The vowels ‘a, ‘e, ‘i, ‘o, ‘u, and their modifications are styled initially exploded vowels for want of a better appellation, there being in each case an initial explosion. These vowels can not be called “breaths,” as no aspiration is used with any of them; nor can they be spoken of as “guttural breaths,” as they are approximately or partially pectoral sounds. They have been found by the author not only in the Siouan languages, but also in some of the languages of western Oregon. In 1880 a brother of the late Gen. Armstrong, of Hampton, Va., who was born on one of the Hawaiian islands, informed the author that this class of vowel sounds occurred in the language of his native land. ABBREVIATIONS.

CHAPTER II. DEFINITIONS. ALLEGED BELIEF IN A GREAT SPIRIT. § 4. It has been asserted for several hundred years that the North American Indian was a believer in one Great Spirit prior to the coming of the white race to this continent, and that, as he was a monotheist, it was an easy matter to convert him to Christianity. Indians have been represented as speaking of “The Great Spirit,” “The Master of Life,” etc., as if the idea of the one and only God was familiar to our aborigines during the pre-Columbian period. While the author is unwilling to commit himself to a general denial of this assertion, he has been forced to conclude that it needs considerable modification, at least so far as it refers to the tribes of the Siouan stock. (See §§ 7, 15, 21-43, 72-79, 92-99, 311, 312, 322-326, 341-346.) On close investigation it will be found that in many cases Indians have been quick to adopt the phrases of civilization in communicating with white people, but in speaking to one another they use their own terms. The student of the uncivilized races must ever be on his guard against leading questions and their answers. The author has learned by experience that it is safer to let the Indian tell his own story in his own words than to endeavor to question him in such a manner as to reveal what answers are desired or expected. § 5. In 1883 the author published an article on “The Religion of the Omahas and Ponkas,” in The American Antiquarian of Chicago. Since then he has obtained additional data, furnishing him with many undesigned coincidences, which lead him to a broader view of the subject. PHENOMENA DIVIDED INTO HUMAN AND SUPERHUMAN.
