Flatfoot was scandalized. He jumped back a few feet and glared at Waldo. Then he lowered his head and came at him once more with the very evident intention of rushing him off his feet by the very weight and impetuosity of his charge.

This time the sharp stick slipped quickly over the top of the hide-covered atrocity and pierced Flatfoot's neck just where it joined his thick skull.

Burying a foot of its point beneath the muscles of the shoulder, it brought a scream of pain and rage from the hairy beast.

Before Waldo could withdraw his weapon from the tough sinews, Flatfoot had straightened up with a sudden jerk that snapped the sword short, leaving but a short stub in his antagonist's hand.

Nadara had been watching the battle breathlessly, ready to flee should it turn against her champion, yet at the same time searching for an opportunity to aid him.

Like Flatfoot, the girl had never before seen spear or sword or shield in use, and while she marveled at the advantage which they gave Thandar, she became dubious as to the result of the encounter when she saw the sword broken, for the spear had been snapped into kindling-wood by Flatfoot when he tore it from his arm.

But Waldo still had his cudgel, fastened by a thong to his sword-belt, and as the cave man rushed upon him again he swung a mighty blow to the low, brutal forehead.

Momentarily stunned, the fellow reeled backward for a step, and again Waldo wielded his new weapon.

Flatfoot trembled, his knees smote together, he staggered drunkenly, and then, when Waldo looked to see him go down, the brute power that was in him, responding to nature's first law, sent him hurtling at the Bostonian's throat in the snarling, blind rage of the death-smitten beast.

Catapulted by all the enormous strength of his mighty muscles, the squat, bear-like animal bore Waldo to earth, and at the same instant each found the other's throat with sinewy, viselike fingers.
