Mixed Edition. C. A. Federer dustjacket art. Important early Blieler listed fantasy and nautical adventure novel by Mason of psychic occurrences on a tropical voyage. Great dustjacket art of spirit guiding a young boy at the helm. Holt presumably used the first edition plates for this copy as the title page states 1920, however "March 1923" has been added to the copyright page to indicate a later printing. Scarce in any case with the original illustrated dustjacket. Very Good-Near Fine with some spotting to lower edge, in Very Good plus dustjacket, few cm sized chips at rear panel, few mild streaks at front panel.
