Read the quote. I am Dekanawidah [identified as the traditional founder of the Iroquois Confederacy] and with the Five Nations confederate [united for a common purpose] lords I plant the Tree of the Great Peace. . . . Under the shade of this Tree of the Great Peace we spread the soft white feathery down of the globe thistle as seats for you Adodarhoh [an Onondaga chief], and your cousin lords. . . . There shall you sit and watch the council fire of the confederacy of the Five Nations, and all the affairs of the Five Nations shall be transacted at this place before you. . . .

We place at the top of the Tree of the Long Leaves an eagle who is able to see afar. If he sees in the distance any evil approaching or any danger threatening he will at once warn the people of the confederacy. The smoke of the confederate council fire shall ever ascend and pierce the sky so that other nations who may be allies may see the council fire of the Great Peace . . .
