The circumstances attending the composition of this record and its recent discovery are fully detailed in the introductory chapters. There also, and in the Notes and Appendix, such further explanations are given as the various allusions and occasional obscurities of the Indian work have seemed to require. It is proper to state that the particulars comprised in the following pages respecting the traditions, the usages, and the language of the Iroquois (except such as are expressly stated to have been derived from books), have been gathered by the writer in the course of many visits made, during several years past, to their Reservations in Canada and New York. As a matter of justice, and also as an evidence of the authenticity of these particulars, the names of the informants to whom he has been principally indebted are given in the proper places, with suitable acknowledgment of the assistance received from each. He ventures to hope that in the information thus obtained, as well as in the Book of Rite's itself, the students of history and of the science of man will find some new material of permanent interest and value.
