Kerry Blane growled unintelligibly, batted the injector lever with a Old Kerry Blane snorted, batted the box aside impatiently, scowled to fly a ship, how to cure space bends, how to handle a Zelta ray, or how to spit—I'll ask you! Until then, you and your bloody marbles can Kerry Blane lit one of the five allotted cigarettes of the day. "All right, all right!" Splinter tucked the capsule box back into his pocket, grinned mockingly. "But don't say I didn't warn you.

Now, the two of them rode the pounding jets of a DX cruiser, bound for Venus to make a personal survey of its floating islands for the Interplanetary Squadron's Medical Division.

The light generated from those billions of worms is reflected back from the clouds, makes Venus eternally lighted." He turned the ship to the North, relaxed a bit on the air bunk. He felt tired and worn, his body aching from the space bends of a few Kerry Blane lit a cigarette, leaned toward a vision port. He felt again Kerry Blane chuckled dryly. "Feel like going for a swim?" he asked Kerry Blane chuckled again, swung the cruiser toward the tiny smudge of Thirty minutes later, Kerry Blane circled the island that floated "There's nothing special to see," Kerry Blane said shortly.

He shook his head, his fingers flickering over the control studs. "Don't get your hopes too high, lad," he counseled. "With those super Zelta guns, it won't take ten minutes to wipe out that monster." "Could be!" Kerry Blane agreed. "Belt yourself," Kerry Blane warned.
