Aug. 26, “Affray at Hannibal, Mo.”—a fight between Dr. Orville R. Grant and a man named Railey, who stabbed Grant with a spear attached to his cane. In his Dec. 2, 1906 A.D. Sam recalled the man’s name as Dr. Reyburn [AMT 2: 590].

Fall – In either 1844 or 1845, Sam left the dame school for a “good common school” on Center Street near the town square, taught by a middle-aged Irishman, William O. Cross [Powers, D. Waters 93].

November 6 Thursday – Record of Jimmy Finn’s death [MTP].
