Shaking off the deadly sloth, they ran on again at full speed, peering through the stems in every direction. The effort made their brains throb fiercely. And still there was nothing before them and about them but the endless succession of slender gray stems and the downpour of that sinister rosy light. At last A-ya's steps began to lag, as if she were growing sleepy.

"Wake up!" shouted Grom, and dragged so fiercely at her arm that she cried out. But the pain aroused her to a new effort. She sprang forward, sobbing. The next moment, she was jerked violently to the left. "This way!" panted Grom, the sweat pouring down his livid face; and there, through the stems to the left, her dazed eyes perceived that the hated rosy glow was paling into the whiteness of the natural day.

It was a big white rock, an island thrust up through the sea of treacherous bloom. With fumbling, nerveless fingers they scaled its bare sides, flung themselves down among the scant but wholesome herbage, which clothed its top, and filled their lungs with the clean, reviving air. Dimly they heard a blessed buzzing of insects, and several great flies, with barred wings, lit upon them and bit them sharply. They lay with closed eyes, while slowly the throbbing in their brains died away and strength flowed back into their unstrung limbs.

Then, after perhaps an hour, Grom sat up and looked about him. On every side outspread the fatal flood of the rose-red oleanders, unbroken except toward the north-west. In that quarter, however, a spur of the giant forest, of growths too mighty to feel the spell of the envenomed blooms, was thrust deep into the crimson tide. Its tip came to within a couple of hundred yards of the rock. Having fully recovered, Grom and A-ya swung down, with loathing, into the pink gloom, fled through it almost without drawing breath, and found themselves once more in the rank green shadows of the jungle. They went on till they came to a thicket of plantains. Then, loading themselves with ripe fruit, they climbed high into a tree, and wove themselves a safe resting-place among the branches.

For the next few days their journey was without adventure, save for the frequent eluding of the monsters of that teeming world. Grom had his club, A-ya her broken spear; but they were avoiding all combats in their haste to get back to their own country of the homely caves and the guardian watch-fires. At the approach of the great black lion or the saber-tooth, or the wantonly malignant rhinoceros, they betook themselves to the tree-tops, and continued their way by that aerial path as long as it served them. The most subtle of the beasts they knew they could outwit, and their own anxiety now was Mawg, whose craft and courage Grom could no longer hold in scorn. He was doubtless at large, and quite possibly on their trail, biding his time to catch them unawares. They never allowed themselves, therefore, to sleep both at the same time. One always kept on guard: and hence their progress, for all their eagerness, was slower than it would otherwise have been.

On a certain day, after a long unbroken stretch of travel, A-ya rested and kept watch in a tree-top, while Grom went to fetch a bunch of plantains. It was fairly open country, a region of low herbage dotted with small groves and single trees; and the girl, herself securely hidden, could see in every direction. She could see Grom wandering from plantain clump to plantain clump, seeking fruit ripe enough to be palatable. And then, with a shiver of hate and dread, she saw the dark form of Mawg, creeping noiselessly on Grom's trail, and not more than a couple of hundred paces behind him. At the very moment when her eyes fell upon him, he dropped flat upon his face, and began worming his way soundlessly through the herbage.

Her mouth opened wide to give the alarm. But the cry stopped in her throat, and a smile of bitter triumph spread over her face.

If Mawg was hunting Grom, he was at the same time himself being hunted. And by a dreadful hunter.

Out from behind a thicket of glowing mimosa appeared a monstrous bird, some ten or twelve feet in height, lifting its feet very high in a swift but noiseless and curiously delicate stride. Its dark plumage was more like long, stringy hair than feathers. Its build was something like that of a gigantic ca.s.sowary, but its thighs and long blue shanks were proportionately more ma.s.sive. Its neck was long, but immensely muscular to support the enormous head, which was larger than that of a horse, and armed with a huge, hooked, rending, vulture's beak. The apparent length of this terrible head was increased by a pointed crest of blood-red feathers, projecting straight back in a line with the fore-part of the skull and the beak.

The crawling figure of Mawg was still a good hundred paces from the unsuspecting Grom, when the great bird overtook it. A-ya, watching from her tree-top, clutched a branch and held her breath. Mawg's ears caught a sound behind him, and he glanced around sharply. With a scream, he bounded to his feet. But it was too late. Before he could either strike or flee, he was beaten down again, with a smash of that pile-driving beak. The bird planted one huge foot on its victim's loins, gripped his head in its beak, and neatly snapped his neck. Then it fell greedily to its hideous meal.

At Mawg's scream of terror, Grom had turned and rushed to the rescue, swinging his club. But before he had covered half the distance, he saw that the monster had done its work; and he hesitated. He was too late to help the victim. And he knew the mettle of this ferocious bird, almost as much to be dreaded, in single combat, as the saber-tooth itself. At his approach, the bird had lifted its dripping beak, half turned, and stood gripping the prey with one foot, swaying its grim head slowly and eyeing him with malevolent defiance. Still he hesitated, fingering his club; for the insolence of that challenging stare made his blood seethe. Then came A-ya's voice from the tree-top, calling him. "Come away!" she cried. "It was Mawg."

Whereupon he turned, with the content of one who sees all old scores cleanly wiped out together, and went back to gather his ripe plantains.

The peril of Mawg being thus removed from their path, they journeyed more swiftly; and when the next new moon was a thin white sickle in the sky, just above the line of saw-toothed hills, they came safely back to the comfortable caves and the clear-burning watch-fires of their tribe.

CHAPTER VIII

THE BENDING OF THE BOW

Before the Caves of the Pointed Hills the fires of the tribe burned brightly. Within the caves reigned plenty and an unheard-of security; for since the conquest of fire those monstrous beasts and gigantic carnivorous, running birds, which had been Man's ceaseless menace ever since he swung down out of the tree-tops to walk the earth erect, had been held at a distance through awe of the licking flames. Though the great battle which had hurled back the invading hosts of the Bow-legs had cost the tribe more than half its warriors, the Caves were swarming with vigorous children. To Bawr, the Chief, and to Grom, his Right Hand and Councilor, the future of the tribe looked secure.

So sharp had been the lessons lately administered to the prowling beasts--the terrible saber-tooth, the giant red bear of the caves, the proud black lion, and the bone-crushing cave hyena--that even the stretch of b.u.mpy plain outside the circle of the fires, to a distance of several hundred paces, was considered a safe playground for the children of the tribe. On the outermost skirts of this playground, to be sure, just where the reedy pools and the dense bamboo thickets began, there was a fire kept burning. But this was more as a reminder than as an actual defense. When a bear or a saber-tooth had once had a blazing brand thrust in his face, he acquired a measure of discretion.

Moreover, the activities of the tribe had driven all the game animals to some distance up the valley; and it was seldom that anything more formidable than a jackal or a civet-cat cared to come within a half-mile of the fires.

It was now two years since the rescue of A-ya from her captivity among the Bow-legs. Her child by Grom was a straight-limbed, fair-skinned lad of somewhere between four and five years. She sat cross-legged near the sentinel fire, some fifty yards or so from the edge of the thickets, and played with the lad, whose eyes were alight with eager intelligence. Behind her sprawled, playing contentedly with its toes and sucking a banana, a fat brown flat-nosed baby of some fourteen or fifteen months.

Both A-ya and the boy were interested in a new toy. It was, perhaps, the first whip. The boy had succeeded in tying a thin strip of green hide, something over three feet in length, to one end of a stick which was several inches longer. The uses of a whip came to him by unerring insight, and he began applying it to his mother's shoulders. The novelty of it delighted them both. A-ya, moreover, chuckled slyly at the thought that the procedure might, on some future occasion, be reversed, not without advantage to the cause of discipline.

At last the lithe lash, so enthusiastically wielded, stung too hard for even A-ya, with all her stoicism, to find it amusing. She s.n.a.t.c.hed the toy away and began playing with it herself. The lash, at its free end, chanced to be slit almost to the tip, forming a loop. The b.u.t.t of the handle was formed by a jagged knot, where it had been broken from the parent stem. Idly but firmly, with her strong hands she bent the stick, and slipped the loop over the jagged knot, where it held.

Interested, but with no hint of comprehension in her bright eyes, she looked upon the first bow--the stupendous product of a child and a woman playing.

The child, displeased at this new, useless thing, and wanting his whip back, tried to s.n.a.t.c.h the bow from his mother's hands. But she pushed him off. She liked this new toy. It looked, somehow, as if it invited her to do something with it. Presently she pulled the cord, and let it go again. Tightly strung, it made a pleasant little humming sound.

This she repeated many times, holding it up to her ear and laughing with pleasure. The boy grew interested thereupon, and wanted to try the new game for himself. But A-ya was too absorbed. She would not let him touch it. "Go get another stick," she commanded impatiently; but quite forgot to see her command obeyed.

As she was tw.a.n.ging the strange implement which had so happily fashioned itself under her hands, Grom came up behind her. He stepped carefully over the sprawling brown baby. He was about to pull her heavy hair affectionately; but his eyes fell upon the thing in her hands, and he checked himself.

For minute after minute he stood there motionless, watching and studying the new toy. His eyes narrowed, his brows drew themselves down broodingly. The thing seemed to him to suggest dim, cloudy, vast possibilities; and he groped in his brain for some hint of the nature of these possibilities. Yet as far as he could see it was good for nothing but to make a faintly pleasant tw.a.n.g for the amus.e.m.e.nt of women and children. At last he could keep his hands off it no longer.

"Give it to me," said he suddenly, laying hold of A-ya's wrist.

But A-ya was not yet done with it. She held it away from him, and tw.a.n.ged it with redoubled vigor. Without further argument, and without violence, Grom reached out a long arm, and found the bow in his grasp.

A-ya was surprised that such a trifle should seem of such importance in her lord's eyes; but her faith was great. She shook the wild mane of hair back from her face, silenced the boy's importunings with an imperative gesture, and gathered herself with her arms about both knees to watch what Grom would do with the plaything.

First he examined it minutely, and then he fastened the thong more securely at either end. He tw.a.n.ged it as A-ya had done. He bent it to its limit and eased it slowly back again, studying the new force imprisoned in the changing curve. At last he asked who had made it.

"I did," answered A-ya, very proud of her achievement now that she found it taken so seriously by one being to whom her adventurous spirit really deferred.

"No, _I_ did!" piped the boy, with an injured air.

The mother laughed indulgently. "Yes, he tied one end, and beat me with it," said she. "Then I took it from him, and bent the stick and tied the other end."

"It is very good!" said Grom, nodding his approval musingly. He squatted down a few feet away, and began experimenting.

Picking up a small stone, he held it upon the cord, bent the bow a little way, and let go. The stone flew up and hit him with amazing energy in the mouth.

"_Oh!_" murmured A-ya, sympathetically, as the bright blood ran down his beard. But the child, thinking that his father had done it on purpose, laughed with hearty appreciation. Somewhat annoyed, Grom got up, moved a few paces farther away, and sat down again with his back to the family circle.

As to the force that lurked in this slender little implement he was now fully satisfied. But he was not satisfied with the direction in which it exerted itself. He continued his experiments, but was careful to draw the bow lightly.

For a long time he found it impossible to guess beforehand the direction which the pebbles, or the bits of stick or bark, would take in their surprising leaps from the loosed bow-string. But at length a dim idea of aim occurred to him. He lifted the bow--his left fist grasping its middle--to the level of his eyes, at arm's length. He got the cord accurately in the center of the pebble, and drew toward his nose. This effort was so successful that the stone went perfectly straight--and caught him fair on the thumb-knuckle.

The blow was so sharp that he dropped the bow with an angry exclamation. Glancing quickly over his shoulder to see if A-ya had noticed the incident, he observed that her face was buried between her knees and quite hidden by her hair. But her shoulders were heaving spasmodically. He suspected that she was laughing at him; and for a moment, as his knuckle was aching fiercely, he considered the advisability of giving her a beating. He had never done such a thing to her, however, though all the other Cave Men, including Bawr himself, were wont to beat their women on occasion. In his heart he hated the idea of hurting her; and it would hardly be worth while to beat her without hurting her. The idea, therefore, was promptly dismissed. He eyed the shaking shoulders gloomily for some seconds; and then, as the throbbing in the outraged knuckle subsided, a grin of sympathetic comprehension spread over his own face. He picked up the bow, sprang to his feet, and strolled over to the edge of a thicket of young cane.

The girl, lifting her head, peered at him cautiously through her hair.

Her laughter was forgotten on the instant, because she guessed that his fertile brain was on the trail of some new experiment.

Arriving at the cane-thicket, Grom broke himself half a dozen well-hardened, tapering stems, from two to three feet in length, and about as thick at their smaller ends as A-ya's little finger.

These seemed to suggest to him the possibility of better results than anything he could get from those erratic pebbles.

By this time quite a number of curious spectators--women and children mostly, the majority of the men being away hunting, and the rest too proud to show their curiosity--had gathered to watch Grom's experiments. They were puzzled to make out what it was he was busying himself with. But as he was a great chief, and held in deeper awe than even Bawr himself, they did not presume to come very near; and they had therefore not perceived, or at least they had not apprehended, those two trifling mishaps of his. As for Grom, he paid his audience no attention whatever. Now that he had possessed himself of those slender straight shafts of cane, all else was forgotten. He felt, as he looked at them and poised them, that in some vital way they belonged to this fascinating implement which A-ya had invented for him.

Selecting one of the shafts, he slowly applied the bigger end of it to the bow-string, and stood for a long time pondering it, drawing it a little way and easing it back without releasing it. Then he called to mind that his spears always threw better when they were hurled heavy end first. So he turned the little shaft and applied the small end to the bow-string. Then he pulled the string tentatively, and let it go.

The arrow, all unguided, shot straight up into the air, turned over, fell sharply, and buried its head in a bit of soft ground. Grom felt that this was progress. The spectators opened their mouths in wonder, but durst not venture any comment when Grom was at his mysteries.

Plucking the shaft from the earth, Grom once more laid it to the bow-string. As he pulled the string, the shaft wobbled crazily. With a growl of impatience, he clapped the fore-finger of his left hand over it, holding it in place, and pulled it through the guide thus formed.

A light flashed upon his brooding intelligence. Slightly crooking his finger, so that the shaft could move freely, he drew the string backward and forward, with deep deliberation, over and over again. To his delight, he found that the shaft was no longer eccentrically rebellious, but as docile as he could wish. At last, lifting the bow above his head, he drew it strongly, and shot the shaft into the air.

He shouted as it slipped smoothly through the guiding crook of his finger and went soaring skyward as if it would never stop. The eyes of the spectators followed its flight with awe, and A-ya, suddenly comprehending, caught her breath and s.n.a.t.c.hed the boy to her heart in a transport. Her alert mind had grasped, though dimly, the wonder of her man's achievement.

Now, though Grom had pointed his shaft skyward, he had taken no thought whatever as to its direction, or the distance it might travel.

As a matter of fact, he had shot towards the Caves. He had shot strongly; and that first bow was a stiff one. Most of the folk who squatted before the Caves were watching; but there were some who were too indifferent or too stupid to take an interest in anything less arresting than a thump on the head. Among these was a fat old woman, who, with her back to all the excitement, was bending herself double to grub in the litter of sticks and bones for some t.i.t-bit which she had dropped. Grom's shaft, turning gracefully against the blue came darting downward on a long slope, and buried its point in that upturned fat and grimy thigh. With a yell the old woman whipped round, tore out the shaft, dashed it upon the ground, stared at it in horror as if she thought it some kind of snake, and waddled, wildly jabbering, into the nearest cave.

An outburst of startled cries arose from all the spectators, but it hushed itself almost in the same breath. It was Grom who had done this singular thing, smiting unawares from very far off. The old woman must have done something to make Grom angry. They were all afraid; and several, whose consciences were not quite at ease, followed the old woman's example and slipped into the Caves.

As for Grom, his feelings were a mixture of embarra.s.sment and elation.
