Copied from Annals of Wyoming, vol. 26, pg 76.  Excerpt from Brigham Young, Supt. of Indian Affiars, to Luke Lea, Commissioner of INdian Affairs, dated Great Salt Lake City, May 28, 1852.

It is not safe to trust too far the savage Indians notwithstanding all their professions of friendship.  Hence the impropriety of extending settlements faster than can be maintained; for our experience proves to us that although the whites, at their most earnest solicitation, may locate upon their lands with every assurance and safety and protection for themselves and property, yet when coming into daily contact with them, and stock begins to fill the range, their indolent and predatory habits lead them to incur the risk of satisfying their wants.  They also sometimes become saucy and offensive to females who are left without sufficient protection, but in most cases if their wants for food, and clothing are supplied, but little difficulty occurs. 

We have had some serious difficulties at various times with them, but it has been caused usually through these sources, as the people have been unable to furnish them with all they wanted; their involuntary contributions become too burdensome and when withheld exasperation ensued.  But chastisement when so richly deserved has had a most salutary effect, and in all instances with the exception of some Cumembahs; the hostile belligerents have come to terms and subsequently lived in peace with seemingly a better understanding than before.

These Cumembahs inhabiting principally the central part of this Territory extending north and south and westerly from the settlements and bordering upon the Desert as related in my former report of Sept 13/51 have as yet never come under the influence of a settlement of whites; but in Tooele and other places made such inroads upon the settlements, which altho’ in their vicinity were yet upon other Indian’s lands, as to compel the citizens in order to ensure their own safety to repel them and seek to break up their haunts by force.  These are the Indians that so infest Mary’s river.  It was supposed that some Panaks and Shoshonees attracted thither by their success in plunder had joined them; but a small representation from those tribes inhabiting in the vicinity of Fort Hall with whom I conversed a few days since, strenuously deny that either of their tribes or any part of them have ever gone there, and they seem totally ignorant of the fact if any such existed; although they admitted that they heard rumours of emigrants being robbed and killed upon that river.
