While more than a hundred yards still separated the combatants the Sioux horseman wheeled to the right, and, without checking his speed, started to describe a long circle around the youth. The latter spoke softly to Jack, who slowly turned, so as to keep his head continually pointed toward the enemy. Evidently the animal understood the situation, and was competent to do his part.
The Sioux at the base of the ridge had given over their effort for the time to capture their ponies. All their attention was centred on the two horsemen out on the prairie.
As yet the Indian made no move to fire. Warren was looking for him to throw himself over the side of his animal, and aim from under his neck, screening his own body meanwhile from the bullet of the young rancher. Instead of doing so, however, he described a complete circle about Warren, coming back to his starting point, while Jack continued to move around, as if on a pivot, keeping his head always facing his foe.
The warrior was starting on his second round, when, without any perceptible movement, he discharged his gun. Warren saw the blue puff of smoke, the report sounding dull and far away in the wintry air.
The bullet did not pass nigh enough for him to be aware how close it was. It would seem that the Indian ought to have done better, for it was noticeable from where Warren sat that in completing his circle he had shortened it, and was now several rods nearer than when he set out to circumnavigate him.
"It is no more than fair to return the compliment," thought Warren, raising his Winchester, taking careful aim, and pulling the trigger. Truth compels us to say, however, that his shot went as wide of the mark as the one aimed at him. Thus far honors were equal between them.
The Sioux continued his trip around the central object, though what he expected or hoped to accomplish by this curious proceeding was more than his antagonist could conjecture.
The advantage during the performance possibly was with young Starr; for, by keeping the nose of Jack pointed toward the other he offered the least possible target to the foe, while the course of the Indian compelled him to hold his pony broadside, himself remaining a conspicuous object on his back.
"I think I can shorten this business," reflected Starr, "by another shot or two. I am standing still, and if I can't bring that fellow off his horse I'm of little account."
But the Sioux was more watchful than he suspected. Hardly was the Winchester raised when, presto! the warrior disappeared. He had flung himself far on the other side of his pony, and was capable of maintaining that situation while making the circuit of the youth.
