With whoops of despair some threw themselves over the cliff. Others rushed into the cave, while some climbed up the rocky walls at either side. A few remained, firing down at the attackers below.

Rosemary's yells, and those of her brother, carried to the soldiers and cowboys. At first they thought a sally was about to take place.

But when they saw some Indians come over the wall, one luckless imp slipping and falling to his death, some idea of what was taking place became manifest to Captain Marshall.

"They're in a panic!" he cried. "Something has frightened 'em! Come on, men!"

He led a rush forward, just as Rosemary appeared at the top of the wall, waving her neck handkerchief in a frenzied signal.

"There she is! Rosemary!" cried Bud, not exactly recognizing his cousin, but guessing the girl could be none other.

The rush of the attackers, together with the panic that had run through the ranks of the Indians like wildfire, was all that was needed to turn the scale. The Yaquis, with howls of fear, not knowing what it was all about, threw down their guns and sought for means of escape.

Mike, the leader, seemed dazed at the suddenness of it all. But he gathered his wits together and, seeing Rosemary at the wall, waving to the soldiers and cowboys below, the desperate Yaquis sprang toward her.

But Floyd was watching his sister. The lad picked up a revolver from where it had fallen as its owner retreated and fired point blank at Mike. The ruffian crumpled up and went down in a heap, as Rosemary herself, unable to stand the strain longer, sank down half fainting.

Her ruse had succeeded. The Yaquis were on the run.
