Two items, comprising two hand-corrected pages of London's manuscript for The Cruise of the Snark, along with a signed check from the author. The printed manuscript galley proof pages, 9 x 11.75, stamped "1st Rev.," correspond to pages 28-29 and 32-34 of the first edition of The Cruise of the Snark, and feature about ten words in London's hand: he deletes the conversational musing, "Oh, yes, she was all right, all right"; writes, "cut 2 1/2″ x 4″ will follow in a day or so," in the margin of the second page; substitutes the word "change" for "result"; and substitutes "cook" for "steward." The check, filled out in another hand and signed by London, "Jack London," is payable to the saddler and leather firm J. C. Johnson & Co. for $80, April 28, 1905. In overall very good condition, with creasing, light stains, and several punch holes to the right side. Chronicling London’s 1907 voyage through the South Pacific, The Cruise of the Snark proved to be a popular account that provided insight into a little-known part of the world.
