For many minutes Thad stood upon the deck, waiting, tensely grasping the welding tool. But the nerve-shattering scream did not come again. Nor any other sound. The yellow dog seemed half to forget its fear. It leaped up at his face again, with another short little bark.
The air must be good, he thought, if the dog could live in it.
He unscrewed the face-plate of his helmet, and lifted it. The air that struck his face was cool and clean. He breathed deeply, gratefully. And at first he did not notice the strange odor upon it: a curious, unpleasant scent, earthly, almost fetid, unfamiliar.
The dog kept leaping up, whining.
"Hungry, boy?" Thad whispered.
He fumbled in the bulky inside pockets of his suit, found a slab of concentrated food, and tossed it out through the opened panel. The dog sprang upon it, wolfed it eagerly, and came back to his side.
Thad set at once about exploring the ship.
First he ascended the ladder to the bridge. A metal dome covered it, studded with transparent ports. Charts and instruments were in order. And the room was vacant, heavy with the fatal silence of the ship.
Thad had no expert's knowledge of the flier's mechanism. But he had studied interplanetary navigation, to qualify for his license to carry masses of metal under rocket power through the space lanes and into planetary atmospheres. He was sure he could manage the ship if its mechanism were in good order, though he was uncertain of his ability to make any considerable repairs.
