This one was a roughly carrier shaped creature, but half again as large, built for killing. It had powerful fanged jaws and its eight feet were armed with knifelike, disemboweling claws. As it came at Ed in a lumbering rush, another came crawling out after it.
Ed shot four times, as fast as he could work the action. The heavy slugs did the job, but not quite well enough. With its dying lunge the thing got to him and tossed him ten feet like a rag doll. He lit on his bad hand and felt the wrist bones go.
As he struggled to get up, digging his elbow in and using one hand, he saw a stinger darting in at him. He had lost both the bug gun and his rifle when the fighting unit swiped him. He swiveled on his hips and kicked the stinger away. Then he saw the second fighting unit coming. He forgot about the stinger. It still might get to him, but, if it did, it would be too late to matter.
He drew his knife, managed to get to one knee, and crouched there like an old gray rat, stubbly lips drawn back from worn teeth in a grin of pain and rage. This was one he wasn't going to win, he guessed.
Ten feet away, the fighting unit suddenly ran down like a clockwork toy. It toppled over, skidded past him under its own momentum, and lay there kicking spasmodically. Ed glared at it uncomprehendingly. It arched its neck back to almost touch its haunches, stiffened, and was still.
Ed looked around. The stinger was dead too, three feet from his shoulder, and half a dozen more which had been making for him. A cloud of greasy, stinking smoke was rolling out of the den. The Harn was dead.
Ed put his knife away and lay back. He did not quite pass out, but things got pretty dim.
After a while he got hold of himself and sat up. He was not too surprised to see the man in forest green prodding at the bodies of the fighting units. The stranger looked at the smoke still oozing from the den and nodded approvingly. Then he came over and looked at Ed. He clacked his tongue in concern and bent over, touching Ed's wrist. Ed noticed there was now a cast on it, and it didn't hurt so much. There was also a plastic binding around his ribs and shoulder, where the claws of the first fighter had raked as it tossed him. That was a mighty neat trick, because the rags of his shirt were still buttoned around him, and he was pretty sure it had not been off at any time.
The stranger smiled at Ed, patted him on the shoulder, and disappeared. He seemed to be a busy sort of fellow, Ed thought, with not much time for visiting.
Ed felt quite a bit better now, enough better to gather up what was left of his gear and start home. He was glad to find old Tom waiting for him there. The cat had taken to the woods when the attack on the gate first started, he didn't like shooting, and Ed had worried that the Harn might have got him.
Ed slept till noon the next day, got up and cooked a dozen flapjacks and a pound of bacon. After breakfast, he sat around for an hour or so drinking coffee. Then he spent the rest of the afternoon puttering around the cabin.
He packed away the snakeproof pants, disassembled the flame-thrower, picked up the traps by the hole.
Old Tom seemed to have pretty well cleaned up the mice under the lean-to. Ed took his shovel and filled in the hole he had dug for the cat to get at them.
He went to bed early. Tomorrow he would take a long hike around the new world, scout out the fur and game, plan his trap-line and pick cabin sites.
The next morning, though, the hole into the other world was gone.
The posts which had marked it were sheared neatly in half. The remains of the door still hung there, battered and sagging; but it swung open on nothing but Alaska, when Ed stepped through he found himself standing beside the old leaning birch.
He tried it several times before he convinced himself.
He walked slowly back toward the cabin, feeling old and uncertain, not quite knowing what to do with himself. Old Tom was over by the lean-to, sniffing and pawing tentatively at the fresh earth where Ed had filled in the hole. As Ed came up, he came over to rub against Ed's leg.
They went into the cabin and Ed started fixing breakfast.
