This Delaware village evidently stood not far from the present town of Springfield, Green County, Missouri. Just beyond it began the "Kickapoo prairie, which is the commencement of that immense chain of prairie land that extends in broken patches to the Rocky Mountains." (Op. cit., p. 70.) The preceding reference to various figures cut on the trees near the deserted village tends to recall a somewhat similar allusion by Irving. On November 2, 1832, during his "Tour on the Prairies," so he wrote: "We came out upon an extensive prairie, and about six miles to our left beheld a long line of green forest, marking the course of the north fork of the Arkansas. On the edge of the prairie, and in a spacious grove of noble trees which overshadowed a small brook, were traces of an old Creek hunting camp. On the bark of the trees were rude delineations of hunters and squaws, scrawled with charcoal; together with various signs and hieroglyphics, which our half-breeds interpreted as indicating that from this encampment the hunters had returned home." (Irving, Washington. (1), p. 187.) It is to be regretted that all such figures should so soon have disappeared, as did the frail structures of the native villages, leaving only fragments of pottery and bits of stone, ashes, and occasional animal bones to indicate where they had once stood. SIOUAN TRIBES. The numerous and widely scattered tribes belonging to the Siouan linguistic family formerly had a combined population which caused this to rank as the second largest stock north of Mexico, being exceeded only by the Algonquian. All evidence tends to prove that during past centuries the many tribes who were found living west of the Mississippi when the great central valley of the continent first became known to Europeans had, within a few generations, migrated from the eastward. This is likewise indicated by certain tribal traditions. Many had undoubtedly occupied the upper parts of the Ohio Valley, and were probably the builders of the great earthworks discovered in that region. What impelled the westward movement of the tribes may never be determined. Whether they were forced to abandon their early habitat by stronger forces, by the lack of food which made it necessary for them to seek a more plentiful supply, or by reason of causes distinct from either of these can never be definitely known. But some remained in the east; all did not join in the migration, and the native tribes encountered by the colonists living in the piedmont region of Virginia and extending southward into Carolina belonged to this linguistic family. Their villages have been mentioned in a former publication. (Bushnell, (1), pp. 92-94.)
