 The fact that this division of the people of the same nation into tribes does not prevail generally among our Indian races favors the assertion of the Iroquois. On the other hand, the laws of descent, at least to the crown among the Aztecs, dimly shadows forth the existence of a similar social organization, which may have been reproduced among the Iroquois or preserved through a remote affinity of blood. At all events, it was the life and strength of the Iroquois League.
