But as we looked around us, thankful for our safety, we grasped each other more closely, and a low cry of fear emphasized Norah’s shudder—for a terrible thing began to happen.

The whole surface of the bog, as far as we could see it in the dim light, became wrinkled, and then began to move in little eddies, such as one sees in a swollen river. It seemed to rise and rise till it grew almost level with where we were, and instinctively we rose to our feet and stood there awestruck, Norah clinging to me, and with our arms round each other.

The shuddering surface of the bog began to extend on every side to even the solid ground which curbed it, and with relief we saw that Dick and Joyce stood high up on a rock. All things on its surface seemed to melt away and disappear, as though swallowed up. This silent change or demoralization spread down in the direction of Murdock’s house—but when it got to the edge of the hollow in which the house stood, it seemed to move as swiftly forward as water leaps down a cataract.

Instinctively we both shouted a warning to Murdock—he, too, villain though he was, had a life to lose. He had evidently felt some kind of shock or change, for he came rushing out of the house full of terror. For an instant he seemed paralyzed with fright as he saw what was happening. And it was little wonder! for in that instant the whole house began to sink into the earth—to sink as a ship founders in a stormy sea, but without the violence and turmoil that marks such a catastrophe. There was something more terrible—more deadly in that silent, causeless destruction than in the devastation of the earthquake or the hurricane.

The wind had now dropped away; the morning light struck full over the hill, and we could see clearly. The sound of the waves dashing on the rocks below, and the booming of the distant breakers filled the air—but through it came another sound, the like of which I had never heard, and the like of which I hope, in God’s providence, I shall never hear again—a long, low gurgle, with something of a sucking sound; something terrible—resistless—and with a sort of hiss in it, as of seething waters striving to be free.

Then the convulsion of the bog grew greater; it almost seemed as if some monstrous living thing was deep under the surface and writhing to escape.

By this time Murdock’s house had sunk almost level with the bog. He had climbed on the thatched roof, and stood there looking towards us, and stretching forth his hands as though in supplication for help. For a while the superior size and buoyancy of the roof sustained it, but then it too began slowly to sink. Murdock knelt, and clasped his hands in a frenzy of prayer.

And then came a mighty roar and a gathering rush. The side of the hill below us seemed to burst. Murdock threw up his arms—we heard his wild cry as the roof of the house, and he with it, was in an instant sucked below the surface of the heaving mass.

Then came the end of the terrible convulsion. With a rushing sound, and the noise of a thousand waters falling, the whole bog swept, in waves of gathering size, and with a hideous writhing, down the mountain-side to the entrance of the Shleenanaher—struck the portals with a sound like thunder, and piled up to a vast height. And then the millions of tons of slime and ooze, and bog and earth, and broken rock swept through the Pass into the sea.

Norah and I knelt down, hand-in-hand, and with full hearts thanked God for having saved us from so terrible a doom.
