THE following collection of myths of the Thompson Indians has been in my hands for quite a number of years. Their publication has been delayed because it seemed desirable, on account of the large amount of mythological material brought together by the Jesup Expedition, to devote a whole volume and a complete discussion to this subject. Unfortunately this has not been possible; and it has been necessary to scatter the material in a number of publications, and much of it remains still unpublished. For this reason the present series is given without a detailed comparison, which would have to be repeated and expanded when the references to the unpublished material should become available.
