Major S. G. Colley,

                             Sir
    I have received your letter of the 4^th instant informing me of the arrival of three Indians at Fort Lyon with a letter from "Black Kettle" proposing peace, and enclosing a copy of the same.
    I have learned unofficially that Major Wynkoop has started with a party of Soldiers to proceed to the camp from which these Indians came and I do not deem it advisable to take any steps in the matter until I hear the results of his expedition.
                                                           Very Respectfully,
                                                           Your obt servt,
                                                           Jno. Evans,
                                                 Gov & Supt Ind Affairs.
