Far ahead of him a terror-stricken young woman was slinking along a narrow game-trail, fearful that the next moment would bring her face to face with some savage beast or equally savage man. As she ran on, hoping against hope that she had hit upon the direction that would lead her eventually to the great river, she came suddenly upon a familiar spot.

At one side of the trail, beneath a giant tree, lay a little heap of loosely piled brush—to her dying day that little spot of jungle would be indelibly impressed upon her memory. It was where Anderssen had hidden her—where he had given up his life in the vain effort to save her from Rokoff.

At sight of it she recalled the rifle and ammunition that the man had thrust upon her at the last moment. Until now she had forgotten them entirely. Still clutched in her hand was the revolver she had snatched from Rokoff's belt, but that could contain at most not over six cartridges—not enough to furnish her with food and protection both on the long journey to the sea.

With bated breath she groped beneath the little mound, scarce daring to hope that the treasure remained where she had left it; but, to her infinite relief and joy, her hand came at once upon the barrel of the heavy weapon and then upon the bandoleer of cartridges.

As she threw the latter about her shoulder and felt the weight of the big game-gun in her hand a sudden sense of security suffused her. It was with new hope and a feeling almost of assured success that she again set forward upon her journey.

That night she slept in the crotch of a tree, as Tarzan had so often told her that he was accustomed to doing, and early the next morning was upon her way again. Late in the afternoon, as she was about to cross a little clearing, she was startled at the sight of a huge ape coming from the jungle upon the opposite side.

The wind was blowing directly across the clearing between them, and Jane lost no time in putting herself downwind from the huge creature. Then she hid in a clump of heavy bush and watched, holding the rifle ready for instant use.

To her consternation she saw that the apes were pausing in the centre of the clearing. They came together in a little knot, where they stood looking backward, as though in expectation of the coming of others of their tribe. Jane wished that they would go on, for she knew that at any moment some little, eddying gust of wind might carry her scent down to their nostrils, and then what would the protection of her rifle amount to in the face of those gigantic muscles and mighty fangs?

Her eyes moved back and forth between the apes and the edge of the jungle toward which they were gazing until at last she perceived the object of their halt and the thing that they awaited. They were being stalked.

Of this she was positive, as she saw the lithe, sinewy form of a panther glide noiselessly from the jungle at the point at which the apes had emerged but a moment before.

Quickly the beast trotted across the clearing toward the anthropoids. Jane wondered at their apparent apathy, and a moment later her wonder turned to amazement as she saw the great cat come quite close to the apes, who appeared entirely unconcerned by its presence, and, squatting down in their midst, fell assiduously to the business of preening, which occupies most of the waking hours of the cat family.

If the young woman was surprised by the sight of these natural enemies fraternizing, it was with emotions little short of fear for her own sanity that she presently saw a tall, muscular warrior enter the clearing and join the group of savage beasts assembled there.

At first sight of the man she had been positive that he would be torn to pieces, and she had half risen from her shelter, raising her rifle to her shoulder to do what she could to avert the man's terrible fate.

Now she saw that he seemed actually conversing with the beasts—issuing orders to them.

Presently the entire company filed on across the clearing and disappeared in the jungle upon the opposite side.

With a gasp of mingled incredulity and relief Jane Clayton staggered to her feet and fled on away from the terrible horde that had just passed her, while a half-mile behind her another individual, following the same trail as she, lay frozen with terror behind an ant-hill as the hideous band passed quite close to him.

This one was Rokoff; but he had recognized the members of the awful aggregation as allies of Tarzan of the Apes. No sooner, therefore, had the beasts passed him than he rose and raced through the jungle as fast as he could go, in order that he might put as much distance as possible between himself and these frightful beasts.

So it happened that as Jane Clayton came to the bank of the river, down which she hoped to float to the ocean and eventual rescue, Nikolas Rokoff was but a short distance in her rear.

Upon the bank the girl saw a great dugout drawn half-way from the water and tied securely to a near-by tree.

This, she felt, would solve the question of transportation to the sea could she but launch the huge, unwieldy craft. Unfastening the rope that had moored it to the tree, Jane pushed frantically upon the bow of the heavy canoe, but for all the results that were apparent she might as well have been attempting to shove the earth out of its orbit.

She was about winded when it occurred to her to try working the dugout into the stream by loading the stern with ballast and then rocking the bow back and forth along the bank until the craft eventually worked itself into the river.

There were no stones or rocks available, but along the shore she found quantities of driftwood deposited by the river at a slightly higher stage. These she gathered and piled far in the stern of the boat, until at last, to her immense relief, she saw the bow rise gently from the mud of the bank and the stern drift slowly with the current until it again lodged a few feet farther down-stream.

Jane found that by running back and forth between the bow and stern she could alternately raise and lower each end of the boat as she shifted her weight from one end to the other, with the result that each time she leaped to the stern the canoe moved a few inches farther into the river.

As the success of her plan approached more closely to fruition she became so wrapped in her efforts that she failed to note the figure of a man standing beneath a huge tree at the edge of the jungle from which he had just emerged.

He watched her and her labours with a cruel and malicious grin upon his swarthy countenance.

The boat at last became so nearly free of the retarding mud and of the bank that Jane felt positive that she could pole it off into deeper water with one of the paddles which lay in the bottom of the rude craft. With this end in view she seized upon one of these implements and had just plunged it into the river bottom close to the shore when her eyes happened to rise to the edge of the jungle.

As her gaze fell upon the figure of the man a little cry of terror rose to her lips. It was Rokoff.

He was running toward her now and shouting to her to wait or he would shoot—though as he was entirely unarmed it was difficult to discover just how he intended making good his threat.

Jane Clayton knew nothing of the various misfortunes that had befallen the Russian since she had escaped from his tent, so she believed that his followers must be close at hand.

However, she had no intention of falling again into the man's clutches. She would rather die at once than that that should happen to her. Another minute and the boat would be free.

Once in the current of the river she would be beyond Rokoff's power to stop her, for there was no other boat upon the shore, and no man, and certainly not the cowardly Rokoff, would dare to attempt to swim the crocodile-infested water in an effort to overtake her.

Rokoff, on his part, was bent more upon escape than aught else. He would gladly have forgone any designs he might have had upon Jane Clayton would she but permit him to share this means of escape that she had discovered. He would promise anything if she would let him come aboard the dugout, but he did not think that it was necessary to do so.

He saw that he could easily reach the bow of the boat before it cleared the shore, and then it would not be necessary to make promises of any sort. Not that Rokoff would have felt the slightest compunction in ignoring any promises he might have made the girl, but he disliked the idea of having to sue for favour with one who had so recently assaulted and escaped him.

Already he was gloating over the days and nights of revenge that would be his while the heavy dugout drifted its slow way to the ocean.

Jane Clayton, working furiously to shove the boat beyond his reach, suddenly realized that she was to be successful, for with a little lurch the dugout swung quickly into the current, just as the Russian reached out to place his hand upon its bow.

His fingers did not miss their goal by a half-dozen inches. The girl almost collapsed with the reaction from the terrific mental, physical, and nervous strain under which she had been labouring for the past few minutes. But, thank Heaven, at last she was safe!

Even as she breathed a silent prayer of thanksgiving, she saw a sudden expression of triumph lighten the features of the cursing Russian, and at the same instant he dropped suddenly to the ground, grasping firmly upon something which wriggled through the mud toward the water.

Jane Clayton crouched, wide-eyed and horror-stricken, in the bottom of the boat as she realized that at the last instant success had been turned to failure, and that she was indeed again in the power of the malignant Rokoff.

For the thing that the man had seen and grasped was the end of the trailing rope with which the dugout had been moored to the tree.

Chapter 15

Down the Ugambi

Halfway between the Ugambi and the village of the Waganwazam, Tarzan came upon the pack moving slowly along his old spoor. Mugambi could scarce believe that the trail of the Russian and the mate of his savage master had passed so close to that of the pack.

It seemed incredible that two human beings should have come so close to them without having been detected by some of the marvellously keen and alert beasts; but Tarzan pointed out the spoor of the two he trailed, and at certain points the black could see that the man and the woman must have been in hiding as the pack passed them, watching every move of the ferocious creatures.

It had been apparent to Tarzan from the first that Jane and Rokoff were not travelling together. The spoor showed distinctly that the young woman had been a considerable distance ahead of the Russian at first, though the farther the ape-man continued along the trail the more obvious it became that the man was rapidly overhauling his quarry.

At first there had been the spoor of wild beasts over the footprints of Jane Clayton, while upon the top of all Rokoff's spoor showed that he had passed over the trail after the animals had left their records upon the ground. But later there were fewer and fewer animal imprints occurring between those of Jane's and the Russian's feet, until as he approached the river the ape-man became aware that Rokoff could not have been more than a few hundred yards behind the girl.

He felt they must be close ahead of him now, and, with a little thrill of expectation, he leaped rapidly forward ahead of the pack. Swinging swiftly through the trees, he came out upon the river-bank at the very point at which Rokoff had overhauled Jane as she endeavoured to launch the cumbersome dugout.

In the mud along the bank the ape-man saw the footprints of the two he sought, but there was neither boat nor people there when he arrived, nor, at first glance, any sign of their whereabouts.

It was plain that they had shoved off a native canoe and embarked upon the bosom of the stream, and as the ape-man's eye ran swiftly down the course of the river beneath the shadows of the overarching trees he saw in the distance, just as it rounded a bend that shut it off from his view, a drifting dugout in the stern of which was the figure of a man.

Just as the pack came in sight of the river they saw their agile leader racing down the river's bank, leaping from hummock to hummock of the swampy ground that spread between them and a little promontory which rose just where the river curved inward from their sight.

To follow him it was necessary for the heavy, cumbersome apes to make a wide detour, and Sheeta, too, who hated water. Mugambi followed after them as rapidly as he could in the wake of the great white master.
