wouldn't give much for his chances, even in the best hospital. The best thing you can do now is to go to hell, and take your beetles with you," he added.

Bram, without replying, raised his head and emitted from his throat the shrillest whistle that Tommy had ever heard. The response was amazing.

Rasping out of the darkness came eight beetles in pairs. Instead of leaping from an upright position, they trotted in the manner of horses, on all fours, their shells, which touched at the edges, forming a solid surface, gently rounded in the center so that a man's body could lie there and fit snugly into the groove.

"Help me get him up," said Bram. "Trust me! I'll do my best for him. If we leave him here they may kill and eat him. I can't trust all those beetle guards."

Tommy hesitated a moment, then decided to follow Bram's suggestion. Together they raised the unconscious man to the beetle-shell couch. Bram seated himself upon the boss of one of the beetle-shells in front, and Tommy jumped up behind.

Next moment, to his amazement, the trained steeds were flying smoothly through the air, at a rate that could not have been less than seventy-five to eighty miles an hour.

Tommy's shell seat was not a bed of roses, but he hardly noticed that. He was thinking that if Dodd lived they should be able to turn the tables.

For, unknown to Bram, he was in possession of the cigarette-lighter which he had picked up, and which Bram, in his agitation, had forgotten. It was full of petrol, or some other fluid of a similar nature, which Bram must have obtained from some natural source within the earth. And, in an emergency, Tommy knew that he had the means of keeping the beetles at bay.

They had traveled for perhaps an hour when a faint light began to glow in the distance. It grew brighter, and a roaring sound became audible. A turn of the track that they were traversing, and the light became a glare. A terrific sight met Tommy's eyes.

Out of the bowels of the earth—actually out of the crust beneath their feet—there shot a pillar of roaring flame, of intense white color, and radiating a heat that was perceptible even at a distance of several hundred yards. The beetle steeds dropped gently to the ground; they halted. Bram got down, grinning.

"Nicely trained horses, what?" he asked. "By the way, you have the advantage of me in names. Who and what are you?"

Tommy told him.

"Well, Travers, it looks as if we're going to be companions for some time to come, and I quite admit you saved my life back there. So we don't want to start with secrets. This is a natural petrol spring, which has probably been burning undiminished for ages. My trained beetles are blind—you didn't happen to notice I'd cut off their antenna? But the rest of the swarm daren't come near it. So that makes me their master.

"Pretty trick, what, Travers? I'm the Lord of the Flame down here, and I'm using my advantage. But don't get the idea of supplanting me. There are lots of other tricks you don't know anything about, and I'll have to trust you better before—"

He broke off and slipped another pellet into his mouth.

"Help me get Dodd down, if this is our destination," answered Tommy.

They lifted Dodd to the ground. He was conscious now, and moaning for water. The two men carried him into a sort of large cavern, at the farther end of which the fire was roaring. Bram went to a spring that trickled down one side, filled something that looked like a petrified lily calyx, and brought it to Dodd, who drained it.

Tommy looked about him. He was astonished to see that the place was, in a way, furnished. Bram had carved out a very creditable couch, and several low chairs, evidently with a stone ax, for by the light of the fire, which cast a fair illumination even at that distance, Tommy could see the marks of the implement, rough and irregular, in the wood.

On the ground were thick rugs, woven of hair, and two or three more rugs of the same material lay on the couch. It was evident that the human herd was expected to furnish textile materials as well as meat.

"Sit down, and make yourself comfortable," said Bram, when they had raised Dodd to the couch. "We'll have dinner, and then we'll talk. I can give you a fine vegetarian meal. Those dirty shrimp-eating savages look on me as a cannibal because I eat the fruits of the trees." He grinned. "There's a bad shortage of food in Submundia, as I've named this part of the world," he went on, "for until I came the beetles simply devoured the humans wholesale, instead of breeding them, like I taught them. And there's another of the hundred-and-fifty year swarms due to hatch out soon. However, we'll talk about that later. And all those fine fruits going to waste! Excuse me, Travers."

He disappeared, and returned in a minute or two with a small table, piled high with luscious fruits unknown to Tommy, though among them were some that looked like loaves of natural bread.

Tommy, whose appetite never failed him even in the worst circumstances, fell to with a will. He was enjoying his meal when he happened to look up, and saw that the penumbra at the edge of the lighted zone was dense with beetles.

Thousands—perhaps millions, for they stretched away as far as the eye could see, were packed together, their antenna waving in unison, their heads, beneath the shells, directed toward the fire.

Bram saw Tommy's look of disgust, and laughed. "The fire seems to intoxicate them, Travers," he said. "They always throng the entrance when I'm here. It's as far as they dare go. They're quite blind in the least light. Care to smoke? I've learned the art of making some quite decent cigars." He produced a handful. "Oh, by the way, you didn't see my lighter anywhere, did you?" he went on, with a pretense of carelessness.

"No," lied Tommy. "I was surprised you—"

"Oh, there's a supply of petrol in the rocks. No matter," answered Bram carelessly. "Your friend looks bad," he added, glancing at Dodd, who had fallen asleep. "Travers, I'm sorry I lost my temper. The—the shock of meeting men from the upper world, you know."

Dodd opened his eyes and tried to whisper. Tommy bent over him and listened.

"He wants to know whether he can have that girl to take care of him," he said.

"What, the one I saw you with? Why, she's a cull, Travers."

"What d'you mean?" asked Tommy.

"Why—useless, you know. There's several of them running loose, and waiting to be rounded up. We raise two breeds, one for replenishing the stock, and one for meat. She's just a cull, a reversion, no use for either purpose. I'll have her brought by all means. I—I like Dodd. I want to get him to like me," Bram went on, with a sort of penitence that had a pathetic touch. "Our little differences—quite absurd, and I can prove he's wrong in his ideas.

"Make yourself comfortable as long as you're here, Travers, and don't mind me. Only, don't try to escape. The beetles will get you if you do, and there's no way out of here—none that you'll find. And don't try to follow me. But you're a sensible man, and we'll all get along famously, I'm sure, as soon as Dodd recovers."
