He edged back into the narrow cleft which was the entrance to the ledge. As a representative of his species he was not impressive, and now with those shudders he could not master, shaking his thin body, he looked even smaller and more vulnerable. Shann drew his knees up close under his chin. The hood of his woodsman's jacket was pushed back in spite of the chill of the morning, and he wiped the back of his hand across his lips and chin in an oddly childish gesture. None of the men below who had been alive only minutes earlier had been close friends of his; Shann had never known anyone but acquaintances in his short, roving life. Most people had ignored him completely except to give orders, and one or two had been actively malicious--like Garth Thorvald. Shann grimaced at a certain recent memory, and then that grimace faded into wonder. If young Thorvald hadn't purposefully tried to get Shann into trouble by opening the wolverines' cage, Shann wouldn't be here now--alive and safe for a time--he'd have been down there with the others. The wolverines! For the first time since Shann had heard the crackle of the Throg attack he remembered the reason he had been heading into the hills. Of all the men on the Survey team, Shann Lantee had been the least important. The dirty, tedious clean-up jobs, the dull routines which required no technical training but which had to be performed to keep the camp functioning comfortably, those had been his portion. And he had accepted that status willingly, just to have a chance to be included among Survey personnel. Not that he had the slightest hope of climbing up to even an S-E-Three rating in the service. Part of those menial activities had been to clean the animal cages. And there Shann Lantee had found something new, something so absorbing that most of the tiring dull labor had ceased to exist except as tasks to finish before he could return to the fascination of the animal runs. Survey teams had early discovered the advantage of using mutated and highly trained Terran animals as assistants in the exploration of strange worlds. From the biological laboratories and breeding farms on Terra came a trickle of specialized aides-de-camp to accompany man into space. Some were fighters, silent, more deadly than weapons a man wore at his belt or carried in his hands. Some were keener eyes, keener noses, keener scouts than the human kind could produce. Bred for intelligence, for size, for adaptability to alien conditions, the animal explorers from Terra were prized. Wolverines, the ancient "devils" of the northlands on Terra, were being tried for the first time on Warlock. Their caution, a quality highly developed in their breed, made them testers for new territory. Able to tackle in battle an animal three times their size, they should be added protection for the man they accompanied into the wilderness, and their wide ranging, their ability to climb and swim, and above all, their curiosity were assets.
