"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 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, out-stripping 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.
