All this time Whirlwind stood calmly watching the performance. It is reasonable to believe he was interested, and had he possessed the power of laughter he would have thrown back his head and "cracked his sides" at the sight. What a pity that George and Victor Shelton could not have peeped out from some concealment. They would have remembered the picture all their lives.

Only by this grotesque exercise could the young Shawanoe find vent for his overflowing spirits. There is nothing in all the world that can take the place of physical vigor and health—a truth which unnumbered thousands do not realize until too late. Temperance, right living, obedience to the laws of hygiene, and a clear conscience, never fail to bring their reward and to give to this life a foretaste of the blessed one to come.

Deerfoot had chosen an open space, walled in by rocks, boulders and stunted undergrowth for his physical outburst. When the performance had gone on for some time, he danced up to the side of Whirlwind and planted one of his feet against his ribs so sharply that the stallion was forced back for a step. Instantly he wheeled, partly reared and struck at his insulter, but he was so afraid of hitting him that the blow was awkward and missed the Shawanoe by a goodly distance. As he dropped on his feet, Deerfoot darted under his belly and repeated the blow from the other side. The white teeth of the steed snapped within a few inches of the shoulder of the youth, who slapped the nose before it could be withdrawn.

Whirlwind wheeled to face his master, who landed lightly on his back and pounded his sides with his heels. The contest recalled that other struggle between the two, months before on the prairie, when it was a battle royal indeed. But the great difference lay in the fact that the present one was good-natured on both sides, and it is easy to believe that the stallion wished the youth to prove himself once again his master. An intelligent animal loves to obey him who has proved his superiority.

There is no telling all that was done by the Shawanoe. He sharply pinched the glossy hide. He griped the nostrils of the steed as if to shut off his breath, but was too considerate to continue this long, since the horse seems unable to breathe through his mouth. He placed his hand and forearm over the eyes of Whirlwind as if he meant to play blind-man's buff with him. He yanked the forelock and reproached him as being of no account.

The stallion did his part in the way of defense and retaliation, but he was continually handicapped by his dread of hurting his master. And yet it would seem that, recalling that other conflict, he ought to have had no such apprehension, for he had done his best on that occasion to kill the Indian youth, who was not harmed at all, and overcame the creature that possessed ten times his strength.

Whirlwind showed signs of fatigue before Deerfoot did. A comparatively clear path stretched in front. Dropping from the back of the horse, the Shawanoe challenged him to a race. Bounding off at his highest bent, the youth dashed across the country with the speed of the wind. He ran as he did when on the second half of his race with Ralph Genther.

Ah, Whirlwind had him now! No danger of hurting his audacious master, except so far as his feelings were concerned, and the stallion did not spare them. Despite the favorable ground, more than one boulder or bunch of matted undergrowth had to be leaped, and the two went over them like a couple of flying birds. But the steed steadily drew away from the fleet Shawanoe, who at the end of two or three hundred yards, finding himself hopelessly to the rear, gave up.

"Deerfoot is only a child when he races with Whirlwind; have mercy on him."

Hearing his call, the steed ceased his running, wheeled about and waited for his master to come up. Deerfoot patted him affectionately and vaulted upon his back, happy as he could be over the triumph of his matchless animal that was as well pleased as he.
