I looked around a couple of times and that sinuous creature was still behind me. He wasn’t gaining on me any, although I had the feeling that he could if he put his mind to it. Matter of fact, he didn’t seem to be following me alone. He was doing a lot of weaving back and forth. He reminded me of nothing quite so much as a faithful farm dog bringing in the cattle. But even thinking this, it took me a little time to realize that was exactly what he was - an old farm dog bringing in a bunch of assorted dinosaurs and one misplaced human being. At the bottom of the hill I looked back again and now that I could see the whole slope of the hill, I saw that this was a bigger cattle drive than I had imagined. The entire hill was alive with running beasts and behind them were a half dozen of the pinkish dogs.
And I knew when I saw this that the moving herds I’d seen out on the valley floor were not migratory herds, but they were moving because they were being driven - that this was a big roundup of some sort, with all the reptiles and the dinosaurs and myself being driven to a common center.
I knew that my life depended on getting lost somehow, and being left behind. I had to find a place to hide and I had to dive into this hiding place without being seen. Only trouble was there seemed no place to hide. The valley floor was naked and nothing bigger than a mouse could have hidden there.
Ahead of me a good-size swale rose up from the level floor and I went pelting up it. I was running out of wind. My breath was getting short and I had pains throbbing in my chest and I knew I couldn’t run much farther.
I reached the top of the swale and started down the reverse slope. And there, right in front of me, was a bush of some sort, three feet high or so, bristling with thorns. I was too close to it and going too fast to even try to dodge it, so I did the only thing I could - I jumped over it.
But on the other side there was no solid ground. There was, instead, a hole. I caught just a glimpse of it and tried to jerk my body to one side, and then I was falling into the hole.
It wasn’t much bigger than I was. It bumped me as I fell and I picked up some bruises, then landed with a jolt. The fall knocked the breath out of me and I was doubled over, with my arms wrapped about my belly.
My breath came slowly back and the pain subsided and I was able to take a look at where I was.
The hole was some three feet in diameter and perhaps as much as seven deep. It slanted slightly toward the forefront of the slope and its sides were worn smooth. A thin trickle of dirt ran down from the edge of it, soil that I had loosened and dislodged when I had hit the hole. And about halfway up was a cluster of small rocks, the largest of them about the size of a human head, projecting more than half their width out of the wall. I thought, idly, as I looked at them, that some day they’d come loose and drop into the hole. And at the thought I squirmed around a little to one side, so that if they took a notion to fall I’d not be in the line of fire.
Looking down, I saw that I’d not fallen to the bottom of the hole, for the hole went on, deeper in the ground. I had come to rest at a point where the hole curved sharply, to angle back beneath the swale top.
I hadn’t noticed it at first, I suppose because I had been too shook up, but now I became aware of a musky smell. Not an overpowering odor, but a sort of scent - faintly animal, although not quite animal.
A smooth-sided hole and a musky smell - there could be no other answer: I had fallen not into just an ordinary hole, but into a burrow of some sort. And it must be the burrow of quite an animal, I thought, to be the size it was. It would have taken something with hefty claws, indeed, to have dug this sort of burrow.
And even as I thought it, I heard the rattling and the scrabbling of something coming up the burrow, no doubt coming up to find out what was going on.
I did some scrabbling myself. I didn’t waste no time. But about three feet up I slipped. I grabbed for the top of the hole, but my fingers slid through the sandy soil and I couldn’t get a grip. I shot out my feet and stopped my slide short of the bottom of the hole. And there I was, with my back against one side of the hole and my feet braced against the other, hanging there, halfway up the burrow.
While all the time below me the scrabbling and the clicking sounds continued. The thing, whatever it might be, was getting closer, and it was coming fast.
Right in front of me was the nest of rocks sticking from the wall. I reached out and grabbed the biggest one and jerked and it came loose. It was heavier than I had figured it would be and I almost dropped it, but managed to hang on.
A snout came out of the curve in the burrow and thrust itself quickly upward in a grabbing motion. The jaws opened up and they almost filled the burrow and they were filled with sharp and wicked teeth.
I didn’t think. I didn’t plan. What I did was instinct. I dropped the rock between my spread-out legs straight down into that gaping maw. It was a heavy rock and it dropped four feet or so and went straight between the teeth, down into the blackness of the throat. When it hit it splashed and the jaws snapped shut and the creature backed away.
How I did it, I don’t know, but I got out of the hole. I clawed and kicked against the wall and heaved my body up and rolled out of the hole onto the naked hillside.
Naked, that is, except for the bush with the inch-long thorns, the one that I’d jumped over before I fell into the burrow. It was the only cover there was and I made for the upper side of it, for by now, I figured, the big cattle drive had gone past me and if I could get the bush between myself and the valley side of the swale, I might have a chance. Otherwise, sure as hell, one of those dogs would see me and would come out to bring me in.
For while there was no questions that they were dinosaur herders, they probably couldn’t tell the difference between me and a dinosaur. I was alive and could run and that would qualify me.
There was always the chance, of course, that the owner of the burrow would come swarming out, and if he did I couldn’t stay behind the bush. But I rather doubted he’d be coming out, not right away, at least. It would take him a while to get that stone out of his throat.
I crouched behind the bush and the sun was hot upon my back and, peering through the branches, I could see, far out on the valley floor, the great herd of milling beasts. All of them had been driven together and there they were, running in a knotted circle, while outside the circle prowled the pinkish dogs and something else as well - what appeared to be men driving tiny cars. The cars and men were all of the same color, a sort of greenish gray, and the two of them, the cars and men, seemed to be a single organism. The men didn’t seem to be sitting in the cars; they looked as if they grew out of the cars, as if they and the cars were one. And while the cars went zipping along, they appeared to have no wheels, It was hard to tell, but they seemed to travel with the bottom of them flat upon the ground, like a snail would travel, and as they traveled, they rippled, as if the body of the car were some sort of flowing muscle.
I crouched there watching and now, for the first time, I had a chance to think about it, to try to figure out what was going on. I had come here, across more than sixty million years, to see some dinosaurs, and I sure was seeing them, but under what you might say were peculiar circumstances. The dinosaurs fit, all right. They looked mostly like the way they looked in books, but the dogs and car-men were something else again. They were distinctly out of place.
The dogs were pacing back and forth, sliding along in their sinuous fashion, and the car-men were zipping back and forth, and every once in a while one of the beasts would break out of the circle and the minute that it did, a half dozen dogs and a couple of car-men would race to intercept it and drive it back again.
