Cat and Mouse Part 1

Cat and Mouse.

by Ralph Williams.

_The Warden needed to have a certain very obnoxious pest eliminated ... and he knew just the pest-eradicator he needed...._

_The Harn first came to the Warden's attention through its effect on the game population of an area in World 7 of the Warden's sector. A natural ecology was being maintained on World 7 as a control for experimental seedings of intelligent life-forms in other similar worlds. How the Harn got there, the Warden never knew. In its free-moving larval state, the Harn was a ticklike creature which might have sifted through a natural inter-dimensional rift; or it might have come through as a hitchhiker on some legitimate traveler, possibly even the Warden himself._

_In any event, it was there now. Free of natural enemies and compet.i.tion, it had expanded enormously. So far, the effect in the control world was localized, but this would not be the case when the Harn seeded. Prompt action was indicated._

_The Warden's inclination and training was in the direction of avoiding direct intervention in the ecology of the worlds under his jurisdiction, even in the field of predator control. He considered introduction of natural enemies of the Harn from its own world, and decided against it. That cure was as bad, if not worse, than the disease itself._

_There was, however, in one adjacent world, a life-form not normally a.s.sociated with the Harn; but which a.n.a.lysis indicated would be inimical to it, and reasonably amenable to control._

_It was worth trying, anyway._

October 3rd, Ed Brown got up to the base cabin of his trap line with his winter's outfit.

He hung an N. C. Company calendar on the wall and started marking off the days.

October 8th, the hole into the other world opened.

In the meantime, of course, Ed had not been idle. All summer the cabin had stood empty. He got his bedding, stove, and other cabin gear down from the cache and made the place livable. The mice were thick, a good fur sign, but a nuisance otherwise. Down in the cellar hole, when he went to clear it out for the new spud crop, he found burrowings everywhere.

Well, old Tom would take care of that in short order. Tom was a big, black, bobtailed cat eleven years old who had lived with Ed since he was a kitten. Not having any feline companions.h.i.+p to distract him, his only interest was hunting mice. Generally he killed a lot more than he could eat, racking the surplus in neat piles beside the trail, on the doorstep, or on a slab in the cellar. He was the best mouser in interior Alaska.

Ed propped the cellar hatch with a stick so old Tom could come and go as he pleased, and went on about his ch.o.r.es, working with a methodical efficiency that matched Tom's and went with his thinning gray hair and forty years in the woods. He dug the spuds he had planted that spring.

He made a swing around his beaver lakes, tallying the blankets in each house. He took the canoe and moved supplies to his upper cabin. He harvested some fat mallards that had moved down on the river with the coming of skim ice on the lakes. He bucked up firewood and stacked it to move into camp with the first snow.

On the fifth morning, as he was going down to the boat landing with a pail for water, he found the hole into the other world.

Ed had never seen a hole into another world, of course, nor even heard of such a thing. He was as surprised as any one would naturally be to find one not fifty feet from their front door.

Still, his experience had been all in the direction of believing what his eyes told him. He had seen a lot of strange things in his life, and one more didn't strain him too much. He stood stockstill where he had first noticed the hole and studied it warily.

It was two steps off the trail to the left, right beside the old leaning birch, a rectangular piece of scenery that did not fit. It looked to be, as nearly as he could judge, about man-size, six by three. At the bottom it was easy enough to see where this world left off and that one began. On the left side the two worlds matched pretty well, but on the right side there was a n.i.g.g.e.rhead in this world, the moss-covered relic of a centuries old stump, while that world continued level, so that the n.i.g.g.e.rhead was neatly sliced in two. Also, the vegetation was different, mossy on this side, gra.s.sy on that.

On up around the hole, though, it was harder to tell. There was no clear-cut line, just the difference in what you could see through it. In the other world, the ground seemed to fall away, with low scrubby brush in the foreground. Then, a mile or so away, there were rising hills with hardwood forests of some kind, still green with summer, covering them.

Ed stepped cautiously to one side. The view through the hole narrowed, as if it faced the trail squarely. He edged around the old birch to get behind it, and from that side there was no hole, just the same old Alaskan scenery, birch and rose bushes and spruce. From the front, though, it was still there.

He cut an alder shoot about eight feet long, trimmed it, and poked it through the hole. It went through easily enough. He prodded at the sod in the other world, digging up small tufts. When he pulled the stick back, some of the other world dirt was on the sharp end. It looked and smelled just about like any dirt.

Old Tom came stretching out into the morning sun and stalked over to investigate. After a careful inspection of the hole he settled down with his paws tucked under him to watch. Ed took a flat round can from his pocket, lined his lip frugally with snuff, and sat down on the up-ended bucket to watch too. At the moment, that seemed the likeliest thing to do.

_It was nearly swarming time, the Harn had many things to preoccupy it, but it spared one unit to watch the hole into the other world. So far, nothing much had happened. A large biped had found the opening from the other side. It had been joined by a smaller quadruped; but neither showed any indication yet of coming through. The sun was s.h.i.+ning through the hole, a large young yellow sun, and the air was crisp, with sharp interesting odors._

_The biped ejected a thin squirt of brown liquid through the hole--venom of some sort, apparently. The Harn hastily drew back out of range._

The hole into the other world stayed there, as un.o.btrusively fixed as if it had been there since the beginning of time. Nothing came through, and nothing moved in the other world but leaves stirring now and then with a breeze, clouds drifting across the sky. Ed began to realize it was getting late in the morning, and he had not yet had breakfast. He left old Tom to watch the hole, got stiffly to his feet and went on down the trail to get the pail of water he had started for. From the cabin door, he could still see the hole into the other world. He kept one eye on it while he cooked breakfast.

As he was finis.h.i.+ng his second cup of coffee, he noticed the view into the other world becoming duller, dimming in a peculiar fas.h.i.+on. He left the dirty dishes and went over to look more closely. What was happening, he found, was just that it was getting dark in the other world. The effect was strange, much like looking out the door of a brightly lighted room at dusk. The edges of the hole cast a very clearly marked shadow now, and outside this shaft of sunlight the view faded, until a few yards away it was impossible to make out any detail.

Presently the stars came out. Ed was not an astronomer, but he had a woodsman's knowledge of the sky. He could find nothing familiar in any of the stars he saw. In some way, that was more unsettling than the hole itself had been.

After he had finished the dishes, he cut two gee-pole spruce, trimmed them, and stuck one on each side of the hole. He got some thin thread he used to tie beaver snares and wove it back and forth between the poles, rigging a tin can alarm. It seemed likely someone or something had put the hole there, it had not just happened. If anything came through, Ed wanted to know about it. Just to make extra sure, he got some number three traps and made a few blind sets in front of the hole.

Then he went back to his ch.o.r.es. Whatever was going to happen with the hole would happen when it happened, and winter was still coming.

He set some bab.i.+.c.he to soak for mending his snowshoes. He ran the net he had set at the edge of the eddy for late silvers and took out two fish.

Old Tom had pretty well cleaned up the mice in the cellar hole, but they were still burrowing around the sills of the lean-to. Ed took a shovel and opened up a hole so Tom could get under the lean-to floor. He got out his needles, palm, thread, and wax; and mended his winter moccasins.

Off and on, he checked the hole into the other world. There was nothing but the slow progression of alien stars across the sky. Finally old Tom grew bored and left to investigate the hole under the lean-to. Shortly there were scutterings and squeakings as evidence that he, too, had got back to business.

Toward evening, Ed got to wondering how a living creature would take transition into the other world. He had no intention of trying it himself until he knew a lot more about it, but he thought he might be able to scare up a surrogate. Out by the wood pile some live-traps were piled under a spruce, from the time when Ed had been catching marten for the Fish and Wildlife to transplant. One was still in pretty fair shape.

He patched it up and set it among the cottonwoods at the head of the bar, where there were some rabbit trails.

When he went to bed it was still dark in the other world. He left the cabin door ajar so he could see it from his bed and set his shotgun, loaded with 00 buck, handy.

Nearing sixty, Ed was not a sound sleeper, even when he had nothing on his mind. About ten it started to get light in the other world, and that woke him up. He padded out to look, but there was no change, it looked about the same as yesterday. He went back to bed.

The next morning there was a rabbit in the live-trap. With a pole, Ed pushed the trap with the rabbit in it through into the other world and watched. Nothing happened. After a while the rabbit began nibbling at some spears of gra.s.s that pushed through the wire of the cage. Ed pulled it back and examined the rabbit carefully. It seemed healthy and about as happy as a rabbit could expect to be in a cage.

It did not get dark in the other world till about noon, that day; and about seven, when it was dark in both worlds, Ed heard the jangle of the tin can alarm, followed by the snap of one of the steel traps.

He took a flashlight and found a small hoofed animal, hardly bigger than old Tom, rearing and bucking with a broken leg in the trap. It had sharp little spike horns, only a few inches long, but mean. Ed got several painful jabs before he got the animal tied up and out of the trap. He restrung the alarm, then took his catch into the cabin to examine.

It was herbivorous and adult, from the looks of its teeth and hoofs, though it only weighed about fifteen pounds. As an approximation, Ed decided it was female. When he killed it and opened it up, at first glance it looked reasonably familiar, on closer study less so.

The blood, anyway, was red; not blue or yellow or green; and the bones were bones, just odd-shaped.

Ed cut off a slice of heart and tossed it to old Tom. The cat sniffed it dubiously and then decided he liked it. He meowed for more. Ed gave it to him and fried a small sliver of ham. It smelled and tasted fine, but Ed contented himself with a single delicate nibble, pending further developments. Anyway, it was beginning to look like a little exploration would be feasible.

_The Harn, also, was well-satisfied with the way things were going. It had been a strain to pa.s.s up the juicy little quadruped in the cage, but the inhabitants of the other world seemed shy, and the Harn did not wish to frighten them. At least, it knew now that life could come through the hole, and the small herbivore it had herded through confirmed that pa.s.sage in the opposite direction was equally possible--plus a gratis demonstration of the other world's pitiful defenses. At swarming time, the whole new world would be open to embryo Harn, as well as this world it presently occupied._

_It looked like a really notable swarming. The Harn budded three more planters on the forcing stem, to be ready to take full advantage of it._

It got light in the other world at one in the morning that night. Ed had the days there pretty well pegged now. They were roughly twenty-seven hours, of which about thirteen hours were dark. Not too high a lat.i.tude, apparently, and probably late summer by the looks of the vegetation.
