A complete account of these customs in any tribe will necessitate the witnessing of many funeral rites, as the custom will differ at the death of different persons, depending upon age, sex, and social standing. To obtain their explanations and superstitions, it will be necessary to interrogate the Indians themselves. This is not an easy task, for the Indians do not talk with freedom about their dead. The awe with which they are inspired, their reverence and love for the departed, and their fear that knowledge which may be communicated may be used to the injury of those whom they have loved, or of themselves, lead them to excessive reticence on these subjects. Their feelings should not be rudely wounded. The better and more thoughtful members of the tribe will at last converse freely on these subjects with those in whom they have learned to place confidence. The stories of ignorant white men and camp attaches should be wholly discarded, and all accounts should be composed of things actually observed, and of relations made by Indians of probity. This preliminary volume by Dr. H. C Yarrow has been the subject of careful research and of much observation, and will serve in many ways as a hint to the student. The literature of the subject is vast, but to a large extent worthless, from the fact that writers have been hasty travelers or subjective speculators on the matter. It is strange how much of accepted history must be rejected when the statements are carefully criticised and compared with known facts. It has frequently been stated of this or that tribe that mutilations, as the cutting off of fingers and toes, of ears and nose, the pulling out of teeth, &c., are extensively practiced as a mode of mourning find wild scenes of maiming and bloodshed are depicted as following upon the death of a beloved chief or great man yet among these tribes maimed persons are rarely found It is probable that there is some basis of fact for the statement that mutilations are in rare instances practiced among some tribes. But even this qualified statement needs absolute proof. I am pleased to assure those who will take part in this work by earnest and faithful research that Dr Yarrow will treat them generously by giving them full credit for their work in his final publication. I must not fail to present my thanks to the Surgeon General of the United States Army and his corps of officers for the interest and assistance they have rendered.
