And then something happened that he had not in the least expected. One moment he seemed to be traveling in a complete calm, a sort of clear funnel with a ring of swirling fog outside it--the next he was dropping into a void! There was no air resistance--there seemed hardly any air, for he felt a choking in his throat, and a tearing at his lungs as he strove to breathe. He heard a strangled cry from Dodd, and saw that he was clutching with both hands at his throat, and his face was turning purple. The controls went limp in Tommy's hands. The plane, gyrating more slowly, suddenly nosed down, hung for a moment in that void, and then plunged toward the green earth, two hundred feet below, with appalling swiftness. Tommy realized that a crash was inevitable. He threw his goggles up over his forehead, turned and waved to Dodd in ironic farewell. He saw the earth rush up at him--then came the shattering crash, and then oblivion! CHAPTER II _Beetles and Humans_ How long he had remained unconscious, Tommy had no means of determining. Of a sudden he found himself lying on the ground beside the shattered plane, with his eyes wide open. He stared at it, and stared about him, without understanding where he was, or what had happened to him. His first idea was that he had crashed on the golf links near Mitchell Field, Long Island, for all about him were stretches of verdant grass and small shrubby plants. Then, when he remembered the expedition, he was convinced that he had been dreaming. What brought him to a saner view was the discovery that he was enveloped in furs which were insufferably hot. He half raised himself and succeeded in unfastening his fur coat, and thus discovered that apparently none of his bones was broken. But the plane must have fallen from a considerable height to have been smashed so badly. Then Tommy discovered that he was lying upon an extensive mound of sand, thrown up as by some gigantic mole, for burrow tracks ran through it in every direction. It was this that had saved his life. Something was moving at his side. It was half-submerged in the sand-pile, and it was moving parallel to him with great rapidity. A grayish body, half-covered with grains of sand emerged, waving two enormously long tentacles. It was a shrimp, but fully three feet in length, and Tommy had never before had any idea what an unpleasant object a shrimp is. Tommy staggered to his feet and dropped nearer the plane, eyeing the shrimp with horror. But he was soon relieved as he discovered that it was apparently harmless. It slithered away and once more buried itself in the pile of sand. Now Tommy was beginning to remember. He looked into the wreckage of the plane. Jim Dodd was not there. He called his name repeatedly, and there was no response, except a dull echo from the ice-mountains behind the veil of fog. * * * * *
