For Harvey’s biography, see AD, 12 Jan 1906, note at 267.35.

47. Harvey for Harper and Brothers to SLC, 14 Nov 1900, CU-MARK (the term of this 14 November letter agreement was “between this date and January 1st, 1902”); 20 Nov 1900 to Harvey, MH-H; SLC per Harvey to Harvey, 26 Nov 1900, Harper and Row archives, photocopy in CU-MARK.

48. In May 1888, having “spent an hour & a half” with one of Thomas Edison’s recently marketed phonographs “with vast satisfaction,” he tried to leverage his friendship with Edison to secure two of the machines “immediately, instead of having to wait my turn. Then all summer long I could use one of them in Elmira, N. Y., & express the wax cylinders to my helper in Hartford to be put into the phonograph here & the contents transferred to paper by typewriter.” At the end of July, however, when the machines failed to arrive, he canceled the order (25 May 1888 to Edison, NjWoE; SLC per Whitmore to the North American Phonograph Company, 30 July 1888, CU-MARK).

49. SLC 1892; SLC and OLC to Howells, 28 Feb 1891, NN-BGC, in MTHL, 2:637; 4 Apr 1891 to Howells, NN-BGC, in MTHL, 2:641.

50. Lyon 1903–6, entry for 28 Feb 1904. Clemens actually began dictating earlier than 14 January; see “Villa di Quarto”: “I am dictating these informations on this 8th day of January 1904” (233.12–13).

51. 16 Jan 1904 to Howells, MH-H, in MTHL, 2:778–79.

52. Howells to SLC, 14 Feb 1904, CU-MARK, in MTHL, 2:781.

53. 14 Mar 1904 to Howells, NN-BGC, in MTHL, 2:782.

54. “John Hay,” 224.26–39; “The Latest Attempt,” 220.17.

55. Lyon’s longhand notes for these dictations are presumedlost, and one of only two typescripts by Jean Clemens to survive is the first part (twenty-one pages) of the “Villa di Quarto” dictation. With that exception, all the Florentine Dictations are preserved only in typed copies made in 1906 from Jean’s (now lost) typescripts. The dictation about the typewriter was published under the heading “From My Unpublished Autobiography” in Harper’s Weekly for 18 March 1905, and Clemens later inserted it in AD, 27 Feb 1907 (SLC 1905c).

56. See the Textual Commentary for “Villa di Quarto,” MTPO.

57. AD, 6 Aug 1906.

58. 29 Jan 1904 to Stanchfield, CU-MARK.

59. See the ADs of 26 May (Whitford), 2 June (Paige), and 14 June 1906 (Bret Harte).

60. 16 Jan 1904 to Howells, MH-H, in MTHL, 2:779.

61. “Twain’s Plan to Beat the Copyright Law,” New York Times, 12 Dec 1906, 1. The then current copyright law granted protection for twenty-eight years, with one extension of fourteen, for a total term of forty-two years. Clemens thought that if the autobiographical notes were attached to a book at the end of its term, they would create a new publication with its own term of forty-two years, for an overall total of eighty-four years.

62. 21, 22, and 23 Feb 1910 to CC, photocopy in CU-MARK. The “Copyright Act of 1909” passed both houses of Congress on 4 March 1909.

63. MTB, 3:1260–64. The following account of the history of the Autobiographical Dictation series is founded upon and greatly indebted to the ground-breaking research of Lin Salamo, an editor at the Mark Twain Project until 2009.

64 MTB, 3:1266.

65. AD, 9 Jan 1906; Lyon 1906, entry for 25 May; MTB, 3:1266.

66. MTB, 3:1267.

67. If TS1 through TS4 had been preserved in the way they were doubtless left to Paine—as four stacks of consecutively numbered pages—it would long ago have been obvious that each was a discrete sequence.
