The boys hunted for her in all imaginable places on the ranche where they thought she might possibly be, but could not find her. When Joe and Rob returned from their fruitless quest, the family were too thoroughly frightened to think of eating. Mr. Thompson mounted his horse and started to make the rounds of the nearest neighbors to learn whether she was visiting any of them.

He returned to the ranche long after dark, but brought no news of her whereabouts, and found every member of the family in tears, and his wife nearly crazy. He was told that Kate's pony had come home, riderless, to the corral while he was absent, and a small sumac bush to which his reins were tied, had been torn up by the roots and was dragging at his feet. None of them could conjecture where she could be.

"My God!" exclaimed her mother, "if the Indians have captured her and carried her off, what shall we do?"

"Something must be done at once," said Mr. Thompson. "Joe, get your pony quickly, and we will hurry to the fort to learn whether any Indians have been seen or heard of in this vicinity to-day. If so, we will get the commanding officer to send out a squad of soldiers immediately. You must go with them, Joe, and trail the savages if you can find any signs of them."

Joe and his father rode as rapidly to Fort Harker as their animals could carry them; went to the commanding officer's private quarters, as the business offices were closed after night, and reported to him the terrible anguish which the family were suffering.

They immediately adjourned to the Adjutant's office, and the commander sent his orderly for the officer of the day. When he made his appearance, he asked him whether any reports had been received concerning Indians being in the vicinity. He replied that no such report had been received by him, and it was his belief that none of the hostile savages were in the immediate country.

At that moment, Buffalo Bill entered the room. He was chief of scouts at Fort Harker, and had just returned from some perilous mission to one of the military posts on the Arkansas, and was coming from the stable, to report to the Adjutant. He was told of the mysterious disappearance of Mr. Thompson's daughter Kate, and the opinion of the famous Indian fighter and courier was asked as to what he thought of the matter, as no Indians had been reported in the vicinity.

"Well," said Bill, "because you gentlemen have received no report of the savages, it does not follow that none have been here. I know that they have been here, and to-day. As I crossed Bluff Creek on my way here this afternoon, about six o'clock, I saw in the distance a band of Indians, numbering about ten or twelve, riding rapidly south. I hid myself in a ravine so that they should not discover me, but I got a good look at 'em with my field-glass. I think they were Comanches, though I can't be certain of that; they might have been Cheyennes or Kiowas; they were too far off to be made out exactly. Now, you ask for my opinion as to what has become of the gentleman's daughter. I believe those Indians have her; because they were riding so fast toward their villages, and they are, you know, all south of the Canadian.

"But don't let Mr. Thompson worry too much; the simple fact that she is a prisoner among them is bad enough. If among the Kiowas, and the chief, Kicking Bird, is in the village when the band arrives with the girl, he will not allow her to be harmed. He is a cunning old fellow, and knows the value of money. He will have good care taken of her, and get a heavy reward from the Government for ransom. If she should fall into the village of Sa-tan-ta, God help her! He is the worst demon on the trail; but anyhow, I don't think they will harm her, as they will want a ransom."

"Well," said the officer, "I am sorry that I have no cavalry at the post, but I will send a detachment of the infantry after them in six-mule wagons. I imagine it will be a useless task to try to catch up with them if, as Buffalo Bill says, they were going as fast as they could to their village on the Canadian. Lieutenant Hale," said he, turning to the Adjutant, "make a detail at once of thirty men, and send them out under a couple of non-commissioned officers on the trail of the savages, if it can be found. Anyhow, some sign may be discovered that will tell us whether the girl is with them."
