"And I believe he has more than twenty-five head with him," said Mr. Kelley, who dropped everything and came to Stanley's side. "He's got fifty if he's got one. Boys, I guess you had better go out there. They are tired most to death, and we might let them come in and get some supper."

Although the two cowboys had ridden all of fifty miles that day, there was no objection raised to this arrangement. Without saying a word they buckled on their belts containing their revolvers, shouldered their saddles and bridles, and went out behind the hay racks. When they came within sight a few minutes later, they were going at full speed to meet their employer and his cattle.

"Now, maybe you are able to see something off there, but I can't," said Tom, after he had run his eyes in vain over the horizon. "I can't see a single thing."

"Can't you see that long line that looks like a pencil-mark off there?" said Mr. Kelley, trying in vain to make Tom see the object at which he was looking. "Well, it's there plain enough. When you have been on the plains as long as I have, you'll notice all little objects like that one, and, furthermore, you will want to know what makes them. It will be two hours before they come up, and you sit down here on the bench and watch it. I will go down and get some supper."

Tom seated himself on the bench beside the door and tried hard to make out the approaching line of cattle, but could not do it. Finally he was called to supper, and went down saying that he would give his eyes a little rest and then maybe he could see them; but he couldn't do it now.

"Supposing you were in a line of march and had a scout out there where those men are, and he should begin riding in a circle, what would you say?" asked Mr. Kelley.

"I wouldn't say anything," exclaimed Tom. "I wouldn't know what he meant."

"He would mean that there was danger close at hand, and you had better be gathering your cattle up," said Mr. Kelley. "And if they were scattered as far apart as those cattle are, you would want a small battalion of men to answer your orders."

"What would be the danger?"

"From Cheyennes, of course."
