"And you used to give me a sack of candy."

His eyes twinkled beneath the heavy brows and he gave my hand an extra hearty shake, then dropped it.

It was going to be all right, I told myself. The old Pilot k.n.o.b still existed and I was no stranger. I was coming home.

"And you're the same one," he said, "as is on the radio and sometimes on television."

I admitted that I was.

"Pilot k.n.o.b," he told me, "is plumb proud of you. It took some getting used to at first to listen to a home-town boy on the radio or sit face to face with him on the television screen. But we got used to it at last and most of us listened to you and talked about it afterwards. We'd go around saying to one another that Horton has said this or that and we took what you had to say for gospel. But," he asked, "what are you doing back? Not that we aren't glad to have you."

"I think I'll stay for a while," I told him. "For a few months, maybe for a year."

"Vacation?"

"No. Not a vacation. There's some writing that I want to do. And to do that writing I had to get away somewhere. Where I would have time for writing and a bit of time for thinking what to write."

"A book?"

"Yes, I hope a book."

"Well, seems to me," he said, rubbing the back of his neck with his hand, "you might have a lot to put into a hook. Maybe a lot of things you couldn't say right out on the air. All them foreign places you was in. You were in a lot of them."

"A few of them," I said.

"And Russia? What did you think of Russia?"

"I liked the Russian people. They seemed, in many ways, like us."

"You mean like Americans?"

"Like Americans," I said.

"Well, come over to the stove," he said, "and let us sit and talk. I ain't got a fire in it today. I guess one isn't needed. I can remember, plain as day, your pa sitting in one of these chairs and talking with the others. He was a right good man, your pa, but I always said he wasn't cut out to be a farmer."

We sat down in two of the chairs.

"Is your pa still alive?" he asked.

"Yes, he and Mother both. Out in California. Retired now and very comfortable."

"You got a place to stay?"

I shook my head.

"New motel down by the river," Duncan said. "Built just a year or two ago. New people, by the name of Streeter. Give you good rates if you're staying more than a day or two. I'll make sure they do it. I'll speak to them about it."

"There's no need .. ."

"But you ain't no transient. You're home folk, come back again. They would want to know."

"Any fishing?"

"Best place on the river. Got some boats to rent and a canoe or two, although why anyone would risk their neck in a canoe on that river is more than I can figure."

"I was hoping for a place like that," I said. "I was afraid there would be none."

"Still crazy about fishing?"

"I enjoy it," I said.

"Remember when you were a boy you were rough on chubs."

"Chubs made good fun," I said.

"There're still a lot of people you will remember," said Duncan. "They'll all want to see you. Why don't you drop in on the school program tonight? A lot of people will be there. That was the teacher that was hi here, name of Kathy Adams."

"You still have the old one-room school?"

"You can bet we have," he said. "There was pressure put on us and some of the other districts to consolidate, but when it was put up to a vote we beat it. Kids get just as good an education in a one-room school as they would get in a new and fancy building and it costs a whole lot less. Kids that want to go to high school, we pay their tuition, but there aren't many of them that want to go. Still costs less than if we were consolidated. No use spending money for a high school when you got a bunch of kids like them Williams brats . . ."

"I am sorry," I said, "but when I stepped inside I couldn't help but hear ..."

"Let me tell you, Horton, that Kathy Adams is a splendid teacher, but she is too soft-hearted. She is always standing up for them Williams kids and I tell you they are nothing but a gang of cutthroats. I guess you don't know Tom Williams; he came floating in here after you had left. He worked around on some of the farms, but he was mostly good-for-nothing, although he must have managed to save a little money. He was well past marrying age when he got hitched up with one of Little Poison Carter's daughters. Amelia was her name. You remember Little Poison, don't you?" I shook my head.

"Had a brother that was called Big Poison. No one now recollects their rightful names. The whole tribe lived down on Muskrat Island. Well, anyhow, when Tom married Amelia he bought, with the money he had saved, this little shirttail piece of land a couple of miles up Lonesome Hollow and tried to make a farm of it. He's got along somehow; I wouldn't know exactly how. And every year or so there was a kid and him and Mrs. Tom let those kids run wild. I tell you, Horton, these are the kind of folks we can get along without. They cause no end of trouble-Old Tom Williams and that family that he's raising. They keep more dogs than you can shake a stick at and those dogs are worthless, just like Old Tom himself. They lay around all day and they eat their heads off and they ain't worth a lick. Tom says he just likes dogs. Have you ever heard a thing like that? A trifling kind of fellow, with his dogs and kids and the kids are always in some kind of trouble."

"Miss Adams seemed to think," I reminded him, "that it's not their fault entirely."

"I know. She says they felt rejected and are underprivileged. That's another favorite word of hers. You know what underprivileged means? It means someone who has no get-up-and-go. There wouldn't need to be no underprivileged if everyone was willing to Work and had a lick of common sense. Oh, I know what the government says about them and how we got to help them. But if the government just would come out here and have a look at some of these underprivileged folks, they'd see in a minute what was wrong with them."

"I was wondering," I said, "as I drove along this morning, if there still are rattlesnakes."

"Rattlesnakes?" he asked. '

"There used to be a lot of them when I was a kid. I was wondering if they might be getting thinned out some."

He wagged his head sagaciously. "Maybe some. Although there's still a bait of them. Get back in the hills and you'll find plenty of them. You interested in them?"

"Not especially," I said.

"You'll have to come to that school program tonight," he said. "There'll be a lot of people there. Some of them you'll know. Last day of school and the kids will all perform-get up and say some pieces or maybe sing a song or put on little plays. And afterwards there'll be a basket social to raise money for new library books. We still hang on to the old ways here; the years haven't changed us much. And we manage to have our own good times. A basket social at the school tonight and a couple of weeks from now there'll be a strawberry festival down at the Methodist church. Both of them good places to meet old friends of yours."

"I'll make it if I can," I promised. "Both the program and the festival."

"You've got some mail," he told me. "It has been piling up for a week or two. I still am postmaster here. The post office has been right here in this store for almost a hundred years. But there's talk of taking it away from us, consolidating it with the office over at Lancaster and sending it out from there by rural route. Government isn't satisfied leaving things alone. They got to always be trying to make things over. Improving service, they call it. I 'can't see, for the life of me, what's wrong with the kind of service we been giving the folks of Pilot k.n.o.b for the last hundred years or so."

"I had expected you might have a bundle of mail for me," I said. "I had it forwarded, but I didn't hurry to get here. I took my time and stopped at several places I wanted to look over."

"You'll be going out to have a look at the old farm, the place you used to live?"

"I don't think I will," I said. "I'd see too many changes."

"Family by the name of Ballard lives there now," he said. "They have a couple of boys, grown men almost. Do a lot of drinking, those two boys, and sometimes are a problem."

I nodded. "You say this motel is down by the river?" "That's right. You drive down past the schoolhouse and the church to where the road bends to the left. A little ways beyond you will see the sign. Says River Edge Motel.

I'll get your mail for you."

The large manila envelope had Philip Freeman's return address written in a scrawling hand across its upper left-hand corner. I sat in the chair by the open window, turning it slowly in my hand, wondering why Philip should be writing or sending anything to me. I knew the man, of course, and liked him, but we never had been close. The only link between us was our mutual affection and respect for the grand old man who had died some weeks before in an auto accident.

Through the window came the talking of the river, the muttered conversation it held with the countryside as it went sliding through the land. The sound of its talk, as I sat there listening, brought back in memory the times when my father and I had sat on its bank and fished-always with my father, but never by myself. For the river potentially was too dangerous for a boy of ten. The creek, of course, was all right if I promised to be careful.

The creek had been a friend, a shining summer friend, but the river had been magic. And it was magic still, I thought, a magic compounded of boyhood dreams and time. And finally here I was again beside it; here I would live beside it for a time and now I realized that I was afraid, deep inside myself, that living close beside it I would get to know it so well that the magic would be lost and it would become just another river running down another land.

Here were quiet and peace, I thought-the kind of quiet and peace that could be found in only a few other backwater corners of the earth. Here a man might find the time and s.p.a.ce to think, undisturbed by the intrusion of the static that was given off by the rumblings of world commerce and.- global politics. Here was a country that the rush of progress had swept past, barely touching it.

Barely touching it, and thus leaving it with some of its old ideas. This place did not know that G.o.d was dead; in the little church at the upper end of the village the minister still might preach of fire and brimstone and his congregation would give him rapt attention. This place felt no overwhelming social guilt; it still believed that it was meet and proper that a man should work to earn a living. This place did not subscribe to deficit spending; it tried to get along with what it had and thus hold down the taxes. Once good and sterling virtues, but no longer so if measured against modern att.i.tudes. And yet, I thought, not buried in the trivia of the outside world-escaping not only the physical trivia, but the intellectual and the moral and the aesthetic trivia as well. Still able to believe, in a world that had stopped believing. Still holding fast to certain values, even if mistaken values, in a world that had few values left. Still fiercely concerned about the fundamentals of life and living while much of the world long since had escaped into cynicism.

I glanced about the room, a simple place-small and bright and clean, with a minimum of furniture, with paneling on the wall and no carpet on the floor. A monk's cell, I thought, and that was the way it should be, for a man could do little work smothered in an overburden of conveniences.

Peace and quiet, I thought, and what about the rattlesnakes? Could this peace and quiet be no more than a tricky surface, the millpond water that masked a whirlpool's violence? I saw it all again-the cruel, skull-like head hanging over me-and as I remembered it my body ached with a recall of the tension that had frozen it into immobility.

Why should anyone have planned and executed such a bizarre attempt at murder? Who had done it and how had it been carried out and why should it be me? Why had there been two farmhouses so alike that one could scarcely be differentiated from the other? And what about Snuffy Smith and the stuck car that wasn't really stuck and the Triceratops that after a little time wasn't there at all?

I gave up. There were no answers. The only possible answer seemed to be that it had never happened and I was sure- k had. A man could imagine any one of all these things, perhaps; he could not, certainly, imagine all of them. There must, I knew, be an explanation somewhere, but I didn't have it.

I laid the manila envelope aside and looked at the other mail and there was little of importance. There were several notes from friends wishing me well in my new place of residence, but most of the notes had a trace of false joviality about them I was not sure I liked. Everyone, it seemed, thought that I was slightly crazy to bury myself in what to them was wilderness to write what probably would turn out to be a very lousy book. There were a couple of bills I had forgotten to pay and there were a magazine or two and some advertising.

I picked up the manila envelope again and ripped it open. Out of it came a sheaf of Xeroxed pages with a handwritten note clipped to them.

The note said: Dear Horton: When I went through the papers in Uncle's desk, I ran across the enclosed and, knowing you were one of his closest and most valued friends, I ran off a copy for you. Frankly, I don't know what to make of it. With some other man I might think it was nothing more than a fantasy that, for some whimsical, personal reason, he had written down-perhaps to clear it from his mind. But Uncle was not whimsical, as I think you will agree. I am wondering if he might at some time have mentioned this to you. If such should be the case, you may have a better understanding of it than I seem able to muster-Philip.

I pulled the note clear from the stapled Xeroxed sheets and there, in the crabbed, miserly handwriting of my friend (a handwriting so unlike the man himself), was the doc.u.ment.

There was no heading on the sheet. Nothing to tell what he had intended it to be.

I settled down into the chair and began to read.

The evolutionary process (the doc.u.ment began) is a phenomenon which has been of special and absorbing interest to me all my life, although in my own particular field I have been concerned only with one small, and perhaps unspectacular, aspect of it. As a professor of history, I have been more and more intrigued, as the years go on, with the evolutionary trend of human thought. I would be ashamed to enumerate how many times I've tried and how many hours I've spent in attempting to draw up a graph or chart or diagram, or whatever one might call it, to show the change and development in human thought through all historic ages. The subject, however, is too vast and too diverse (and in some instances, I might as well confess, too contradictory) to lend itself to any ill.u.s.trative scheme I've been able to devise. And yet I am sure that human thought has been evolutionary, that the basis of it has shifted steadily through all of man's recorded time, that we do not think as we did a hundred years ago, that our opinions are much changed from a thousand years ago, not so much attributable to the fact that we now have better knowledge upon which to base our thinking, but that the human viewpoint has undergone a change-an evolution, if you please.

It may seem amusing that anyone should become so absorbed in the process of human thought. But those who "think it amusing would be wrong. For it is the capability of abstract thought and nothing else which distinguishes the human being from any other creature that lives upon the earth.

Let us take a look at evolution, without attempting, or pretending to delve deeply into it, only touching a few of those more obvious landmarks which we are told by paleontologists highlight the path of progress from that primal ocean in which the first microscopic forms of life came into being at a very distant time. Not hunting for, or concerning ourselves with all the subtle changes which marked development, but only noting some of the horizon lines which stand out as a result of all those subtle changes.

One of those first great landmarks must necessarily be" the emergence of certain life forms from the water to live upon the land. This ability to change environment undoubtedly was a much protracted and perhaps a painful and probably a hazardous procedure. But to us today time telescopes it into a single event which stands out as a high point hi the evolutionary scheme. Another high point was the development of the notochord which, in millions of years to come, evolved into a backbone. Yet another high point was the development of bipedal locomotion, although I, personally, am inclined to discount somewhat the significance of the erect position. If one talks of man, it was not the ability to walk erect, but the ability to think beyond the moment and in other terms than the here and now that made him what he is today.

The evolutionary process represents a long chain of events. Many evolutionary trends ran their courses and were discarded and many species became extinct because they were tied inexorably into some of those evolutionary trends. But it was always from some factor, or perhaps from many factors which were involved in the development of those extinct life forms, that new evolutionary lines arose. And the thought must occur to one that through all this tangled jungle of change and modification there must have run a single central core of evolution pointing toward some final form. Through all the millions of years, that central evolutionary form, now expressed in man, lay in the slow growth of a brain which in time became a mind.

One thing, it seems to me, that stands out in the evolutionary process is that while developments, once they've happened, do make uncommon sense, no observer before the fact could have made a valid prediction that they were about to happen. It would not have made good sense for an observer, a half billion years ago, to have predicted that in a few more million years life forms would leave the water and live upon the land. It would have seemed, as a matter of fact, a most unlikely thing, well-nigh impossible. For life forms as they were then constructed, needed the water; they could live nowhere else but in the water. And the land of that day, sterile and barren, must have seemed as incredibly hostile to life as s.p.a.ce seems to us today.

Life forms, half a billion years ago, were small. Smallness then must have seemed as much a part of life as water. No observer in that day could possibly have imagined the monster dinosaurs of later ages, or the modern whale. Such size the observer would have thought to be impossible. Flying he would not have thought of at all; it would have been a concept which would not have crossed his mind. And even if, by some remote chance, it had, he would have seen no way for it to happen, or no reason for it.

So while we can look back, after the fact, and sense the validity and the rightness of all evolutionary progress, there seems no way in which it can be predicted.

The question of what may come after man is a thought which has arisen at times, although largely as a matter of idle speculation. There is a reluctance, I would imagine, for anyone to think too seriously of it. Most people would believe, if they thought of it at all, that it is a question which lies so far in the future that it is senseless for one to give it consideration. The primates have been around only eighty million years or so, perhaps somewhat less than that; man for only two or three million, even at the most optimistic calculation. So, measured against the trilobites and dinosaurs, the primates have many millions of years still left before they become extinct or before they lose their position of dominance upon the earth.

Also there may be a reluctance to admit, even by the thinking of it, that man ever will become extinct. Some men (by no means all of them) can reconcile themselves to the realization that they, personally, some day will die. A man can imagine the world with himself no longer in it; it is far more difficult to imagine an earth with no humans left. We shy away, with some strange inner fear, from the death of the species. We know, intellectually, if not emotionally, that some day we, as members of the human race, will cease to exist; it is difficult to think, however, that the human race itself is not immortal and eternal. We can say that man is the only species which has developed the means by which he can bring about his own extinction. But while we may say this, we do not, in our hearts, believe it.

What little serious speculation there has been about this subject has not really been about it at all. There seems to be a mental block which prevents consideration of it. We almost never speculate upon what might supersede man; what we do is to conjure up a future superman-inhuman in many ways, perhaps, but still a man. Alienated from us in a mental and intellectual sense, but still, biologically, a man. Even here, in this kind of speculation, we perpetuate the stubborn belief that man will go on forever and forever.

This, of course, is wrong. Unless the evolutionary process, in bringing forth the human race, has reached a dead end, there will be something more than man. History would seem to say that the evolutionary process has not reached a dead end. Through the ages there has been evidence that the principle of evolution is never at a loss to produce new life forms or to introduce new survival values. There is no reason to believe, on present evidence, that in man the evolutionary process has used up all its bag of tricks.

So there will be something after man, something other than man. Not just an extension or modification of man, but something entirely different. We ask, in horror and disbelief, what could supersede man, what could beat intelligence?

I believe I know.

I believe the superseder is already in existence and has been for many years.

Abstract thought is a new thing in the world. No other creature than man ever has been blessed (or cursed) with such a faculty. It took from us the old security accorded other creatures which are aware of nothing except the here and now, and in some cases aware only dimly of the here and now. It let us look into the past and, what is worse, peer darkly futureward. It made us aware of loneliness, and filled us with a hope, from which stemmed hopelessness, and it showed us how we stood alone, naked and defenseless, before the uncaring of the cosmos. That day when the first manlike creature became aware of the implications of s.p.a.ce and time as related to himself must be cla.s.sed, at once, as the most fearful and most glorious day in the history of life upon the earth.

We used our intelligence for many practical purposes and for theoretical probing which, in turn, gave us other answers for practical application. And we used it for something else as well. We used it to fill an enigmatic world with many shadowy creatures-with G.o.ds, devils, angels, ghosts, nymphs, fairies, brownies, goblins. We created in our tribal minds a dark and warring world in which we had enemies and allies. And we created other mythical creatures which were neither dark nor fearsome, but simply pleasant products of our imagination-Santa Claus, the Easter Rabbit, Jack Frost, the Sandman, and many, many others. Not only did we create these things intellectually, but we believed in them in varying degrees. We saw them and we talked of them and they were very real to us. Why, if not for fear of meeting such things, did the peasants of medieval days in Europe bar their hovels at the fall of night and refuse to venture out? Why the fear of the dark still inherent in many modern men if it is not the fear of meeting something in the dark? Today we talk but little of these things of the dark, but that the old uneasiness and fear may still be with us is demonstrated by the wide belief today in such things as flying saucers. In this enlightened day it may be childish to talk of werewolf or of ghoul, but it is all right to believe in a technical wraith such as a flying saucer.

What do we know of abstract thought? The answer, of course, is that we know nothing of it. There is a possibility, I understand, that it may be electrical in nature and that it is based upon some sort of energy exchange, for the physicists tell us that all processes must be based on energy. But what do we know, actually, either of electricity or of energy? What do we know, when one comes down to it, about anything at all? Do we know how the atom works or why it works or what an atom is? Can anyone explain the awareness of self and environment which distinguishes life from inorganic matter?

We think of thought as a mental process and we do lip service to the physicists by admitting that an energy exchange must somehow be involved. But we know no more about the thought processes, perhaps even less, than the ancient Greeks knew about the atom. Democritus, who lived during the fourth century before Christ, is generally accorded the honor of being the first man to put forward the atomic theory, and this was, admittedly, an advance in thinking, but the atoms of Democritus were a far cry, indeed, from what we now think of as atoms-and, which, incidentally, we still do not understand. So we talk of thought today as the Greeks in the day of Democritus may have talked (although only briefly and without too much conviction or belief) about the atom, and with as little understanding. We are, when it comes down to the truth of it, only mouthing words.

We do know something of the result of thought. All that mankind has today is the product of his thinking. But this is the result of the impact of the thought upon the human animal, as steam makes an impact upon a mechanism and makes an engine run.

We might ask, once the steam has made its impact and performed its function, what happens to the steam? 1 think that it is as logical to ask, once thought has made its impact, what happens to the thought-to that exchange of energy which we are told is necessary to bring about and produce the thought.

I think 1 know the answer. I believe that thought, the energy of thought, whatever strange form thought itself might take, streaming unceasingly through the centuries from the minds of billions of men and women, has given rise to a group of beings which in time, perhaps a not too distant time, will supersede the human race.
