Following the scent spoor that was his only guide, Tarzan of the Apes moved rapidly through the trees. At first he climbed high to the upper terraces and here he found a new world—a world of sunlight and luxuriant foliage, peopled by strange birds of gorgeous plumage which darted swiftly hither and thither. There were flying reptiles, too, and great gaudy moths. Snakes coiled upon many a branch and because they were of varieties unknown to him, he did not know whether they constituted a real menace or not. It was at once a beautiful and a repulsive world, but the feature of it which attracted him most was its silence, for its denizens seemed to be voiceless. The presence of the snakes and the dense foliage rendered it an unsatisfactory world for one who wished to travel swiftly and so the ape-man dropped to a lower level, and here he found the forest more open and the scent spoor clearer in his nostrils.
Not once had he doubted the origin of that scent, although it seemed preposterously unbelievable that he should discover it here in this gloomy wood in vast Pellucidar.
He was moving very rapidly for he wished, if possible, to reach his destination ahead of the Horibs. He hoped that his escape might delay the lizard-men and this was, in fact, the case, for they had halted immediately while a number of them had climbed into the trees searching for Tarzan. There was little in their almost expressionless faces to denote their anger, but the sickly bluish cast which overspread their scales denoted their mounting rage at the ease with which this gilak prisoner had escaped them, and when, finally, thwarted in their search, they resumed their interrupted march, they were in a particularly ugly mood.
Far ahead of them now Tarzan of the Apes dropped to the lower terraces. Strong in his nostrils was the scent spoor he had been following, telling him in a language more dependable than words that he had but little further to go to find those he sought, and a moment later he dropped down into one of the gloomy aisles of the forest, dropping as from heaven into the astonished view of ten stalwart warriors.
For an instant they stood looking at him in wide-eyed amazement and then they ran forward and threw themselves upon their knees about him, kissing his hands as they shed tears of happiness. "Oh, Bwana, Bwana," they cried; "it is indeed you! Mulungu has been good to his children; he has given their Big Bwana back to them alive."
"And now I have work for you, my children," said Tarzan; "the snake people are coming and with them is a girl whom they have captured. I thank God that you are armed with rifles and I hope that you have plenty of ammunition."
"We have saved it, Bwana, using our spears and our arrows whenever we could."
"Good," said Tarzan; "we shall need it now. How far are we from the ship?"
"I do not know," said Muviro.
"You do not know?" repeated Tarzan.
"No, Bwana, we are lost. We have been lost for a long while," replied the chief of the Waziri.
"What were you doing away from the ship alone?" demanded Tarzan.
"We were sent out with Gridley and Von Horst to search for you, Bwana."
"Where are they?" asked Tarzan.
"A long time ago, I do not know how long, we became separated from Gridley and never saw him again. At that time it was savage beasts that separated us, but how Von Horst became separated from us we do not know. We had found a cave and had gone into it to sleep; when we awoke Von Horst was gone; we never saw him again."
"They are coming!" warned Tarzan.
"I hear them, Bwana," replied Muviro.
"Have you seen them—the snake people?" asked Tarzan.
"No, Bwana, we have seen no people for a long time; only beasts—terrible beasts."
"You are going to see some terrible men now," Tarzan warned them; "but do not be frightened by their appearance. Your bullets will bring them down."
"When, Bwana, have you seen a Waziri frightened?" asked Muviro proudly.
The ape-man smiled. "One of you let me take his rifle," he said, "and then spread out through the forest. I do not know exactly where they will pass, but the moment that any of you makes contact with them commence shooting and shoot to kill, remembering, however, that the girl rides in front of one of them. Be careful that you do not harm her."
He had scarcely ceased speaking when the first of the Horibs rode into view. Tarzan and the Waziri made no effort to seek concealment and at the sight of them the leading Horib gave voice to a shrill cry of pleasure. Then a rifle spoke and the leading Horib writhed convulsively and toppled sideways to the ground. The others in the lead, depending upon the swiftness of their mounts, darted quickly toward the Waziri and the tall, white giant who led them, but swifter than the Gorobors were the bullets of the outer world. As fast as Tarzan and the Waziri could fire the Horibs fell. Never before had they known defeat. They blazed blue with rage, which faded to a muddy gray when the bullets found their hearts and they rolled dead upon the ground.
So swiftly did the Gorobors move and so rapidly did Tarzan and the Waziri fire that the engagement was decided within a few minutes of its inception, and now the remaining Horibs, discovering that they could not hope to overcome and capture gilaks armed with these strange weapons that hit them more swiftly than they could hurl their lances, turned and scattered in an effort to pass around the enemy and continue on their way.
As yet Tarzan had not caught a glimpse of Jana, though he knew that she must be there somewhere in the rear of the remaining Horibs, and then he saw her as she flashed by in the distance, borne swiftly upon the back of a fleet Gorobor. What appeared to be the only chance to save her now was to shoot down the swift beast upon which she was being borne away. Tarzan swung his rifle to his shoulder and at the same instant a riderless Gorobor struck him in the back and sent him sprawling upon the ground. By the time he had regained his feet, Jana and her captor were out of sight, hidden by the boles of intervening trees.
Milling near the Waziri were a number of terrified, riderless Gorobors. It was from this number that the fellow had broken who had knocked Tarzan down. The beasts seemed to be lost without the guidance of their masters, but when they saw one of their number start in pursuit of the Horibs who had ridden away, the others followed and in their mad rush these savage beasts constituted as great a menace as the Horibs themselves.
Muviro and his warriors leaped nimbly behind the boles of large trees to escape them, but to the mind of the ape-man they carried a new hope, offering as they did the only means whereby he might overtake the Horib who was bearing away The Red Flower of Zoram, and then, to the horror and astonishment of the Waziri, Tarzan leaped to the back of one of the great lizards as it scuttled abreast of him. Locking his toes beneath its elbows, as he had seen the Horibs do, he was carried swiftly in the mad rush of the creature to overtake its fellows and its masters. No need to urge it on, if he had known what means to employ to do so, for probably still terrified and excited by the battle it darted with incredible swiftness among the boles of the gray trees, outstripping its fellows and leaving them behind.
Presently, just ahead of him, Tarzan saw the Horib who was bearing Jana away and he saw, too, that he would soon overtake him, but so swiftly was his own mount running that it seemed quite likely that he would be carried past Jana without being able to accomplish anything toward her rescue, and with this thought came the realization that he must stop the Horib's mount.
There was just an instant in which to decide and act, but in that instant he raised his rifle and fired. Perhaps it was a wonderful bit of marksmanship, or perhaps it was just luck, but the bullet struck the Gorobor in the spine and a moment later its hind legs collapsed and it rolled over on its side, pitching Jana and the Horib heavily to the ground. Simultaneously Tarzan's mount swept by and the ape-man, risking a bad fall, slipped from its back to go tumbling head over heels against the carcass of the Horib's mount.
