We had left the trail, and were pounding over the sage-brush desert. I could smell the sage, strongly pungent, and the alkaline dust began to irritate my throat; the sun, if one stood still, was strong enough to blister the skin of the hands.

For three-quarters of an hour it seemed to me that the distance between us and our quarry remained constant; but Dumble said we were falling behind. The thief was lighter than any of us, and his horse was evidently a stayer. The hills rose out of the haze, bleak and bare, seamed with gulches, a safe sanctuary for all wild things.

"If the cuss was within range, I'd try a shot," said the old man.

"I'd like to make out who he is," said Ajax.

Suddenly the horse of the thief fell. We discovered later that the beast had plunged into a piece of ground honeycombed with squirrel- holes. The man staggered to his feet; the horse struggled where he fell, but did not rise. His shoulder was broken.

"We have him!" yelled Dumble.

"Yes; we have him," repeated my brother. "Suppose we take a look at him?"

The thief had abandoned all idea of escape. He stood beside his horse, waiting for us; but at the distance we could not determine whether he intended to surrender quietly or to fight. Ajax adjusted his glasses, and glanced through them. Then, with an exclamation, he handed them to me.

"Kin ye make him out, boys?" asked our neighbour.

"Yes," said I, giving back the glasses to Ajax. He handed them in silence to old man Dumble. Then, instinctively, both our right hands went to our belts. We were not quite sure what a father might do.
