distress at finding his master absent.
"It's all right. Cain," said Jim. "I'm here."
Side by side they flew steadily toward the base of the great cone, which was pouring out a fan-shaped stream of fire. Rumblings shook the earth; it was evident that another upheaval was in course of preparation. The long column of the Drilgoes could be seen, extending around the flank of the mountain.
Then of a sudden the Eye opened. And across the causeway came the blue-white Ray, carrying death and destruction.
The Drilgoes, who had learned wisdom, remained concealed out of the Ray's path, and escaped, but a great dinosaur, fifty or sixty feet in length, startled by the light, came blundering out of the ferns, uttered a bellow, and melted into an amorphous mass. Birds dropped from their roosting places with a sound like that of falling hail. Black paths were cloven through the midst of the jungle.
Rifle in hand, Jim soared into the air, and shot forward, high above the causeway toward the glowing Eye.
He had noticed that the blue-white ray appeared in cycles of about two minutes, and had made his plans accordingly. Two minutes in which to accomplish his task, or take the chance of a hideous death. Some thirty seconds carried him right into the glowing heart of the winking Eye; he hovered and raised his rifle.
Underneath him the breakers thundered; round the Eye a myriad seabirds fluttered, dashing themselves against it, falling into the waves. Huge and high the great city towered into the skies, lit by its soft incandescence. Jim could see the throngs in the streets, the traffic. But what was happening on the other side of the Eye?
SUDDENLY he saw the moon in her third quarter sailing through the skies, and a hideous fear overcame him. Suppose Tode had met with treachery; suppose that this very night Lucille were doomed to be sacrificed to the terrible god Cruk!
Suppose that even at that moment her tender flesh were being sacrificed by the awful hooks!
He drew a bead upon the Eye and fired—and missed. The bullet went wide. But even if it struck, what guarantee had he that it would shatter the glass, or whatever substance it was that covered the orb?
He lost position, and knew that the two-minute interval was drawing to a close. He soared and fired again. The Eye still glowed.
Then of a sudden a blinding ray shot forth from it, so dazzling that it seemed to sear Jim's eyeballs. The interval was ended.
It shot beneath him, but no more than a few feet, and, turning his eyes shoreward, Jim saw it sweep along the causeway and tear a black path through the forest. Frantically he soared, and circled around the temple.
The ray went out. Two minutes more. And now the temporary panic had passed; Jim's nerves grew steady as a rock. He eased the controls and floated in toward the glowing orb. Seamews, screaming, dashed themselves against it and fell, wounded and broken, into the breaking seas below. They fluttered past Jim's face, one impacted against his chest with a thud that rocked him where he hovered.
But Jim knew that he could not fail. At a distance of fifty feet he drew a bead upon the centre of the Eye and pressed the trigger.
And instantly the light went out....
CHAPTER X
The Fight in the Dark
HE dropped down softly to the causeway. Within the city he heard a sound such as he had never heard before, as if some ancient prophecy of doom had been fulfilled, a wailing "Aiah! Aiah! Aiah!" that was caught up from throat to throat and
