E. represents the Twin Mounds, two natural formations of fine gravel and other diluvial strata, situated on the south side of the creek, on the farm of Jeremiah Gould. These mounds are conspicuous features in the landscape, from their regularity, and position on elevated grounds, as well as from their connection with the ancient Indian history of the valley. These pyramidal heaps of earth are connected, by a neck of earth, in the manner represented. They exhibit the appearance of having been cleared of the forest, almost entirely, at an ancient date. The surface exhibits numerous pits or holes, which excite the idea of their having served as a noted locality for the Indian Assenjigun, or pit for hiding or putting _en cache_, corn or other articles, to preserve it from enemies, or as a place of deposit during temporary absences from the village. There can, I think, be little question that this was the true use and relation these geological eminences bore to the ancient town on the Kasonda, marked B. Such, too, is the general impression derived from local tradition. Some years ago, a skeleton was exhumed from one of these _caches_. [_c._] Antiquities of Pompey and adjacent parts of Onondaga county. No part of western New-York has furnished a larger number of antiquarian remains, or been more often referred to, than the geographical area which constituted the original town of Pompey. There is, consequently, the less need of devoting elaborate attention to the details of this particular locality. It was first visited and described by De Witt Clinton, in 1810-11,[61] and the plough has since rendered it a task less easy than it then was, to examine the lines of its ancient works and its archæological remains. It is quite evident, from the objects of art disclosed at and about these antique sites of security and defence, that civilized man dwelt here in remote times, and there must be assigned to this part of the State a period of European occupancy prior to the commonly received historical era of discovery and settlement, or, at least, if falling within it, as there is now reason to believe, yet almost wholly unknown, or forgotten in its annals. Sismondi has well remarked, that only the most important events come down to posterity, and that fame, for a long flight, prepares to forget every thing which she possibly can. That no accounts should remain of obscure events, in a remote part of the country, at an early date, is not surprising. As it is, we must infer both the dates and the people, from such antiquarian remains of works of art and historical comparisons as can be obtained. [61] Trans. of Philo. and Lit. Society of New-York.
