"The Siouan Indians"
W. J. McGee
The land was already held by powerful Indian tribes and Confederacies, who waged war after war, of the most ferocious and bloody character, against the men of the border, in the effort to avert their inevitable doom, or at least to stem for the time being the invasion of the swelling tide of white settlement.
"Thomas Hart Benton"
Theodore Roosevelt
Do better still, allow them to form peculiar states and territories, preserving their languages and laws, and admit these states into your Confederacies.
"The American Nations, Vol. I."
