At the present stage of my researches it would be too early to write such an account of the ceremonial calendar of the Tusayan villagers, but it has been deemed well to put on record, with many new observations, this preliminary outline of what may be a portion of a general system, to aid other investigators in kindred fields of study. When I began my work, four years ago, the task of bringing order out of what appeared to be a hopeless confusion seemed well nigh impossible, but as one ceremony after another was studied it was found that the exactness of the ritual as exemplified in ceremonial presentations pertained even to details, and that there was a logical connection running throughout all the religious observances of the Tusayan Indians, the presentations of which were practically little influenced by white races with whom the people had been brought in contact. As these ceremonials were studied more sympathetically I discovered a unity throughout them which, whatever their origin may have been, placed them in marked contrast to those of the nomads by whom they were surrounded. They were found to belong to a type or ceremonial area in which the other Pueblos are embraced, the affinities of which carry us into different geographic regions of the American continent. But while this type differs or differed in ancient times from those of Athapascan or Shoshonean aborigines, it bears evidence of a composite nature. It had become so by contributions from many sources, and had in turn left its impress on other areas, so that as a type the Pueblo culture was the only one of its kind in aboriginal America. With strong affinities on all sides it was unique, having nearest kinship with those of Mexico and Central America. The geographic extension of the Pueblo type of culture was no doubt formerly much greater than it is at the present time. What its original boundaries were future investigation will no doubt help us to decide, but the problem at present before us is the determination of its characteristics as a survival in our times. When once this is satisfactorily known, and not until then, can we advance with confidence to wider generalizations as to its past distribution and offer theories regarding its affinities with other ceremonial areas of the American race.
