It was a round disc of bluish white, a disc like the moon, but slightly smaller, a disc that flickered as if it had an eyelid that was being winked repeatedly. Simultaneously screams broke from the throats of all the Drilgoes. They stampeded.

Tode whirled about and saw. With a curse he leaped into the air and whirred away.

Out of that disc a slender, blue-white beam shot suddenly, driving a pathway through the fog, and disclosing the dark depths of the valley.

"The Eye! The Eye!" screeched Parrish. "Down on the ground! Down!

Down!"

He dropped, and Jim caught Lucille and flung himself headlong with her. To and fro overhead, but only a few feet above them, moved the searchlight. Shrieks broke from the Drilgoes' throats as they scattered through the jungle.

Everywhere that ray moved, trees and undergrowth simply disappeared. A bunch of Drilgoes, caught by it, were obliterated in an instant. Great gaps were left through the undergrowth as the ray pa.s.sed.

It faded as quickly as it had come, and instantly old Parrish was on his feet, dragging at his daughter.

"Now! Now!" he babbled, heading along one of the burned tracks through the undergrowth.

Jim seized Lucille and the two raced in the wake of old Parrish.

Behind them they could hear the Drilgoes shouting, but a dense, impenetrable darkness was already beginning to settle down over the valley. They lost the track and went crashing through the ferns, on and on until all was silence about them.

Suddenly Parrish went down like a log. He lay breathing heavily, completely exhausted. When Jim spoke to him a feeble muttering was the only answer. Jim and Lucille dropped to the ground exhausted beside him.

CHAPTER V

_The Eye of Atlantis_

For perhaps half an hour the three lay there, hearing nothing. It seemed to be night, for the darkness was impenetrable, save for the lurid flashes of fire from the volcano. Parrish, who was slowly recovering his strength, was mumbling incessantly. It was with difficulty that Jim recalled him to a realization of his surroundings.

"Where is the city of Atlantis?" he asked him.

"Over there," mumbled Parrish. "Behind the volcano. Why do you ask me?"

"I'm thinking of going there."

"Eh? Going there? You're mad. The Eye will see you, the Eye that can see for a hundred miles. They'll turn the Ray on you. Nothing is too small for the Eye. And they watch night and day."

"The Eye is off now."

"It's never off. The Eye is dark. It grows white only when they are about to use the Ray. Perhaps the Eye is watching us now."

"Nevertheless," said Jim, "I think we would do well to try to enter the city. We can't live here in the jungle at the mercy of these Drilgoes."

"It is impossible to enter. All strangers are killed by the Atlanteans."

"Dad," interposed Lucille, "I think we'd better do what Jim suggests.

One of us must decide."

"My idea is that you take us to some place where we can get a view of the city," said Jim. "Then we can make up our minds what to do. We've got to get somewhere out of this jungle."

Parrish rose to his feet, mumbling. "If we go round the base of the volcano we can see Atlantis," he said. "It's always light there. In the daytime they drive away the fogs by some means they've got, and at night they have an artificial sun. But we'll be killed, we'll all be killed."

Mumbling and muttering, he began groping his way through the undergrowth in the direction of the volcano, whose flashes were again becoming more frequent, affording a means of directing their route.

Obscure rumblings were again beginning to shake the earth. For an hour the three picked their way steadily upward through the ferns, until the ground became more open.

They were approaching the base of the volcano, whose side now towered above them, the upper part gla.s.sy with vitreous lava.

Suddenly Parrish, who was still leading, stopped and began to tremble with fear. Stepping to his side, Jim heard the low muttering of voices not far away.

Very cautiously he moved forward through the thin fern scrub, until the glow of burning embers caught his sight. He stopped, hearing the voices more distinctly, and again moved forward.

Three Drilgoes, huge, b.e.s.t.i.a.l men, and evidently an outpost, were squatting around the ashes, devouring something with noisy gusto.

Softly as Jim had moved, their acute ears had caught the sound of his footsteps. They rose, still holding what they were eating in their hands, and, grasping their stone spears, moved in three separate ways toward the edge of the clearing.

The man nearest Jim uttered a guttural exclamation and, after sniffing a moment, began to lope in his direction. Suddenly he stopped short, petrified with astonishment and fear at the sight of a man who, instinct told him, was neither Atlantean nor of his own kind.

Jim leaped, tackling him about the knees, and brought him heavily to the ground. As the Drilgo fell, the spear clattered from his hand, but from his snakeskin girdle he pulled a long, curved knife of chipped obsidian, sharp as a razor.

Jim grasped the Drilgo's wrist, but in a moment he saw that he was no match for the creature in strength. He drew back his right arm and delivered a punch to the solar plexus with all his strength.

As the Drilgo's hand grew limp he s.n.a.t.c.hed away the knife. There was no helping what he did for the two others were close upon him.

A thrust, a slashing blow, and the Drilgo was weltering in his life-blood. A backward leap, and Jim evaded the flung spear by a hair's breadth.

Knife in hand he leaped forward, and, dodging in beneath the long shaft of the weapon, got in a slash that almost cut the Drilgo's body in two.

The third Drilgo, seeing his two companions in their death-throes, flung away his spear and fled with loud howls into the jungle.

Jim stepped back. Lucille and her father were already almost at his heels. "It's all right," he called. "Come this way!" He led them through the ferny growth in such a manner that they should not see the two dead bodies. Nevertheless, he felt that Lucille knew.

"Let's see what they were cooking," he said.

But again he turned quickly. He could not know for sure what flesh that was, roasting and scorching on the embers, and he had no desire to know. It might have been monkey, but ... he turned away, and as he did so, Parrish picked up several round objects that were lying a little distance away.

"These are good to eat," he said. "A sort of bread-fruit. I've lived on it for five years," he added with a sort of grotesque pathos.

They munched the fruit as they proceeded up the mountain, and found it satisfying. Parrish seemed more himself again, though he still muttered at intervals. Lucille clung closely to Jim as they proceeded.

They were treading on lava now, vitreous, and smooth as gla.s.s. It was impossible to proceed further in that direction. They turned their steps around the base in the direction of the sea.

After another hour, during which their way was lit by almost continuous lurid flashes from the crater, a patch of illumination, apparently out at sea, began to become visible. A half hour more, and they were rounding the volcano's base, and suddenly it burst upon them, a stupendous spectacle that drew an exclamation of amazement from Jim's lips.
