"I'm all right," he said, with a rather sickly smile; "but," drawing his hand across his brow and cheek, "he got me here, and I thought it was a hot iron. Where is he now?"

"Dead," said Edmund.

"Jo, I'd have liked to finish him myself!"

We were worried by the appearance of the wound, like a long, deep scratch, on Jack's face, but, of course, we said nothing about our worriment to him. Edmund bound it up, as best he could, and it afterwards healed, but it took a long time about it, and left a mark that never disappeared. There was probably a little poison in it.

Edmund himself needed the attention of a surgeon, for his wrists had been cruelly burned by the matches, but he would not allow us to speak of his sufferings, and putting on some slight bandages, he declared that it was time now to get out of this wilderness of horrors. He communicated with Ala, and in a few minutes we were speeding, at a high elevation, toward the land of the opaline dome. So far above the morasses we no longer heard the brute voices of its terrible inhabitants, nor saw the swaying of the branches as they looked about in search of prey.

"This," said Edmund, "exceeds everything that I could have imagined. I do not know in what classification to put any of the strange beasts that we have seen. They can only be likened to the monsters of the early dawn on the earth, in the age of the dinosaurs. But they are sui generis, and would make our anatomists and paleontologists stare. I am only surprised that we have encountered no flying dragons here."

"But was it really a—a giant spider that captured Ala's man?" I asked with a shudder.

"God knows what it was! It had the form of a spider, and it leaped like one. If it had been armored I could never have killed it. I think the shock of its impact against the air ship helped to finish it."

It was only after we had issued from under the curtain of twilight that we learned the story of the chase which had brought our salvation. Edmund first obtained it from Ala and Juba, filling out the outlines of their wordless narrative with his ready power of interpretation, and then he told it to us."

"We owe our lives to Juba," he said. "Ala had just returned to the mine from the capital when our abduction took place. Juba, who had wandered out on our track, saw from a distance the seizure, and a few minutes afterwards Ala's air ship arrived. He instantly communicated the facts to her, and without losing an instant the chase was begun. Ingra's delay in choosing his course was the thing that saved us. They knew that they must not lose sight of us for an instant, and their motors were driven to their highest capacity. Fortunately, Ala's vessel is one of the speediest, and they were able to gain on us from the start. Slowly they drew up until the border of the twilight zone was reached. Then as we entered under the clouds we were swallowed from the sight of all except Juba. But for his wonderful eyes, there would have been no hope of continuing the chase. He had lived all his life in a land of darkness and now he began to feel himself at home. Throwing off the shades which he has worn since our arrival, he had no difficulty in following the movements of Ingra, even after our vessel had completely faded from the view of all the others. So, without abating their fearful speed, they plunged into the gloom straight upon our track. The nose of the bloodhound is not more certain in the chase than were Juba's eyes in that terrible flight through the darkness. When Ingra changed his course and doubled, Juba saw the maneuver and turned the dodge against its inventor, for now Ingra could not see them, and did not know that they were still on his track. They cut off the corners, and gained so rapidly that they were close at hand when Ingra rose from the swamp after pitching us overboard. They had heard Henry's cry, which served to tell them what had happened, and to direct them to the spot. But even Juba could not discern us in the midst of the vegetation, and it was the sudden flashing out of our lamp which revealed our location when they were about to pass directly over us."
