The sudden attack of the Cave Beasts fell upon the Mammoth like lightning from a clear sky. In a moment he perceived his danger. Retreat was impossible before such active enemies; further advance equally so. Above and in front of him, crouched the Lion and Lioness while the Hyena and Cave Wolf hovered upon his flanks. The slightest misstep would have sent him tumbling down the slope. Finding himself unable to watch all of his enemies at once, he ignored the Wolf and Hyena and devoted his entire attention to the pair of big cats snarling and roaring above his head.

This left his rear entirely exposed. The Cave Wolf, a gaunt long-legged brute of almost bear-like size, now dashed in and attempted to seize the Mammoth’s hind leg. This move might have brought about Hairi’s undoing had it succeeded. A moment’s distraction,—a turn of the head would have exposed his neck and shoulder to the two furies in front. But the Wolf’s cunning strategy was met by the prompt action of one whom until this time the Cave Beasts had entirely ignored.

A squat, powerful figure suddenly darted from behind the Mammoth and faced the Cave Wolf with all teeth bared and eyes flashing like coals of fire from the bottom of two deep pits. It was Pic the Ape Boy, his face distorted with furious rage. Like a flash, he sprang between the Mammoth and Wolf and before the latter could close in, he had seized a jagged rock and raised it threateningly aloft. The huge Wolf snarled and gnashed his teeth, but he advanced no farther.

In spite of this diversion, the Mammoth was in a truly desperate plight. He seemed to have lost all power of resistance. The Hyena now sought to turn the scale by stealing around upon the Ape Boy from behind. The Mammoth observed and gave up all hope. Surrounded by enemies and unable to employ his great weight and strength to any advantage, he raised his head like one drowning and bellowed in his dire distress:

“Wulli! Help! Oh Wulli!”

From his refuge in the grotto, the Rhinoceros heard; and the call for aid changed the trend of his thoughts like magic. Hairi, his partner, was being hard pressed by a horde of Cave Beasts seeking to destroy him. In an instant, all enmity for the Mammoth fled from his breast. He proceeded to act. With a bound, he cleared the grotto and bore down upon the Cave Beasts in a furious charge, thundering, roaring, squealing, tail straight out behind and the fire of battle in his eyes.

All heard, saw and felt him coming. The Mammoth groaned as he espied the strange figure—supposedly some new enemy—speeding across the ledge; then his heart gave a great leap as Wulli completed his meteoric dash and halted on the edge of the terrace with a jolt that shook the rock.

His dramatic arrival threw consternation into the ranks of the Cave Beasts. The Hyena fled in terror and the Wolf raced down the slope lickety-split with his tail between his legs. Grun Waugh growled angrily at the sudden turn of affairs. As he crouched with tail lashing from side to side, the eyes of the Rhinoceros fell upon him. Wulli uttered a shrill squeal and charged with the swiftness of thought. The Cave Lion took one look at the oncoming horn and waited to see no more. With a blood-curdling screech, he sped along the ledge like a streak of yellow light with the Rhinoceros at his heels. For an instant it seemed as though he must surely be impaled upon the horn threatening his rear. The fear of such a catastrophe lent him wings. A fresh burst of speed and his lead was increased to a more comfortable margin. All his dignity was cast aside in a frantic effort to put the greatest possible space between his hindquarters and the Rhino’s horn. He reached the edge of the terrace and shot down the slope never stopping until all possibility of his being overtaken was beyond the shadow of a doubt.

On seeing the uselessness of further pursuit, Wulli came to a sudden halt. A sedge-tuft protruding from a crevice, chanced to catch his eye and he proceeded to nibble it with an air of the utmost unconcern. The battle was over.

The Mammoth now mounted the terrace followed by the Ape Boy. Both gazed at the Rhinoceros in amazement.

“Owk, owk; wonderful!” the big Elephant bellowed. “Never have I seen anything more wonderful than the way you made Grun Waugh run.”

Wulli said nothing. With most becoming modesty, he continued to bite at the tuft before him; but he was thinking. In his mind, glowed the spark of an almost forgotten purpose; of wrongs unavenged, as he watched his partner out of one eye. Then with brows contracted and nostrils swelling ominously, he turned and advanced upon the Mammoth.

Hairi sensed the approaching storm. His trained eye noted the lowered horn and his partner’s determined air. He became confused and stood staring like one in a trance, too helpless to move.

Slowly the Rhinoceros advanced until his horn was almost beneath the Mammoth’s chest. One quick upward thrust and the affair would be quickly ended. He paused and Hairi awaited the fatal stroke, his limbs paralyzed with horror.

Suddenly a dark figure sprang between the pair. It was the Ape Boy. His body almost touched the tip of Wulli’s horn.

“Back, pig-beast,” he howled. “Would you dare touch the Mammoth? You have gone mad.”

The Rhinoceros raised his head and retreated a step. The amazement, now shown in every line of his face, was a picture to see.

“You?” he gasped and choked.

“Yes, I.”

“Can you; will you fight?” the Rhinoceros demanded eagerly.

“I can and will. You shall see.”

“Good,” Wulli grunted. “When you are ready, begin.”

“But I have no weapon,” said the Ape Boy. “You have a horn; I nothing. Will you fight fair?”

The Rhinoceros nodded. The youth was making for the grotto when Wulli stopped him.

“That red beast with the hot breath?” he grumbled. “No; you must fight with something else. I have had enough of its bad smell.”

“I will fight you with ax and dart,” replied the other angrily. “They lie on the cave-floor. Are you afraid?”

Wulli stepped back. Pic entered the grotto and reappeared in a moment bearing in his right hand a flint ax-head bound in a stout wooden haft. Several darts tipped with sharp-pointed flakes were in his left. Such were the Ape Boy’s weapons—the stone-ax and short stabbing spear—and not to be despised when a bold heart and powerful arm were behind them.

He laid the darts on the rock platform and took a position upon the edge of the terrace with ax swung over his right shoulder.

“I am ready; now begin,” and he waited for the Rhinoceros to attack.

Wulli aroused himself with a start. This was to be a duel to the death—no light affair,—touch, scratch and both satisfied. Rarely did he so bungle in his work. He lowered his horn, squared his legs and then found himself unable to proceed. That Ape Boy was so deadly calm and looked at him so strangely out of his deep-set eyes. Wulli felt sobered, awed. He would have welcomed violence; but those eyes chilled his marrow. He made one last effort to lash himself into a frenzy but it was no use. His eyes sought the ground; his tail hung limp like a wet string.

“Umph,” he grunted; “I will not fight one who must stay on the ground because somebody has pulled off his tail.”

Pic’s eyes opened wide.

“Who says that?” he growled in a hoarse voice.

“Grun Waugh—and I say it because it makes you angry. ‘Once you had a tail and jumped about in the trees;’ he said that too.”

Pic was fast losing his temper, a fact which now put the Rhinoceros in the best of humor.

“Ape-beast hiding in a man’s skin,” he sniffed. “The Lioness said that.”

“Agh! What more?” The Ape Boy’s eyes blazed.

“Umph,” grunted Wulli. “Ask Grun Waugh. He and his pack have gone to the grotto of Sha Pall. The Wolf told him of a lone man who lived there.”

“A lone man? Whoow! Hardly a fair match is four cave-beasts against one lone man.” Pic’s rage softened as he thought of a fellow-being set upon by such overwhelming odds.

“A poor match indeed,” Wulli admitted. “He was sick too—the Man was. The Wolf said so.”

“Sick and alone?”

“Yes and he was blind in one eye. I heard the Wolf say that too.”

“What—blind?” Pic gripped his ax-handle until the wood creaked. “What more did the Wolf say?”

“Nothing more,” Wulli replied. “But the Hyena seemed to know who the man was—an old man with grey hair; a leader of other men. He was asking Grim Waugh’s leave to go and visit the grotto of Sha Pell and pay his respects to the lone man who was old, sick and blind in——”

“Agh, ar-rr-ah-h!” With a hair-raising yell the Ape Boy fairly hurled himself from the ledge and shot down the slope leading to the valley. The Mammoth and Rhinoceros stood motionless, speechless with amazement as they watched the flying figure grow smaller and smaller and finally disappear among the clefts and boulders far below.
