During the early weeks he had found a thick loose-leaf binder in the back of one of the desk drawers. He thought it might have been left there intentionally. Its heading was NOTES ON THE TERRESTRIAL ECOLOGICAL BASE OF THE EIGHTEENTH SYSTEM, VOLUME III. After leafing through them once, it had been a while before Barney could bring himself to study the notes in more detail. He didn't, at that time, want to know too much about the situation he was in. He was still numbed by it.
But eventually he went over the binder carefully. The various reports were unsigned, but appeared to have been compiled by at least four or five persons—McAllen among them; his writing style was not difficult to recognize. Leaving out much that was incomprehensible or nearly so, Barney could still construe a fairly specific picture of the association project of which he was now an unscheduled and unwilling part. Selected plants and animals had been moved from Earth through the McAllen Tube to a world consisting of sand, rock and water, without detected traces of indigenous life in any form. At present the Ecological Base was only in its ninth year, which meant that the larger trees in the valley had been nearly full-grown when brought here with the soil that was to nourish them. From any viewpoint, the planting of an oasis of life on the barren world had been a gigantic undertaking, but there were numerous indications that the McAllen Tube was only one of the array of improbable devices the association had at its disposal for such tasks. A few cryptic paragraphs expressed the writer's satisfaction with the undetailed methods by which the Base's localized climatic conditions were maintained.
So far even the equipment which kept the cabin in uninterrupted operation had eluded Barney's search. It and the other required machinery might be buried somewhere in the valley. Or it might, he thought, have been set up just as easily some distance away, in the desert or among the remotely towering mountain ranges. One thing he had learned from the binder was that McAllen had told the truth in saying no one could contact him from Earth before the full period of his exile was over. The reason had seemed appalling enough in itself. This world had moved to a point in its orbit where the radiance of its distant sun was thickening between it and Earth, growing too intense to be penetrated by the forces of the McAllen Tube. Another four years would pass before the planet and the valley emerged gradually from behind that barrier again.
He walked, rested, walked again. Now and then he was troubled by a burst of violent sweating, followed by shivering fits until his clothes began to dry again. The big moon edged presently over the ridge above him, and in the first flood of its light the opposite slope of the valley took on the appearance of a fanciful sub-oceanic reef. The activity of the animal life about Barney increased promptly. It was no darker now than an evening hour on Earth, and his fellow occupants of the Ecological Base seemed well-adjusted to the strange shifts of day and night to which they had been consigned.
He pushed through a final thicket of shrubbery, and found himself at the edge of the lake. Beyond the almost circular body of water, a towering wall of cliffs sealed the upper end of the valley. He had come almost a mile, and while a mile—a city mile, at least—wouldn't have meant much to Barney Chard at one time, he felt quite exhausted now. He sat down at the edge of the water, and, after a minute or two, bent forward and drank from it. It had the same cold, clear flavor as the water in the cabin.
The surface of the water was unquiet. Soft-flying large insects of some kind were swarming about, stippling the nearby stretch of the lake with their touch, and there were frequent swift swirls as fish rose from beneath to take down the flyers. Presently one of them broke clear into the air—a big fish, thick-bodied and shining, looking as long as Barney's arm in the moonlight—and dropped back with a splash. Barney grinned twistedly. The NOTES indicated Dr. McAllen had taken some part in stocking the valley, and one could trust McAllen to see to it that the presence of his beloved game fish wasn't overlooked even in so outlandish a project.
He shifted position, became aware of the revolver in his pocket and brought it out. A wave of dull anger surged slowly through him again. What they did with trees and animals was their own business. But what they had done to a human being....
He scrambled suddenly to his feet, drew his arm back, and sent the gun flying far out over the lake. It spun through the moonlight, dipped, struck the surface with less of a splash than the fish had made, and was gone.
Now why, Barney asked himself in amazement, did I do that? He considered it a moment, and then, for the first time in over a year, felt a brief touch of something not far from elation.
