"Do you notice what seems to be a sort of shifting movement?" he asked Burl. Burl looked, and sure enough, he saw that in places there seemed a flickering of lights. "Yes," he said, "I see it. What do you suppose it is?" "I don't know," said Russ, "But I'm going to ask Lockhart to put the ship down and let me take a look." Lockhart at first demurred, but finally decided that they could afford the brief halt. The _Magellan_ approached the surface, safely distant from the Sun-tap station. Burl and Russ descended in the two-man rocket plane, while the teardrop-shaped ship hung half a mile above them. They landed on a narrow plain, bordered by low ridges of mountains shining with streaks of frozen hydrogen. A layer of cosmic dust hung over the rocks. Wearing insulated space suits, they left the rocket plane. It was Burl who made the first discovery. He pointed dramatically at the ground. "Look, Russ. This dust is full of streaks and marks. It hasn't been lying here undisturbed. Something has crossed over it!" Russ kneeled in order to look more carefully. The layer of dust, the consequences of an airless world exposed without protection to the endless fall of cosmic particles, was indeed not the level, undisturbed surface it should have been. Here and there were light, low depressions, as if something had moved across it--like a small snake crawling on its belly. In one place lay a series of depressions, like the footprints of some light-bodied creature. "Impossible," muttered Russ. "Life can't exist here." But they trudged on, across the barren flat to a ridge of rock. Here they found what they had thought to be impossible. Clustered along the side of the ridge, in the faint light of the distant and tiny Sun, was a series of thin, blue stalks, about half a foot in height. On each stalk was a flat scalloped top like a little umbrella. It was sometimes bright blue, and sometimes violet. As they drew nearer, these little stalks began to sway, and turned their tops toward them. "They look like plants," said Burl. "Plants made of something glassy and plastic." As Russ studied the strange growths, something moved across the dusty tract behind them. It was long and thin and wiggly, with a ridge of tiny crystalline hairs along its back. It was like a snake perhaps, but one made of some unbelievably delicate glasswork. It slid among the plants and wrapped itself around one. The growth snapped suddenly, and then was absorbed by the creature. Russ shook his head in amazement. "This is a great discovery," he said incredulously. "This is life! It's life of a chemical type utterly different from the protoplasm of Earth and Mars and Venus. It's life designed to exist among liquid gases and frozen air--life which can't have anything in common with protoplasm. Apparently it couldn't exist even on Saturn's moons--they were too _hot_ for it!"
