DENVER CITY, Wednesday, Sept. 28.
    Maj. WYNCOOP, of the First Colorado Cavalry, has arrived from Fort Lyon with seven of the principal chiefs of the Cheyenne Arapahoes, and four white prisoners delivered up by them, viz: LAURA ROPER, ISABELLA UBANKS and AMBROSE ASHLEY, all captured near Oak Grove, Kansas, and DAN MARBLE, taken from the train near Plum Creek. All of them are children except Miss ROPER, a young lady of about 18. The Indians still held Mrs. UBANKS, Mrs. MARBLE and child, but promised to give them up. These chiefs come here to make a treaty with Gov. EVANS, and offer to send their warriors with the white troops to fight the Kiowas and Comanches. The scarcity of food and prospect of a hard Winter, it is thought, compel them to this step.
