Following it up, then, our hunters entered the ravine. They kept for some distance along one side—just by the edge of the deep snow; but at length, the track indicated where the bear had crossed to the other side; and of course they were compelled to cross likewise.

This deep snow was the accumulated deposits of different storms that had occurred during the winter; and, shadowed from the sun by the long branches of evergreen pines from both sides stretching outward over the ravine, it had remained without melting. There was a crust over it—strong enough to carry a man on skidors, but not without them, unless he proceeded with care and caution. The bear had gone over it; but these animals, notwithstanding their enormous weight and bulk, can pass over ice or crusted snow that will not carry a man. Their weight rests upon four points instead of two; and as they need only lift one foot at a time, they still have three points of support. A man must also lift one foot, which leaves him only one to stand upon; and therefore his whole weight presses upon a single point, and so endangers his breaking through. The great length of a bear’s body, moreover, and the vast stretch between his fore and hind legs give him an additional advantage—enabling him to distribute his weight over a large surface—and this is why he can shuffle over ice or snow-crust, that may be too weak to carry a human being. Every boy knows—at least every boy who has skated or ventured upon a frozen pond—that by creeping on hands and knees, or, more certain still, by sprawling along on the breast, ice may be passed over, that would not bear the same boy in an erect attitude.

Such advantage, then, had the bear which our young hunters were tracking up; and it would have been well for them—at least for Pouchskin—had they thought of it. They did not. They supposed that where a great heavy animal like a bear had gone they might go too; and, without further reflection, they stepped out upon the deep bed of snow.

Alexis and Ivan being light weights passed over the snow safely enough; but Pouchskin, weighing nearly as much as both of them—and further loaded with a ponderous wood-axe and his huge gun, to say nothing of sundry well-filled pockets and pouches—was more than the crust would carry. Just when he had got about halfway across, there was heard a tearing crash; and before the boys could turn to inquire the cause, Pouchskin had disappeared, and all his paraphernalia along with him!

No, not quite all. There was seen about two feet of the barrel of his gun above the surface; and as that still pointed upward—while it moved around the circular hole through which the old guardsman had fallen—the boys concluded that the piece was in his hands, and that Pouchskin was still upon his feet.

At the same instant a voice reached their ears—in a hollow sepulchral tone, like that of a man speaking from the bottom of a well, or through the bung-hole of an empty cask!

Notwithstanding its baritone notes, the boys perceived that the exclamations made by the voice were not those of terror, but rather of surprise, followed by a slight laugh. Of course, therefore, their attendant had received no injury, nor was he in any danger; and, assured of this, Ivan first, and then Alexis, broke out into yells of laughter.

On cautiously approaching the trap-like hole, through which Pouchskin had disappeared, their merriment burst forth afresh, at the ludicrous spectacle. There stood the old guardsman, like a jack-in-the-box in the centre of a hollow funnel-shaped cylinder which he had made in the snow. But what was strangest of all, there was no snow among his feet: on the contrary, he was up to his knees in water, and not stagnant water either, but a current, that ran rapidly underneath the snow, and had swished the crusted fragments from the spot where he was standing!

A stream, in fact, ran down the ravine; and, although the snow completely hid it from view, there it was, rushing along underneath through a tunnel which it had melted out for itself—the snow forming a continuous bridge above it.

The boys did not know all this—for they could only just see the top of Pouchskin’s head, with his long arms holding the gun—but they could hear the rushing noise of the water, and Pouchskin reported the rest.
