"Splinter" Wood grinned. Kerry Blane growled unintelligibly, batted the injector lever with a Splinter rolled his six foot three of lanky body into a more comfortable position on the air-bunk. He yawned tremendously, fumbled a small box from his shirt pocket, and removed a marble-like capsule. Old Kerry Blane snorted, batted the box aside impatiently, scowled "Tsk! Tsk! Tsk!" Splinter reached out lazily, plucked the capsules from the air, one by one. Kerry Blane lit one of the five allotted cigarettes of the day. Kerry Blane made a rich, ripe noise with his mouth. "Pfuii!" he said very distinctly. "Gracious!" Splinter said in mock horror. They made a strange contrast as they lay in their air bunks. Splinter was fully a head taller than the dour Irishman, and his lanky build gave a false impression of awkwardness.

Interplanetary Squadron's Medical Division. "Ten to one we don't get back!" Splinter said pessimistically. Kerry Blane scrubbed out his cigarette, scowled bleakly at the instrument panel. He sensed the faint thread of fear in the youngster's tone, and a nostalgic twinge touched his heart, for he was remembering ?" Kerry Blane choked loosened collar. "Of course!" Splinter grinned. Kerry Blane exploded, words spewing volcanically forth. Splinter relaxed, his booted foot beating out a dull rhythm to the colorful language learned through almost fifty years of spacing. And at last, when Kerry Blane had quieted until he but smoldered, he leaned over and beamed. "Some day you can teach them to me." They laughed then, Old Kerry Blane and young Splinter Wood, and the warmth of their friendship was a tangible thing in the small control-room of the cruiser. for seconds. He swallowed three capsules automatically, passed into a coma-like sleep, woke hours later to stare clear-eyed into Splinter's concerned face. "Close enough!" Splinter agreed relievedly. "If you had followed my Kerry Blane grinned, winced when he felt the dull ache in his body. Kerry Blane nodded in silent approval. Kerry Blane yawned, settled back luxuriously. "I'll tell you later," he Splinter Wood watched breathlessly from the vision port, his long face Kerry Blane glanced tolerantly at his young companion, felt a nostalgic demarcation between the sunward and sunless sides of the planet. He hummed tunelessly, strangely happy, as he peered ahead. "Val Kenton died there," Splinter whispered softly, "Died to save the lives of three other people!" Kerry Blane nodded. "Yes," he agreed, and his voice changed subtly. Splinters shivered slightly. "Do you think we'll find it?" he asked. Kerry Blane nodded. "I think it will find us after all, it's just an an integral part of the ship. Splinter Wood watched him with awe in his eyes, seeing for the first time the incredible instinct that had made Kerry Blane the idol of a billion people. He relaxed visibly, all instinctive fear allayed by the tossed in a majestic display of ruthless strength an ocean that seemed to be composed of liquid fluorescence. Kerry Blane heard Splinter's instant sigh of unbelief. "Good Lord!" Splinter said, "What—" His voice stilled, and he was silent, his eyes drinking in the weird Splinter turned a wondering face. "But the official reports say that Kerry Blane nodded. "That was merely a pretext to keep foolhardy Kerry Blane lit a cigarette, leaned toward a vision port. He felt again "Brrrr!" Splinter shivered in sudden horror. Kerry Blane chuckled dryly. "Feel like going for a swim?" he asked conversationally. Splinter shook his head, watched the scene disappear from view to the Kerry Blane chuckled again, swung the cruiser toward the tiny smudge of "I don't see anything suspicious," Splinter contributed. "There's nothing special to see," Kerry Blane said shortly. "As I now and then, to the lanky Splinter who scowled moodily and toyed with the dis-gun in his long hands. "Cheer up, lad," Kerry Blane said finally. "I think you'll find plenty to occupy your time shortly." "Maybe?" Splinter said gloomily. the snoring Splinter. "Huh? Whuzzat?" Splinter grunted, rolled to his elbow. Splinter rubbed his hands together, sighed like a boy seeing his first "Right!" Splinter's fingers were all thumbs in his excitement. Kerry Blane set the controls for a shallow glide, his fingers moving Kerry Blane said absolutely nothing, his breath driven from him by the Splinter Wood laughed, almost hysterically, mopped at his forehead with Kerry Blane moved his arm experimentally, felt broken bones grate in Splinter looked up from his task of bandaging his leg. "What caused "Those gol-damned pills you been taking caused the crash!" he roared. "One of them broke and shorted out the control board." He scowled at the incredulous Splinter.

After a bit, Kerry Splinter nodded, opened the medical locker, worked with tape and splints for minutes. Great beads of perspiration stood out in high relief on Kerry Blane's forehead, but he made no sound. At last, Splinter finished, tucked the supplies away. Splinter Wood was silent, awed by the beauty and the tremendous size of there was no hissing crackle of released energy. Kerry Blane strode forward, puzzlement on his lined face, his hand out-stretched toward the defective weapon. Splinter gaped at the gun in his hands, held it out wordlessly. "The crash must have broken something," Kerry Blane said slowly. Splinter shook his head. "There's only one moving part," he said, "and that's the force gate on the firing stud." Splinter lifted the second gun, pressed the stud, gazed white-faced at Old Kerry Blane dropped the first gun to his side, swore harshly.
