The morning was fast declining, and although we had, as I said, Ruhmkorff lamps, and had brought along food in our bags, and so could have passed a comfortable enough night there on the plain, St. Ives was in a hurry to finish his research and be off. The lamps were an emergency precaution, he said. If all went according to plan, we’d while away the afternoon and launch at dusk. We mustn’t be seen, he reminded us again. We had accomplished a third of our mission by having arrived at all — the half-completed painting was proof enough that we’d effectively disposed of several hundred centuries. We would accomplish another third when we found ourselves safe at home at last, or at least once again in our own century, where we could spend the night on the plain if we chose to. The final third was simple enough, it seemed to me: we’d observe, is what we’d do. A “field study” St. Ives called it, although it seemed to him to be the most ticklish business of the lot. We would lounge about, keeping ourselves hidden behind a tumble of rock a hundred meters above the cave, and every now and again we’d pop up and snap a photograph of a wandering bison or cave bear, and haul the evidence back to London, where the Royal Academy would be toppled onto their collective ear.
I hefted my bag and slung a tripod over my shoulder and made as if to set out. St. Ives nearly throttled himself stopping me. “Your footprints” he said, pointing to the soft silt of the cave floor. And there, sure enough, were the prints of a pair of boots bought in Bond Street, London, either three weeks or thirty-five centuries earlier, I couldn’t have said for certain at the time. St. Ives yanked a feather duster out of his bag and went to work on the prints. He was a man possessed. There mustn’t be a trace, he said, of our coming and going. It took us the better part of an hour, sneaking and skulking and breaking our backs with the hurry of it, to transport the machine, which, thank heaven, was remarkably light and could be partially dismantled, up to our aerie in the rocks. Then we were at it for another hour in the gloom of evening, dusting away tracks, replacing pebbles kicked aside in haste, grafting the snapped limb of a scrub plant back onto itself — taking frightful care, in other words, that no sentient being could remark our passing, and all the time Hasbro keeping watch above, whistling us into hiding at the approach of so much as a rodent.
We daren’t, said St. Ives, meddle with anything. The slightest alteration in the natural state of the landscape might have ungovernable consequences in ages to come. The universe, it seems, is but a tenuous, delicate composition, rather like the reflected jumble of tinted jewels in a kaleidoscope. If one holds still while gazing into the end of the thing, the jewels sit there perfectly at ease, as if the reflected pattern isn’t a clever ruse after all, but is a church window fixed into a wall of cut stone. But the slightest jiggling — the blink of an eye or the tremor of a sudden chill — casts the jewels into disarray, and no earthly amount of twisting and shaking and wishing will fetch them back again in the lost order. And so goes the universe.
What if a bug, said St. Ives, were crushed inadvertently underfoot, and that bug weren’t as a result, eaten, say, by the toad which, historically, would have eaten that bug had the bug not been crushed by a bootheel that had no business being there in the first place. That toad might die — mightn’t he? — for lack of a bug to eat, or from having eaten another bug out of desperation that he hadn’t ought to have eaten. And the wild dog that would have eaten the toad, he’d go hungry, you see, and attempt the conquest of a toad which the universe had earmarked for an utterly different dog, who, everything being built upon everything else, like the crystals, as I said, in a kaleidoscope, would have to turn out and eat a rabbit. And that rabbit, which otherwise would have lived into a satisfying old age and bore six dozen rabbits very much like it, would be dead — wouldn’t it? — and no end of prehistoric beasts would be denied the pleasure of dining on those six dozen rabbits.
You see how it goes. When St. Ives laid it out for me I was transfixed. I could tell straightaway that our puny comings and goings through the veil of time were as nothing in the eyes of the universe, compared to the brief few hours we intended to spend among the stones of the hillside. A bug and a toad and six dozen rabbits and pretty soon the entire local crowd is in an uproar. The universe they thought they could depend on has gone to smash. A megatherium looks for roots to nibble one morning and the roots are gone, because a half score wild dogs have moved to the coast where the rabbit population is more dependable, and the rabbits, finding travel a safer thing than it was last week, reproduce tenfold and make up, as they say, for lost time. Their offspring eat the roots that the megatherium thought he could count on and so he eats someone else’s roots and so on and so on, magnified over countless centuries.
The crowning result is that the people of London aren’t the people of London anymore at all. The Romans never arrived, for reasons that can be traced, if one had the right instruments, to the crushed bug. The Greeks, say, got in before them, and lived in the countryside in huts, spinning philosophies, and made peace with their Celtic neighbors and the middle ages crept past without so much as a mention of feudal states. I can tell you that it boggled my mind, to use the popular phrase, when St. Ives told me about it. That crushed bug, depend on it, would send the jewels tumbling, and where they’d fall, no one on Earth could puzzle out, try as he might and given a notebook and pen to calculate with.

We were dusty and hot before we were done that evening. A mammoth had come past, as if looking for something he’d lost, and St. Ives snapped a dozen photographs of the beast before it ambled away. Then a rhinoceros of some vintage appeared, and out came the camera again. I was a frightful mass of dirt and stinging insects and, indelicate as it sounds, perspiration, and was surprised to find a pool of clear water in the rocks, the product of a slowly running spring. I spent a cool half hour scrubbing up, and was happy enough to have brought along the requisite toiletries.
One is tempted — or at least I am — to dispense with the niceties when traveling rough. What purpose is there in trimming one’s mustache, you ask, when one is tenting in the Hebrides? We can take a lesson from Robinson Crusoe, who maintained a degree of gentility even when lost forever, he supposed, on a desert island. Which one of us wouldn’t have run naked with the savages before the month was gone? Not Crusoe. And so with me. I tread on the temptation to run with the savages, and although in truth I neglected to bring a mustache scissors (we were to be away, at most, for half a day) I carried with me a comb and brush and a bottle of rose oil, and, as I say, I wielded those tools to good effect while St. Ives, caught up in the fever of his picture-taking, let me go about my business.
And I was careful. There were tiny fish, in fact, down in that shallow pool, fish that had no need for a dose of rose oil. I skimmed three broken hairs from the placid surface — which surface I had used as a mirror — and I put the hairs in my pocket and carried them back with me.
I had finished up and felt entirely restored when the sun, with a rapidity which never fails to amaze me, sank beyond the primeval horizon. Night descended like a lead curtain, and almost at once there sounded roundabout us such a shrieking and mewling and growling as I hope never to hear again. The night was alive with prowling beasts, and us with neither shelter nor fire. We were at it again, hustling the machine back into the cave. Our cave painter hadn’t yet returned. With a cloth thrown over a lamp, once again we scoured out our footprints, watching with wary nervousness the pairs of eyes that shined at us out of the darkness. We launched an hour after sunset, and I heartily believed, along with St. Ives and Hasbro, that we left behind us not a trace of our having been there — nothing which might in the least joggle the delicate mechanism of the temporal and spacial universe.
