Bridge rose to his feet.  He buckled his cartridge belt about his waist and picked up his carbine, then he crawled under the rear wall of his tent and walked slowly off in the direction of the picket line where the horses were tethered.

“Ah, Senor Bridge,” said a pleasant voice in his ear; “where to?”

Bridge turned quickly to look into the smiling, evil face of Rozales.

“Oh,” he replied, “I’m going out to see if I can’t find some shooting.  It’s awfully dull sitting around here doing nothing.”

“Si, senor,” agreed Rozales; “I, too, find it so.  Let us go together—­I know where the shooting is best.”

“I don’t doubt it,” thought Bridge; “probably in the back;” but aloud he said:  “Certainly, that will be fine,” for he guessed that Rozales had been set to watch his movements and prevent his escape, and, perchance, to be the sole witness of some unhappy event which should carry Senor Bridge to the arms of his fathers.

Rozales called a soldier to saddle and bridle their horses and shortly after the two were riding abreast down the trail out of the hills.  Where it was necessary that they ride in single file Bridge was careful to see that Rozales rode ahead, and the Mexican graciously permitted the American to fall behind.

If he was inspired by any other motive than simple espionage he was evidently content to bide his time until chance gave him the opening he desired, and it was equally evident that he felt as safe in front of the American as behind him.

At a point where a ravine down which they had ridden debauched upon a mesa Rozales suggested that they ride to the north, which was not at all the direction in which Bridge intended going.  The American demurred.

“But there is no shooting down in the valley,” urged Rozales.

“I think there will be,” was Bridge’s enigmatical reply, and then, with a sudden exclamation of surprise he pointed over Rozales’ shoulder.  “What’s that?” he cried in a voice tense with excitement.

The Mexican turned his head quickly in the direction Bridge’s index finger indicated.

“I see nothing,” said Rozales, after a moment.

“You do now, though,” replied Bridge, and as the Mexican’s eyes returned in the direction of his companion he was forced to admit that he did see something—­the dismal, hollow eye of a six-shooter looking him straight in the face.

“Senor Bridge!” exclaimed Rozales.  “What are you doing?  What do you mean?”

“I mean,” said Bridge, “that if you are at all solicitous of your health you’ll climb down off that pony, not forgetting to keep your hands above your head when you reach the ground.  Now climb!”

Rozales dismounted.

“Turn your back toward me,” commanded the American, and when the other had obeyed him, Bridge dismounted and removed the man’s weapons from his belt.  “Now you may go, Rozales,” he said, “and should you ever have an American in your power again remember that I spared your life when I might easily have taken it—­when it would have been infinitely safer for me to have done it.”
