"I guess he'll drop into a walk when his wind is gone," thought Dave. But the pony's breathing apparatus showed no sign of giving out. Dave allowed his eyes to turn back, and calculated he had gone two or three miles. "Maybe we had better turn back now," he murmured, and tried to guide the steed in a circle. But this was a failure. The pony kept straight ahead, running due eastward, as the youth could see by the sun.

"All right, go as far as you please," said Dave, grimly. "If you can stand it, so can I," and he settled in the saddle.

Another two miles were covered, and then the bronco commenced to slacken his speed. Dave was on guard at this, and it was well to be, for, a second later, the pony once more tried the trick of flinging his rider over his head. But the effort was a failure, and in return Dave dug his knees deeply into the steed's ribs. Then off went the pony on a run again.

This time the bronco did not cover over a mile before dropping into a walk. Then Dave tried again to turn the animal, but without success.

"Don't want to go back, eh?" said the youth. "Well, you've got to, and that is all there is to it!" And he hit the pony a sharp slap on the neck and dug his knees into the animal's ribs as before.

The bronco was now losing courage. He commenced to run, but did not keep it up for more than a hundred yards. But when he dropped into a walk, Dave urged him up, and again he ran, but now only a dozen steps. Then the youth pulled on the left rein, and the bronco came around with scarcely any trouble.

"You aren't mastered yet, but you're pretty close to it," said the boy. "We are going home, understand, home!"

The bronco moved forward about a hundred feet. Then he deliberately dropped on the prairie and lay on his side, as quiet as a lamb.

"Want to rest, eh?" said Dave. "Well, not out here. You brought me here and you've got to take me back. Get up!"

He gave the animal a prod in the side. The bronco kicked out. Then Dave gave a harder prod. This the pony would not stand, and up he came with surprising agility. He tried to bolt, but Dave caught the saddle and clung there. They headed again eastward, away from the ranch.
