With these observations, we are prepared to examine the evidence that points to the site of the Iroquois fort. When the expedition, emerging from Quinté Bay, arrived at the eastern end of Lake Ontario, at the point where the lake ends and the River St. Lawrence begins, they crossed over the lake, passing large and beautiful islands. Some of these islands will be found laid down on the map of 1632. They then proceeded, a distance, according to their estimation, of about fourteen leagues, to the southern side of Lake Ontario, where they landed and concealed their canoes. The distance to the southern side of the lake is too indefinitely stated, even if we knew at what precise point the measurement began, to enable us to fix the exact place of the landing. They marched along the sandy shore about four leagues, and then struck inland. If we turn to the map of 1632, on which a line is drawn to rudely represent their course, we shall see that on striking inland they proceeded along the banks of a small river to which several small lakes or ponds are tributary. Little Salmon River being fed by numerous small ponds or lakes may well be the stream figured by Champlain. The text says they discovered an excellent country along the lake before they struck inland, with fine forest-trees, especially the chestnut, with abundance of vines. For several miles along Lake Ontario on the north-east of Little Salmon River the country answers to this description.--_Vide MS. Letters of the Rev. James Cross, D.D., LL.D._, and of S. D. Smith, _Esq._, of Mexico, N.Y. The text says they continued their course about twenty-five or thirty leagues. This again is indefinite, allowing a margin of twelve or fifteen miles; but the text also says they crossed a river flowing from a lake in which were certain beautiful islands, and moreover that the river so crossed discharged into Lake Ontario. The lake here referred to must be the Oneida, since that is the only one in the region which contains any islands whatever, and therefore the river they crossed must be the Oneida River, flowing from the lake of the same name into Lake Ontario.
