All this region, and the lands westward beyond the Central Lake District of New York, was the home of that noted Indian Confederation of America which the French named the Iroquois. When the earliest French explorers found them, they were the "Five Nations"--the Senecas, Cayugas, Onondagas, Oneidas and Mohawks. Their name as a league was Hodenosaunee, meaning "they form a cabin,"--this being their idea of a combination, offensive and defensive, and within their figurative cabin the fire was in the centre at Onondaga, while the Mohawk was the door. They were great warriors, and their tradition was that the Algonquins had driven them from Canada to the south side of Lake Ontario. Subsequently a portion of the Tuscaroras came up from the South, and being admitted to the Confederacy, it became the "Six Nations." They had considerable warlike knowledge. Near Elmira, which is close to the Pennsylvania boundary south of Seneca Lake, their ancient fortifications are still visible, having been located with the skill of a military engineer as a defense against attacks. Fort Hill at Auburn was also an Iroquois fortification that has yielded many relics, and other works constructed by them are shown in various places. The league carried on almost continuous warfare against the neighboring tribes and the frontier colonists, and were conspicuous in all the colonial wars. When in their greatest prosperity they numbered about fifteen thousand, and over ten thousand now exist, being located on Canadian reservations adjacent to the St. Lawrence River, and on eight reservations in New York, where there are about five thousand, in civilized life, chiefly engaged in agriculture. In the ancient league they were ruled by the Council of Sachems of the various tribes, the central council-fire being upon the shore of Onondaga Lake, and the Atotarho, or head sachem of the Onondagas, being chief of the league.
