Much of this reconstruction depends heavily on our knowledge of the later tribes of the Southeast and on broader analogies as well. Archeological proof does not exist for much that we have inferred. Yet we know that what we find here could not have been built by villagers living at the level of bare subsistence. Economic surplus was essential, and we know the Indians had the corn with which to create it. Strong leadership was needed to carry such large projects to completion; and with it there must have been a social and religious class system to organize the economic and priestly functions of such a community. The temple priests and their assistants and retainers would have formed a rather numerous class with high status in a society so clearly impressed with the importance of the physical expression of its religious ideas. Wealth and power may likewise have rested with a specialized warrior class which controlled the governing function of the group, or it may be that these were combined with the religious duties of the priestly class. Whatever the system employed, several hundred unusually important individuals given special burial in the Funeral Mound attest to the distinctions which existed. Class differences of this sort are the most common basis for a high degree of social and political control; and Ocmulgee is a good example of the real attainments of some American Indians along these lines. [Illustration: Ungrooved ax, or celt, of the temple mound builders.] In spite of the relatively large amount of information we have about them, however, we know surprisingly little of the ultimate fate of the Master Farmers. We do know that these first bearers of an alien culture from the Mississippi Valley did not persist very long in the area in terms of its previous history. Within 200 years the busy village was deserted, only to be visited by an occasional traveling band descended from the Early Farmers who had lived on in nearby sections. We do not know even whether the last occupants left here in a body to settle elsewhere, whether they gradually died off, whether they were absorbed into the surrounding population, or whether they were finally exterminated by neighbors who had themselves developed large settled communities capable of effective military action. Other ideas came to Georgia from the Mississippi Valley, but Ocmulgee lay silent and was passed by. Only in the last chapter of Indian history in this State was the site again reoccupied for a brief time. Here at the end, to be described in our final chapter, we find the Creek Indians once more living among the haunts of their ancestors.
