Indian Treaties

I am surrounded by books and I found what I was looking for, at least a little of it. This book was in the stacks: Treaties between the United States and the Indian tribes / edited by Richard Peters. [Boston : Charles C. Little and James Brown, 1846] There is a treaty with the Chayenne Indians that was recorded in 1825. I need to find out what land was allotted to the Chayenne Indians in 1825. This treaty basically stated that the Indians acknowledge that they are living in the United States territory "they reside within the territorial limits of the United States, acknowledge their supremacy, and claim their protection," and will not wage war. They also agree that the conduct of one individual acting alone will not cause the government to hold the tribe responsible. Excuse me if I am using older language or terms but I am reading about the people our government was referring to in 1825, and the spelling has changed. Also the term Native Americans is actually more correct to use.
Could this treaty be found online? Maybe. Yes, there it is on www.firstpeople.us
Amazing this world we live in today. And complicated. The spelling on the website is "Cheyenne." Treaty with the Cheyenne tribe July 6, 1825

Now I just found another treaty with the Arapaho and Cheyenne February 15, 1861, and Little Wolf is a representative of the Cheyenne with others. We will see what has been promised.
