There they crouched with strained ears, waiting for the light which seemed as if it would never come, while the noise was crushing them back, as it were, upon themselves, and dulling their brains till all was to Cyril like some terrible dream. There were moments when he felt as if his senses were leaving him, and the sensation was almost welcome, for the agony at last grew greater than he could bear.

He had reached this pitch as he crouched there with his arm drawn tightly through John Manning’s, when he felt the man’s grasp upon him loosened, and the next moment he felt a thrust.

He knew directly what it meant. Following the movement, he became conscious of some pale, bluish-looking smoke on his left, and as this grew clearer, he realised that it was not smoke, but a thick mist between him and the coming light of day; but for a few minutes there was nothing more.

Then by slow degrees this dim, grey appearance grew and expanded, till the boy made out that the mist rose out of the depths before them, and at last that he and John Manning were crouching upon a ledge of rock on one side of a great gulf, down into which the waters thundered from their right, while overhead the wall of rock rose up nearly straight, the light of day being shut out by the dense mist which rose from below.

This light increased rapidly now in pale gleams from the left, and a faint, soft diffusion from above, showing that they were where a vast rift in the mountain joined at right angles the valley they had descended, while the rocky sides were so close that they nearly met overhead. But some time elapsed before they could make out more, the steamy mist obscuring everything, and preventing them from seeing anything of Perry or the colonel.

They had both risen to their feet, and clasping hands, began, as soon as it was possible to see a step or two, to try to penetrate farther in; but before they had gone half-a-dozen steps, John Manning, who looked misty and unsubstantial to Cyril, stopped short and pointed downward in front of him to where the rock looked slippery as glass.

“He went down there, sir,” he shouted, and loosening his grasp, threw himself down upon his chest, and wormed himself forward, so as to get his head over the gulf and look down.

Cyril watched the man in agony, fully expecting to see him glide forward out of sight; but in a few minutes he worked himself back, rose, and placed his lips to the boy’s ear again.

“Can’t see. All one thick cloud of spray.”

Cyril gave a great start, for at that moment, from out of the misty gloom, the colonel strode forward to meet them.
