At first the walking was not difficult, the trees standing far apart, and the soil beneath being covered with moss and long ferns; but after a time the woods grew denser, and it was only with considerable effort that they were able to move along. Every step seemed to make it worse. Long, slender trees shot up, not large enough to prevent their progress, but sufficient to form an impediment; and working their way among these proved very difficult, and very fatiguing. What was worse, the ground began to grow rougher at every step. Soon they emerged from the thick underbrush, and came to where the trees were larger, and farther apart from one another. But here the ground was spongy; and in every direction lay fallen trunks of trees, some prostrated but lately, others lying where they had lain for years, in every stage of decay. These they had to clamber over, or crawl under; and so it was that, in order to make any progress, they were compelled to use their hands as well as their feet. The soil beneath was hidden under a covering of moss; but it was swampy and spongy, and the soft earth was interlaced with long, fibrous roots, in which their feet caught at every other step. This moss overspread everything. It grew over the fallen trees; it enfolded in its green mantle the huge granite bowlders that from time to time upreared themselves beneath the trees.
At length they came to a slight rise in the ground, where the soil was dryer. Here the doctor paused, and the boys all flung themselves down on the ground, breathing heavily. They had walked for two hours now, without stopping, and began to feel exhausted. The doctor also showed signs of exhaustion. He said nothing, however, but scanned very narrowly the scene around him.
He found but little before his eyes that was in any way different from what he had been looking at for the last two hours. He could see a few paces before him, but no farther. There the trees arose, and the prospect terminated in the dim aisles of the forest, with their shadowy vistas. All around—before, behind, and on either side—it was the same. There was the dense forest, just such a forest as they had traversed—it spread all around them. The only place where a view could be had for any distance was overhead.
But even here it was no better. For the boys, as they flung themselves down, saw that during their journey a change had taken place overhead. The blue sky was no longer to be seen. In its place there came close down a dull, gray, indistinct haze, which descended even to where they lay, hiding the tree tops from view.
It was the fog.
Such a common circumstance elicited no surprise, of course. It was no more than might have been expected. The wind had changed, and the fog of the Bay of Fundy had rushed over Blomidon, and they, in those dim woods, were now enveloped in its folds. Nor was it so much a matter of regret to them as it might have been under other circumstances. Here in the woods it made but little difference in their situation. Even if the sun were shining brightly overhead, the ground beneath would be just as swampy, the fallen trees as troublesome, the underbrush as thick.
Whatever were the doctors own private feelings, he kept them to himself, and surveyed the scene in silence. At length he made up his mind as to his course, and once more started for his onward journey.
The journey was the same as before. Sometimes a great growth of underbrush would impede their progress, and that underbrush would vary from the tall, slender stems of the young maples to the dense and prickly spines of the young spruces. At other times the trees would stand apart, the scene would expand, and they would be encircled by a dense array of forest columns, between which the view was lost in shadow and gloom. Sometimes they plunged into swamps, unawares; at other times they tore their way through ferns and trailing plants; again they were compelled to climb over fallen trees, or crawl under them. Once they came to a place which was quite bare of trees, but overgrown with fire weed and blueberries. Such places as these were known to them by the name of “Barrens,” and on this occasion they made use of it to take a long rest. The doctor again looked all around him thoughtfully, and appeared buried in profound reflection.
It was here that a thought flashed to the minds of all the boys.
It was this.
