Wulli was familiar with the habits of cave-beasts. They traveled all night, and their resting was done in the daytime. He, too, traveled all that night, but instead of following the trail he branched off in a wide detour at his utmost speed. This forced night march had as its object a return to the former relative positions of the Cave Beasts and himself. It was important that they be put back where they belonged, assuming that they belonged anywhere. To accomplish this, Wulli must overtake and pass them before daybreak, for he knew that at the first sign of light the Cave Beasts would slow up. They would skulk and crawl because of their aversion to being seen, thereby enabling the Rhinoceros to find and assume his rightful position in the line. It now remained for him to make good use of the wee small hours and circumvent his enemies without their knowing it. He proceeded to act accordingly.

The sky was becoming streaked with gray when Wulli arrived at the edge of a large grove. He judged that he must be considerably in advance of the Cave Beasts by this time, although his detour was not yet completed, and he must cover considerable ground before he could feel positive of having secured a safe lead. He plunged into and through the woods as fast as his legs would carry him. Several hours later he emerged upon the right bank of a river. Good; so far his plans had carried perfectly. The next thing was to pick up the Mammoth’s trail. This, too, was finally accomplished after a long search up the river bank. The scent of his friend was mingled with that of the odoriferous Hyena Man and Kutnar. He hunted everywhere for news of the Cave Beasts, but found none. Evidently they had not yet arrived. He had about made up his mind to enter the river when he smelled something that made him shiver. It was the odor of blood. A careful search led him to a clump of brush several rods from the bank. This place bore the scent of two men—Gonch and Kutnar. The blood was that of the boy. An ax lay near by. It was a mere stone tied to a stick, but the handle had a familiar smell.

Wulli groaned and almost collapsed. The boy had been hurt, perhaps killed. It was too dreadful to think of. His heart pounded like a hammer within his chest as he nosed about, following the Muskman’s tracks. They led to the river. All trace of Kutnar had disappeared. Wulli bit his lips and looked about him despairingly. What did it all mean?

Then came the sound of snapping wood as of branches pushed aside or trodden underfoot. The Cave Beasts had arrived! Wulli hurried to the river, plunged in and swam to the left bank. Here he stood wrist-deep in the water and waited.

A huge head thrust itself from among the trees, and then Grun Waugh’s huge form debouched majestically upon the distant right bank. Scrag and Crocut were close behind him.

“Two lions and a hyena,” thought Wulli. “Quite a number for me to manage.” Scrag was but an inexperienced cub and not much of a fighter, but he might be counted on to do something in a pinch. The Hyena was an unknown quantity. He appeared larger and different from the ordinary brand—a formidable adversary if he but knew and would use his powers. He might do so, seeing that his side was three against one. Grun Waugh was a host in himself. The trio were now entering the water. It was in Wulli’s mind to turn tail and flee in the hope of overtaking the Mammoth. With the latter’s assistance, Wulli felt no doubts as to the result if Grun Waugh chose to force an engagement. However, the Mammoth might be far away; then the Rhinoceros would be overtaken and compelled to fight the Cave Beasts all by himself. It would be on ground not of his own choosing, he remembered. The idea did not please him at all. He decided to stay where he was. He stood motionless in the shoals, watching the flotilla of heads bearing down upon him.

When no more than a stone’s throw separated the opposing forces, Grun Waugh suddenly uttered a surprised roar and backed water. The Rhinoceros blocked his way. He had taken for granted that Wulli was in full flight, but now he realized his mistake and at a most embarrassing moment. He dared not venture farther, for there was something suspicious in Wulli’s calm and receptive attitude. Grun Waugh knew him of old and therefore considered prudence the better part of valor. He deflected his course slightly downstream. By this act of courtesy he would avoid a collision with the Rhinoceros. Not to be outdone, the latter shifted his position to correspond. The Cave Lion found his enemy waiting to meet him, head-on as before. He growled with vexation, then turned and swam upstream. This was hard, battling against the swift current. Wulli kept pace with him. It required little exertion on his part, walking as he did on the river bottom. Grun Waugh snarled with rage. The Rhinoceros was determined to give him a warm welcome.

While their lord was vainly maneuvering for a landing, Scrag and Crocut conducted themselves in a most unbusiness-like manner. According to recognized naval rules, one or both of them should have outflanked the Rhinoceros while the latter faced Grun Waugh. In that case Wulli would have found himself in a most embarrassing position—attacked on several sides at once. However, Scrag and Crocut simplified matters by trailing after their leader. It being Grun Waugh’s fight and his part to do the dangerous work, the other two let it go at that. It did not occur to any of the three that this, their habitual practice, might be departed from in the present instance. The two lesser animals followed their leader, and whenever the latter tried to land he found the Rhinoceros ready and waiting for him.

Grun Waugh felt terribly incensed. With all his courage, he dared not advance and impale himself upon that terrible nose-horn. He reviled Wulli under his breath for his obstinacy, but that did him no good. Then he tried threats, roaring loudly and showing his cruel teeth. He was fearful to look upon, but the Rhinoceros failed to appreciate this. Having determined that he was pursuing the best possible course, he refused to budge from it. Not for an instant would he permit the Cave Lion to enter shallow water and rest himself.

“Go away,” roared Grun Waugh. “We will not hurt you this time, provided you stand aside and let us pass.”

“Pass where?” asked Wulli in his blandest manner. “Your home is behind you. You are going the wrong way.”

“And you will not stand aside?”

“Not if I can help it,” replied the Rhinoceros. “You do not belong here. Go home and take your hyenas back with you.”

Scrag nearly had a fit as he heard himself thus insulted. To be classed as a hyena was more than he could bear.

“Pig!” he wauled, forgetting his paddling. His head sank; the waters closed over it. When it reappeared, Scrag was blinded and half-choked, also the starch was taken out of him entirely. He was cold and tired and made up his mind then and there that he could be of more service to the world as a live lion than mere fish-food. He faced about, wheezing and panting, and sailed away on his return trip.

Crocut saw the young lion scudding past him. He was suddenly reminded that his wind and strength were ebbing fast. Just about enough fuel left in his bunkers to carry him back where he came from, so he, too, swung around and steered a straight course homeward.

Thus was the Cave Beast squadron shorn of much of its seeming strength. The battle was not yet over, however, for Grun Waugh still persisted in his efforts to effect a landing. But Wulli held the bridgehead, and the Cave Lion, try as he would, could accomplish nothing. Finally, he, too, gave up, tired and discouraged and steamed away, leaving the Rhinoceros in full possession of the field.

Wulli remained at his post for some time to make sure. When convinced that there was nothing more to be feared from the Cave Beasts, he again went about his business. For some time he trudged back and forth in an agony of indecision, but there seemed only one way to go—after the Mammoth whose comfort he yearned for and sorely needed. So he made that his choice, following untiringly over hill and valley, through glades and across swiftly flowing streams.

His woolly coat was torn and shabby and nearly every ounce of his superfluous flesh had been consumed, when at last he came to great mountains, so lofty their peaks seemed to touch the sky. He groaned dismally. Cliffs and high places were the last things on earth any rhinoceros would care to meet. Wulli would have given half of his life just then if the Mammoth and Pic had suddenly appeared before him, homeward bound. He hated mountains. They made him dizzy and weak at his knees and elbows. He gazed despairingly at the towering crests. The trail of his crony the Mammoth led to them, clear and unmistakable. There was no help for it. Wulli set his jaws tightly together, and with many misgivings for his future, plunged blindly and boldly upward among the peaks and crags.
