Over Prairie Trails (4 page)

P
eter took me north, alone, on six successive trips. We had rain, we had snow, we had mud, and hard-frozen ground. It took us four, it took us six, it took us on one occasion – after a heavy October snowfall – nearly eleven hours to make the trip. That last adventure decided me. It was unavoidable that I should buy a second horse. The roads were getting too heavy for single driving over such a distance. This time I wanted a horse that I could sell in the spring to a farmer for any kind of work on the land. I looked around for a while. Then I found Dan. He was a sorrel, with some Clyde blood in him. He looked a veritable skate of a horse. You could lay your fingers between his ribs, and he played out on the first trip I ever made with this newly-assembled, strange-looking team. But when I look back at that winter, I cannot but say that again I chose well. After I had fed him up, he did the work in a thoroughly satisfactory manner, and he learnt to know the road far better than Peter. Several times I should have been lost without his unerring road sense. In the spring I sold him for exactly what I had
paid; the farmer who bought him has him to this very day
^*
and says he never had a better horse.

I also had found that on moonless nights it was indispensable for me to have lights along. Now maybe the reader has already noticed that I am rather a thorough-going person. For a week I worked every day after four at my buggy and finally had a blacksmith put on the finishing touches. What I rigged up, was as follows: on the frontsprings I fastened with clamps two upright iron supports; between them with thumbscrews the searchlight of a wrecked steam tractor which I got for a “Thank-you” from a junk-pile. Into the buggy box I laid a borrowed acetylene gas tank, strapped down with two bands of galvanized tin. I made the connection by a stout rubber tube, “guaranteed not to harden in the severest weather.” To the side of the box I attached a short piece of bandiron, bent at an angle, so that a bicycle lamp could be slipped over it. Against the case that I should need a handlight, I carried besides a so-called dashboard coal-oil lantern with me. With all lamps going, it must have been a strange outfit to look at from a distance in the dark.

I travelled by this time in fur coat and cap, and I carried a robe for myself and blankets for the horses, for I now fed them on the road soon after crossing the creek.

Now on the second Friday of November there had been a smell of smoke in the air from the early morning. The marsh up north was afire – as it had been off and on for a matter of twenty-odd years. The fire consumes on the surface everything that will burn; the ground cools down, a new vegetation springs up, and nobody would suspect – as there is nothing to indicate – that only a few feet below the heat lingers, ready to
leap up again if given the opportunity. In this case I was told that a man had started to dig a well on a newly filed claim, and that suddenly he found himself wrapped about in smoke and flames. I cannot vouch for the truth of this, but I can vouch for the fact that the smoke of the fire was smelt for forty miles north and that in the afternoon a combination of this smoke (probably furnishing “condensation nuclei”) and of the moisture in the air, somewhere along or above the lake brought about the densest fog I had ever seen on the prairies. How it spread, I shall discuss later on. To give an idea of its density I will mention right here that on the well travelled road between two important towns a man abandoned his car during the early part of the night because he lost his nerve when his lights could no longer penetrate the fog sufficiently to reach the road.

I was warned at noon. “You surely do not intend to go out to-night?” remarked a lawyer-acquaintance to me at the dinner table in the hotel; for by telephone from lake-points reports of the fog had already reached the town. “I intend to leave word at the stable right now,” I replied, “to have team and buggy in front of the school at four o’clock.” “Well,” said the lawyer in getting up, “I would not; you’ll run into fog.”

And into fog I did run. At this time of the year I had at best only a little over an hour’s start in my race against darkness. I always drove my horses hard now while daylight lasted; I demanded from them their very best strength at the start. Then, till we reached the last clear road over the dam, I spared them as much as I could. I had met up with a few things in the dark by now, and I had learned, if a difficulty arose, how much easier it is to cope with it even in failing twilight than by the gleam of lantern or headlight; for the latter never illumine more than a limited spot.

So I had turned Bell’s corner by the time I hit the fog. I saw it in front and to the right. It drew a slanting line across the road. There it stood like a wall. Not a breath seemed to be stirring. The fog, from a distance, appeared to rise like a cliff, quite smoothly, and it blotted out the world beyond. When I approached it, I saw that its face was not so smooth as it had appeared from half a mile back; nor was it motionless. In fact, it was rolling south and west like a wave of great viscosity. Though my senses failed to perceive the slightest breath of a breeze, the fog was brewing and whirling, and huge spheres seemed to be forming in it, and to roll forward, slowly, and sometimes to recede, as if they had encountered an obstacle and rebounded clumsily. I had seen a tidal wave, fifty or more feet high, sweep up the “bore” of a river at the head of the Bay of Fundy. I was reminded of the sight; but here everything seemed to proceed in a strangely, weirdly leisurely way. There was none of that rush, of that hurry about this fog that characterizes water. Besides there seemed to be no end to the wave above; it reached up as far as your eye could see – now bulging in, now out, but always advancing. It was not so slow, however, as for the moment I judged it to be; for I was later on told that it reached the town at about six o’clock. And here I was, at five, six and a half miles from its limits as the crow flies.

I had hardly time to take in the details that I have described before I was enveloped in the folds of the fog. I mean this quite literally, for I am firmly convinced that an onlooker from behind would have seen the grey masses fold in like a sheet when I drove against them. It must have looked as if a driver were driving against a canvas moving in a slight breeze – canvas light and loose enough to be held in place by the resistance of the air so as to enclose him. Or maybe I
should say “veiling” instead of canvas – or something still lighter and airier. Have you ever seen milk poured carefully down the side of a glass vessel filled with water? Well, clear air and fog seemed to behave towards each other pretty much the same way as milk in that case behaves towards water.

I am rather emphatic about this because I have made a study of just such mists on a very much smaller scale. In that northern country where my wife taught her school and where I was to live for nearly two years as a convalescent, the hollows of the ground on clear cold summer nights, when the mercury dipped down close to the freezing point, would sometimes fill with a white mist of extraordinary density. Occasionally this mist would go on forming in higher and higher layers by condensation; mostly, however, it seemed rather to come from below. But always, when it was really dense, there was a definite plane of demarcation. In fact, that was the criterion by which I recognised this peculiar mist. Mostly there is, even in the north, a layer of lesser density over the pools, gradually shading off into the clear air above. Nothing of what I am going to describe can be observed in that case.

One summer, when I was living not over two miles from the lakeshore, I used to go down to these pools whenever they formed in the right way; and when I approached them slowly and carefully, I could dip my hand into the mist as into water, and I could feel the coolness of the misty layers. It was not because my hand got moist, for it did not. No evaporation was going on there, nor any condensation either. Nor did noticeable bubbles form because there was no motion in the mass which might have caused the infinitesimal droplets to collide and to coalesce into something perceivable to my senses.

Once, of a full-moon night, I spent an hour getting into a pool like that, and when I looked down at my feet, I could
not see them. But after I had been standing in it for a while, ten minutes maybe, a clear space had formed around my body, and I could see the ground. The heat of my body helped the air to redissolve the mist into steam. And as I watched, I noticed that a current was set up. The mist was continually flowing in towards my feet and legs where the body-heat was least. And where evaporation proceeded fastest, that is at the height of my waist, little wisps of mist would detach themselves from the side of the funnel of clear air in which I stood, and they would, in a slow, graceful motion, accelerated somewhat towards the last, describe a downward and inward curve towards the lower part of my body before they dissolved. I thought of that elusive and yet clearly defined layer of mist that forms in the plane of contact between the cold air flowing from Mammoth Cave in Kentucky and the ambient air of a sultry summer day.

On another of the rare occasions when the mists had formed in the necessary density I went out again, put a stone in my pocket and took a dog along. I approached a shallow mist pool with the greatest caution. The dog crouched low, apparently thinking that I was stalking some game. Then, when I had arrived within about ten or fifteen yards from the edge of the pool, I took the stone from my pocket, showed it to the dog, and threw it across the pool as fast and as far as I could. The dog dashed in and tore through the sheet. Where the impact of his body came, the mist bulged in, then broke. For a while there were two sheets, separated by a more or less clearly defined, vertical layer of transparency or maybe blackness rather. The two sheets were in violent commotion,
approaching, impinging upon each other, swinging back again to complete separation, and so on. But the violence of the motion consisted by no means in speed: it suggested a very much retarded rolling off of a motion picture reel. There was at first an element of disillusion in the impression. I felt tempted to shout and to spur the mist into greater activity. On the surface, to both sides of the tear, waves ran out, and at the edges of the pool they rose in that same leisurely, stately way which struck me as one of the most characteristic features of that November mist; and at last it seemed as if they reared and reached up, very slowly, as a dying man may stand up once more before he falls. And only after an interval that seemed unconscionably long to me the whole pool settled back to comparative smoothness, though without its definite plane of demarcation now. Strange to say, the dog had actually started something, a rabbit maybe or a jumping deer, and did not return.

When fogs spread, as a rule they do so in air already saturated with moisture. What really spreads is the cold air which, by mixing with and thereby cooling the warmer, moisture-laden atmosphere, causes the condensation. That is why our fall mists mostly are formed in an exceedingly slight but still noticeable breeze. But in the case of these northern mist pools, whenever the conditions are favourable for their formation, the moisture of the upper air seems to be pretty well condensed as dew. It is only in the hollows of the ground that it remains suspended in this curious way. I cannot, so far, say whether it is due to the fact that where radiation is largely thrown back upon the walls of the hollow, the fall in temperature at first is very much slower than in the open, thus enabling the moisture to remain in suspension; or whether the hollows serve as collecting reservoirs for the cold air from the
surrounding territory – the air carrying the already condensed moisture with it; or whether, lastly, it is simply due to a greater saturation of the atmosphere in these cavities, consequent upon the greater approach of their bottom to the level of the ground water. I have seen a “waterfall” of this mist overflow from a dent in the edge of ground that contained a pool. That seems to argue for an origin similar to that of a spring; as if strongly moisture-laden air welled up from underground, condensing its steam as it got chilled. It is these strange phenomena that are familiar, too, in the northern plains of Europe which must have given rise to the belief in elves and other weird creations of the brain – “the earth has bubbles as the water has” – not half as weird, though, as some realities are in the land which I love.

Now this great, memorable fog of that November Friday shared the nature of the mist pools of the north in as much as to a certain extent it refused to mingle with the drier and slightly warmer air into which it travelled. It was different from them in as much as it fairly dripped and oozed with a very palpable wetness. Just how it displaced the air in its path, is something which I cannot with certainty say. Was it formed as a low layer somewhere over the lake and slowly pushed along by a gentle, imperceptible, fan-shaped current of air? Fan-shaped, I say; for, as we shall see, it travelled simultaneously south and north; and I must infer that in exactly the same way it travelled west. Or was it formed originally like a tremendous column which flattened out by and by, through its own greater gravity slowly displacing the lighter air in the lower strata? I do not know, but I am inclined to accept the latter explanation. I do know that it travelled at the rate of about six miles an hour; and its coming was observed somewhat in detail by two other observers besides myself – two
people who lived twenty-five miles apart, one to the north, one to the south of where I hit it. Neither one was as much interested in things meteorological as I am, but both were struck by the unusual density of the fog, and while one saw it coming from the north, the other one saw it approaching from the south.

I have no doubt that at last it began to mingle with the clearer air and to thin out; in fact, I have good testimony to that effect. And early next morning it was blown by a wind like an ordinary fog-cloud all over Portage Plains.

I also know that further north, at my home, for instance, it had the smell of the smoke which could not have proceeded from anywhere but the marsh; and the marsh lay to the south of it. That seemed to prove that actually the mist was spreading from a common centre in at least two directions. These points, which I gathered later, strongly confirmed my own observations, which will be set down further on. It must, then, have been formed as a layer of a very considerable height, to be able to spread over so many square miles.
