The tribes of Arizona, among whom religion and ceremonial rites have attained a pre-eminent place, occupy a special position; their time-reckoning has developed into a ceremonial year. However the natural foundation peeps through. Among the Hopi thirteen names with the addition _mü’iyawu_, ‘moon’, are given, so that genuine moon-months must be implied. The second part of _ücü_, October, is said to be called _tü’hoe_; if this is recognised as a month, there are 14 of them. Several of the priests say that there are 13 months, others 12, still others 14. It is to be noted that the seasons and the festivals are determined by observation of the sun in relation to certain terrestrial marks; of these sun-points there are 13. The names of the months are not translated: several recur, but not in the same order, 1 = 8, 2 = 10, 5 to 7 = 11 to 13. But it is stated also that the months are divided into ‘named’ and ‘nameless’[755]. The Zuñi divide the year into two seasons, each consisting of six months. The months are:--December, turning or looking back (of the sun); January, limbs of trees broken by snow; February, no snow in the road; March, little wind month; April, big wind month; May, no name. The same names are said to recur in the second half-year![756] This can only be an entirely conventional arrangement. But according to other sources the six later months, though called ‘the nameless’, have ritualistic names (Yellow, Blue, Red, White, Variegated, Black) derived from the colours of the prayer-sticks offered up at every full moon to the gods of the north, west, south, east, zenith, and nadir, who are represented by these colours[757]. The Pima have 12 months. Two different lists from two natives are given. (I):--1, saguaro harvest moon; 2, rainy; 3, short planting; 4, dry grass; 5, winter begins; 6, yellow; 7, leaves falling; 8, cottonwood flowers; 9, cottonwood leaves; 10, mesquite leaves; 11, mesquite flower; 12, black seeds on saguaros. (II):--1, wheat harvest moon; 2, saguaro harvest; 3, rainy; 4, short planting; 5, dry grass; 6, windy; 7, smell; 8, big winter; 9, gray; 10, green; 11, yellow; 12, strong[758]. The names of colours recur, but seem here to have reference to the seasons. That the wheat culture has been newly introduced does not by any means imply that the series of months is of recent origin, but only points to the familiar instability of their names.
