Over the length and breadth of the American continent a peculiar sanctity is attached by the aborigines to the four points of the compass. This arises from the circumstance that from these quarters come the winds which carry the fertilizing rains. The Red Man, a dweller in vast undulating plains where landmarks are few, recognized the necessity of such guidance in his wanderings as could alone be received from a strict adherence to the position of the four cardinal points. These he began to regard with veneration as his personal safeguards, and recognized in them the dwelling-places of powerful beings, under whose care he was. Most of his festivals and celebrations had symbolical or direct allusions to the four points of the compass. The ceremony of smoking, without which no treaty could be commenced or ratified, was usually begun by the chief of the tribe exhaling tobacco-smoke toward the four quarters of the earth. Among some tribes other points were also recognized, as, for example, one in the sky and one in the earth. All these points had their symbolical colours, and were presided over by various animal or other divinities. Thus the Apaches took black for the east, white for the south, yellow for the west, and blue for the north, the Cherokees red, white, black, and blue for the same points, and the Navahos white, blue, yellow, and black, with white and black for the lower regions and blue for the upper or ethereal world. Indian Time and Festivals The North American tribes have various ways of computing time. Some of them rely merely upon the changes in season and the growth of crops for guidance {132} as to when their annual festivals and seasonal celebrations should take place. Others fix their system of festivals on the changes of the moon and the habits of animals and birds. It was, however, upon the moon that most of these peoples depended for information regarding the passage of time. Most of them assigned twelve moons to the year, while others considered thirteen a more correct number. The Kiowa reckoned the year to consist of twelve and a half moons, the other half being carried over to the year following.
