Observing that the boy had no intention of giving way to them, the two cowboys held their course, their eyes fixed on the offending tenderfoot until finally only a few rods separated them.
Suddenly, both men pulled their mounts sharply to the right, and, digging in the spurs, plunged straight for Tad.
"So that's their game, is it?" thought the boy.
They were going to run him down.
Tad's eyes flashed indignantly, yet still he made no move to pull his pony out of the street.
"Keep off!" he shouted. "Don't you run me down!"
"W-h-o-o-o-p!" howled the pair, at the same time letting go a volley right under the hoofs of his pony. It seemed to the lad that the powder from their weapons had burned his face, so close had the guns been when they pulled the triggers.
Tad had braced himself for the shock that he knew was coming, gathering the reins tightly in his right hand and leaning slightly forward in his saddle.
They were fairly upon him now. Two revolvers exploded into the air, accompanied by the long shrill yell of the plainsmen. But just when it seemed that the lad must go down under the rush of beating hoofs, Tad all but lifted his pony from the ground, turned the little animal and headed him in the direction in which the wild horsemen were going.
The boy's clever horsemanship had saved him. Yet one of the racing cow ponies struck the boy and his horse a glancing blow. For the moment, Tad felt sure his left leg must have been broken. He imagined that he had heard it snap.
