He raised his heat-gun, fired once, saw the feathers burst into blue flame, saw it falling; then he rolled over and went back to sleep. Not even the thud of its heavy body on the sand disturbed him, but an hour later he heard another warning⁠—a rasping sound⁠—and through the stench of the ancient swamp he smelled a fetidness that meant danger.

This time as he turned he rolled to his feet. He saw the huge coils of the Venusian water-constrictor. One lidless phosphorescent eye gleamed evilly at him, but its great jaws were spread and the dead fish was halfway down its bone-plated throat.

Grant Russell relaxed. Ordinarily he would have been scared to death to be within miles of the big saurian. But now for a few hours, with the fish in its throat it would be comparatively harmless.

Grant rubbed his eyes and stretched. How wonderful sleep could be! For six weeks he had been in the swamp where he never had dared to take off his diving-suit even when he was resting on a clump of floating grass, for fear it would suddenly sink and drop him into a hundred feet of brown water; six weeks walking through mud sometimes over his head, with the brown, infested water above that; six weeks pitting all his swamp lore against sudden death in a thousand forms, with only the light gravity of Venus to aid him, and his indomitable determination to keep him going. But now he felt like a million.

No man had ever crossed the Great Swamp alone on foot before. Few had crossed it in any fashion. Few would have tried it but Grant Russell because few wanted to do it as much as he did. In spite of his small size and his scrawny muscles, in spite of Venus which catered to big men and strong men, he had done it.

The food problem alone would have stopped most men, but Grant had spent a lot of time around the swamps of Venus. Often he had gone prospecting with food enough for only one week because he couldn’t buy more, and he had stayed four, five, six weeks.
