"Now, Chief Big Foot, you will never carry out the plan Chief Red Hatchet has decided upon, for the avengers of the brave Custer are hot on your trail."

Soon after the soldiers came in sight, and then Kit Carey hailed:

"Ho, the Seventh Cavalry!"

Instantly a halt was ordered, carbines clicked, and a stern order came:

"Advance and report yourself, sir!"

To the surprise of the advance guard three horsemen rode forward in the darkness, who appeared to be Indians.

"I am Lieutenant Carey of the Seventh, in disguise, and desire to see Colonel Forsythe," was the startling response of the supposed Indian chief, as he rode forward toward his regiment.

The men could hardly be kept from cheering when the gallant Carey appeared in the disguise of an Indian chief, for it told them that he had just come from some daring venture, for which he was famous.

"Ah! Carey, it is you in the guise of a Sioux chief?" cried Captain Wallace of K troop, riding forward and grasping his hand. "It is dangerous work for you, Lieutenant Carey, to ride upon the Seventh Cavalry rigged out as a Sioux chief in full war-paint."

"I joined the Sioux, Captain Wallace, to learn what Big Foot and his band were up to, and I have news for Colonel Forsythe," was Kit Carey's response.
