Ru's ascension to leadership was followed by six or eight days of intensive activity, during which the cave buzzed with excitement.

First of all, Ru solved the food problem by showing the people the secluded cave entrance which he had found; and through this, unobserved by the beast-men, they passed daily into the woods, returning always with roots and nuts enough to ward off immediate starvation. Meanwhile Ru labored assiduously at the construction of bows and arrows, which he made in an isolated little nook of the cavern, while Yonyo kept watch to see that no tribesman approached. And several hours each day he devoted to training the chosen ten in the use of the "wonder stick." He found not only that he had eager and imitative and hence capable pupils, but that his own skill vastly improved with practice, so that he was soon able to direct an arrow with accuracy to almost any desired spot. This art his followers, likewise, were not slow in acquiring, and he knew that the time for the encounter with the beast-men could not be far off.

The interval between the burial of Grumgra and the battle of the "wonder stick" was marked by two important events. To begin with, there was the disappearance of Wuff. The young wolf, who had been growing manifestly restive of late and at times distinctly ill-tempered even toward his master, at last found the summons of his kind to be stronger than the appeal of human companionship. Standing with Ru one evening near the rear cave entrance, he started forward with sudden alertness and with wildly gleaming eyes as a long-drawn, doleful call sounded from far away out of the twilight. The next moment he had answered that call in high-pitched notes of his own—and then suddenly he vanished. Ru waited for a while, whistling softly to the animal, but Wuff did not come back; nor did he come back on the next day, nor on the day that followed. And Ru sighed regretfully, and realized that he had lost a friend.

The second event was of a more personal nature. It concerned his courtship of Yonyo—and its successful culmination. Standing proudly before the tribe in Grumgra's old place beside the fire, he announced one evening: "Yonyo the Smiling-Eyed is my woman. Is it not so, Yonyo?"

Yonyo came sedately forward, and admitted that it was so—and there was no one who had anything more to say, although Woonoo the Hot-Blooded and Kuff the Bear-Hunter did scowl furiously and mutter angrily under their breath. Ru, however, did not heed them, but proceeded forthwith to perform a little ceremony which the tradition of the tribe made necessary. Taking a sharp bit of flint, he cut a sudden gash in Yonyo's left arm; then, while the blood gushed forth and she bit her lip to keep back a groan, he made a similar wound in his own arm, muttered a prayer to the god of the cave, and let a drop of his blood flow into the released blood of Yonyo and mingle with it. And thus was their marriage solemnized.

Then, with Yonyo's hand tucked in one of his hands and his club gripped in the other, he led his bride away with him into their secret nook among the shadows.

After they had disappeared, an excited chattering burst forth among the tribespeople, for never had so quiet a wedding been known before. The older and more experienced folk predicted that not many days would pass before Ru would be beating Yonyo with his club and taking another woman.

But soon they forgot all about Ru's marriage in contemplation of a more momentous event.

Curious throngs would gather daily to watch their chieftain and his chosen ten at practice with the "wonder stick"—and an atmosphere of dread anticipation filled the cavern, gradually rising to a pitch of apprehension that compelled prayers from the lips of the more fearful-minded and put the others in a constant state of shuddering excitement. For the people realized that the "wonder stick" was to be the ultimate test not only of Ru's power but of the tribe's chances for very life.

Ru himself understood this fact not less clearly than any of the others. He knew that the failure or success of the weapon would decide his own future and that of his people; and he looked forward to the approaching conflict with something of the sensations of a general who knows that a single defeat will mean disaster, a single victory win him an eternal crown.
