Kala had moved slowly along an elephant track toward the east, and was busily engaged in turning over rotted limbs and logs in search of succulent bugs and fungi, when the faintest shadow of a strange noise brought her to startled attention.

For fifty yards before her the trail was straight, and down this leafy tunnel she saw the stealthy advancing figure of a strange and fearful creature.

It was Kulonga.

Kala did not wait to see more, but, turning, moved rapidly back along the trail. She did not run; but, after the manner of her kind when not aroused, sought rather to avoid than to escape.

Close after her came Kulonga. Here was meat. He could make a killing and feast well this day. On he hurried, his spear poised for the throw.

At a turning of the trail he came in sight of her again upon another straight stretch. His spear hand went far back, the muscles rolled, lightning-like, beneath the sleek hide. Out shot the arm, and the spear sped toward Kala.

A poor cast. It but grazed her side.

With a cry of rage and pain the she-ape turned upon her tormentor. In an instant the trees were crashing beneath the weight of her hurrying fellows, swinging rapidly toward the scene of trouble in answer to Kala's scream.

As she charged, Kulonga unslung his bow and fitted an arrow with almost unthinkable quickness. Drawing the shaft far back he drove the poisoned missile straight into the heart of the great anthropoid.

With a horrid scream Kala plunged forward upon her face before the astonished members of her tribe.

Roaring and shrieking the apes dashed toward Kulonga, but that wary savage was fleeing down the trail like a frightened antelope.

He knew something of the ferocity of these wild, hairy men, and his one desire was to put as many miles between himself and them as he possibly could.

They followed him, racing through the trees, for a long distance, but finally one by one they abandoned the chase and returned to the scene of the tragedy.

None of them had ever seen a man before, other than Tarzan, and so they wondered vaguely what strange manner of creature it might be that had invaded their jungle.

On the far beach by the little cabin Tarzan heard the faint echoes of the conflict and knowing that something was seriously amiss among the tribe he hastened rapidly toward the direction of the sound.

When he arrived he found the entire tribe gathered jabbering about the dead body of his slain mother.

Tarzan's grief and anger were unbounded. He roared out his hideous challenge time and again. He beat upon his great chest with his clenched fists, and then he fell upon the body of Kala and sobbed out the pitiful sorrowing of his lonely heart.

To lose the only creature in all his world who ever had manifested love and affection for him was the greatest tragedy he had ever known.

What though Kala was a fierce and hideous ape! To Tarzan she had been kind, she had been beautiful.

Upon her he had lavished, unknown to himself, all the reverence and respect and love that a normal English boy feels for his own mother.

He had never known another, and so to Kala was given, though mutely, all that would have belonged to the fair and lovely Lady Alice had she lived.

After the first outburst of grief Tarzan controlled himself, and questioning the members of the tribe who had witnessed the killing of Kala he learned all that their meager vocabulary could convey.

It was enough, however, for his needs. It told him of a strange, hairless, black ape with feathers growing upon its head, who launched death from a slender branch, and then ran, with the fleetness of Bara, the deer, toward the rising sun.

Tarzan waited no longer, but leaping into the branches of the trees sped rapidly through the forest. He knew the windings of the elephant trail along which Kala's murderer had flown, and so he cut straight through the jungle to intercept the black warrior who was evidently following the tortuous detours of the trail.

At his side was the hunting knife of his unknown sire, and across his shoulders the coils of his own long rope. In an hour he struck the trail again, and coming to earth examined the soil minutely.

In the soft mud on the bank of a tiny rivulet he found footprints such as he alone in all the jungle had ever made, but much larger than his.

His heart beat fast. Could it be that he was trailing a MAN--one of his own race?

There were two sets of imprints pointing in opposite directions. So his quarry had already pa.s.sed on his return along the trail. As he examined the newer spoor a tiny particle of earth toppled from the outer edge of one of the footprints to the bottom of its shallow depression--ah, the trail was very fresh, his prey must have but scarcely pa.s.sed.

Tarzan swung himself to the trees once more, and with swift noiselessness sped along high above the trail.

He had covered barely a mile when he came upon the black warrior standing in a little open s.p.a.ce. In his hand was his slender bow to which he had fitted one of his death dealing arrows.

Opposite him across the little clearing stood Horta, the boar, with lowered head and foam flecked tusks, ready to charge.

Tarzan looked with wonder upon the strange creature beneath him--so like him in form and yet so different in face and color. His books had portrayed the NEGRO, but how different had been the dull, dead print to this sleek thing of ebony, pulsing with life.

As the man stood there with taut drawn bow Tarzan recognized him not so much the NEGRO as the ARCHER of his picture book--

A stands for Archer

How wonderful! Tarzan almost betrayed his presence in the deep excitement of his discovery.

But things were commencing to happen below him. The sinewy black arm had drawn the shaft far back; Horta, the boar, was charging, and then the black released the little poisoned arrow, and Tarzan saw it fly with the quickness of thought and lodge in the bristling neck of the boar.

Scarcely had the shaft left his bow ere Kulonga had fitted another to it, but Horta, the boar, was upon him so quickly that he had no time to discharge it. With a bound the black leaped entirely over the rushing beast and turning with incredible swiftness planted a second arrow in Horta's back.

Then Kulonga sprang into a near-by tree.

Horta wheeled to charge his enemy once more; a dozen steps he took, then he staggered and fell upon his side. For a moment his muscles stiffened and relaxed convulsively, then he lay still.

Kulonga came down from his tree.

With a knife that hung at his side he cut several large pieces from the boar's body, and in the center of the trail he built a fire, cooking and eating as much as he wanted. The rest he left where it had fallen.

Tarzan was an interested spectator. His desire to kill burned fiercely in his wild breast, but his desire to learn was even greater. He would follow this savage creature for a while and know from whence he came.

He could kill him at his leisure later, when the bow and deadly arrows were laid aside.

When Kulonga had finished his repast and disappeared beyond a near turning of the path, Tarzan dropped quietly to the ground. With his knife he severed many strips of meat from Horta's carca.s.s, but he did not cook them.

He had seen fire, but only when Ara, the lightning, had destroyed some great tree. That any creature of the jungle could produce the red-and-yellow fangs which devoured wood and left nothing but fine dust surprised Tarzan greatly, and why the black warrior had ruined his delicious repast by plunging it into the blighting heat was quite beyond him. Possibly Ara was a friend with whom the Archer was sharing his food.

But, be that as it may, Tarzan would not ruin good meat in any such foolish manner, so he gobbled down a great quant.i.ty of the raw flesh, burying the balance of the carca.s.s beside the trail where he could find it upon his return.

And then Lord Greystoke wiped his greasy fingers upon his naked thighs and took up the trail of Kulonga, the son of Mbonga, the king; while in far-off London another Lord Greystoke, the younger brother of the real Lord Greystoke's father, sent back his chops to the club's CHEF because they were underdone, and when he had finished his repast he dipped his finger-ends into a silver bowl of scented water and dried them upon a piece of snowy damask.

All day Tarzan followed Kulonga, hovering above him in the trees like some malign spirit. Twice more he saw him hurl his arrows of destruction--once at Dango, the hyena, and again at Manu, the monkey.

In each instance the animal died almost instantly, for Kulonga's poison was very fresh and very deadly.

Tarzan thought much on this wondrous method of slaying as he swung slowly along at a safe distance behind his quarry. He knew that alone the tiny p.r.i.c.k of the arrow could not so quickly dispatch these wild things of the jungle, who were often torn and scratched and gored in a frightful manner as they fought with their jungle neighbors, yet as often recovered as not.

No, there was something mysterious connected with these tiny slivers of wood which could bring death by a mere scratch. He must look into the matter.

That night Kulonga slept in the crotch of a mighty tree and far above him crouched Tarzan of the Apes.
