It has been said more than once that the Indians along the western bank of the Mississippi were less aggressive than those who so often crimsoned the soil of Kentucky and Ohio with the blood of the pioneers. Such was the truth, but those who were found on the very outermost fringe of civilization, from far up toward the headwaters of the Yellowstone down to the Gulf, were anything but harmless creatures. As the more warlike tribes in the East were pushed over into that region, they carried their vindictive natures with them, and the reader knows too well the history of the great West to require anything further to be said in that direction.
