It was clear, also, that this was but a little scouting party which the renegade had led in to spy upon the weakness of the tribe. This was as far as he could premise with any certainty. The obvious conclusion was that these spies would return to their own country, to lead back such an invasion as should blot the Children of the Shining One out of existence.

Grôm was quick to realize that to listen any longer was to waste invaluable time. All that it was possible for him to learn, he had learned. Writhing softly back till he had gained what he considered a safe distance from the spies, he rose to his feet and ran, at first noiselessly, and crouching as he went, then at the top of that speed for which he was famous in the tribe. Reaching the Caves, he laid the matter hurriedly before the Chief, and within five minutes they were leading a dozen warriors up the trail.

Besides their customary weapons, both Grôm and the Chief carried fire-sticks, tubes of thick, green bark, tied round with a raw hide, filled with smouldering punk, and perforated with a number of holes toward the upper end. This was one of Grôm’s inventions, of proved efficacy against saber-tooth and bear. By cramming a handful of dry fiber and twigs into the mouth of the tube, and then whirling it around his head, he was able to obtain a sudden and most unexpected 129 burst of flame which no beast ever dared to face, and which never failed to compel the awe and wonder of his followers.

Like shadows the little band went gliding in single file through the thickets and under the drooping branches, their passage marked only by the occasional upspringing of a startled bird or the frightened crashing flight of some timorous beast surprised by their swift and noiseless approach. Arriving near the hollow under the ledge, they sank flat and wormed their way forward like weasels till they had gained the post of observation behind the vine-clad rock.

But the strangers had vanished. An examination of their footprints showed that they had fled in haste; and to Grôm’s chagrin it looked as if he had himself given them the alarm. The problem was solved in a few minutes by the discovery that Mawg––easily detected by his finer footprints––had scaled the ledge and come upon the place where Grôm had lain hidden to watch them. Seeing that they were discovered, and that their discoverer had evidently gone to arouse the tribe, they had realized that, the Bow-legs being slow runners, their only hope lay in instant flight. From the direction which they had taken it was evident that they were fleeing back to their own country.

The Chief ordered instant pursuit. To this Grôm demurred, not only because the fugitives had obtained such a start––as was shown by the state of the trail––but because he dreaded to leave the Caves so long unguarded. He foresaw the possibility of another band 130 of invaders surprising the Caves during the absence of this most efficient fighting force. But the Chief overruled him.

For several hours was the pursuit kept up; and from the trail it appeared, not only that Mawg was leading his followers cleverly, but also that the Bow-legs were making no mean speed. The pursuers were come by now to near the head of the valley, a region with which they were little familiar. It was a broken country and well fitted for ambuscade, where a lesser force, well posted and driven to bay, might well secure a deadly advantage. The tribe was too weak to risk its few fighting men in any uncertain contest; and the Chief, yielding slowly to Grôm’s arguments, was on the point of giving the order to turn back, when a harsh scream of terror from just ahead, beyond a shoulder of rock, brought the line to a halt.

Waving their followers into concealment on either side of the trail, the Chief and Grôm stole forward and peered cautiously around the turn.

Straight before them fell away a steep and rugged slope. Midway of the descent, with his back to a rock, crouched one of the Bow-legs, battling frantically with his club to keep off the attack of a pair of leopards. The man was kneeling upon one knee, with the other leg trailed awkwardly behind him. It seemed an altogether difficult and disadvantageous position in which to do battle.

“The fool!” said Bawr. “He doesn’t know how to fight a leopard.” 131
