Metropolitan Hall in Sacramento on October 11

August 14–19 Sunday – In his letter completed Aug. 20 to his mother, Sam wrote that he’d been to Sacramento to square accounts [MTL 1: 353]. The exact date of his return took place within this five-day period. He was paid a bonus for his scoop of the Hornet disaster [MTL 1: 355n6]. Sam came down from Sacramento on the steamboat Capital, where he found a pamphlet issued by an insurance company about various insurable risks.

October 11 to November 27 Tuesday – Sam and Denis McCarthy, former part-owner of the Territorial Enterprise, (who Sam now labeled “The Orphan,” quickly organized a lecture tour in California and Nevada. (Lorch gives strong reasoning that the subsequent lecture tour was most likely organized well before this Oct. 2 debut [35-6]). The lecture, titled “Sandwich Islands” made sixteen engagements between these dates at locations where Sam was well known [Sanborn 298-9]. Dates in Silver City, Dayton, and Washoe were canceled.
