1 Clemens and Petroleum V. Nasby were in Boston together on 14 and 15 March. James Clark Redpath (1833–91), author, journalist, abolitionist, social reformer, and educator, founded the Boston Lyceum Bureau (later the Redpath Lyceum Bureau) in 1868, in partnership with George L. Fall (d. 1874 or 1875), to supply the need for a central booking agency for lecturers. The date of this letter fragment establishes the beginning of Clemens’s long, congenial association, both personal and professional, with Redpath, who replied on 24 April (see 10 May 69 to Redpath, n. 1). The Lyceum Bureau also represented many of the other leading speakers of the day, including, by 1870 at least, Nasby (Eubank, 84, 89–99, 103–6, 114, 295–98; Horner, 141–55, 175, 180–81).
