7 typed single-page letters from Charmian London to John A. Browne of the Vallejo Yacht Club. All signed by Charmian as "Mrs. Jack", Charmian K. London, or both. All with the rubber stamp address in upper corner of "Jack London / Glen Ellen / Sonoma Co., Cal."

Mr. Browne apparently looked after the London's 40-year old 30-foot sailing yacht "Roamer" purchased for $175 the previous year and which they berthed in Vallejo. The letters all treat various matters concerning the Roamer's upkeep and outfitting, London's sailing plans, other travel plans, hectic schedules, etc. The tone of the letters is chatty, friendly and revealing of the importance the "Roamer" held in the London's busy life. Some matters of a social nature concerning Mr. Browne and others are also addressed. The second letter, dated May 17, 1911 concludes "We are in a terrible rush preparing for our driving trip . . ."; in reference to the trip from Glen Ellen to Oregon and back taken by Jack, Charmian, and their servant Nakata in a Studebaker wagon pulled by a team of 4 horses. Jack's account of the adventure was published in Sunset Magazine, Sept. 1911.
