But that was nonsense. Mars was old and worn-out and barren, dreaming itself into slow death. The tramp of human feet, shouts of men and roar of sky-storming rockets, were waking it, but to a new destiny, to man's. When Ares lifted its hard spires above the hills of Syrtis, where then were the ancient gods of Mars?
It was cold, and the cold deepened as the night wore on. The stars were fire and ice, glittering diamonds in the deep crystal dark. Now and then he could hear a faint snapping borne through the earth as rock or tree split open. The wind laid itself to rest, sound froze to death, there was only the hard clear starlight falling through space to shatter on the ground.
Once something stirred. He woke from a restless sleep and saw a small thing skittering toward him. He groped for the rifle beside his sleeping bag, then laughed harshly. It was only a sandmouse. But it proved that the Martian had no chance of sneaking up on him while he rested.
He didn't laugh again. The sound had echoed too hollowly in his helmet.
With the clear bitter dawn he was up. He wanted to get the hunt over with. He was dirty and unshaven inside the unit, sick of iron rations pushed through the airlock, stiff and sore with exertion. Lacking the hound, which he'd had to shoot, tracking would be slow, but he didn't want to go back to Port Armstrong for another. No, hell take that Martian, he'd have the devil's skin soon!
Breakfast and a little moving made him feel better. He looked with a practiced eye for the Martian's trail. There was sand and brush over everything, even the rocks had a thin coating of their own erosion. The owlie couldn't cover his tracks perfectly—if he tried, it would slow him too much. Riordan fell into a steady jog.
Noon found him on higher ground, rough hills with gaunt needles of rock reaching yards into the sky. He kept going, confident of his own ability to wear down the quarry. He'd run deer to earth back home, day after day until the animal's heart broke and it waited quivering for him to come.
The trail looked clear and fresh now. He tensed with the knowledge that the Martian couldn't be far away.
Too clear! Could this be bait for another trap? He hefted the rifle and proceeded more warily. But no, there wouldn't have been time—
He mounted a high ridge and looked over the grim, fantastic landscape. Near the horizon he saw a blackened strip, the border of his radioactive barrier. The Martian couldn't go further, and if he doubled back Riordan would have an excellent chance of spotting him.
