A cry of rage burst from Seymour.

They were standing upon a narrow ledge in the cliffs which formed the temple walls. Twenty feet below them was the den of Rahee, in which their friend was awaiting his doom. The sight of the devilish brute advancing upon the professor roused all the fury in their natures against the savage creatures who had delivered him to such a fate.

In a delirious rage, Seymour raised his rifle. Another instant and Rahee the terrible would have been no more; but, ere the baronet could fire, Silas gripped his arm.

“Don’t plug the brute,” he cried sharply, “it’s the only thing that’ll keep those fiends back when they tumble to our game. I’m goin’ down.”

Ere Seymour could restrain him, Silas had laid down his rifle, swung himself over the edge, and, with a cheery shout to Mervyn, commenced the descent. From ledge to ledge the wiry American descended, as cool and collected as though it were an everyday matter for him to venture into the den of a giant spider. A hoarse roar of rage rolled up from the assembled wolf-men as they became aware of the Yankee’s daring move; but Nordhu looked on calmly, confident that Rahee would destroy rescuer as well as prisoner, which event would have well satisfied the murderous lust of the priest.

But it was not to be!

Rahee had paused in his spring as he saw this new development, seemingly startled by the barefaced audacity of the intruder. Doubtless it was the first time that any had entered his den voluntarily.

His pause gave the American just the interval he needed to carry out his plan. Descending the last few feet with a jump, he rushed between the monstrous spider and his victim. Quickly he forced a link of the chain which bound the scientist’s wrists with his sheath-knife, then pushed his friend sharply aside.

“Flicker,” he cried, “for your very life. I’ll keep this brute in check.”

With his heart beating madly against his ribs, the professor bounded across the rocky floor, and, never even pausing to remove the gag from about his mouth, commenced the ascent of the cliff.
