“God! If they once get in there, we're gone!” cried Allan. “We're cut off from everything. Our animals will be slaughtered. The boy will die! They can bombard us with rocks from aloft. It means annihilation!”

Already he was running up the path toward the palisade. Not one second was to be lost. There was no time even to call a single man of the Folk to reenforce him. Single-handed and alone he must meet the invaders' first attack.

Panting, sweating, stumbling, he scrambled up the steep terrace. And as he ran his thoughts outdistanced him.

“Fool that I was to have left the bridge!” choked he. “My first act when I set foot on solid land should have been to cut the ropes and drop the whole thing into the rapids! I might have known this would happen--fool that I was!”

The safety, the life, of the whole colony, including his wife and son, now depended solely on his reaching the southern end of the bridge before the vanguard of the Horde.

With a heart-racking burst of energy he sprang to the defence, and as he ran he drew his hunting-knife.

Reeling with exhaustion, spent, winded, yet still in desperation struggling onward, he won the top of the cliff, swung to the left along the path that led to the bridge, and--more dead than alive--rushed onward in a last, supreme effort.

Already he saw the Anthropoids were within a hundred feet of the abutment. He could plainly see their squat, hideous bodies, their hairy and pendent arms, and the ugly shuffle of their preposterous legs, as at their best speed they made for the cliff.

Three or four poisoned darts fell clicking on the stones about him. Howls and yells of rage burst from the file of beast-men.

One of the horrible creatures even--with apelike agility--sprang up into the guy ropes of the bridge, clung there, and discharged an arrow from its bamboo blow-gun, chattering with rage.
