f Indians
lined up, with their backs toward them, along the wall of the
improvised fort.

What Rosemary said she never really knew. It was a burst of wild,
hysterical yelling, such as girls and women alone are capable of. And
as she screamed and ran she pointed back toward the cave.

As for Floyd he declared that what he yelled was something like:

"They're coming! They're coming! They're attacking in the rear!"

To this he added some improvised warwhoops of his own devising, and
some football yells, for he had been a cheer leader at one time for his
college team.

Whatever was said little mattered. It was the character of the
shouting of the desperate youth and maiden, and their actions that
counted. Coming as Rosemary's ruse did, after the hardest firing yet
on the part of the attackers, it rather got on the nerves of the Yaquis
if they had such organs, which is doubtful.

To every one of them it appeared, as Rosemary and Floyd intended it
should, that an attack from the rear was about to take place. As
Rosemary had guessed, the Indians knew no more about the cave than she
did. They had hastily examined it and decided there was no rear
entrance or exit, as the case might be. But they might have overlooked
some hidden passage, and this is what all of them evidently thought had
been done.

At any rate, as Rosemary and Floyd rushed out, yelling almost like
Indians themselves, a panic started among the Yaquis. They saw
themselves caught between two fires, with no retreat possible.

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 Indi
