you are tired! But remember, you've got to carry me back," he added, grimly.
Soon the ranch house and the corral were mere specks in the distance, and then even these faded from view. The pony kept to the open country, and not once did he slacken his speed.
"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.
