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.
