The work occurs on an elevated point of land formed by the junction of a small stream, called Fordham’s brook, with Allen’s creek, a tributary of the Genesee river. Its position is about three miles north of the village of Le Roy, and some ten or twelve northeast of Batavia. The best view of the hill, as one of the natural features of the country, is obtained a short distance north of it, on the road from Bergen to Le Roy. To attain a proper conception of its susceptibilities and capacity, as the site of a work of defence, it is essential to conceive the country, for some distance, to have had the level of the extreme plain, forming the highest part of the fort. The geological column of this plain, after passing down through the unconsolidated strata, appears to be composed of various strata of corniferous limestone, Onondaga or hydraulic limestone, and perhaps Medina sandstone. Geological causes, originating, so far as we can immediately perceive, in the two streams named, have cut down this series of stratifications, on the north, east and west, unequally, to the depth of some eighty or ninety feet, isolating the original plain, on three sides, by the vallies of Allan’s creek and Fordham brook. Availing themselves of this heavy amount of natural excavation, the ancient occupants of it further strengthened its position, by casting up a wall and ditch along the brow of the two vallies, at the points of their junction, from A. to B., 60 rods; from A. to D., 30 rods; and from B. to C. 15 rods. This is as much of the embankment as now remains; but tradition adds, that, on the earliest occupancy of the county, there were evidences that the work had been continued south from the extreme points, C. and D., and connected by an enclosure, parallel to A. B., which would have given it a regular quadrangular shape. The encroachments of the respective vallies, at C. and D., now terminate the trench. And if we concede that geological changes of this kind must have required some time for their production, by the present power of action possessed by the streams named, it is an argument for the antiquity of the work. But, however antique, it was still the effort of a rude, and at best half civilized people, at an epoch when bows and arrows, clubs, spears and stones, and the stone _casse-tete_,[66] were the principal weapons of defence. For these are the chief objects of antiquarian interest dug from the ground. There are also disclosed by the place or its vicinity, the amuletum archæus and other amulets of sea shell, bone and fossil stone, which were so much prized by the ancient red races of this continent, by whom they were manufactured, and exclusively used before the era of the discovery. That the spot continued, however, whether a ruin or not, to be visited or occupied, after this era, is proved by some remains of art, which were found here and described by Mr. Follet, in a letter, which constitutes a valuable part of the materials employed in this
