Hands on each other's shoulders, they stood there in the gathering dark, where grotesque trees arched twistingly overhead. Their moment of depression had passed; Earth had called, and they had heard it, each after his own fashion. But to each the call had been one of clear courage. No longer cast off and forlorn, they were one with their own world. "Down," said Professor Sykes with a whimsical smile; "down, but not out!" And the lieutenant responded in kind. "Are we down-hearted?" he demanded loudly. And the two turned as one man to grin at the scarlet one as they thundered. "N-o-o!" CHAPTER X Two men grinned in derision at the horrible, man-shaped thing that held their destinies in his lean, inhuman hands!--but they turned abruptly away to look again above them where that bright star still shone through an opening in the clouds. "The earth! Home!" It seemed as if they could never tear their eyes away from the sight. Their captor whistled an order, and the guard of four tugged vainly at the two, who resisted that they might gaze upon their own world until the closing clouds should blot it from sight. A cry from one of the red guards roused them. The dark was closing in fast, and their surroundings were dim. Vaguely, McGuire felt more than saw one of the red figures whirled into the air. He sensed a movement in the jungle darkness where were groves of weird trees and the tangle of huge vegetable growths. What it was he could not say, but he felt the guard who clutched at him quiver in terror. Their leader snatched at the instrument that hung about his neck and put it to his lips; he whistled an order, sharp and shrill. Blazing light that seemed to flame in the air was the response; the air was aglow with an all-pervading brilliance like that in the car that had whirled them from the landing field. The light was everywhere, and the building before them was surrounded by a dazzling envelope of luminosity. Whatever of motion or menace there had been ceased abruptly. Their guard, three now in number instead of four, seized them roughly and hustled them toward an open door. No time, as they passed, for more than fleeting impressions: a hall of warm, glowing light--a passage that branched off--and, at the end, a room into which they were thrown, while a metal door clanged behind them. * * * * * These were no gentle hands that hurled the men staggering through the doorway, and Professor Sykes fell headlong upon the glassy floor. He sprang to his feet, his face aflame with anger. "The miserable beasts!" he shouted. "Take it easy," admonished the flyer. "We're in the hoose-gow; no use of getting all fussed up if they don't behave like perfect gentlemen. "There's a bunk in the corner," he said, and pointed to a woven hammock that was covered with soft cloths; "and here's another that I can sling. Twin beds! What more do you want?"
