At this juncture the Irish lad made a proposition which his companion accepted, for he thought it promised them much saving in time and travel.

It was quite certain that the false trail followed pretty much the same direction as the true one: at any rate there could be no doubt that it crossed the stream which had stopped them, so instead of picking their way back for several miles, they decided to keep along the edge of the water itself until they struck the path.

To make sure of avoiding another blunder, one should have gone up and the other down stream, for manifestly they could not be certain they were above or below the true path; but each felt too strong a misgiving about such a course. Their surroundings required mutual support.

Beside this, they were convinced that the trail which they wished to recover lay above instead of below, so that, when making their way they were not held back by any doubt, though each could not fail to see that it was only a piece of guess-work.

Fortunately for their peace of mind, they were right, and the plan saved them much time and travel. They had not gone very far, when they came upon the path, marked so distinctly that there could be no possible mistake.

The width of the stream was about the same as below. The water was smooth, deep, clear and sluggish. The bank sloped gently down from each side and on the other sh.o.r.e were plainly seen the prints of the hoofs where the animals had left the water. It was so deep that whoever went over there had done so by floating or swimming.

The crossing was so far above the point where the cascades began, that nothing was to be feared from them. The clumsiest raft could be ferried over by a child before it would drift into danger, while in case of swimming, the peril was still less.

"If it wasn't so chilly," said Fred, "I would propose that we swim the stream."

Terry shivered and shook his head.

"We must go over on a raft; it is not only cowld, but is gittin'

cowlder."

"There's a storm brewing; it looks as black as ink off yonder."

At this moment the boys made a discovery which both pleased and alarmed them. Such a float as they needed was at their call. There lay a half dozen logs and trees fastened together by several withes, and with enough buoyancy to bear them to the other side. Even the pole to be used in propulsion lay upon the heavy timbers that were pulled just far enough against the bank to prevent them floating off with the current.

While it was pleasant to know that they would not have to go through the labor of constructing any thing of the kind, yet there was a cause for fear in the presence of the structure which led them to hesitate several minutes before using it.

It proved that some one had crossed from the other side upon it, while the withes were so white and fresh at the angles, where they were twisted open, as to show that the raft had been made but a short time.

The natural question was as to who could have been coming from the other way.

"I know," said Terry, compressing his lips and shaking his head.

"Who?"

"Winnebagos; they're so plintiful that it couldn't have been any one ilse, for they wouldn't have had a chance."

"I suppose you are right," remarked Fred thoughtfully, "for they do seem to be almost everywhere, though I can't understand why they should be coming this way."

"Suppose there was but one of the spalpeens, and he'd been out on a scout, and was on his way back to the rist of the spalpeens with the news, would it be onraisonable to think he would take a little pains to kaap his leggins and moccasins from gittin' damp enough to give him cowld?"

"Well, I can think of no better reason than that, and am willing to believe it is correct, but don't you see, Terry, that all this goes to prove that we have lost a dangerous amount of time? We ought to have been many miles further on the road than we are."

"The buffalo bull had a good deal to do with our impolite tarryin', and as he is slaapin' with his four mithers, I maan his forefathers, let him rist in pace."

The boys did not allow their words to delay their hands. The raft was shoved clear, and the two took their positions upon it, Fred holding the pole, while his companion looked after the guns. They were astonished to find, directly after leaving land, that the pole, which was nearly twenty feet in length, would not reach bottom.

This compelled them to use it as a paddle. The progress was slow, but the distance was so slight that it did not take them long to reach the other bank, where they set the structure adrift, so that it could not be used by any one else.

Looking directly up stream, where the sky was in plain sight, its blackness startled even the boys, who were used to seeing the most violent changes of temperature. The hue was not of the dark blue which often gives warning of the coming tempest, but there was a greenish tinge to the blackness that would have awed any one.

While they looked, a zigzag ribbon of flame fluttered across the darkened portion, accompanied by a crash that seemed to shiver the earth. Fred Linden, who happened to be staring straight at the fiery burst, saw the upper part of a large cypress that leaned over the water, leap from the trunk as though it had been sawn short off and flung into the water.

It was all ablaze, and, falling upright into the current, kept its equilibrium, that is, it did not fall to any side, but swept slowly downward as upright as when on the tree, and suggested that some giant as big as the Statue of Liberty was walking beneath, with an enormous torch held above his head to light his path.

"Did ye iver see the like?" asked Terry.

"No; it is wonderful."

[Ill.u.s.tration: "Did ye iver see the like?" asked Terry.]

Although it was about mid-day, the heavens were so overcast that the gloom was like night itself. At the same time the darkness had a ghastly tinge which made the faces of the boys, when they looked at each other, livid and unearthly.

The scene was so impressive that they stood motionless, watching the flaming tree and the inky heavens beyond. Suddenly in the sky they saw a figure that resembled a vast balloon slightly inclined to one side, and spinning on its axis with inconceivable swiftness.

At the bottom the snout-like appendage wavered off to one side as though the amazing velocity of the upper part was twisting it loose. A similar formation appeared a few minutes after a short distance behind.

And now began the most extraordinary exhibition of all. Imagine two whirling balloons, a hundred feet in height, and so black that they stood out from the surrounding gloom, showing like pitch against the dimly lit sky behind. They began a witches' waltz in the firmament, sometimes leaning far backward, then dancing forward, as if saluting each other, then "balancing," then dancing up and down, then so far away from each other that one would pa.s.s out of the field of vision, soon to reappear, however. At times they seemed as if about to rush into each other's arms, and then they coquetted away again and resumed the weird dance in the skies.

You understand that I am trying to describe one of those terrible visitations of the west known as a cyclone. Little was heard of them a century ago, and the balloon to which I have compared the form of the ghostly dancers, was unknown to the lads, who watched the exhibition with an interest that was not turned into terror, as it would have been to-day, by the knowledge of the awful power for death and destruction that lies within that concentration of electricity in its most fateful form.

It seemed a long time that this strange scene lasted, though it could not have been many seconds. Suddenly, while the balloon-like forms were saluting each other, they rushed together. There was no shock perceivable when they met, but there were vivid flashes from within the murky folds, as the heat lightning sometimes plays among the clouds at the close of a warm day.

Having met, the forms engaged in a wrestling bout. Round and round they spun with the same bewildering swiftness, leaning far to one side, as though about to fall, and all the time whirling with such speed on the one spiral leg that it seemed unable to keep pace with the bulkier part above.

CHAPTER x.x.xIII.

FRED LINDEN AWAKENS TO AN ALARMING FACT.

The approach of the cyclone was attended by an appalling roar, and a ma.s.s of branches and trees flying through the air, which warned the boys of their danger.

"Terry, it won't do to stay here," shouted Fred, casting about for some place of refuge; "where shall we go?"

Quite close to the stream which they had just crossed was an enormous rock. Its irregular surface, a dozen feet in extent each way, must have reached far down in the ground, so that nothing could have been more immovable. It was not the refuge that the boys would have taken, had they been given time to hunt for one, but surely they could not have found a better.

A couple of leaps took Terry to the place, and, as he threw himself on his face, Fred was directly behind him. As they lay, the shelving rock was less than two feet above their heads. Though they could hear, they could not see what was coming. They could look to the right and left, but only for a few seconds in front.

Using their eyes as best they could, they saw the air filled with leaves, twigs, branches, huge limbs and trunks, which spun forward and over and over, like so many feathers in a tornado.

The first shock that came to the boys crouching behind the rock was a dead thump near their heads. An uprooted tree had been hurled from some point above, like an enormous spear, and, striking the rock at a slant, slid over the rough surface like the finger of a player over the face of a tambourine and out beyond, hunting for some spot where it could penetrate. It found it on the ground, but it was instantly wrenched loose by the resistless power that had first thrown it forward, and went end over end into the general wreck and ruin beyond.

The next sight which startled the boys was on their left, directly over the stream. The air was filled apparently with snow, as if a violent squall had suddenly sprung up. It was accompanied by a hissing noise, which mingled with the fearful roar that had not stopped and was like that of the stormy Atlantic beating upon the rock-bound coast.

Striking the stream, the cyclone whirled most of the water from its bed, scattered the mist and foam among the trees, and saturated the boys where they lay. The huge torch was quenched as suddenly as it was lighted.
