Upon discovering the approach of the herdsmen and horses many of the women and children, too impatient to await the gathering of them in the corral, hasten to the valley to join the cavalcade, and upon reaching the party they at once scramble for the wood rats (_Neotoma_) which hang from the necks of the horses and colts. The men of the village are also much excited, but they may not participate in the frolic. From the time the herders leave the village until their return they are on the lookout for the _Neotoma_, which must be very abundant judging from the number gathered on these trips. The rats are suspended by a yucca ribbon tied around the necks of the animals. The excitement increases as the horses ascend the hill; and after entering the corral it reaches the highest point, and the women and children run about among the horses, entirely devoid of any fear of the excited animals, in their efforts to snatch the rats from their necks. Many are the narrow escapes, but one is seldom hurt. The women throw the lariat, some of them being quite expert, and drawing the horses near them, pull the rats from their necks. Numbers fail, but there are always the favored few who leave the corral in triumph with as many rats as their two hands can carry. The rats are skinned and cooked in grease and eaten as a great delicacy. [Illustration: FIG. 9.—Women sprinkling the earth.] COSMOGONY. The Sia have an elaborate cosmogony, highly colored with the heroic deeds of mythical beings. That which the writer here presents is simply the nucleus of their belief from which spring stories in infinite numbers, in which every phenomenon of nature known to these people is accounted for. Whole chapters could be devoted to the experiences of each mythical being mentioned in the cosmogony.
