Niobe, like Niobe, was all tears--a world of rain falling endlessly from an impenetrable overcast, fat wet drops that formed a grieving background sound that never ceased, sobbing with soft mournful noises on the rubbery broadleaves, crying with obese splashes into forest pools, blubbering with loud, dismal persistence on the sounding board of his helmet. And on the ground, the raindrops mixed with the loesslike soil of the trail to form a gluey mud that clung in huge pasty balls to his boots. Everywhere there was water, running in rivulets of tear-streaks down the round cheeks of the gently sloping land--rivulets that merged and blended into broad shallow rivers that wound their mourners' courses to the sea. Trekking on Niobe was an amphibious operation unless one stayed in the highlands--a perpetual series of fords and river crossings. And it was hot, a seasonless, unchanging, humid heat that made a protection suit an instrument of torture that slowly boiled its wearer in his own sweat. But the suit was necessary, for exposed human flesh was irresistible temptation to Niobe's bloodsucking insects. Many of these were no worse than those of Earth, but a half dozen species were deadly. The first bite sensitized. The second killed--anaphylactic shock, the medics called it. And the sith was one of the deadly species. Lanceford shrugged fatalistically. Uncomfortable as a protection suit was, it was better to boil in it than die without it. He looked at Kron squatting beside the trail and envied him. It was too bad that Earthmen weren't as naturally repellent to insects as the dominant native life. Like all Niobians, the native guide wore no clothing--ideal garb for a climate like this. His white, hairless hide, with its faint sheen of oil, was beautifully water-repellent. Kron, Lanceford reflected, was a good example of the manner in which Nature adapts the humanoid form for survival on different worlds. Like the dominant species on every intelligent planet in the explored galaxy, he was an erect, bipedal, mammalian being with hands that possessed an opposable thumb. Insofar as that general description went, Kron resembled humanity--but there were differences. * * * * * Squatting, the peculiar shape of Kron's torso and the odd flexibility of his limbs were not apparent. One had the tendency to overlook the narrow-shouldered, cylindrical body and the elongated tarsal and carpal bones that gave his limbs four major articulations rather than the human three, and to concentrate upon the utterly alien head.
