Pausing to point out that fig. 28, reproduced from Mexican Codices, shows curious topographical drawings resembling a spider’s net, I will not recount the many disappointments of the wanderers, who were evidently driven away from several places of settlement by earthquakes, but will refer to the Zuñi custom of “annually testing the stability of the Middle in middle time ... when the sun reached the middle between winter and summer ... a shell was laid by the sacred fire of the north.... When during solemn chanting no trembling of the earth ensued, the priests cast new fire and ... dwelt happily feeling sure that their sacred things were resting in the stable middle of the world.” At the beginning of this paper I referred to the powerful hold that the realization of the fixity of the pole star would naturally have exerted upon the mind of primitive man, and I can produce no more striking illustration of this and of my view that the idea of central government and organization had been suggested by Polaris, than this account of the earnest and prolonged search of these ancient people for the stable centre of the earth, on which to found a permanent centre of terrestrial rule or the plan of the celestial government. At the same time it seems to me that the longing for a stable and fixed residence would naturally have been most intense amongst people who had experienced terrible earthquakes and been driven out of their original abodes by their repeated destruction. It is unnecessary to mention the well-known fact that whilst earthquakes prevail throughout North and Central America, the most impressive trace of catastrophes of the kind are connected with the gigantic volcanoes of Central Mexico and Guatemala. With a sympathetic insight into the disasters which seem to have driven the wandering tribes from one region to another and filled them with a passionate yearning for a centre of rest, let us now learn from Mr. Cushing how they planned their metropolis and organized themselves, when they had found the long-looked-for goal, in the Zuñi valley and “settling there, built seven great cities therein. “All their subtribes and lesser tribes were distinctively related to and ruled from a central tribe and town through priest chiefs representatives of each of these, sitting under supreme council or septuarchy of the ‘Master priests of the house’ in the central town itself, much as were the divisions and cities of the great Inca dominion in South America represented at and ruled from Cuzco, the central city and power of them all.
