The process briefly sketched above explains the way in which village ruins have their origin; a band of 500 village-building Indians might leave the ruins of fifty villages in the course of a single century. It is very doubtful whether the total number of Pueblo Indians ever exceeded 30,000. This is the figure stated by Mr. A. F. Bandelier, whose intimate acquaintance with the eastern part of the pueblo region gives his opinion great weight. The apparently trifling causes which sometimes result in the abandonment of villages have been already alluded to. The lower Verde forms no exception to the general rule sketched above. Scattered along the river, and always located on or immediately adjacent to some area of tillable land, are found many small ruins, typical examples of which have been described in detail. These form the subordinate settlements whose place in the general scheme has been indicated. The masonry is generally of river bowlders only, not dressed or prepared in any way. The number of these settlements is no greater than would be required for one complete cycle or period, although the evidence seems to support the hypothesis that the movement commenced in the northern part of the region and proceeded southward in two or perhaps three separate steps. It is possible, however, that the movement was in the other direction. This question can be settled only by a thorough examination of the regions to the north and south. There are two, possibly three, points in the region discussed where a stand was made and the various minor settlements were abandoned, the inhabitants congregating into larger bands and building a larger village for better defense against the common foe. These are located at the extreme northern and southern limits of the region treated, opposite Verde and near Limestone creek, and possibly also at an intermediate point, the limestone ruin above Fossil creek. These more important ruins are all built of limestone slabs, and the sites are carefully selected. The internal evidence supports the conclusion that the movement was southward and that in the large ruin near Limestone creek the inhabitants of the lower Verde valley had their last resting place before they were absorbed by the population south of them, or were driven permanently from this region. The strong resemblance of the ground plan of this village to that of Zuñi has been already commented on, and it is known that Zuñi was produced in the way stated, by the inhabitants of the famous “seven cities of Cibola,” except that in this case Zuñi was the second site adopted, the aggregation into one village, or more properly a number of villages on one site, having taken place a few years before. The fact that Zuñi dates only from the beginning of the last century should not be lost sight of in this discussion.
