The symbols appended to the songs, and among which the forms of the rectangle and circle frequently occur, end with the fifth song; they appear very arbitrary, and it is certainly disappointing to find that they bear no resemblance to the carvings upon the Lenape stone, likewise, as we have supposed, productions of the Lenni Lenape and dealing with the same subject. Yet we need not be surprised when we consider the varied and often arbitrary methods of Indian picture-writing. In comparing the carvings on the reverse of the Lenape stone with the Lenape and Huron-Iroquois traditions of their early migration and struggle with the mound-builders, we have spoken only of probabilities. Possibly these carvings may refer to the incantations of the prophets and doctors, to songs for "medicine hunting," or charms against evil spirits, and not to the history of the tribe, as recounted in the Wallum Olum and the narratives of Heckewelder and Cusic. Possibly, too, the modern Indians who have seen the carvings may have entirely mistaken their subject, as similar signs are used in quite different kinds of their picture-writing. Yet if we view the chief feature of the Lenape stone--the mammoth picture--as an example of muzzinabik or historical picture-writing, an attempt to explain the carvings on the reverse of the stone as specimens of the same class of writings does not seem extravagant. Viewed in the light of these legends, and compared with the fragments of ancient Indian history which chance has preserved to us, the carvings upon the Lenape stone vividly impress upon our minds the reality of that dark period of our continent's past, antecedent to the first coming of the white man, separated from us by but a few centuries, yet where the boundary line between history and geology becomes indistinct, when for hundreds, perhaps thousands, of years the Indian lived alone on the "great island," and while those deep-rooted peculiarities of his character, which civilization has failed to eradicate, were slowly growing out of his wilderness life. The ancient presence of the Lenape is often remembered in the heart of his former dominions. Along the shores of the beautiful river, whose transatlantic name, applied also to his tribe, he resented, the arrow-head and tomahawk, everywhere found upon sites of ancient camps and fishing-grounds, tell of the long centuries of his possession. His memory lingers in the name and poetry of our Indian summer; and in that most delightful of autumnal seasons, when a warm wind blowing from the abode of the Great Spirit stirs the fields of ripened maize, we may see, where first the Indian's fancy must have seen it, a suggestion of his head-dress of feathers in the graceful motion of the corn-stalks. He is immortalized in richly melodious names of rivers, streams, and mountains, and his memory is forever recalled in the yearly growth of that noblest of American plants, the Indian corn.
