There is an apparent extension of the system of works which characterize the fort and mound period of the Ohio valley, reaching from the Alleghany waters in Chautauque and Cattaraugus, along the southern shore of Lake Erie, indefinitely eastward, which it would be interesting to trace. One of the most reliable proofs of eras and races of men is found in the remains of art. There are some striking coincidences in this respect between the antiquities of New-York and the Mississippi valley, which denote precisely the same state of arts and the same eras of occupancy. Such are the Minace Alleghanic which occurs alike in the Grave Creek mound and the simple places of sepulture in Onondaga, the Nabikoaguna Antique, which has been found at Upper Sandusky and at Onondaga; and the Medaëka Missouri, from the valley of the Sciota, in Ohio, and the Kasonda in New-York. Accurate descriptions of the whole class of our antiquarian remains could not, if thoroughly executed, but throw much light on, and introduce precision in, periods of remote history in this State, and indeed the continent, which are now either involved in obscurity, or constitute themes of mere conjecture. I. HISTORICAL AND ETHNOLOGICAL MINUTES. MADE ON TAKING THE CENSUS OF THE IROQUOIS OF NEW-YORK, IN CONFORMITY WITH AN ACT OF THE LEGISLATURE, IN 1845. [_a._] A Sketch of the Iroquois Groupe of Aboriginal Tribes. On the discovery of North America, the Iroquois tribes, were found seated chiefly in the wide and fertile territory of western and northern New-York, reaching west to the sources of the Ohio;[10] north, to the banks of Lake Champlain and the St. Lawrence; and east, to the site of Albany. They had as much nationality of character, then, as any of the populous tribes, who, in the 4th century wandered over central and western Europe. They were, in a high degree, warlike, handling the bow and arrow with the skill and dexterity of the ancient Thracians and Parthians. They were confederated in peace and war, and had begun to lay the foundations of a power, against which, the surrounding nations, in the Mississippi valley, and along the St. Lawrence, the Hudson, and the Delaware, could not stand. The French, when they effectually entered the St. Lawrence in 1608,[11] courted their alliance on the north, and the Dutch did the same in 1609, on the Hudson. Virginia had been apprised of their power, at an early day, and the other English colonies, as they arrived, were soon made acquainted with the existence of this native confederacy in the north. By putting fire-arms into their hands, they doubled the aboriginal power, and became themselves, for more than a century, dependant on their caprice or friendship. [10] They always denominated the Alleghany river by the name of Ohio. This I found to be the term constantly used for that river in 1845. They give the vowel i, in this word, the sound of i, in machine. [11] They actually discovered this river, in 1535.
