The authors are under many obligations to Mr. Alfred Sumner, a native African now in this country at college, whose intimate acquaintance with the life and customs of his people proved most helpful; also to Rev. D. F. Wilberforce, a native missionary, who has long been interested in the oral literature of his country, and in consequence has been able to give us suggestions of unusual value. To Miss Minnie Eaton of Moyamba Mission, and to other friends, who spared no pains to place desired information within our reach, and especially to the Mission boys and girls in Africa whose sympathetic interest made this collection a possibility, the gratitude of the authors is due.
