EDITORS NEWS:--I want to gvie [sic] you notice that if you don't stop calling my people "red devils," "thieving scoundrels," "women violators," "children scalpers," &c., &c., I will send Col. Tappan to "investigate" you. We are and always have been "friendly" as a people. We have some bad boys, just like white folks whom we cannot control--some of them fired into Capt Tyler's train the other day; they tried to kill his squaw and pappooses, for what he did to us last year--some of them burned the Wisconsin Ranche--and have been burning trains "and sich," but we are friendly. You see by calling us such names, the soldiers are likely to come on us and repeat "Sand Creek," and then where will you be. All these epithets you bestow on us will go back home to roost. We have Tappan and Wyncoop, and Gen. Sanborn, and the Committee on the Conduct of the War, and Bennett, and Bradford, and Henry Leach, and Gen. Slough, and his paid organ, (the Atchison Champion,) all on our side, besides a host of others, don't you see! Now you have altogether "too much acrimony." We are "intelligent, sensible people;" and very friendly. You had better keep still.             Truly yours,
                                                                                        BLACK KETTLE.
