“Not if you’re human,” said Doug Kellas behind Cal’s shoulder. There was the faintly hostile note in Doug’s voice still. “There could be a dozen different reasons we don’t know anything about. Maybe it’s taboo with them to die inside a spaceship. Maybe he was having hallucinations at the end, that home was just beyond the open end of the ship. Anything.”
Cal did not bother to turn around.
“It’s possible you’re right, Doug,” he said. “They’re about our size physically and their ship was less than half the size of the Harrier. Counting this one in the picture and the three that fell with the one that we killed here, accounts for five of them. But just suppose there were six. And the sixth one hauled the body of this one outside in case we came around for a look—just to give us a false sense of security thinking they were all gone.”
Joe nodded slowly. He put the photos down on the bed and looked at Cal who stood up.
“You’re carrying guns?” said Joe. “You’re all armed in case?”
“We’re starting out with sidearms,” said Cal. “Down here the weight of them doesn’t mean much. But up there…” He nodded to the top reaches of the mountain and did not finish. “But you and John better move inside the ship nights and keep your eyes open in the day.”
“We will.” Joe reached up a hand and Cal shook it. Joe shook hands with the other three who were going. They put their masks on.
“The rest of you ready?” asked Cal, who by this time was already across the bubble enclosure, ready to step out. His voice came hollowly through his mask. The others broke away from Joe and went toward Cal, who stepped through the bubble.
“Wait!” said Joe suddenly from the bed. They turned to him. He lay propped up, and his lips moved for a second as if he was hunting for words. “—Good luck!” he said at last.
“Thanks,” said Cal for all of them. “To you and John, too. We’ll all need it.”
He raised a hand in farewell. They turned and went.
They went away from the ship, up the steep slope of the old glacier stream bed that became more steep as they climbed. Cal was in the lead with Maury, then Jeff, then Doug bringing up the rear. The yellow bright rays of K94 struck back at them from the ice-scoured granite surface of the slope, gray with white veinings of quartz. The warmsuits were designed to cool as well as heat their wearers, but they had been designed for observer-wearers, not working wearers. At the bend-spots of arm and leg joints, the soft interior cloth of the warmsuits soon became damp with sweat as the four men toiled upward. And the cooling cycle inside the suits made these damp spots clammy-feeling when they touched the wearer. The respirator masks also became slippery with perspiration where the soft, elastic rims of their transparent faceplates pressed against brow and cheek and chin. And to the equipment-heavy men the feel of the angle of the steep rock slope seemed treacherously less than eyes trained to Earth gravity reported it. Like a subtly tilted floor in a fun house at an amusement park.
They climbed upward in silence as the star that was larger than the sun of Earth climbed in the sky at their backs. They moved almost mechanically, wrapped in their own thoughts. What the other three thought were personal, private thoughts having no bearing on the moment. But Cal in the lead, his strong-boned, rectangular face expressionless, was wrapped up in two calculations. Neither of these had anything to do with the angle of the slope or the distance to the top of the mountain.
He was calculating what strains the human material walking behind him would be able to take. He would need more than their-grudging cooperation. And there was something else.
He was thinking about water.
Most of the load carried by each man was taken up with items constructed to be almost miraculously light and compact for the job they would do. One exception was the fifteen Earth pounds of components of the Messenger, which Cal himself carried in addition to his mountain-climbing equipment—the homemade crampons, pitons and ice axe-piton hammer—and his food and the sonic pistol at his belt. Three others were the two-gallon containers of water carried by each of the other three men. Compact rations of solid food they all carried, and in a pinch they could go hungry. But to get to the top of the mountain they would need water.
Above them were ice slopes, and the hook-shaped glacier that they had been able to see from the ship below.
That the ice could be melted to make drinking water was beyond question. Whether that water would be safe to drink was something else. There had been the case of another Survey ship on another world whose melted local ice water had turned out to contain as a deposited impurity a small wind-born organism that came to life in the inner warmth of men’s bodies and attacked the walls of their digestive tracts. To play safe here, the glacier ice would have to be distilled.
Again, one of the pieces of compact equipment Cal himself carried was a miniature still. But would he still have it by the time they reached the glacier? They were all ridiculously overloaded now.
Of that overload, only the Messenger itself and the climbing equipment, mask and warmsuit had to be held on to at all costs. The rest could and probably would go. They would probably have to take a chance on the melted glacier ice. If the chance went against them—how much water would be needed to go the rest of the way?
Two men at least would have to be supplied. Only two men helping each other could make it all the way to the top. A single climber would have no chance.
Cal calculated in his head and climbed. They all climbed.
From below, the descending valley stream bed of the former glacier had looked like not too much of a climb. Now that they were on it, they were beginning to appreciate the tricks the eye could have played upon it by sloping distances in a lesser gravity, where everything was constructed to a titanic scale. They were like ants inching up the final stories of the Empire State Building.
Every hour they stopped and rested for ten minutes. And it was nearly seven hours later, with K94 just approaching its noon above them, that they came at last to the narrowed end of the ice-smoothed rock, and saw, only a few hundred yards ahead, the splintered and niched vertical rock wall they would have to climb to the foot of the hook-shaped glacier.

They stopped to rest before tackling the distance between them and the foot of the rock wall. They sat in a line on the bare rock, facing downslope, their packloads leaned back against the higher rock. Cal heard the sound of the others breathing heavily in their masks, and the voice of Maury came somewhat hollowly through the diaphragm of his mask.
“Lots of loose rock between us and that cliff,” said the older man. “What do you suppose put it there?”
“It’s talus,” answered Jeff Ramsey’s mask-hollowed voice from the far end of the line. “Weathering—heat differences, or maybe even ice from snowstorms during the winter season getting in cracks of that rock face, expanding, and cracking off the sedimentary rock it’s constructed of. All that weathering’s made the wall full of wide cracks and pockmarks, see?”
Cal glanced over his shoulder.
“Make it easy to climb,” he said. And heard the flat sound of his voice thrown back at him inside his mask. “Let’s get going. Everybody up!”
