"It was large," said Tommy ruefully. "I didn't even get a good look it the thing. Probably just as well, though. I might have been--er--delayed. Good Lord! What's that?" A light had sprung into being somewhere. It was bright. It was blinding in its brilliance. Coming through the tangled jungle growth, it seemed as if spears of flame shot through the air, irradiating stray patches of scabrous tree-trunk with unbearable light. For an instant the illumination held. Then there was a distant, cracking detonation. The unmistakable explosion of gun-cotton split the air, and its echoes rolled and reverberated through the jungle. The light went out. Then came a thin, high yelling sound which, faint as it was, had something of the quality of hysterical glee. That crazy ululation kept up for several minutes. Evelyn shivered. "The Ragged Men," said Tommy very quietly. "They sneaked up on the Tube. They flung blazing thermit, or something like it, with a weapon captured from the Golden City. That explosion was the grenades going off. I'm afraid the Tube's blown up, Evelyn." She caught her breath, looking mutely up at him. "Here's a pistol," he said briefly, "and shells. There's no use our going to the Tube to-night. It would be dangerous. We'll do our investigating at dawn." * * * * * He found a crevice where tree-fern trunks grew close together and closed in three sides of a sort of roofless cave. He seated himself grimly at the opening to wait for daybreak. He was not easy in his mind. There had been two Tubes to the Fifth-Dimension world. One had been made by Jacaro for his gunmen. That was now held by the men of the Golden City, as was proved by carnivorous lizards and the Death Mist that had come down it. The other was now blown up or, worse, in the hands of the Ragged Men. In any case Tommy and Evelyn were isolated upon a strange planet in a strange universe. To fall into the hands of the Ragged Men was to die horribly, and the Golden City would not now welcome inhabitants of the world Jacaro and his men had come from. To the civilized men of this world, Jacaro's raids would seem invasion. They would seem acts of war on the part of the people of Earth. And the people of Earth, all of them, would seem enemies. Jacaro would never be identified as an unauthorized invader. He would seem to be a scout, an advance guard, a spy, for hordes of other invaders yet to come. As the long night wore away, Tommy's grim hopelessness intensified. The Ragged Men would hunt them for sport and out of hatred for all sane human beings. The men of the Golden City would be merciless to compatriots of Jacaro's gunmen. And Tommy had Evelyn to look out for. * * * * * When dawn came, his face was drawn and lined. Evelyn woke with a little gasp, staring affrightedly about her. Then she tried gamely to smile.
