Pilgrim at Tinker Creek

  Although mothers devouring their own offspring is patently the more senseless, somehow the reverse behavior is the more appalling. In the death of the parent in the jaws of its offspring I recognize a universal drama that chance occurrence has merely telescoped, so that I can see all the players at once. Gall gnats, for instance, are common small flies. Sometimes, according to Teale, a gall gnat larva, which does not resemble the adult in the least, and which has certainly not mated, nevertheless produces within its body eggs, live eggs, which then hatch within its soft tissues. Sometimes the eggs hatch alive even within the quiescent body of the pupa. The same incredible thing occasionally occurs within the fly genus Miastor, again to both larvae and pupae. “These eggs hatch within their bodies and the ravenous larvae which emerge immediately begin devouring their parents.” In this case, I know what it’s all about, and I wish I didn’t. The parents die, the next generation lives, ad majorem gloriam, and so it goes. If the new generation hastens the death of the old, it scarcely matters; the old has served its one purpose, and the direct processing of proteins is tidily all in the family. But think of the invisible swelling of ripe eggs inside the pupa as wrapped and rigid as a mummified Egyptian queen! The eggs burst, shatter her belly, and emerge a live, awake, and hungry from a mummy case which they crawl over like worms and feed on till its gone. And then they turn to the world.

  “To prevent a like fate,” Teale continues, “some of the ichneumon flies, those wasplike parasites which deposit their eggs in the body tissues of caterpillars, have to scatter their eggs while in flight at times when they are unable to find their prey and the eggs are ready to hatch within their bodies.”

  You are an ichneumon. You mated and your eggs are fertile. If you can’t find a caterpillar on which to lay your eggs, your young will starve. When the eggs hatch, the young will eat any body in which they find themselves, so if you don’t kill them by emitting them broadcast over the landscape, they’ll eat you alive. But if you let them drop over the fields you will probably be dead yourself, of old age, before they even hatch to starve, and the whole show will be over and done, and a wretched one it was. You feel them coming, and coming, and you struggle to rise….

  Not that the ichneumon is making any conscious choice. If she were, her dilemma would be truly the stuff of tragedy; Aeschylus need have looked no further than the ichneumon. That is, it would be the stuff of real tragedy if only Aeschylus and I could convince you that the ichneumon is really and truly as alive as we are, and that what happens to it matters. Will you take it on faith?

  Here is one last story. It shows that the pressures of growth gang aft a-gley. The clothes moth, whose caterpillar eats wool, sometimes goes into a molting frenzy which Teale blandly describes as “curious”: “A curious paradox in molting is the action of a clothes-moth larva with insufficient food. It sometimes goes into a ‘molting frenzy,’ changing its skin repeatedly and getting smaller and smaller with each change.” Smaller and smaller…can you imagine the frenzy? Where shall we send our sweaters? The diminution process could, in imagination, extend to infinity, as the creature frantically shrinks and shrinks and shrinks to the size of a molecule, then an electron, but never can shrink to absolute nothing and end its terrible hunger. I feel like Ezra: “And when I heard this thing, I rent my garment and my mantle, and plucked off the hair of my head and of my beard, and sat down astonied.”

  I am not kidding anyone if I pretend that these awesome pressures to eat and breed are wholly mystifying. The million million barnacle larvae in a half mile of shore water, the rivers of termite eggs, and the light-years of aphids ensure the living presence, in a scarcely concerned world, of ever more rock barnacles, termites, and aphids.

  It’s chancy out there. Dog whelks eat rock barnacles, worms invade their shells, shore ice razes them from the rocks and grinds them to a powder. Can you lay aphid eggs faster than chickadees can eat them? Can you find a caterpillar, can you beat the killing frost?

  As far as lower animals go, if you lead a simple life you probably face a boring death. Some animals, however, lead such complicated lives that not only do the chances for any one animal’s death at any minute multiply greatly, but so also do the varieties of the deaths it might die. The ordained paths of some animals are so rocky they are preposterous. The horsehair worm in the duck pond, for instance, wriggling so serenely near the surface, is the survivor of an impossible series of squeaky escapes. I did a bit of research into the life cycles of these worms, which are shaped exactly like hairs from a horse’s tail, and learned that although scientists are not exactly sure what happens to any one species of them, they think it might go something like this:

  You start with long strands of eggs wrapped around vegetation in the duck pond. The eggs hatch, the larvae emerge, and each seeks an aquatic host, say a dragonfly nymph. The larva bores into the nymph’s body, where it feeds and grows and somehow escapes. Then if it doesn’t get eaten it swims over to the shore where it encysts on submersed plants. This is all fairly improbable, but not impossibly so.

  Now the coincidences begin. First, presumably, the water level of the duck pond has to drop. This exposes the vegetation so that the land host organism can get at it without drowning. Horsehair worms have various land hosts, such as crickets, beetles, and grasshoppers. Let’s say ours can only make it if a grasshopper comes along. Fine. But the grasshopper had best hurry, for there is only so much fat stored in the encysted worm, and it might starve. Well, here comes just the right species of grasshopper, and it is obligingly feeding on shore vegetation. Now I have not observed any extensive grazing of grasshoppers on any grassy shores, but obviously it must occur. Bingo, then, the grasshopper just happens to eat the encysted worm.

  The cyst bursts. The worm emerges in all its hideous length, up to thirty-six inches, inside the body of the grasshopper, on which it feeds. I presume that the worm must eat enough of its host to stay alive, but not so much that the grasshopper will keel over dead far from water. Entomologists have found tiger beetles dead and dying on the water whose insides were almost perfectly empty except for the white coiled bodies of horsehair worms. At any rate, now the worm is almost an adult, ready to reproduce. But first it’s got to get out of this grasshopper.

  Biologists don’t know what happens next. If at the critical stage the grasshopper is hopping in a sunny meadow away from a duck pond or ditch, which is entirely likely, then the story is over. But say it happens to be feeding near the duck pond. The worm perhaps bores its way out of the grasshopper’s body, or perhaps is excreted. At any rate, there it is on the grass, drying out. Now the biologists have to go so far as to invoke a “heavy rain,” falling from heaven at this fortuitous moment, in order to get the horsehair worm back into the water where it can mate and lay more seemingly doomed eggs. You’d be thin, too.

  Other creatures have it just about as easy. A blood fluke starts out as an egg in human feces. If it happens to fall into fresh water it will live only if it happens to encounter a certain species of snail. It changes in the snail, swims out, and now needs to find a human being in the water in order to bore through his skin. It travels around in the man’s blood, settles down in the blood vessels of his intestine, and turns into a sexually mature blood fluke, either male or female. Now it has to find another fluke, of the opposite sex, who also just happens to have traveled the same circuitous route and landed in the same unfortunate man’s intestinal blood vessels. Other flukes lead similarly improbable lives, some passing through as many as four hosts.

  But it is for gooseneck barnacles that I reserve the largest measure of awe. Recently I saw photographs taken by members of the Ra expedition. One showed a glob of tar as big as a softball, jetsam from a larger craft, which Heyerdahl and his crew spotted in the middle of the Atlantic Ocean. The tar had been in the sea for a long time; it was overgrown with gooseneck barnacles. The gooseneck barnacles were entirely incidental, but for me they were the most interesting thing about the whole expe
dition. How many gooseneck barnacle larvae must be dying out there in the middle of vast oceans for every one that finds a glob of tar to fasten to? You’ve seen gooseneck barnacles washed up on the beach; they grow on old ship’s timber, driftwood, strips of rubber—anything that’s been afloat in the sea long enough. They do not resemble rock barnacles in the least, although the two are closely related. They have pinkish shells extending in a flattened oval from a flexible bit of “gooseneck” tissue that secures them to the substratum.

  I have always had a fancy for these creatures, but I’d always assumed that they lived near shores, where chance floating holdfasts are more likely to occur. What are they doing—what are the larvae doing—out there in the middle of the ocean? They drift and perish, or, by some freak accident in a world where anything can happen, they latch and flourish. If I dangled my hand from the deck of the Ra into the sea, could a gooseneck barnacle fasten there? If I gathered a cup of ocean water, would I be holding a score of dying and dead barnacle larvae? Should I throw them a chip? What kind of a world is this, anyway? Why not make fewer barnacle larvae and give them a decent chance? Are we dealing in life, or in death?

  I have to look at the landscape of the blue-green world again. Just think: in all the clean beautiful reaches of the solar system, our planet alone is a blot; our planet alone has death. I have to acknowledge that the sea is a cup of death and the land is a stained altar stone. We the living are survivors huddled on flotsam, living on jetsam. We are escapees. We wake in terror, eat in hunger, sleep with a mouthful of blood.

  Death: W. C. Fields called death “the Fellow in the Bright Nightgown.” He shuffles around the house in all the corners I’ve forgotten, all the halls I dare not call to mind or visit for fear I’ll glimpse the hem of his shabby, dazzling gown disappearing around a turn. This is the monster evolution loves. How could it be?

  The faster death goes, the faster evolution goes. If an aphid lays a million eggs, several might survive. Now, my right hand, in all its human cunning, could not make one aphid in a thousand years. But these aphid eggs—which run less than a dime a dozen, which run absolutely free—can make aphids as effortlessly as the sea makes waves. Wonderful things, wasted. It’s a wretched system. Arthur Stanley Eddington, the British physicist and astronomer who died in 1944, suggested that all of “Nature” could conceivably run on the same deranged scheme. “If indeed she has no greater aim than to provide a home for her greatest experiment, Man, it would be just like her methods to scatter a million stars whereof one might haply achieve her purpose.” I doubt very much that this is the aim, but it seems clear on all fronts that this is the method.

  Say you are the manager of the Southern Railroad. You figure that you need three engines for a stretch of track between Lynchburg and Danville. It’s a mighty steep grade. So at fantastic effort and expense you have your shops make nine thousand engines. Each engine must be fashioned just so, every rivet and bolt secure, every wire twisted and wrapped, every needle on every indicator sensitive and accurate.

  You send all nine thousand of them out on the runs. Although there are engineers at the throttles, no one is manning the switches. The engines crash, collide, derail, jump, jam, burn…. At the end of the massacre you have three engines, which is what the run could support in the first place. There are few enough of them that they can stay out of each others’ paths.

  You go to your board of directors and show them what you’ve done. And what are they going to say? You know what they’re going to say. They’re going to say: It’s a hell of a way to run a railroad.

  Is it a better way to run a universe?

  Evolution loves death more than it loves you or me. This is easy to write, easy to read, and hard to believe. The words are simple, the concept clear—but you don’t believe it, do you? Nor do I. How could I, when we’re both so lovable? Are my values then so diametrically opposed to those that nature preserves? This is the key point.

  Must I then part ways with the only world I know? I had thought to live by the side of the creek in order to shape my life to its free flow. But I seem to have reached a point where I must draw the line. It looks as though the creek is not buoying me up but dragging me down. Look: Cock Robin may die the most gruesome of slow deaths, and nature is no less pleased; the sun comes up, the creek rolls on, the survivors still sing. I cannot feel that way about your death, nor you about mine, nor either of us about the robin’s—or even the barnacles’. We value the individual supremely, and nature values him not a whit. It looks for the moment as though I might have to reject this creek life unless I want to be utterly brutalized. Is human culture with its values my only real home after all? Can it possibly be that I should move my anchor-hold to the side of a library? This direction of thought brings me abruptly to a fork in the road where I stand paralyzed, unwilling to go on, for both ways lead to madness.

  Either this world, my mother, is a monster, or I myself am a freak.

  Consider the former: the world is a monster. Any three-year-old can see how unsatisfactory and clumsy is this whole business of reproducing and dying by the billions. We have not yet encountered any god who is as merciful as a man who flicks a beetle over on its feet. There is not a people in the world who behaves as badly as praying mantises. But wait, you say, there is no right and wrong in nature; right and wrong is a human concept. Precisely: we are moral creatures, then, in an amoral world. The universe that suckled us is a monster that does not care if we live or die—does not care if it itself grinds to a halt. It is fixed and blind, a robot programmed to kill. We are free and seeing; we can only try to outwit it at every turn to save our skins.

  This view requires that a monstrous world running on chance and death, careening blindly from nowhere to nowhere, somehow produced wonderful us. I came from the world, I crawled out of a sea of amino acids, and now I must whirl around and shake my fist at that sea and cry Shame! If I value anything at all, then I must blindfold my eyes when I near the Swiss Alps. We must as a culture disassemble our telescopes and settle down to backslapping. We little blobs of soft tissue crawling around on this one planet’s skin are right, and the whole universe is wrong.

  Or consider the alternative.

  Julian of Norwich, the great English anchorite and theologian, cited, in the manner of the prophets, these words from God: “See, I am God: see, I am in all things: see, I never lift my hands off my works, nor ever shall, without end…. How should anything be amiss?” But now not even the simplest and best of us sees things the way Julian did. It seems to us that plenty is amiss. So much is amiss that I must consider the second fork in the road, that creation itself is blamelessly, benevolently askew by its very free nature, and that it is only human feeling that is freakishly amiss. The frog that the giant water bug sucked had, presumably, a rush of pure feeling for about a second, before its brain turned to broth. I, however, have been sapped by various strong feelings about the incident almost daily for several years.

  Do the barnacle larvae care? Does the lacewing who eats her eggs care? If they do not care, then why am I making all this fuss? If I am a freak, then why don’t I hush?

  Our excessive emotions are so patently painful and harmful to us as a species that I can hardly believe that they evolved. Other creatures manage to have effective matings and even stable societies without great emotions, and they have a bonus in that they need not ever mourn. (But some higher animals have emotions that we think are similar to ours: dogs, elephants, otters, and the sea mammals mourn their dead. Why do that to an otter? What creator could be so cruel, not to kill otters, but to let them care?) It would seem that emotions are the curse, not death—emotions that appear to have devolved upon a few freaks as a special curse from Malevolence.

  All right then. It is our emotions that are amiss. We are freaks, the world is fine, and let us all go have lobotomies to restore us to a natural state. We can leave the library then, go back to the creek lobotomized, and live on its banks as untroubled as any muskrat or reed.
You first.

  Of the two ridiculous alternatives, I rather favor the second. Although it is true that we are moral creatures in an amoral world, the world’s amorality does not make it a monster. Rather, I am the freak. Perhaps I don’t need a lobotomy, but I could use some calming down, and the creek is just the place for it. I must go down to the creek again. It is where I belong, although as I become closer to it, my fellows appear more and more freakish, and my home in the library more and more limited. Imperceptibly at first, and now consciously, I shy away from the arts, from the human emotional stew. I read what the men with telescopes and microscopes have to say about the landscape. I read about the polar ice, and I drive myself deeper and deeper into exile from my own kind. But, since I cannot avoid the library altogether—the human culture that taught me to speak in its tongue—I bring human values to the creek, and so save myself from being brutalized.

  What I have been after all along is not an explanation but a picture. This is the way the world is, altar and cup, lit by the fire from a star that has only begun to die. My rage and shock at the pain and death of individuals of my kind is the old, old mystery, as old as man, but forever fresh, and completely unanswerable. My reservations about the fecundity and waste of life among other creatures is, however, mere squeamishness. After all, I’m the one having the nightmares. It is true that many of the creatures live and die abominably, but I am not called upon to pass judgment. Nor am I called upon to live in that same way, and those creatures who are are mercifully unconscious.

  I don’t want to cut this too short. Let me pull the camera back and look at that fork in the road from a distance, in the larger context of the speckled and twining world. It could be that the fork will disappear, or that I will see it to be but one of many interstices in a network, so that it is impossible to say which line is the main part and which is the fork.
