While the Kiowa note the changes of the moon and have a fixed name for each moon or lunar month, it is not to be supposed that their system could have the exactness of the calendar systems of the more cultivated nations of the south, or perhaps even of the sedentary tribes of the east, whose interests so largely depended upon noting carefully the growth and ripening of crops, the appearance of the various species of fish in the streams, etc. Nevertheless, they have a system, imperfect though it be, and it can not be said of them, as Matthews says of some northern tribes, that "they have no formal names for the lunar periods." In this, as in other matters of tribal lore, they defer to the superior knowledge of certain old men who assume the position of experts on the subject. The Kiowa recognize twelve or more moons or months, beginning the year, according to one authority, with the first cold weather, about the end of October, or according to other authority, with the first snowfall, about a month or more later. They have seven distinct moon or month names, and some of these are duplicated and distinguished as _great_, _small_, or of _summer_, to make the full number for the year. These moons of course do not coincide closely with our calendar months, and as the system is necessarily imperfect, there is a discrepancy of authorities, some recognizing twelve moons while a few count as many as fourteen or fifteen, the additional names being a further duplication of some of the others, as already explained; all authorities agree on the first eight as here given, and all but one agree on the ninth, after which there is a discrepancy. The author has made no arbitrary attempt to harmonize conflicting statements, as the result would be artificial and not aboriginal; and we must expect a certain amount of uncertainty and disagreement on such a complicated subject, among primitive people. Our own calendar system has been of slow growth, and more than one hundred million Europeans still refuse to accept it. The list here given is that obtained from Anko, the best calendar authority in the tribe, and is that generally accepted by the Kiowa. By means of tally dates from his picture calendar their periods can be pretty closely assigned, although, as will be noticed, even he varies a month in some instances in the course of three years. Some of the old men put another moon, _Pai Ka`gúăt P'a Sän_ (see number 5), between _Pai Gáñhíña P'a_ and _T'águñ´ótal P'a Sän_.
