CHAPTER XV.
MORE TREACHERY.
When Frank awoke, it was nearly dark.

The glade was lighted up by a fire, that one of the Rancheros had kindled, and beside which he stood, superintending the cooking of the supper.

Archie and Johnny were still sleeping soundly, but Arthur Vane's blanket was empty, and that young gentleman was nowhere to be seen.
Frank raised himself to a sitting posture, rubbed his eyes, and yawned; and then, seeing that the cook was rummaging in the pack-saddle after more luxuries, and judging by that that supper was nearly ready, he shook his companions, and arose to his feet.

He went to the spring, and was preparing to wash his hands and face in the little brook that ran across the glade, when his attention was attracted by the sound of voices close by.

He found that they came from behind the bowlder; and, after listening a moment, he recognized the voices as those of Pierre Costello, and Arthur Vane.
