hand, this time upon the pulpy flesh of the downward-opening mouth.
An inch higher, and he would have impaled his hand upon the beak, with a point like a needle, and evidently used for purposes of attack, since it was not connected with the mandibles. The blow appeared to fall in the only vulnerable place. The monster dropped upon its back and lay there, unable to reverse itself, its antenna and forelegs waving in the air, and the rear legs rasping together in a shrill, strident shriek.
Instantly, as Tommy darted out of the way, the swarm fell upon the helpless monster and began devouring it, tearing strips of flesh from the lower shell, which in the space of a half-minute was reduced simply to bone. The most horrible feature of this act of cannibalism was the complete silence with which it was performed, except for the rasping of the dying monster's legs. It was evident that the huge beetles had no vocal apparatus.
For the moment left unguarded, Jim Dodd flung down the collar of his fur coat, stared about him, and recognized Tommy.
"My God, it's you!" he yelled. "Well, can you—?"
He had no time to finish his sentence. A pair of antenna went round his neck from behind. At the same instant Tommy, the old man, and the girl were gripped by the monsters, which, forming a solid phalanx about them, began hustling them in the direction of the hole. Resistance was utterly impossible. Tommy felt as if he was being pushed along by a moving wall of stone.
Inside the opening it was completely dark. Tommy shouted to Dodd, but the strident sounds of the moving legs drowned his cries. He was being pushed forward into the unknown.
SUDDENLY the ground seemed to fall away beneath his feet. He struggled, cried out, and felt himself descending through the air.
For a full half-minute he went downward at a speed that constricted his throat so that he could hardly draw breath. Then, just as he had nerved himself for the imminent crash, the speed of his descent was checked. In another moment he found that he was slowing to a standstill in mid-air.
He was beginning to float backward—upward. But the wall of moving shells, pushing against him, forced him on, downward, and yet apparently against the force of gravitation.
Then of a sudden Tommy was aware of a dim light all about him. His feet touched earth and grass as softly as a thistledown alighting.
He found himself seated in the same dim light upon red grass, and staring into Jimmy's face.
CHAPTER III
Ten Miles Underground
"WHAT I was going to say when we were interrupted, was, 'Can you beat it?'" Jimmy Dodd observed, with admirable sang-froid.
They were still seated on the red grass, gazing about them at what looked like an illimitable plain, and upward into depths of darkness. It was warm, and the light, furnished by what appeared to be luminous vegetation, was about that of twilight.
On every side were clumps of trees and shrubs, which formed centers of phosphorescent illumination, but for the most part the land was open, and here and there human figures appeared, moving with head down and arms hanging earthward.
"No, I'm damned if I can," said Tommy. "What happened to you after we crashed?"
"Why, first thing I knew, I found myself riding on the back of a fossil beetle, apparently one of the curculionidae," said Dodd.
"Never, mind being so precise, Jimmy. Let's call it a beetle. Go on."
"They set me down inside the hole and seemed to be investigating me, the
