and the limitations of space, have made this method Impossible. References have in every case, however, been given; so that those who wish to consult the fuller or original forms of the tales can do so easily. These references, and all notes, have been put into an Appendix at the end of the volume, thus leaving the pages unencumbered for those who wish only to get a general idea of the subject. The Bibliography has, with few exceptions, been restricted to the titles of original publications; reprints and popular and semi-popular articles and volumes have been omitted. Every care has been taken to make the large number of references correct, though it is too much to hope that errors have not crept in.
In the brief discussions at the end of each section, and again at the end of the volume, we have sought to draw conclusions in regard to the probable origin of some of the myths and to point out the evidences of transmission and historical contact which they show. Merely to present the tales without offering any suggestions as to how they had come to be what they are and where they are, seemed to fall of attaining the full purpose of this series. No one Is more conscious than the author that the hypotheses offered will not meet with universal acceptance; that they rest, in many cases, upon uncertain foundations; and that, plausible as they may look today, they may be fundamentally modified by new material and further study. Should this essay only serve to stimulate interest In this field, and lead to greater activity in gathering new material while yet there is time, he will be quite content.
