Ewen felt reluctant to see him go. "What shall I do if Zabal dies?"
"Bury him," MacAran said harshly, "what else?" He turned away and motioned to Camilla. "Let's go, Lieutenant."
They strode away from the clearing without looking back, MacAran setting a steady pace, not too fast, not too slow.
As they climbed higher the land changed, the ground under foot becoming less overgrown, with more bare rocks and sparser trees. The slope of the foothills was not acute, but as they neared the crest of the slope where they had camped, MacAran called a halt to rest and swallow a mouthful of rations. From where they stood they could see the small orange square of the shelter tent, only a flyspeck at this height, through the heavy trees.
"How far have we come, MacAran?" the woman asked, putting back the fur-lined hood of her jacket.
"I've no way of knowing. Five, six miles perhaps; about two thousand feet of altitude. Headache?"
"Only a little," the girl lied.
"That's the change in air pressure; you'll get used to it presently," he said. "Good thing we have a fairly gradual rise in land."
"It's hard to realize that's really where we slept last night--so far down," she said a little shakily.
"Over this ridge it will be out of sight. If you want to chicken out, this is your last chance. You could make it down in an hour, maybe two."
She shrugged. "Don't tempt me;"
"Are you frightened?"
"Of course. I'm not a fool. But I won't panic, if that's what you mean."
MacAran rose to his feet, swallowing the last of his ration. "Let's go, then. Watch your step--here are rocks above us."
But to his surprise she was sure-footed on the piled rocks near the peak, and he did not need to help her,or hunt for an easier pass. From the top of the hill they could see a long panorama beneath them, behind them; the valley where they had camped, with its long plain, the further valley where the starship lay--although even with his strong binoculars MacAran could only make out a tiny dark streak that might be the ship. Easier to see was the ragged clearing where they had cut trees for shelters. Passing the glasses to Camilla, he said, "Man's fast mark on a new world."
"And last, I hope," she said. He wanted to ask her, put it up to her straight, could the ship be repaired? But that wasn't the time for thinking about that. He said, "There are streams among the rocks, and Judy tested the water days ago. We can probably find all the water we need to refill our canteens, so don't ration yourself too much."
"My throat feels terribly dry. Is it just the altitude?"
"Probably. On Earth we couldn't come much higher than this without oxygen, but this planet has a higher oxygen content." MacAran took one last look at the orange tent below them; stowed the glasses and slung them over his shoulder. "Well, the next peak will be higher. Let's get on, then." She was looking at some small orange flowers that grew in the crannies of the rock. "Better not touch them. Who knows what might bite, here?"
She turned around, a small orange flower in her fingers. "Too late now;" she said with wry grin. "If I'm going to drop dead when I pick a flower, better find it out now than later. I'm not so sure I want to go on living if it's a planet where I can't touch anything." She added, more seriously, "We've got to take some risks, Rafe--and even then, something we never thought of might kill us. Seems to ma that all we can do is take the obvious precautions--and then take our chances."
It was the first time since the crash that she had called him by his first name, and unwillingly he softened. He said, "You're right of course; short of going around in space suits we haven't any real protection, so there's no point in being paranoid. If we were a First Landing Team we'd know what risks not to take, but as it is I guess all we can do is take our chances:" It was growing hot, and he stripped off his outer layer of clothing. "I wonder how much stock to put in Heather's premonitions of bad weather?"
They started down the other side of the ridge.
Halfway down the slope, after two or three hours of searching for a path, they discovered a small crystal spring gushing from a split rock, and refilled their canteens; the water tasted sweet and pure, and at MacAran's suggestion they followed the stream down; it would certainly take the shortest way.
At dusk heavy clouds began to scud across the lowering sun. They were in a valley, with no chance to signal the ship or the other camp of their party. While they were setting up the tiny shelter-tent, and MacAran was making fire to heat their rations, a thin fine rain began falling; swearing, he moved the small fire under the flap of the tent, trying to shield it a little from the rain. He managed to get water heated, but not hot, before the gusting sleet put it out again, and he gave up and dumped the dried rations into the barely warm water. "Here. Not tasty but edible--and nourishing, I hope."
Camilla made a face when she tasted it, but to his relief said nothing. The sleet whipped around them and they crawled inside and drew the flap tight. Inside there was barely room enough for one of them to lie at full length while the other sat up--the emergency tents were really only meant for one. MacAran started to make some flippant remark about nice cozy quarters, looked at her drawn face and didn't. He only said, as he wriggled out of his storm parka and pack, and started unrolling his sleeping bag, "I hope you don't suffer from claustrophobia:"
"I've been a spaceship officer since I was seventeen. How could I get along with claustrophobia?" In the dark he imagined her smile. "On the contrary."
Neither of them had much to say after that. Once she asked into the darkness, "I wonder how Marco is?" but MacAran had no answer for her, and there was no point in thinking how much better this trip would have been with Marco Zabal's knowledge of the high Himalaya. He did ask, once, just before he dropped off to sleep, "Do you want to get up and try for some star-sights before dawn?"
"No. I'll wait for the peak, I guess, if we get that far:" Her breathing quieted into soft exhausted sighs and he knew she slept. He lay awake a little, wondering what lay ahead. Outside, the sleet lashed the branches of the trees and there was a rushing sound which might have been wind or some animal making a rush through the undergrowth. He slept lightly, alert for unexpected sounds. Once or twice Camilla cried out in .her sleep and he woke, alert and listening. Had she a touch of altitude sickness? Oxygen content or no oxygen content, the peaks were pretty high and each successive one left their general altitude a little higher. Well, she'd get acclimated, or else she wouldn't. Briefly, on the edge of sleep, MacAran reflected that it was the stuff of entertainment---media, a man alone with a beautiful woman on a strange planet full of dangers. He was conscious of wanting her--hell, he was human and male--but in their present circumstances nothing was further from his mind than sex. Maybe I'm just too civilized. In the very thought, exhausted by the day's climbing, he fell asleep.
The next three days were replays of that day, except that on the third night they reached a high pass at dusk and the night's rain had not yet begun. Camilla set up her telescope and made a few observations. He could not forbear, as he set up the shelter-tent in the dark, to ask, "Any luck? Where are we, do you know?"
"Not sure. I knew already that this sun is none of the charted ones, and the only constellations I can spot, from central co-ordinates, are all skewed to the left. I suspect we're right out of the Spiral Arm of the Galaxy--note how few stars there are, compared even to Earth, let alone any centrally located colony planet! Oh, we're a good long way from where we were supposed to be going!" Her voice sounded taut and drawn, and as he moved closer he saw in the darkness that there were tears on her cheeks.
He felt a painful urge to comfort her. "Well, at least when we're on our way again, we'll have discovered a new habitable planet. Maybe you'll even get part of the finder's fee."
