CHAPTER IX. The theft of the jewels. For two days Werper sought for the party that had accompanied him from the camp to the barrier-cliffs, but not until late in the afternoon of the second day did he find clue to its whereabouts, and then in such gruesome form that he was totally unnerved by the sight. In an open glade he came upon the bodies of three of the blacks, terribly mutilated, nor did it require considerable deductive power to explain their murder. Of the little party only these three had not been slaves. The others evidently tempted to hope for freedom from their cruel Arab master had taken advantage of their separation from the main camp to slay the three representatives of the hated power which held them in slavery and vanish into the jungle. Cold sweat exuded from Werper's forehead as he contemplated the fate which Chance had permitted him to escape, for had he been present when the conspiracy bore fruit he too must have been of the garnered. Tarzan showed not the slightest surprise or interest in the discovery. Inherent in him was a callous familiarity with violent death. The refinements of his recent civilization, expunged by the force of the sad calamity which had befallen him, left only the primitive sensibilities which his childhood's training had imprinted indelibly upon the fabric of his mind. The training of Kala, the examples and precepts of Kerchak, of Tublat, and of Turkos now formed the basis of his every thought and action. He retained a mechanical knowledge of French and English speech. Werper had spoken to him in French, and Tarzan had replied in the same tongue without conscious realization that he had departed from the anthropoidal speech in which he had addressed law. Had Werper used English the result would have been the same. Again that night, as the two sat before their campfire, Tarzan played with his shining baubles. Werper asked him what they were and where he had found them. The eight-man replied that they were gay-colored stones with which he purposed fashioning and necklace, and that he had found them far beneath the sacrificial court of the temple of the flaming god. Werper was relieved to find that Tarzan had no conception of the value of the gems. This would make it easier for the Belgian to obtain possession of them. Possibly the man would give them to him for the asking. Werper reached out his hand toward the little pile that Tarzan had arranged upon a piece of flat wood before him. Let me see them, said the Belgian. Tarzan placed a large palm over his treasure. He bared his fighting fangs and growled. Werper withdrew his hand more quickly than he had advanced it. Tarzan resumed his playing with the gems and his conversation with Werper as though nothing unusual had occurred. He had but exhibited the beast's jealous protective instinct for a possession. When he killed he shared the meat with Werper, but had Werper ever by accident laid a hand upon Tarzan's share he would have aroused the same savage and resentful warning. From that occurrence dated the beginning of a great fear in the breast of the Belgian for his savage companion. He had never understood the transformation that had been wrought in Tarzan by the blow upon his head, other than to attribute it to a form of amnesia. That Tarzan had once been, in truth, a savage jungle beast Werper had not known, and so of course he could not guess that the man had reverted to the state in which his childhood and young manhood had been spent. Now Werper saw in the Englishman a dangerous maniac whom the slightest untoward accident might turn upon him with rending fangs. Not for a moment did Werper attempt to delude himself into the belief that he could defend himself successfully against an attack by the eight man. His one hope lay in eluding him and making for the far distant camp of Ochmek Zek as rapidly as he could. But armed only with the sacrificial knife, Werper shrank from attempting the journey through the jungle. Tarzan constituted a protection that was by no means despicable, even in the face of the larger carnivora, as Werper had reason to acknowledge from the evidence he had witnessed in the Oparian temple. Two, Werper had his covetous soul set upon the pouch of gems, and so he was torn between the various emotions of avarice and fear. But avarice it was that burned most strongly in his breast to the end that he dared the dangers and suffered the terrors of constant association with him he thought a madman, rather than give up the hope of obtaining possession of the fortune which the contents of the little pouch represented. Ochmek Zek should know nothing of these, these would be for Werper alone, and so soon as he could encompass his design he would reach the coast and take passage for America where he could conceal himself beneath the veil of a new identity and enjoy to some measure the fruits of his theft. He had it all planned out, did Lieutenant Albert Werper, living in anticipation the luxurious life of the idle rich. He even found himself regretting that America was so provincial and that nowhere in the New World was a city that might compare with his beloved Brussels. It was upon the third day of their progress from Opar that the keen ears of Tarzan caught the sound of men behind him. Werper heard nothing above the humming of the jungle insects and the chattering life of the lesser monkeys and the birds. For a time Tarzan stood in statuesque silence, listening, his sensitive nostrils dilating as he assayed each passing breeze. Then he withdrew Werper into the concealment of thick brush, and waited. Presently along the game trail that Werper and Tarzan had been following there came inside a sleek black warrior, alert and watchful. In single file behind him there followed one after another, near fifty others, each burdened with two dull yellow ingots lashed upon his back. Werper recognized the party immediately as that which had accompanied Tarzan on his journey to Opar. He glanced at the ape-man, but in the savage watchful eyes he saw no recognition of Basouli and those other loyal Waziri. When all had passed Tarzan rose and emerged from concealment. He looked down the trail in the direction the party had gone. Then he turned to Werper. We will follow and slay them, he said. Why, asked the Belgian. They are black, explained Tarzan.  They are the enemies of the Manganese. Werper did not relish the idea of engaging in a battle with Basouli and his fierce fighting-man. And again he had welcomed the sight of them returning toward the grey-stoke bungalow, for he had begun to have doubts as to his ability to retrace his steps to the Waziri country. Tarzan, he knew, had not the remotest idea of whither they were going. By keeping at a safe distance behind the Laidon warriors they would have no difficulty in following them home. Once at the bungalow, Werper knew the way to the camp of Ochmatzek. There was still another reason why he did not wish to interfere with the Waziri. They were bearing the great burden of treasure in the direction he wished it born. The farther they took it the less the distance that he and Ochmatzek would have to transport it. He argued with the ape-man, therefore, against the latter's desire to exterminate the blacks, and at last he prevailed upon Tarzan to follow them in peace, saying that he was sure they would lead them out of the forest into a rich country teaming with game. It was many marches from Opar to the Waziri country, but at last came the hour when Tarzan and the Belgian, following the trail of the warriors, topped the last rise and saw before them the broad Waziri plain, the winding river, and the distant forests to the north and west. A mile or more ahead of them the line of warriors was creeping like a giant caterpillar through the tall grasses of the plain. Beyond grazing herds of zebra, heart of beast, and topi dotted the level landscape, while closer to the river a bull buffalo, his head and shoulders protruding from the reeds, watched the advancing blacks for a moment only to turn at last and disappear into the safety of his dank and gloomy retreat. Tarzan looked out across the familiar vista with no faintest gleam of recognition in his eyes. He saw the game animals and his mouth watered, but he did not look in the direction of his bungalow. Werper, however, did. A puzzled expression entered the Belgian's eyes. He shaded them with his palms and gazed long and earnestly toward the spot where the bungalow had stood. He could not credit the testimony of his eyes. There was no bungalow, no barns, no outhouses. The corrals, the haystacks, all were gone. What could it mean? And then slowly there filtered into Werper's consciousness an explanation of the havoc that had been wrought in that peaceful valley since last his eyes had rested upon it. Ack met Zeck had been there. Basouli and his warriors had noted the devastation the moment they had come inside of the farm. Now they hastened on toward it talking excitedly among themselves, in animated speculation upon the cause and meaning of the catastrophe. When at last they crossed the trampled garden and stood before the charred ruins of their master's bungalow, their greatest fears became convictions in the light of the evidence about them. Remnants of human dead, half devoured by prowling hyenas and others of the carnivora which infested the region, lay rotting upon the ground, and among the corpses remained sufficient remnants of their clothing and ornaments to make clear to Basouli the frightful story of the disaster that had befallen his master's house. The A-Rabs, he said, as his men clustered about him. The Waziri gazed about in mute rage for several minutes. Everywhere they encountered only further evidence of the ruthlessness of the cruel enemy that had come during the Great Buona's absence and laid waste his property. What did they with Lady? asked one of the blacks. They had always called Lady Greystoke Bess. The women they would have taken with them, said Basouli. Our women and his.  The others followed his example. Basouli silenced them with a gesture. This is no time for useless noises of the mouth, he said. The Great Buona has taught us that it is acts by which things are done, not words. Let us save our breath. We shall need it all to follow up the A-Rabs and slay them. If Lady and our women live, the greater the need of haste and warriors cannot travel fast upon empty lungs. From the shelter of the reeds along the river Werper and Tarzan watched the blacks. They saw them dig a trench with their knives and fingers. They saw them lay their yellow burdens in it and scooped the overturned earth back over the tops of the ingots. Tarzan seemed little interested after Werper had assured him that that which they buried was not good to eat, but Werper was intensely interested. He would have given much had he had his own followers with him, that he might take away the treasure as soon as the blacks left, for he was sure that they would leave this scene of desolation and death as soon as possible. The treasure buried the blacks removed themselves a short distance upwind from the fetid corpses where they made camp that they might rest before setting out in pursuit of the A-Rabs. It was already dusk, Werper and Tarzan sat devouring some pieces of meat they had brought from their last camp. The Belgian was occupied with his plans for the immediate future. He was positive that the Waziri would pursue, ought met Zeck, for he knew enough of savage warfare and of the characteristics of the A-Rabs and their degraded followers to guess that they had carried the Waziri women off into slavery. This alone would assure immediate pursuit by so warlike a people as the Waziri. Werper felt that he should find the means and the opportunity to push on ahead that he might warn Achmed Zeck of the coming of Besouli and also of the location of the buried treasure. What the A-Rab would now do with Lady Grey Stoke in view of the mental affliction of her husband, Werper neither knew nor cared. It was enough that the golden treasure buried upon the side of the burned bungalow was infinitely more valuable than any ransom that would have occurred even to the avaricious mind of the A-Rab, and if Werper could persuade the raider to share even a portion of it with him, he would be well satisfied. But by far the most important consideration to Werper, at least, was the incalculably valuable treasure in the little leather pouch at Tarzan's side. If he could but obtain possession of this, he must, he would. His eyes wandered to the object of his greed. They measured Tarzan's giant frame and rested upon the rounded muscles of his arms. It was hopeless. What could he, Werper, hope to accomplish other than his own death by an attempt to rest the gems from their savage owner? Disconsolate, Werper threw himself upon his side. His head was pillowed on one arm, the other rested across his face in such a way that his eyes were hidden from the eight-man, though one of them was fastened upon him from beneath the shadow of the Belgian's forearm. For a time he lay thus, glowering at Tarzan, and originating schemes for plundering him of his treasure, schemes that were discarded as futile as rapidly as they were born.  The Belgians saw that he was being watched and lay very still. After a few moments he simulated the regular breathing of deep slumber. Tarzan had been thinking. He had seen the Waziri bury their belongings. Werper had told him that they were hiding them lest someone find them and take them away. This seemed to Tarzan a splendid plan for safeguarding valuables.  For a long time the eight-man sat watching his companion. At last, convinced that he slept, Tarzan withdrew his hunting-knife and commenced to dig a hole in the ground before him. With the blade he loosened up the earth, and with his hands he scooped it out until he had excavated a little cavity a few inches in diameter and five or six inches in depth. Into this he placed the pouch of jewels. Werper almost forgot to breathe after the fashion of a sleeper as he saw what the eight-man was doing. He scarce repressed an ejaculation of satisfaction. Tarzan became suddenly rigid as his keen ears noted the secession of the regular inspirations and expirations of his companion. His narrowed eyes bored straight down upon the Belgian. Werper felt that he was lost. He must risk all on his ability to carry on the deception. He sighed, threw both arms outward, and turned over on his back, mumbling as though in the throes of a bad dream. A moment later he resumed the regular breathing. Now he could not watch, Tarzan, but he was sure that the man sat for a long time looking at him. Then faintly Werper heard the other's hand scraping dirt and later patting it down. He knew then that the jewels were buried. It was an hour before Werper moved again. Then he rolled over facing Tarzan and opened his eyes. The eight-man slept. By reaching out his hand Werper could touch the spot where the pouch was buried. For a long time he lay watching and listening. He moved about, making more noise than necessary. Yet Tarzan did not awaken. He drew the sacrificial knife from his belt and plunged it into the ground. Tarzan did not move. Cautiously the Belgian pushed the blade downward through the loose earth above the pouch. He felt the point touch the soft, tough fabric of the leather. Then he pried down upon the handle. Slowly the little mound of loose earth rose and parted. An instant later a corner of the pouch came into view. Werper pulled it from its hiding place and tucked it in his shirt. Then he refilled the hole and pressed the dirt carefully down as it had been before. Greed had prompted him to enact the discovery of which, by his companion, could lead only to the most frightful consequences for Werper. Already he could almost feel those strong white fangs burying themselves in his neck, he shuddered. Far out across the plain a leopard screamed, and in the dense reeds behind him some great beast moved on padded feet. Werper feared these prowlers of the night, but infinitely more he feared the just wrath of the human beast sleeping at his side. With utmost caution the Belgian arose. Tarzan did not move. Werper took a few steps toward the plain and the distant forest to the northwest. Then he paused and fingered the hilt of the long knife in his belt. He turned and looked down upon the sleeper. Why not, he mused, then I should be safe. He returned and bent above the ape-man. Clutched tightly in his hand was the sacrificial knife of the high priestess of the flaming god.

Tarzan and the Jewels of Opar by Edgar Rice Burroughs Chapter 10 Ockmet Zeck Sees the Jewels Mugambi, weak and suffering, had dragged his painful way along the trail of the retreating raiders. He could move but slowly, resting often, but savage hatred and unequally savage desire for vengeance kept him to his task. As the days passed his wounds healed and his strength returned until at last his giant frame had regained all of its former mighty powers. Now he went more rapidly, but the mounted A-Rabs had covered a great distance while the wounded black had been painfully crawling after them. They had reached their fortified camp, and their Ockmet Zeck awaited the return of his Lieutenant Albert Werper. During the long rough journey Jane Clayton had suffered more in anticipation of her impending fate than from the hardships of the road. Ockmet Zeck had not deigned to acquaint her with his intentions regarding her future. She prayed that she had been captured in the hope of ransom, for if such should prove the case no great harm would befall her at the hands of the A-Rabs. But there was the chance, the horrid chance, that another fate awaited her. She had heard of many women, among whom were white women, who had been sold by outlaws such as Ockmet Zeck into the slavery of black harems, or taken farther north into the almost equally hideous existence of some turkey's sorralio. Jane Clayton was of sterner stuff than that which bends in spineless terror before danger, until hope proved futile she would not give it up, nor did she entertain thoughts of self-destruction only as a final escape from dishonor. So long as Tarzan lived there was every reason to expect succor. No man nor beast who roamed the savage continent could boast the cunning and the powers of her lord and master. To her he was little short of omnipotent in his native world, this world of savage beasts and savage men. Tarzan would come, and she would be rescued and avenged. Of that she was certain. She counted the days that must elapse before he would return from Opar and discover what had transpired during his absence. After that it would be but a short time before he had surrounded the Arab stronghold and punished the motley crew of wrong doers who inhabited it. That he could find her she had no slightest doubt, no spore, however faint could elude the keen vigilance of his senses. To him the trail of the raiders would be as plain as the printed page of an open book to her, and while she hoped there came through the dark jungle another, terrified by night and by day came Albert Werper. A dozen times he had escaped the claws and fangs of the giant carnivora only by what seemed a miracle to him. Armed with nothing more than the knife he had brought with him from Opar, he had made his way through as savage a country as yet exists upon the face of the globe. By night he had slept in trees, by day he had stumbled fearfully on, often taking refuge among the branches when sight or sound of some great cat warned him from danger. But at last he had come within sight of the palisade, behind which were his fierce companions. At almost the same time Mugambi came out of the jungle before the walled village. As he stood in the shadow of a great tree, reconnoitering, he saw a man ragged and disheveled emerge from the jungle almost at his elbow. Instantly he recognized the newcomer as he who had been a guest of his master before the latter had departed for Opar. The black was upon the point of hailing the Belgian when something stayed him. He saw the white man walking confidently across the clearing toward the village gate. No sane man thus approached a village in this part of Africa unless he was sure of a friendly welcome. Mugambi waited, his suspicions were aroused. He heard whirper halloo, he saw the gates swing open, and he witnessed the surprised and friendly welcome that was accorded the erstwhile guest of Lord and Lady Greystoke.  It was to him they owed the raid, during the absence of the great Boana, to his hate for the Arab's Mugambi added a still greater hate for the white spy. Within the village whirper passed hurriedly toward the silken tent of Akmet Zak. The Arab arose as his lieutenant entered. His face showed surprise as he viewed the tattered apparel of the Belgian. "'Fought has happened,' he asked. Whirper narrated all, saved the little matter of the pouch of gems which were now tightly strapped about his waist beneath his clothing. The Arab's eyes narrowed greedily as his henchmen described the treasure that the Waziri had buried beside the ruins of the Greystoke bungalow. "'Eat we'll be a simpler matter now to return and get it,' said Akmet Zak. "'First we will await the coming of the rash Waziri, and after we have slain them we may take our time to the treasure. None will disturb it where it lies, for we shall leave none alive who knows of its existence.' "'And the woman,' asked Whirper. "'I shall sell her in the north,' replied the raider. "'Eat is the only way now. She should bring a good price.' The Belgian nodded. He was thinking rapidly. If he could persuade Akmet Zak to send him in command of the party which took Lady Greystoke north it would give him the opportunity he craved to make his escape from his chief. He would forego a share of the gold if he could but get away unscathed with the jewels. He knew Akmet Zak well enough by this time to know that no member of his band ever was voluntarily released from the service of Akmet Zak. Most of the few who deserted were recaptured. More than once had Whirper listened to their agonized screams as they were tortured before being put to death. The Belgian had no wish to take the slightest chance of recapture. "'Who will go north with the woman?' he asked, while we are returning for the gold that the Waziri buried by the bungalow of the Englishman?' Akmet Zak thought for a moment. The buried gold was of much greater value than the price the woman would bring. It was necessary to rid himself of her as quickly as possible, and it was also well to obtain the gold with the least possible delay. Of all his followers the Belgian was the most logical lieutenant to entrust with the command of one of his parties. An Arab as familiar with the Trails and Tribes as Akmet Zak himself might collect the woman's price and make good his escape into the far north. Whirper, on the other hand, could scarce make his escape alone through a country hostile to Europeans while the many would send with the Belgian could be carefully selected with a view to preventing Whirper from persuading any considerable portion of his command to accompany him should he contemplate desertion of his chief. At last the Arab spoke, "'It is not necessary that we both return for the gold. You shall go north with the woman, carrying a letter to a friend of mine, who is always in touch with the best markets for such merchandise, while I return for the gold. We can meet again here when our business is concluded.' Whirper could scarce disguise the joy with which he received this welcome decision, and that he did entirely disguise it from the keen and suspicious eyes of Akmet Zak is open to question. However the decision reached the Arab and his lieutenant discussed the details of their forthcoming ventures for a short time further when Whirper made his excuses and returned to his own tent for the comforts and luxury of a long desired bath and shave.  In the catalogue of masculine pleasures there is scarce one which imparts a feeling of greater comfort and refreshment than follows a clean shave, and now with weariness temporarily banished, Albert Whirper sprawled in his rickety chair to enjoy a final cigarette before retiring. His thumbs tucked in his belt in lazy support of the weight of his arms touched the belt which held the jewel pouch about his waist. He tingled with excitement as he let his mind dwell upon the value of the treasure which, unknown to all, save himself, lay hidden beneath his clothing. What would Ochmek Zech say if he knew, Whirper grinned, how the old rascal's eyes would pop, could he but have a glimpse of those scintillating beauties. Whirper had never yet had an opportunity to feast his eyes for any great length of time upon them. He had not even counted them, only roughly had he guessed at their value. He unvastened the belt and drew the pouch from its hiding place. He was alone. The balance of the camp, save the centuries, had retired. None would enter the Belgian's tent. He fingered the pouch, feeling out the shapes and sizes of the precious little nodules within. He hefted the bag first in one palm, then in the other, and at last he wheeled his chair slowly around before the table, and in the rays of his small lamp let the glittering gems roll out upon the rough wood. The refulgent rays transformed the interior of the soiled and squalid canvas to the splendor of a palace in the eyes of the dreaming man. He saw the gilded halls of pleasure that would open their portals to the possessor of the wealth which lay scattered upon this stained and dented tabletop. He dreamed of joys and luxuries and power which always had been beyond his grasp, and as he dreamed his gaze lifted from the table, as the gaze of a dreamer will, to a far distant goal above the mean horizon of terrestrial common-placeness. Unseeing his eyes rested upon the shaving mirror which still hung upon the tent wall above the table, but his sight was focused far beyond, and then a reflection moved within the polished surface of the tiny glass. The man's eye shot back out of space to the mirror's face, and in it he saw reflected the grim visage of och-mant-zek, framed in the flaps of the tent doorway behind him. Werper stifled a gasp of dismay. With rare self-possession he let his gaze drop, without appearing to have halted upon the mirror until it rested again upon the gems. Without haste he replaced them in the pouch, tucked the latter into his shirt, selected a cigarette from his case, lighted it, and rose. Yawning and stretching his arms above his head, he turned slowly toward the opposite end of the tent. The face of och-mant-zek had disappeared from the opening. To say that Albert Werper was terrified would be putting it mildly. He realized that he not only had sacrificed his treasure, but his life as well. Och-mant-zek would never permit the wealth that he had discovered to slip through his fingers, nor would he forgive the duplicity of a lieutenant who had gained possession of such a treasure without offering to share it with his chief. Slowly the Belgian prepared for bed. If he were being watched he could not know. But if so the watcher saw no indication of the nervous excitement which the Europeans strove to conceal. When ready for his blankets the man crossed to the little table and extinguished the light. It was two hours later that the flaps at the front of the tent separated silently and gave entrance to a dark-robed figure which passed noiselessly from the darkness without to the darkness within. Cautiously the prowler crossed the interior. In one hand was a long knife. He came at last to the pile of blankets spread upon several rugs close to one of the tent walls. Lightly his fingers sought and found the bolt beneath the blankets, the bolt that should be Albert Werper. They traced out the figure of a man. And then an arm shot upward, poised for an instant, and descended again and again at rows and fell, and each time the long blade of the knife buried itself in the thing beneath the blankets. But there was an initial lifelessness in the silent bolt that gave the assassin momentary wonder. Feverishly he threw back the coverlets and searched with nervous hands for the pouch of jewels which he expected to find concealed upon his victim's body. An instant later he rose with a curse upon his lips. It was Ochmecht Zeck, and he cursed because he had discovered beneath the blankets of his lieutenant only a pile of discarded clothing arranged in the form and semblance of a sleeping man. Albert Werper had fled. Out into the village ran the chief calling in angry tomes to the sleepy Arabs who tumbled from their tents in answer to his voice, but though they searched the village again and again they found no trace of the Belgian. Foaming with anger, Ochmecht Zeck called his followers to horse, and though the night was pitchy black, they set out to scour the adjoining forest for their quarry. As they galloped from the open gates, Mugambi, hiding in a nearby bush, slipped unseen within the palisade. A score of blacks crowded about the entrance to watch the searchers depart, and as the last of them passed out of the village the blacks seized the portals and drew them too, and Mugambi lent a hand in the work as though the best of his life had been spent among the raiders. In the darkness he passed unchallenged as one of their number, and as they returned from the gates to their respective tents and huts, Mugambi melted into the shadows and disappeared. For an hour he crept about in the rear of the various huts and tents in an effort to locate that in which his master's mate was imprisoned, one there was which he was reasonably assured contained her, for it was the only hut before the door of which a sentry had been posted. Mugambi was crouching in the shadow of this structure just around the corner from the unsuspecting guard when another approached to relieve his comrade. The prisoner is safe within, asked the newcomer. She is, replied the other, for none has passed this doorway since I came. The new sentry squatted beside the door while he whom he had relieved made his way to his own hut. Mugambi slung closer to the corner of the building. In one powerful hand he gripped a heavy knob-stick. No sign of elation disturbed his phlegmatic calm, yet inwardly he was aroused to joy by the proof he had just heard that lady really was within. The sentry's back was toward the corner of the hut which hid the giant black. The fellow did not see the huge form which silently loomed behind him. The knob-stick swung upward in a curve and downward again. There was the sound of a dull thud, the crushing of heavy bone, and the sentry slumped into a silent inanimate lump of clay. A moment later Mugambi was searching the interior of the hut, at first slowly calling Lady in a low whisper, and finally with almost frantic haste until the truth presently dawned upon him, the hut was empty. End of Chapter 10 Chapter 11 of Tarzan and the Jewels of Opar This Librivox recording is in the public domain. Tarzan and the Jewels of Opar by Edgar Rice Burrows Chapter 11 Tarzan Becomes a Beast Again For a moment Werper had stood above this sleeping ape-man, his murderous knife poised for the fatal thrust, but fear stayed his hand. What if the first blow should fail to drive the point to his victim's heart? Werper shuddered in contemplation of the disastrous consequences to himself. Awakened, and even with a few moments of life remaining, the giant could literally tear his assailant to pieces should he choose, and the Belgian had no doubt but that Tarzan would so choose. Again came the soft sound of padded footsteps in the reeds, closer this time. Werper abandoned his design. Before him stretched the wide plain and escape, the Jewels were in his possession. To remain longer was to risk death at the hands of Tarzan or the jaws of the hunter creeping ever nearer. Turning he slunk away through the night toward the distant forest. Tarzan slept on. Where were those uncanny guardian powers that had formally rendered him immune from the dangers of surprise? Could this dull sleeper be the alert, sensitive Tarzan of old? Perhaps the blow upon his head had numbed his senses temporarily. Who may say? Closer crept the stealthy creature through the reeds. The rustling curtain of vegetation parted a few paces from where the sleeper lay, and the massive head of a lion appeared. The beast surveyed the eight-man intently for a moment. Then he crouched, his hind feet drawn well beneath him, his tail lashing from side to side. It was the beating of the beast's tail against the reeds which awakened Tarzan. Jungle folk do not awaken slowly. Instantly full consciousness and full command of their every faculty returns to them from the depth of profound slumber. Even as Tarzan opened his eyes he was upon his feet, his spear grasped firmly in his hand and ready for attack. Again was he Tarzan of the apes, sentient, vigilant, ready. No two lions have identical characteristics, nor does the same lion invariably act similarly under, like, circumstances. Whether it was surprise, fear, or caution which prompted the lion crouching ready to spring upon the man is immaterial. The fact remains that he did not carry out his original design. He did not spring at the man at all, but instead wheeled and sprang back into the reeds as Tarzan arose and confronted him. The eight-man shrugged his broad shoulders and looked about for his companion. Warper was nowhere to be seen. At first Tarzan suspected that the man had been seized and dragged off by another lion, but upon examination of the ground he soon discovered that the Belgian had gone away alone, out into the plain. For a moment he was puzzled, but presently came to the conclusion that Warper had been frightened by the approach of the lion and had sneaked off in terror. A sneer touched Tarzan's lips as he pondered the man's act, the desertion of a comrade in time of danger, and without warning. Well, if that was the sort of creature Warper was, Tarzan wished nothing more of him. He had gone and for all the eight-man carried he might remain away, Tarzan would not search for him. A hundred yards from where he stood grew a large tree, alone upon the edge of the reedy jungle. Tarzan made his way to it, clamored into it, and finding a comfortable crotch among its branches reposed himself for uninterrupted sleep until morning. And when morning came Tarzan slept on long after the sun had risen. His mind, reverted to the primitive, was untroubled by any more serious obligations than those of providing sustenance and safeguarding his life. Therefore there was nothing to awaken for until danger threatened, or the pangs of hunger assailed. It was the latter which he eventually aroused him.  Across the wasted meadowlands and fields of John Clayton, Lord Graystoke, Tarzan of the Apes looked, as a stranger upon the moving figures of Bessouli and his Braves, as they prepared their morning meal, and made ready to set out upon the expedition which Bessouli had planned after discovering the havoc and disaster which had befallen the estate of his dead master. The ape-man eyed the blacks with curiosity.  Yet he could not connect any of the various forms of life, animate and inanimate, which had fallen within the range of his vision since he had emerged from the darkness of the pits of Opar with any particular event of the past. Hazily he recalled a grim and hideous form, hairy, ferocious. A vague tenderness dominated his savage sentiments as this phantom memory struggled for recognition. His mind had reverted to his childhood days. It was the figure of the giant she-ape, Kayla, that he saw, but only half-recognized. He saw two other grotesque man-like forms. They were of turquoise, tubelat, kerchak, and a smaller, less ferocious figure that was Neta, the little playmate of his boyhood. Slowly, very slowly, as these visions of the past animated his lethargic memory, he came to recognize them. They took definite shape and form, adjusting themselves nicely to the various incidents of his life with which they had been intimately connected. His boyhood, among the apes, spread itself in a slow panorama before him, and as it unfolded, it induced within him a mighty longing for the companionship of the shaggy, low-browed brutes of his past. He watched the blacks scatter their cook-fire and depart, but though the face of each of them had but recently been as familiar to him as his own, they awakened within him no recollections whatsoever. When they had gone, he descended from the tree and sought food. Out upon the plain grazed numerous herds of wild ruminants.  No intricate process of reasoning caused him to circle widely until he was downwind from his prey. He acted instinctively. He took advantage of every form of cover as he crawled upon all fours and often flat upon his stomach toward them.  Again it was instinct which selected the former for his meat. A low bush grew but a few yards from the unsuspecting two. The eight-man reached its shelter. He gathered his spear firmly in his grasp. Cautiously he drew his feet beneath him. In a single swift move he rose and cast his heavy weapon at the mare's side, nor did he wait to note the effect of his assault, but leaped cat-like after his spear, his hunting-knife, in his hand. For an instant the two animals stood motionless. The tearing of the cruel barb into her side brought a sudden scream of pain and fright from the mare, and then they both wheeled and broke for safety. But Tarzan of the apes, for a distance of a few yards, could equal the speed of even these, and the first stride of the mare found her overhauled with a savage beast at her shoulder. She turned biting and kicking at her foe. Her mate hesitated for an instant, as though about to rush to her assistance, but a backward glance revealed to him the flying heels of the balance of the herd, and with a snort and a shake of his head he wheeled and dashed away. Clinging with one hand to the short mane of his quarry, Tarzan struck again and again with his knife at the unprotected heart the result had from the first been inevitable. The mare fought bravely, but hopelessly, and presently sank to the earth her heart pierced. The eight-man placed a foot upon her carcass and raised his voice in the victory call of the mangani. In the distance Basuli halted, as the faint notes of the hideous scream broke upon his ears. The great apes, he said to his companion. It has been long since I have heard them in the country of the Waziri. What could have brought them back? Tarzan grasped his kill and dragged it to the partial seclusion of the bush which had hidden his own near approach, and there he squattered upon it, cut a huge hunk of flesh from the loin, and proceeded to satisfy his hunger with the warm and dripping meat. Attracted by the shrill screams of the mare, a pair of hyenas slunk presently into view. They trotted to a point a few yards from the gorging eight-man and halted. Tarzan looked up, bared his fighting fangs, and growled. The hyenas returned the compliment and withdrew a couple of paces. They made no move to attack, but continued to sit at a respectful distance until Tarzan had concluded his meal. After the eight-man had cut a few strips from the carcass to carry with him he walked slowly off in the direction of the river to quench his thirst. His way lay directly toward the hyenas, nor did he alter his course because of them. With all the lordly majesty of Numa the lion he strode straight toward the growling beast. For a moment they held their ground bristling and defiant, but only for a moment, and then slunk away to one side while the indifferent eight-man passed them on his lordly way. A moment later they were tearing at the remains of the zebra. Back to the reeds went Tarzan and threw them toward the river. A herd of buffalo startled by his approach rose ready to charge or to fly. A great bull pawed the ground and bellowed as his bloodshot eyes discovered the intruder, but the eight-man passed across their front as though ignorant of their existence. The bull's bellowing lessened to a low rumbling. He turned and scraped a horde of flies from his side with his muzzle. Cast a final glance at the eight-man and resumed his feeding. His numerous family either followed his example or stood gazing after Tarzan in mild-eyed curiosity until the offset reeds swallowed him from view. At the river Tarzan drank his fill and bathed. During the heat of the day he lay up under the shade of a tree near the ruins of his burned barns. His eyes wandered out across the plain toward the forest and a longing for the pleasures of its mysterious depths possessed his thoughts for a considerable time. With the next sun he would cross the open and enter the forest. There was no hurry. There lay before him an endless vista of tomorrows, with not to fill them but the satisfying of the appetites and caprices of the moment. The eight-man's mind was untroubled by regret for the past or aspiration for the future.  Recalling only dimly any other existence, the eight-man was happy. Lord Graystoke had ceased to exist. For several hours Tarzan lulled upon his swaying leafy couch until once again hunger and thirst suggested an excursion. Stretching lazily he dropped to the ground and moved slowly toward the river. The game trail down which he walked had become by ages of use a deep, narrow trench. Its walls topped on either side by impenetrable thicket and dense growing trees, closely interwoven with thick-stemned creepers and lesser vines inextricably matted into two solid ram parts of vegetation. Tarzan had almost reached the point where the trail debounced upon the open river-bottom when he saw a family of lions approaching along the path from the direction of the river. The eight-man counted seven, a male and two lionesses, full grown, and four young lions as large and quite as formidable as their parents. Tarzan halted growling, and the lions paused, the great male in the lead bearing his fangs and rumbling forth a warning roar. In his hand the eight-man held his heavy spear, but he had no intention of pitting his puny weapon against seven lions. Yet he stood there growling and roaring, and the lions did likewise. It was purely an exhibition of jungle bluff. Each was trying to frighten off the other. Neither wished to turn back and give way, nor did either at first desire to precipitate an encounter. The lions were fed sufficiently so as not to be goaded by pangs of hunger, and as for Tarzan he seldom ate the meat of the carnivores. But a point of ethics was at stake, and neither side wished to back down. So they stood there facing one another, making all sorts of hideous noises the while they hurled jungle invecty back and forth. How long this bloodless duel would have persisted, it is difficult to say, though eventually Tarzan would have been forced to yield to superior numbers. There came, however, an interruption which put an end to the deadlock, and it came from Tarzan's rear. He and the lions had been making so much noise that neither could hear anything above their concerted bedlam, and so it was that Tarzan did not hear the great bolt bearing down upon him from behind until an instant before it was upon him, and then he turned to see Buto the rhinoceros, his little pig-eyes blazing, charging madly toward him, and already so close that escape seemed impossible. Yet so perfectly were mind and muscles coordinated in this unspoiled, primitive man that almost simultaneously, with the sense of perception of the threatened danger, he wheeled and hurled his spear at Buto's chest. It was a heavy spear shot with iron, and behind it were the giant muscles of the ape-man, while coming to meet it was the enormous weight of Buto and the momentum of his rapid rush. All that happened in the instant that Tarzan turned to meet the charge of the irascible rhinoceros might take long to tell, and yet would have taxed the swiftest lens to record. As his spear left his hand, the ape-man was looking down upon the mighty horn lured to toss him so close was Buto to him. The spear entered the rhinoceros' neck at its junction with the left shoulder, and passed almost entirely through the beast's body, and at the instant that he launched it Tarzan leaped straight into the air, alighting upon Buto's back, but escaping the mighty horn. Then Buto espied the lions, and bore madly down upon them, while Tarzan of the apes leaped nimbly into the tangled creepers at one side of the trail. The first lion met Buto's charge and was tossed high over the back of the maddened brute, torn and dying. And then the six remaining lions were upon the rhinoceros, rending and tearing the while they were being gored or trampled. From the safety of his perch Tarzan watched the royal battle with the keenest interest, for the more intelligent of the jungle folk are interested in such encounters. They are to them what the racetrack and the prize ring, the theater and the movies are to us. They see them often, but always they enjoy them, for no two are precisely alike. For a time it seemed to Tarzan that Buto the rhinoceros would prove victor in the gory battle. Already had he accounted for four of the seven lions and badly wounded the three remaining, when in a momentary lull in the encounter he sank limply to his knees and rolled over upon his side. Tarzan's spear had done its work. It was the man-made weapon which killed the great beast that might easily have survived the assault of seven mighty lions, for Tarzan's spear had pierced the great lungs and Buto with victory almost in sight succumbed to internal hemorrhage. Then Tarzan came down from his sanctuary, and as the wounded lions growling, dragged themselves away, the eight men cut his spear from the body of Buto, hacked off a stake, and vanished into the jungle. The episode was over. It had been all in the day's work, something which you and I might talk about for a lifetime. Tarzan dismissed from his mind the moment that the scene passed from his sight. Swinging back through the jungle in a wide circle, the eight men came to the river at another point, drank and took to the trees again, and while he hunted all oblivious of his past and careless of his future, there came through the dark jungles and the open park-like places and across the wide meadows, where grazed the countless herbivora of the mysterious continent, a weird and terrible caravan in search of him. There were fifty frightful men with hairy bodies and gnarled and crooked legs. They were armed with knives and great bludgeons, and at their head marched an almost naked woman, beautiful beyond compare. It was law of Opar, high priestess of the flaming god, and fifty of her horrid priests, searching for the perloiner of the sacred sacrificial knife. Never before had law passed beyond the crumbling outer walls of Opar, but never before had need been so insistent. The sacred knife was gone. Handed down through countless ages, it had come to her as a heritage and an insignia of her religious office and regal authority from some long dead progenitor of lost and forgotten Atlantis. The loss of the crown jewels or the great seal of England could have brought no greater consternation to a British king than did the pilfering of the sacred knife bring to law the Oparian queen and high priestess of the degraded remnants of the oldest civilization upon earth. When Atlantis, with all her mighty cities and her cultivated fields and her great commerce and culture and riches, sank into the sea long ages since, she took with her all but a handful of her colonists working the vast gold mines of Central Africa. From these and their degraded slaves and a later intermixture of the blood of the anthropoids sprung the gnarled men of Opar. But by some queer freak of fate, aided by natural selection, the old Atlantean strain had remained pure and undegraded in the females descended from a single princess of the royal house of Atlantis who had been in Opar at the time of the great catastrophe. Such was Law. Burning with white anger was the high priestess. Her heart has seething molten mass of hatred for Tarzan of the apes. The zeal of the religious fanatic whose altar has been desecrated was triply enhanced by the rage of a woman scorned. Twice had she thrown her heart at the feet of the godlike ape-man and twice had she been repulsed. Law knew that she was beautiful and she was beautiful, not by the standards of prehistoric Atlantis alone but by those of modern times was Law physically a creature of perfection. Before Tarzan came that first time to Opar, Law had never seen a human male other than the grotesque and knotted men of her clan. With one of these she must make sooner or later that the direct line of high priestesses might not be broken unless fate should bring other men to Opar. Before Tarzan came upon his first visit Law had had no thought that such men as he existed for she knew only her hideous little priests and the bulls of the tribe of great anthropoids that had dwelt from time immemorial in and about Opar until they had come to be looked upon almost as equals by the Oparians. Among the legends of Opar were tales of godlike men of the olden time and of black men who had come more recently but these latter had been enemies who killed and robbed and too these legends always held forth the hope that some day that nameless continent from which their race had sprung would rise once more out of the sea and with slaves that the long sweeps would send her carven gold-picked galleys forth to succor the long exiled colonists. The coming of Tarzan had aroused within Law's breast the wild hope that at last the fulfillment of this ancient prophecy was at hand, but more strongly still had it aroused the hot fires of love in a heart that never otherwise would have known the meaning of that all-consuming passion for such a wondrous creature as Law could never have felt love for any of the repulsive priests of Opar. Custom, duty, and religious zeal might have commanded the Union, but there could have been no love on Law's part. She had grown to young womanhood a cold and heartless creature, daughter of a thousand other cold heartless beautiful women who had never known love, and so when Love came to her it liberated all the pent passions of a thousand generations, transforming Law into a pulsing, throbbing volcano of desire, and with desire thwarted this great force of love and gentleness and sacrifice was transmuted by its own fires into one of hatred and revenge. It was in a state of mind super-induced by these conditions that Law led forth her jabbering company to retrieve the sacred emblem of her high office and wreak vengeance upon the author of her wrongs.  Of course he should be slain when captured, but his death would give Law no pleasure. She looked for that in the contemplated death agonies of Tarzan. He should be tortured. His should be a slow and frightful death. His punishment should be adequate to the immensity of his crime. He had rested the sacred knife from Law. He had lain sacrilegious hands upon the high priestess of the flaming God. He had desecrated the altar and the temple, for these things he should die. But he had scorned the love of Law, the woman, and for this he should die horribly with great anguish. The march of Law and her priests was not without its adventures. Unused were these to the ways of the jungle, since seldom did any venture forth from behind Opar's crumbling walls, yet their very numbers protected them, and so they came without fatalities far along the trail of Tarzan and Werper. Three great apes accompanied them, and to these was delegated the business of tracking the quarry, a feat beyond the senses of the Oparians. Law commanded. She arranged the order of March. She selected the camps. She set the hour for halting, and the hour for resuming, and though she was inexperienced in such matters, her native intelligence was so far above that of the men or the apes that she did better than they could have done. She was a hard taskmaster too, for she looked down with loathing and contempt upon the misshapen creatures amongst which cruel fate had thrown her, and to some extent vented upon them her dissatisfaction and her thwarted love. She made them build her a strong protection and shelter each night, and keep a great fire burning before it from dusk to dawn. When she tired of walking they were forced to carry her upon an improvised litter, nor did one dare to question her authority or her right to such services. In fact they did not question either. To them she was a goddess, and each loved her, and each hoped that he would be chosen as her mate. So they slayed for her, and bore the stinging lash of her displeasure and the habitually haughty disdain of her manner without a murmur. For many days they marched, the apes following the trail easily and going a little distance ahead of the body of the caravan, that they might warn the others of impending danger. It was during a noonday halt while all were lying resting after a tiresome march that one of the apes rose suddenly and sniffed the breeze. In a low guttural he cautioned the others to silence, and a moment later was swinging quietly upwind into the jungle. Law and the priests gathered silently together, the hideous little men fingering their knives and bludgeons, and awaited the return of the shaggy anthrapoid. Nor had they long to wait before they saw him emerge from a leafy thicket and approach them. Straight to law he came, and in the language of the great apes, which was also the language of decadent opar, he addressed her. The great tarmangani lies asleep there, he said, pointing in the direction from which he had just come. Come, and we can kill him. Do not kill him, commanded Law, in cold tomes. Bring the great tarmangani to me alive and unhurt, the vengeance is Law's. Go, but make no sound. And she waved her hands to include all her followers. Cautiously the weird party crept through the jungle in the wake of the great ape, until at last he halted them with a raised hand and pointed upward and a little ahead. There they saw the giant form of the ape-man stretched along a low bow, and even in sleep one hand grasped a stout limb, and one strong brown leg reached out and overlapped another, at ease lay Tarzan of the apes, sleeping heavily upon a full stomach and dreaming of Numa the lion, and Horta the boar, and other creatures of the jungle. No intimation of danger assailed the dormant faculties of the ape-man, he saw no crouching hairy figures upon the ground beneath him, nor the three apes that swung quietly into the tree beside him. The first intimation of danger that came to Tarzan was the impact of three bodies as the three apes leaped upon him and hurled him to the ground, where he alighted half stunned beneath their combined weight, and was immediately set upon by the fifty hairy men, or as many of them as good, swarm upon his person. Instantly the ape-man became the center of a whirling, striking, biting, maelstrom of horror. He fought nobly, but the odds against him were too great. Slowly they overcame him, though there was scarce one of them that did not feel the weight of his mighty fist or the rending of his fangs. Tarzan and the Jewels of Opar by Edgar Rice Burles CHAPTER XIII. CONDEMN TO TORTURE AND DEATH Law had followed her company, and when she saw them clawing and biting at Tarzan, she raised her voice and cautioned them not to kill him. She saw that he was weakening, and that soon the greater numbers would prevail over him, nor had she long to wait before the mighty jungle creature lay helpless and bound at her feet. Bring him to the place at which we stopped. She commanded, and they carried Tarzan back to the little clearing and threw him down beneath a tree. Build me a shelter, ordered Law. We shall stop here to-night, and to-morrow in the face of the flaming God Law will offer up the heart of this defiler of the temple. Where is the sacred knife? Who took it from him? But no one had seen it, and each was positive in his assurance that the sacrificial weapon had not been upon Tarzan's person when they captured him. The eight-man looked upon the menacing creatures which surrounded him and snarled his defiance. He looked upon Law and smiled. In the face of death he was unafraid. Where is the knife? Law asked him. I do not know, replied Tarzan. The man took it with him when he slipped away during the night.  Did you not hold me prisoner?  Of what good was your knife anyway? You can make another. Did you follow us all this way for nothing more than a knife?  Law laughed a bitter laugh, for in her heart she knew that Tarzan's sin was greater than the perloining of the sacrificial knife of Opar. Yet as she looked at him lying bound and helpless before her, tears rose to her eyes so that she had to turn away to hide them. But she remained inflexible in her determination to make him pay in frightful suffering and in eventual death for daring to spurn the love of Law. When the shelter was completed Law had Tarzan transferred to it. All night I shall torture him, she muttered to her priest, and at the first streak of dawn you may prepare the flaming altar upon which his heart shall be offered up to the flaming god. Gather wood well filled with pitch, lay it in the form and size of the altar at Opar, in the center of the clearing, that the flaming god may look down upon our handiwork and be pleased. During the balance of the day the priests of Opar were busy erecting an altar in the center of the clearing, and while they worked they chanted weird hymns in the ancient tongue of that lost continent that lies at the bottom of the Atlantic. They knew not the meanings of the words they mouthed, they but repeated the ritual that had been handed down from preceptor to neophyte since that long gone day when the ancestors of the Piltdown man still swung by their tails in the humid jungles that are England now, and in the shelter of the hut Law paced to and fro beside the stoic ape man, resigned to his fate was Tarzan, no hope of succor gleamed through the dead black of the death sentence hanging over him, he knew that his giant muscles could not part the many strands that bound his wrists and ankles, for he had strained often but ineffectually for release. He had no hope of outside help, and only enemies surrounded him within the camp, and yet he smiled at Law as she paced nervously back and forth the length of the shelter, and Law she fingered her knife and looked down upon her captive. She glared and muttered, but she did not strike. To-night, she thought, to-night when it is dark I will torture him. She looked upon his perfect god-like figure and upon his handsome smiling face, and then she steeled her heart again by thoughts of her love spurned, by religious thoughts that damned the infidel who had desecrated the holy of holies who had taken from the bloodstained altar of Opar the offering to the flaming god, and not once, but thrice, three times had Tarzan cheated the god of her fathers. At the thought Law paused and knelt at his side, in her hand was a sharp knife. She placed its point against the eight-man's side and pressed upon the hilt, but Tarzan only smiled and shrugged his shoulders. How beautiful he was! Law bent low over him, looking into his eyes. How perfect was his figure! She compared it with those of the knurled and knotted men from whom she must choose a mate, and Law shuddered at the thought. Dusk came, and after dusk came night. A great fire blazed within the little thorn-boma about the camp. The flames played upon the new altar erected in the center of the clearing, arousing in the mind of the high priestess of the flaming god a picture of the event of the coming dawn. She saw this giant and perfect form writhing amid the flames of the burning pyre. She saw those smiling lips burned and blackened, falling away from the strong, white teeth.  She saw these and many other frightful pictures, as she stood with closed eyes and clenched fists above the object of her hate. Ah, was it hate that Law of Opar felt!  Tarzan lay quietly in his bonds. He suffered from thirst and from the cutting of the tight strands about his wrists and ankles, but he made no complaint. A jungle beast was Tarzan with the stoicism of the beast and the intelligence of man. He knew that his doom was sealed, that no supplications would avail to temper the severity of his end, and so he wasted no breath in pleadings, but waited patiently in the firm conviction that his sufferings could not endure forever. In the darkness Law stooped above him. In her hand was a sharp knife and in her mind the determination to initiate his torture without further delay. The knife was pressed against his side, and Law's face was close to his, when a sudden burst of flame from new branches thrown upon the fire without lighted up the interior of the shelter. Close beneath her lips Law saw the perfect features of the forest god, and into her woman's heart welled all the great love she had felt for Tarzan since first she had seen him, and all the accumulated passion of the years that she had dreamed of him. Dagger in hand, Law, the high priestess, towered above the helpless creature that had dared to violate the sanctuary of her deity. There should be no torture. There should be instant death. No longer should the defiler of the temple pollute the sight of the Lord God Almighty, a single stroke of the heavy blade and then the corpse to the flaming pyre without. The knife arm stiffened, ready for the downward plunge, and then Law, the woman, collapsed weakly upon the body of the man she loved. She ran her hands in mute caress over his naked flesh.  She covered him with her body as though to protect him from the hideous fate she had ordained for him, and in trembling piteous tones she begged him for his love. For hours the frenzy of her passion possessed the burning handmaiden of the flaming god, until at last sleep overpowered her, and she lapsed into unconsciousness beside the man she had sworn to torture and to slay, and Tarzan untroubled by thoughts of the future, slept peacefully in Law's embrace. At the first hint of dawn the chanting of the priests of Opar brought Tarzan to wakefulness. Initiated in low and subdued tones the sound soon rose in volume to the open diapason of barbaric bloodlust. Lost her, her perfect arm pressed Tarzan closer to her.  "'Love me, Tarzan,' she cried, "'love me, and you shall be saved.' Tarzan's bonds hurt him. He was suffering the tortures of long restricted circulation. With an angry growl he rolled over with his back toward Law. That was her answer. The high priestess leaped to her feet.  "'Come, priests of the flaming God,' she cried, "'and make ready the sacrifice.' The warped things advanced and entered the shelter. They laid hands upon Tarzan, and bore him forth, and as they chanted they kept time with their crooked body, swaying too and fro to the rhythm of their song of blood and death. Behind them came Law, swaying too, but not in unison with the chanted cadence. White and drawn was the face of the high priestess, white and drawn with unrequited love and hideous terror of the moments to come. Yet stern in her resolve was Law. The infidels should die. The scorner of her love should pay the price upon the fiery altar. She saw them lay the perfect body there upon the rough branches. She saw the high priest, he to whom custom would unite her. Bent, crooked, gnarled, stunted, hideous, advanced with the flaming torch and stand awaiting her command to apply it to the faggots surrounding the sacrificial pyre. His hairy, bestial face was distorted in a yellow fanged grin of anticipatory enjoyment. His hands were cupped to receive the life-blood of the victim, the red nectar that at Opar would have filled the golden sacrificial goblets.  The high priest looked questioningly at order.  Tarzan closed his eyes and awaited the end. He knew that he would suffer, for he recalled the faint memories of past burns. He knew that he would suffer and die, but he did not flinch. Death is no great adventure to the jungle bread who walk hand in hand with the grim specter by day and lie down at his side by night through all the years of their lives. It is doubtful that the eight-man even speculated upon what came after death. As a matter of fact, as his end approached, his mind was occupied by thoughts of the pretty pebbles he had lost, yet his every faculty still was open to what passed around him. He felt Law lean over him and he opened his eyes. He saw her white, drawn face, and he saw tears blinding her eyes. Tarzan, my Tarzan! She moaned. Tell me that you love me, that you will return to Opar with me, and you shall live.  What is your answer? At the last moment the woman in law had triumphed over the high priestess of a cruel cult. She saw upon the altar the only creature that ever had roused the fires of love within her virgin breast. She saw the beast-faced fanatic who would one day be her mate unless she found another less repulsive, standing with the burning torch ready to ignite the pyre. Yet, with all her mad passion for the eight-man, she would give the word to apply the flame if Tarzan's final answer was unsatisfactory. With heaving bosom she leaned close above him. Yes, or no, she whispered. Through the jungle, out of the distance, came faintly a sound that brought a sudden light of hope to Tarzan's eyes. He raised his voice in a weird scream that sent law back from him a step or two. The impatient priest grumbled, and switched the torch from one hand to the other at the same time holding it closer to the tinder at the base of the pyre. Your answer, insisted Law. What is your answer to the love of Law of Opar? Closer came the sound that had attracted Tarzan's attention, and now the others heard it, the shrill trumpeting of an elephant. As Law looked wide-eyed into Tarzan's face, there to read her fate for happiness or heartbreak, she saw an expression of concern shadow his features. Now, for the first time she guessed the meaning of Tarzan's shrill scream, he had summoned Tantor, the elephant, to his rescue. Law's brows contracted in a savage scowl.  She cried. Then die! The torch! She commanded, turning toward the priest. Tarzan looked up into her face. Tantor is coming, he said. I thought that he would rescue me, but I know now from his voice that he will slay me and you and all that fall in his path, searching out with the cunning of Sheeta, the Panther, those who would hide from him, for Tantor is mad with the madness of love. Law knew only too well the insane ferocity of a bull-elephant in must. She knew that Tarzan had not exaggerated. She knew that the devil in the cunning, cruel brain of the great beast might send it hither and thither hunting through the forest for those who escaped its first charge, or the beast might pass on without returning. No one might guess which. I cannot love you, Law," said Tarzan in a low voice. I do not know why, for you are very beautiful. I could not go back and live in Opar. I, who have the whole broad jungle for my range. No, I cannot love you, but I cannot see you die beneath the goring tusks of mad Tantor. Cut my bonds before it is too late. Already he is almost upon us. Cut them, and I may yet save you. A little spiral of curling smoke rose from one corner of the pyre, the flames licked upward, crackling. Law stood there like a beautiful statue of despair gazing at Tarzan and at the spreading flames. In a moment they would reach out and grasp him. From the tangled forest came the sound of cracking limbs and crashing trunks. Tantor was coming down upon them, a huge juggernaut of the jungle. The priests were becoming uneasy. They cast apprehensive glances in the direction of the approaching elephant and then back at Law. Fly! she commanded them, and then she stooped and cut the bonds securing her prisoner's feet and hands. In an instant Tarzan was upon the ground. The priests screamed out their rage and disappointment. He, with the torch, took a menacing step toward Law and the ape man. Traitor! he shrieked at the woman. For this you shall die! raising his bludgeon he rushed upon the High Priestess. But Tarzan was there before her. Leaping in to close quarters the ape man seized the upraised weapon and rinsed it from the hands of the frenzied fanatic, and then the priest closed upon him with tooth and nail. Seizing the stocky, stunted body and his mighty hands, Tarzan raised the creature high above his head, hurling him at his fellows who were now gathered ready to bear down upon their erstwhile captive. Law stood proudly with ready knife behind the ape man. No faint sign of fear marked her perfect brow, only haughty disdain for her priests, and admiration for the man she loved so hopelessly filled her thoughts.  The priest stood for an instant paralyzed with terror, but Tarzan turned and gathering Law in his arms raced for the nearest tree. Tantor bore down upon him trumpeting shrilly. Law clung with both white arms about the ape man's neck. She felt him leap into the air and marvel at his strength and his ability. As burdened with her weight he swung nimbly into the lower branches of a large tree and quickly bore her upward beyond reach of the sinuous trunk of the Pakaderm. Momentarily baffled here, the huge elephant wheeled and bore down upon the hapless priest who had now scattered terror-stricken in every direction, the nearest he gored and threw high among the branches of a tree. One he seized in the coils of his trunk and broke upon a huge bowl, dropping the mangled pulp to charge trumpeting after another. Two he trampled beneath his huge feet, and by then the others had disappeared into the jungle. Now Tantor turned his attention once more to Tarzan for one of the symptoms of madness is a revulsion of affection. Objects of sane love become the objects of insane hatred. Peculiar in the unwritten annals of the jungle was the proverbial love that had existed between the eight man and the tribe of Tantor. No elephant in all the jungle would harm the tar-mangani, the white ape, but with the madness of must upon him the great bull sought to destroy his long-time play-fellow. Back to the tree where Law and Tarzan Perts came Tantor the elephant, he reared up with his forefeet against the bowl and reached high toward them with his long trunk, but Tarzan had foreseen this, and clamored beyond the bowl's longest reach, failure but tended to further enrage the mad creature. He bellowed and trumpeted and screamed until the earth shook to the mighty volume of his noise. He put his head against the tree and pushed, and the tree bent before his mighty strength, yet still it held. The actions of Tarzan were peculiar in the extreme. Had Numa, or Sabor, or Sheeta, or any other beast of the jungle been seeking to destroy him, the eight man would have danced about hurling missiles and invectives at his assailant. He would have insulted and taunted them, reviling in the jungle billings gate he knew so well. But now he sat silent out of Tantor's reach, and upon his handsome face was an expression of deep sorrow and pity, for of all the jungle folk Tarzan loved Tantor the best. Could he have slain him? He would not have thought of doing so. His one idea was to escape, for he knew that with the passing of the must Tantor would be sane again, and that once more he might stretch at full length upon that mighty back and make fully speech into those great flapping ears. Finding that the tree would not fall to his pushing, Tantor was but enraged the more. He looked up at the two perched high above him, his red rimmed eyes blazing with insane hatred, and then he wound his trunk about the bowl of the tree, spread his giant feet wide apart, and tugged to uproot the jungle giant. A huge creature was Tantor, an enormous bowl in the full prime of all his stupendous strength. Mightily he strove until presently, to Tarzan's consternation, the great tree gave slowly at the roots. The ground rose in little mounds and ridges about the base of the bowl. The tree tilted. In another moment it would be uprooted and fall. The eight-man whirled law to his back, and just as the tree inclined slowly in its first movement out of the perpendicular, before the sudden rush of its final collapse, he swung to the branches of a lesser neighbor. It was a long and perilous leap. Law closed her eyes and shuddered, but when she opened them again she found herself safe, and Tarzan whirling onward through the forest. Behind them the uprooted tree crashed heavily to the ground, carrying with it the lesser trees in its path and then Tantor, realizing that his prey had escaped him, set up once more his hideous trumpeting, and followed at a rapid charge upon their trail. CHAPTER XIV. A priestess, but yet a woman. At first law closed her eyes and clung to Tarzan in terror, though she made no outcry, but presently she gained sufficient courage to look about her, to look down at the ground beneath, and even to keep her eyes open during the wide perilous swings from tree to tree, and then there came over her a sense of safety because of her confidence in the perfect physical creature in whose strength and nerve and agility her fate lay. Once she raised her eyes to the burning sun and murmured a prayer of thanks to her pagan god that she had not been permitted to destroy this god-like man, and her long lashes were wet with tears. A strange anomaly was law of Opar, a creature of circumstance torn by conflicting emotions, now the cruel and bloodthirsty creature of a heartless god, and again a melting woman filled with compassion and tenderness, sometimes the incarnation of jealousy and revenge, and sometimes a sobbing maiden, generous and forgiving, at once a virgin and a wanton, but always a woman. Such was law. She pressed her cheek close to Tarzan's shoulder, slowly she turned her head until her hot lips were pressed against his flesh, she loved him and would gladly have died for him, yet within an hour she had been ready to plunge a knife into his heart and might again within the coming hour. A hapless priest seeking shelter in the jungle, chance to show himself to enraged Tantor, the great beast turned one side, bore down upon the crooked little man, snuffed him out and then diverted from his course, blundered away toward the south. In a few minutes even the noise of his trumpeting was lost in the distance. Tarzan dropped to the ground and law slipped to her feet from his back. "'Call your people together,' said Tarzan.  "'They will not kill you,' contradicted the ape-man. "'No one will kill you while Tarzan of the apes is here. "'Call them, and we will talk with them.' Law raised her voice in a weird, flute-like call that carried far into the jungle on every side. From near and far came answering shouts in the barking tones of the Oparian priests. "'We come! We come!' Again and again law repeated her summons until singly and in pairs the greater portion of her following approach and halted a short distance away from the high priestess and her saviour. They came with scowling brows and threatening mean. When all had come Tarzan addressed them. "'Your law is safe,' said the ape-man. "'Had she slain me, she would now herself be dead, and many more of you. But she spared me that I might save her. Go your way with her back to Opar, and Tarzan will go his way into the jungle. Let there be peace always between Tarzan and law. What is your answer?' The priests grumbled and shook their heads. They spoke together, and law and Tarzan could see that they were not favourably inclined toward the proposition. They did not wish to take law back, and they did wish to complete the sacrifice of Tarzan to the flaming god. At last the ape-man became impatient. "'You will obey the commands of your queen,' he said, and go back to Opar with her, or Tarzan of the apes will call together the other creatures of the jungle and slay you all. Law saved me that I might save you and her. I have served you better alive than I could have dead. If you are not all fools, you will let me go my way in peace and you will return to Opar with law. I know not where the sacred knife is, but you can fashion another. Had I not taken it from law you would have slain me, and now your god must be glad that I took it since I have saved his priestess from love mad tantor. Will you go back to Opar with law, promising that no harm shall befall her?' The priests gathered together in a little knot, arguing and discussing. They pounded upon their breasts with their fists. They raised their hands and eyes to their fiery god. They growled and barked among themselves, until it became evident to Tarzan that one of their number was preventing the acceptance of his proposal. This was the high priest whose heart was filled with jealous rage because law openly acknowledged her love for the stranger, when by the worldly customs of their cult she should have belonged to him. Seemingly there was to be no solution of the problem until another priest stepped forth and raising his hand a dressed law. Cage, the high priest, he announced, would sacrifice you both to the flaming god. But all of us except Cage would gladly return to Opar with our queen. You are many against one, spoke up Tarzan. Why should you not have your will? Go your way with law to Opar, and if Cage interferes, slay him. The priests of Opar welcomed this suggestion with loud cries of approval. To them it appeared nothing short of divine inspiration. The influence of ages of unquestioning obedience to high priests had made it seem impossible to them to question his authority, but when they realized that they could force him to their will, they were as happy as children with new toys. They rushed forward and seized Cage. They talked in loud menacing tones into his ear. They threatened him with bludgeon and knife, until at last he acquiesced in their demands, though sullenly, and then Tarzan stepped close before Cage. Priest, he said. Law goes back to her temple under the protection of her priests, and the threat of Tarzan of the apes that whoever harms her shall die. Tarzan will go again to Opar before the next reigns, and if harm has befallen law, woe betide Cage the high priest. Sullenly Cage promised not to harm his queen. Protect her, cried Tarzan to the other Oparians. Protect her so that when Tarzan comes again he will find law there to greet him. Law will be there to greet thee, exclaimed the high priestess, and law will wait, longing, always longing, until you come again. Oh, tell me that you will come. Who knows, asked the ape-man, as he swung quickly into the trees and raced off toward the east. For a moment law stood looking after him. Then her head drooped. A sigh escaped her lips, and like an old woman she took up the march toward distant Opar. Through the trees raced Tarzan of the apes until the darkness of night had settled upon the jungle. Then he lay down and slept, with no thought beyond the morrow and with even law but the shadow of a memory within his consciousness. But a few marches to the north Lady Greystoke looked forward to the day when her mighty lord and master should discover the crime of Ochmet Zek and be speeding to rescue and avenge, and even as she pictured the coming of John Clayton, the object of her thoughts squatted, almost naked, beside a fallen log, beneath which he was searching with grimy fingers for a chanced beetle or a luscious grub. Two days elapsed following the theft of the jewels before Tarzan gave them a thought. Then, as they chanced to enter his mind, he conceived a desire to play with them again, and having nothing better to do than satisfy the first whim which possessed him, he rose and started across the plain from the forest in which he had spent the preceding day. Though no mark showed where the gems had been buried, and though the spot resembled the balance of an unbroken stretch several miles in length where the reeds terminated at the edge of the meadowland, yet the ape-man moved with unerring precision directly to the place where he had hid his treasure. With his hunting-knife he upturned the loose earth, beneath which the pouch should be. But though he excavated to a greater distance than the depth of the original hole, there was no sign of pouch or jewels. Tarzan's brow clouded as he discovered that he had been despoiled. Little or no reasoning was required to convince him of the identity of the guilty party, and with the same celerity that had marked his decision to unearth the jewels, he set out upon the trail of the thief. Though the spore was two days old and practically obliterated in many places, Tarzan followed it with comparative ease. A white man could not have followed it twenty paces, twelve hours after it had been made. A black man would have lost it within the first mile, but Tarzan of the apes had been forced in childhood to develop senses that an ordinary mortal scarce ever uses. We may note that garlic and whiskey on the breath of a fellow strap-hanger, or the cheap perfume emanating from the person of the wondrous lady sitting in front of us, and deplore the fact of our sensitive noses, but as a matter of fact we cannot smell at all. Our olfactory organs are practically atrophied by comparison with the development of the sense among the beasts of the wild, where a foot is placed and a fluvium remains for a considerable time. It is beyond the range of our sensibilities, but to a creature of the lore orders, especially to the hunters and the hunted, as interesting and off times more lucid than is the printed page to us. Nor was Tarzan dependent alone upon his sense of smell, vision and hearing had been brought to a marvellous state of development by the necessities of his early life, where survival itself depended almost daily upon the exercise of the keenest vigilance and the constant use of all his faculties. And so he followed the old trail of the Belgian through the forest and toward the north, but because of the age of the trail he was constrained to a far from rapid progress. The man he followed was two days ahead of him when Tarzan took up the pursuit and each day he gained upon the eight man. The latter, however, felt not the slightest doubt as to the outcome. Someday he would overhaul his query. He could buy his time in peace until that day dawned. Doggedly he followed the faint spore, pausing by day only to kill and eat, and at night only to sleep and refresh himself. Occasionally he passed parties of savage warriors, but these he gave a wide berth, for he was hunting with a purpose that was not to be distracted by the minor accidents of the trail. These parties were of the collecting hordes of the Waziri and their allies which Besouli had scattered his messenger's broadcast to summon. They were marching to a common rendezvous in preparation for an assault upon the stronghold of Akmet Zek, but to Tarzan they were enemies. He retained no conscious memory of any friendship for the black man. It was night when he halted outside the palisaded village of the Arab raider. Perched in the branches of a great tree he gazed down upon the life within the enclosure. To this place had the spore led him. His query must be within. But how was he to find him among so many huts? Tarzan, although cognizant of his mighty powers, realized also his limitations. He knew that he could not successively cope with great numbers in open battle. He must resort to the stealth and trickery of the wild beast if he were to succeed. Sitting in the safety of his tree, munching upon the leg bone of Horta the boar, Tarzan waited a favorable opportunity to enter the village. For a while he nod at the bulging round ends of the large bone, splintering off small pieces between his strong jaws and sucking at the delicious marrow within. But all the time he cast repeated glances into the village. He saw white-robed figures and half-naked blacks, but not once did he see one who resembled the stealer of the gems. Patently he waited until the streets were deserted by all save the sentries at the gates. Then he dropped lightly to the ground, circled to the opposite side of the village and approached the palisade. At his side hung a long rawhide rope, a natural and more dependable evolution from the grass-rope of his childhood. Loosening this he spread the noose upon the ground behind him, and with a quick movement of his wrist tossed the coils over one of the sharpened projections of the summit of the palisade. Drawing the noose taut he tested the solidity of its hold. Satisfied, the eight man ran nimbly up the vertical wall, aided by the rope which he clutched in both hands. Once at the top it required but a moment to gather the dangling rope once more into its coils, make it fast again at his waist, take a quick glance downward within the palisade, and assured that no one lurked directly beneath him, dropped softly to the ground. Now he was within the village, before him stretched a series of tents and native huts, the business of exploring each of them would be fraught with danger, but danger was only a natural factor of each day's life. It never appalled Tarzan. The chances appealed to him, the chances of life and death with his prowess and his faculties pitted against those of a worthy antagonist. It was not necessary that he enter each habitation through a door, a window, or an open shink. His nose told him whether or not his prey lay within. For some time he found one disappointment following upon the heels of another in quick succession. No spore of the Belgian was discernable, but at last he came to a tent where the smell of the thief was strong. Tarzan listened, his ear close to the canvas at the rear, but no sound came from within. At last he cut one of the pin-ropes, raised the bottom of the canvas, and intruded his head within the interior. All was quiet and dark. Tarzan crawled cautiously within. The scent of the Belgian was strong, but it was not live scent. Even before he had examined the interior minutely, Tarzan knew that no one was within it. In one corner he found a pile of blankets and clothing scattered about, but no pouch of pretty pebbles. A careful examination of the balance of the tent revealed nothing more, at least nothing to indicate the presence of the jewels. But at the side where the blankets and clothing lay, the eight men discovered that the tent wall had been loosened at the bottom, and presently he sensed that the Belgian had recently passed out of the tent by this avenue. Tarzan was not long in following the way that his prey had fled. The spore led always in the shadow and at the rear of the huts and tents of the village. It was quite evident to Tarzan that the Belgian had gone alone and secretly upon his mission. Evidently he feared the inhabitants of the village, or at least his work had been of such a nature that he dared not risk detection. At the back of a native hut the spore led through a small hole recently cut in the brush wall and into the dark interior beyond. Fearlessly Tarzan followed the trail. On hands and knees he crawled through the small aperture. Within the hut his nostrils were assailed by many odors, but clear and distinct among them was one that half aroused a latent memory of the past. It was the faint and delicate odor of a woman. With the cognizance of it arose in the breast of the eight men a strange uneasiness, the result of an irresistible force which he was destined to become acquainted with anew, the instinct which draws the male to his mate. In the same hut was the sense spore of the Belgian too, and as both these assailed the nostrils of the eight men, mingling one with the other, a jealous rage leaped and burned within him, though his memory held before the mirror of recollection no image of the she to which he had attached his desire. Like the tent he had investigated the hut too was empty, and after satisfying himself that his stolen pouch was secreted nowhere within he left as he had entered by the hole in the rear wall. Here he took up the spore of the Belgian, followed it across the clearing over the palisade and out into the dark jungle beyond. End of Chapter 14


Recording office hours. We're talking about Hindley-Milner type inference and specifically in the case here Where we have two apply statements and we have the same function on the left E and has some parameter on the right here So let's just say Let's give these abstract names. We've never seen before. This is C and this is D, right? So we know from each we know let's say not even looking at this one looking at this apply statement We know E has the type Where it's a function, so it's definitely a function, right? And it takes in some type So it takes in some One parameter, so it takes in a type of C and it returns Let's just say this is T1 whatever that type of that apply statement is so it takes in a TC and returns a T1 Then we go over here to this apply statement, right? We see the same thing. So we see okay, so first thing right So the constraints all so the constraints are always valid have to always be satisfied So this is always going to happen. This is going to be an equality that holds throughout the entire tree Or else we have a type error For instance, so if we had something else like let's say We had something else over here. It was a bracket operator and that had something F and E so we're applying the bracket operator on the Array on the F, which would mean F would have to be an array, but what was E right here? Yeah, it has to be an integer to be used here, right? So that's a constraint here So the question is is an integer a function that takes in a Function that takes in the type TC And returns a type T1 If what You mean that Oh E E is a function that takes in a type TC and returns a type T1 But does that does that work or does it have can it not be a function? So what's the constraint here? So let's just put arbitrary types here. So we have type Let's say T1 T2 and T3 Right arbitrary types not even looking the only node. We're looking at is this node here Right, so what do we know about the types just looking at this statement? So I'm gonna erase these I don't know I don't know any of their types But I know I know something this node to the constraints about this node and the semantics here the types Tell me something about how these types are all related T2 is an array T2 is an array Of T1 yep, right T3 is an integer And these have to hold right if the type of T3 is not an integer This doesn't type check so just to double check So let's get in there's like so Okay So then we look at what it is right What I have F and E here right and so now I have the constraints when I look at each of these nodes I say oh, I have the constraint T3 is equal to the type of E and Let's see T2 is equal to the type of F Right these constraints hold everywhere So if earlier I Had said the type of E is something that it's a function that takes in so let's let's think about like this Let's get rid of functions. Let's say earlier. We said we we have the constraint that T E is an array the type of E is an array of It's so Question is with this T E is an array of it's can T E be equal to an integer or those types the same No, it doesn't make sense right one is an array of integers Yeah, the other one's just an in single integer right those are completely different types Right, so therefore that would not type check Your team does that do anything? I think it's still working. I guess I can ruin the flow of everything in tests, but yeah Allegedly, okay So so yeah, so this is kind of comes down to remember when we talked about like structural equality of types Right, so like it's really easy to do is an integer a Boolean Definitely not is an integer an Array of integers No, can't be right. It doesn't make sense You can't use an integer when you have an array because the whole point is an array is multiple type Multiple elements all of the same type and you use the array Array index operator to select one of them so you think of the This operator gets rid of this part as opposed to the types, right? Okay Okay, so then we have kind of the question so let's say we have a function that takes in type t1 Returns some type t2 and We want to say well is that equal to a function that takes in type t1 comma t2 and returns a t3 So what does this mean? It's a function how many parameters does function have And what is it typed as a return? Okay, this function what is this? Yeah, this function returns two parameters takes in two parameters one of type t1 one of type t2 and returns a parameter of type t return something of type t3 so Are these equal? No, you can't any places the thing about is it equals any place you could use this could you use this instead? Well, actually, okay, so that's a good question No, so definitely Definitely not yet Right because this function takes two parameters and this one takes one So you definitely can never use those in different instances, right? It doesn't make sense So this is definitely not equal Right so then So if we go back to your question here Or if t3 we see that instead of it being an array of it So Well based off we said it can't look a function exactly. Yeah, so if I have an integer And I say well, is it the same thing as something that takes in t1 and returns an integer a function that takes in t1 returns an integer No, you can't use a function in Place of an integer, right? It doesn't make sense You have to call this function in order to get the return type, right? That's how you use that if you'd use the apply operator pass in something of type t1 and you get an integer that you could then use But just using that function by itself Man that definitely doesn't type check So even though the return type of that function is integer you can't say it's equal to integer, right? I still have to operate on that function. Exactly that function Exactly, they're not structurally equivalent, right? So on one side you have a base type of an it and on the right side you have a function that takes in t1 returns an integer Okay, some other wrinkles here. Let's say we have like t1 returns type t2 and then we have I don't know t3 returns type t4, right? so we have this constraint so So what does this mean? It could be yeah, exactly, but this gives us additional constraints, right? So we know they're both functions and we know they both have the same types Right, so this means that in order for this equality to hold Was t1 have to equal t3 and was t2 have to equal t4 exactly Just like if you get in a situation where you have let's say an array of Type t5 and you have the constraint that that's equal to an array of Booleans. That's our favorite word Right, so is this equal? Maybe but it also gives us another constraint, right? Because we know okay structurally on the outside of the same they're both arrays so that matches so they definitely don't it's not Not equal right away, but then I have the additional constraint that t5 is a Boolean And that constraint must hold so for this to hold that means this holds And that's got to hold everywhere throughout the program. So if you ever see t5 not be a Boolean Then that's a problem Doesn't matter honestly Yeah, I mean I like to just do it top-down because that's more natural to me But that's like the nice really nice thing about this is you can do it in any order And as you're going through as long as you apply these constraints just like we did here, right? That's t3 is an integer and t2 is an array of type t1 as long as you do that everywhere It'll work out the same so in a homework problem if it asks for the type of a function, but the parse tree doesn't type check You type error Have any other homework three questions ABC and B is a function, but it's also a use later by itself Right, so it's just basically just like so It's got to be have the same type everywhere so if it's So for instance like here here's actually a really good example Like this example Scoot in a little bit. I am recording by the way So here you have function application. We're applying e We have e as a function that's being called So this would be some somewhere we have ec like this and then this here we have something like f bracket e Right and the dot dots dots here. It doesn't matter where this other piece is it could be anywhere, right? Doesn't matter so when we see so let's give each of let's give this a type t1 and So when we look at this apply this apply has constraints right function calls have constraints. So what What do we know about the types? Let's say t e tc and t1 here Return an integer why just did this Well, what does e have to be in order to for this to work Yeah, it's got to be a function and How many parameters does that function have? What what's the type of that parameter? Exactly we have tc and what does that function return? Something but we've given it a name here, right? Yeah, so whatever because this node is going to have some type and if the type so if I said x is equal to E bracket c right or e calling function e passing a parameter c assign that to parameter x So whatever the type of this is right if we're using this to check or whatever if this is an if statement Right, so we have the constraint that e better be a function that takes in one parameter Whose type is tc and that returns something of type t1? That's what you know, so we know right here e Has got to be a function. It's got to be a function that takes in one type c It takes in one parameter that's type is tc and that returns some other type t1 Now we get to this So let's give this a name t2 Just this node and then we have tf and te so we have t2 Okay, so looking at this node what constraints do we have here and what about tf of what? Yeah, because that's what we're gonna return here So the same thing right this is going to return something right because when you access when you access an array element, right? you want to you're essentially Peeling off this array of layer and returning one of those elements, and so if you have an array of Booleans When you index into one you're gonna return a Boolean right, but we don't have any constraints on what that type is We don't know these may be defined t2. Maybe Have a constraint somewhere else Okay, so the question is We have this So can an integer ever be a function? No if we have a similar situation Well, what kind of error is it? Yeah, a type check error exactly. So yeah, you have a type error So you say you say here well you could explain a little bit you say here e is being used as an integer So we have the constraint that e has to be an integer, but here e is being used as a function Therefore, there's no possible way that these things type check this this program does not type check It doesn't matter whatever else happens in any of this tree if we get one case like that we say boom type error Yeah, can't possibly be valid Yeah Let's have project questions. Yes First I think I'm gonna stop recording now
