"They are invincible," Bram went on. "Their fecundity is such that when the new swarm is hatched out their numbers alone will make them irresistible. They do not know fear. They shrink from nothing. And they will follow me, their leader-I, who know the means of controlling them. How, then, can puny man hope to stand against them?
"Join me, gentlemen," Bram went on. "And beware how you decide rashly. For this is the supreme moment, not only of your own lives, but for all humanity and beetledom. Upon your decision hangs the future of the world.
"For, irresistible as the beetles are, there is on thing they lack. That is the sense of historic continuity. If they destroy man, they will know nothing of man"s achievements, poor though these are. My own work on the fossil monotremes-"
"Which is a tissue of inaccuracies and half-baked deductions!" shouted Dodd.
Bram started as if a whip had lashed him. "Liar!" he bawled. "Do you think that I, who left the Greystoke expedition in a howling blizzard because I knew that here, in the inner earth, I could refute your miserable impostures-do you think that I am in the mood to listen to your wretched farrago of impossibilities?"
"Listen to me," bawled Dodd, advancing with waving arms. "Once and for all, let me tell you that your deductions are all based upon fallacious premises. No, I will not shut up, Tom Travers! You want me to aid your d.a.m.ned beetles in the destruction of humanity! I tell you that your phascalotherium, amphitherium, and all the rest of them, including the marsupial lion, are degenerate developments of the age following the pleistocene. I say the whole insect world was made to fertilize the plant world, so that it should bear fruit for human food. Man is the summit of the scale of evolution, and I will never join in any infamous scheme for his destruction."
Bram glared at Dodd like a madman. Three times he opened his mouth to speak, but only inarticulate sounds came from his throat. And when at last he did speak, he said something that neither Dodd nor Tommy had antic.i.p.ated.
"It looks as if you"re not so paralysed as you made out," he sneered. "You"ll change your mind within what used to be called a day, Dodd. You"ll crawl to my feet and beg for pardon. And you"ll recant your lying theories about the fossil monotremes, or you die-the pair of you-you die!"
CHAPTER VI
Escape!
"I heard what he said. You shall not die. We shall go away to your place, where there are no beetles to eat us, even if"-Haidia shuddered-"even if we have to cross the bridge of fire, beyond which, they tell me, lies freedom."
High over and a little to one side of the petrol flame Dodd and Tommy had seen the slender arch of rock leading into another cleft in the rocks. They had investigated it several times, but always the fierce heat had driven them back.
Both Dodd and Tommy had noticed, however, that at times the fire seemed to shrink in volume and intensity. Observation had shown them that these times were periodical, recurring about every twelve hours.
"I think I"ve got the clue, Tommy," said Dodd, as the three watched the fiery fountain and speculated on the possibility of escape. "That flow of petrol is controlled, like the tides on earth, by the pull of the moon. Just now it is at its height. I"ve noticed that it loses pretty nearly half its volume at its alternating phase. If I"m right, we"ll make the attempt in about twelve hours."
"Bram"s given us twenty-four," said Tommy. "But how about getting Haidia across?"
"I go where you go," said Haidia, sidling up to Dodd and looking down upon him lovingly. "I do not afraid of the fire. If it burn me up, I go to the good place."
"Where"s that, Haidia?" asked Dodd.
"When we die, we go to a place where it is always dark and there are no beetles, and the ground is full of shrimps. We leave our bodies behind, like the beetles, and fly about happy for ever."
"Not a bad sort of place," said Dodd, squeezing Haidia"s arm. "If you think you"re ready to try to cross the bridge, we"ll start as soon as the fire gets lower."
"I"ll be on the job," answered Haidia, unconsciously reproducing a phrase of Tommy"s.
The girl glided away, and disappeared through the thick of the beetle crowd cl.u.s.tered about the entrance to the cavern. Tommy and Dodd had already discovered that it was through her ability to reproduce a certain beetle sound meaning "not good to eat" that the girl could come and go. They had once tried it on their own account, and had narrowly escaped the lashing tentacles.
After that there was nothing to do but wait. Three or four hours must have pa.s.sed when Bram returned from his inner cave.
"Well, Dodd, have you experienced a change of heart?" he sneered. "If you knew what"s in store for you, maybe you"d come to the conclusion that you"ve been too c.o.c.ksure about the monotremes. We"re slaughtering in the morning."
"That so?" asked Dodd.
"That"s so," shouted Bram. "The beetles are beginning to emerge from the pupae, and they"ll need food if they"re to be kept quiet. We"re rounding up about threescore of the culls-your friend Haidia will be among them. We"ve got some caged ichneumon flies, pretty little things only a foot long, which will sting them in certain nerve centers, rendering them powerless to move. Then we shall bury them, standing up, in the vegetable mould, for the beetles to devour alive, as soon as they come out of the sh.e.l.ls. You"ll feel pretty, Dodd, standing there unable to move, with the new born beetles biting chunks out of you."
Tommy shuddered, despite his hopes of their escaping. Bram, for a scientist, had a grim and picturesque imagination.
"Dodd, there is no personal quarrel between us," Bram went on. Again that note of pathetic pleading came into his voice. "Give up your mad ideas. Admit that the banded ant-eater, at least, existed before the pleistocene epoch, and everything can be settled. When you see what my beetles are going to do to humanity, you"ll be proud to join us. Only make a beginning. You remember the point I made in my paper, about spalacotherium in the Upper Jura.s.sic rocks. It would convince anybody but a hardened fanatic."
"I read your paper, and I saw your so-called spalacotherium, reconstructed from what you called a jaw-bone," shouted Dodd. "That so-called jaw-bone was a lump of chalk, made porous by water, and the rest was in your imagination. Do your worst, Bram, I"ll never crucify truth to save my life. And I"ll laugh at your spalacotherium when your beetles are eating me."
Bram yelled and shrieked, he stamped up and down the cavern, shaking his fists at Dodd. At last, with a final torrent of objurgation, he disappeared.
"A pleasant customer," said Tommy. "We"ll have to make that bridge, Jim, no question about it, even if it means death in the petrol fire."
"Fire"s dying down fast," answered Dodd. "Haidia ought to be here soon."
"If Bram hasn"t got her."
"Bram got-that girl? If Bram harms a hair of her head I"ll kill him with worse tortures than he"s ever dreamed of," answered Dodd, leaping up, white with rage.
"You mean you-?" Tommy began.
"Love her? Yes, I love her," shouted Dodd. "She"s a girl in a million. Just the sort of helpmate I need to a.s.sist me in my work when we get back. I tell you, Tommy, I didn"t know what love meant before I saw Haidia. I laughed at it as a romantic notion. "Oh lyric love, half angel and half bird!"" he quoted, beginning to stride up and down the cavern, while Tommy watched him in amazement.
And at this moment a complete beetle entered the cave. Complete, because it had a plastron, or breast-sh.e.l.l, as well as a back-sh.e.l.l, or carapace.
A double breast-sh.e.l.l! A new species of beetle? An executioner beetle, sent by Bram to summon them to the torture? Tommy shuddered, but Dodd, lost in his love ecstasy, was ignorant of the creature"s advent.
""Oh lyric love-"" he shouted again, as he twirled on his heel, to run smack into the monster. The crack of Dodd"s head against the beetle-sh.e.l.l re-echoed through the cave.
The double plastron dropped, the carapace fell down: Haidia stood revealed. The lovers, folded in each other"s arms, pa.s.sed momentarily into a trance.
It was Tommy who separated them. "We"ll have to make a move," he said. "I think the fire"s as low as it ever gets. Why did you bring the sh.e.l.ls, Haidia?"
"To save us all from the beetles," answered the girl. "When they see us in the sh.e.l.ls, they will not know we are human. That is what makes it so hard to have to be eaten by those beetles, when they are such dumb-bells," she added, reproducing another of Tommy"s words.
"Come," she continued bravely, "let us see if we can pa.s.s the fire."
The roaring fountain made the air a veritable inferno. Overhead the rocks were red-hot. A cascade of sparks tumbled in a fiery shower from the rock roof. Dodd, holding Haidia in his arms, to protect her, staggered ahead, with Tommy in the rear. Only the beetle-sh.e.l.ls, which acted as non-conductors of the heat, made that fiery pa.s.sage possible.
There was one moment when it seemed to Tommy as if he must let go, and drop into that raging furnace underneath. He heard Dodd bawling hoa.r.s.ely in front of him, he nerved himself to a last effort, beating fiercely at his blazing hair-and then the heat was past, and he had dropped unconscious upon a bed of cool earth beside a rushing river.
He was vaguely aware of being carried in Dodd"s arms, but a long time seemed to have pa.s.sed before he grew conscious again. He opened his eyes in utter darkness. Dodd was whispering in his ear.
"Tommy, old man, how are you feeling now?" Dodd asked.
"All-right," Tommy muttered. "How"s Haidia?"
"Still unconscious, poor girl. We"ve got to get out of here. I heard Bram yelling in the distance. He"s discovered our flight. There may be another way out of the cave, and, if so, he"ll stop at nothing to get us. See if you can stand, but keep your head low. There"s a low roof of rock above us."
"There"s water," said Tommy, listening to the roar of a torrent that seemed to be rushing past them.
"It"s a stream, and I believe these sh.e.l.ls will float and bear our weight. We"ve got to try. We"ve got to put everything to the touch now, Tommy. I"m going to lay Haidia on one of the sh.e.l.ls, poor girl, and start her off. Then I"ll follow, and you can bring up the rear."
