Note: Published as a serial in Young Folks' Paper with illustrations by W. Boucher, year unknown. (Wikipedia lists five successive titles of the UK "weekly children's literary magazine" Young Folks (1871 to 1897), including Young Folks' Paper through June 1891.) The 1892 Chambers edition text "is somewhat rearranged and is condensed by about 2000 words" according to L. W. Currey. It is published with a subtitle under the author's fullname, with some or all of the original illustrations. The publisher acknowledges, "The illustrations are reproduced with kind permission of the Proprietor of Old and Young (formerly Young Folks' Paper), in which the story appeared in serial form." --undated title leaf (viewed at HathiTrust) The 1893 US ed. is identical to the 1892 Chambers, apparently from WorldCat records and newspapers.

Synopsis: "In this tale the Pole is actually discovered in the middle of a fertile country, and the air of probability for this startling finale is ingeniously preserved throughout the story." --The Spectator 1892-10-29, p. 604 The cost is detail of the arctic expedition, probably too much for rousing fiction, according to this reviewer.
