ELISSA: THE DOOM OF ZIMBABWE first appeared serially in THE LONG BOW between February 2 and June 9, 1898, and 33 illustrations by F.H. Townsend were included. I do not own this serialization.
ELISSA appeared first in book-form in the Longmans, Green, and Company British edition, BLACK HEART AND WHITE HEART AND OTHER STORIES, but with only 8 of Townsend's illustrations.
McKay and Scott both claim that Longmans published ELISSA, together with BLACK HEART AND WHITE HEART, in New York on June 15, 1900. This American edition has the same 8 illustrations for ELISSA.
BLACK HEART AND WHITE HEART first appeared in the New Year's Number of THE AFRICAN REVIEW for 1896. Charles Kerr provided 6 illustrations, but only 5 of the 6 illustrations are found in this American first edition. I do not own the serialization.
This American edition does not contain THE WIZARD, for Longmans already published this story in New York back in 1896.
