I regret, indeed, that time has not permitted me to enter more fully on some of the topics introduced, and that of others, I have been obliged to cut them short or omit them altogether, including the subject of their languages, geographical terminology, and personal names, the latter of which is a very curious inquiry of itself. I confess it would have fallen in with my inclinations, as well as my conceptions of the true nature and extent of the inquiries confided to me, to have extended them to other parts of the State, and given a more complete view of our ethnology, had it been practicable to do so before the meeting of the Legislature. I cannot, however, close this note without expressing the hope that the Legislature will authorize you to take further measures for completing the work. There are a large number of the class of antique, circular and elliptical works scattered over the western and southwestern part of the State, of an age anterior to the discovery, which it would be important to examine and describe. These chiefly lie west of Cayuga, and upon the sources of the Susquehanna. Interspersed amid this system of common ring-forts of the west there are some of a still earlier period, which exhibit squares and parallelograms, yet without any defensive work in the nature of bastions. The area of early French occupancy, or attempt at colonization, within the State, extends east and west between the waters of the Cayuga and Oneida lakes, as general boundaries, having the county of Onondaga as its chief and central point. This area will comprehend the most striking part of the numerous remains of implements of art, and other antiquities of European origin, which have heretofore excited attention. How far these evidences extend north is not known. But any examination of either the aboriginal or foreign remains would be incomplete which did not extend also along the line of the St. Lawrence and the waters of Lake Champlain. The valley of the Hudson, and the southern part of the State generally, although it has not been explored with this view, is known to have some antiquarian features worthy examination. And were there none others than the artificial shell mounds and beds on the sea coast and the fossil bones of the valley, so remarkable in themselves, these would alone be entitled to the highest interest in studying the ancient history of the races of man in this area. Geological action subsequent to the period of the habitation of the globe, has not been examined with this view, but is believed to be important in denoting eras of former occupancy; it is known that various parts of the State have yielded, at considerable depths below the surface, many curious evidences of artificial remains, along with relics of the animal and vegetable kingdoms.
