The dreadful journey was begun. Slowly and cautiously the pair groped their uncertain way along that narrow ledge, each pausing until the other was ready to proceed; and Lance with difficulty restrained a shudder as once during the passage he felt that the heel of his boot actually projected over the awful ledge. A dozen times he felt outwards with his foot to ascertain whether the chasm was passed or not, and at last, with an involuntary sigh of ineffable relief he found that there was solid ground beyond him as far as his foot could reach.

“Now stand quite still for a moment, Blanche,” he said. “I am about to light another match.”

He did so, and found that they had indeed achieved the awful passage—with some six inches to spare. At his very feet still yawned the hungry gulf, but they were beyond it, thank God, and once more in comparative safety. Hastily seizing his companion’s hand, he hurried her far enough away from the spot to prevent her seeing the deadly nature of the peril to which they had been exposed, and then removed the bandage from her eyes.

“There,” he said cheerfully, “we are past the chasm at last, and now you may have the use of your eyes once more.”

Lighting another match, the imprisoned pair now pressed forward as rapidly as circumstances would permit, taking care to keep a match always alight in order that they might not stumble unawares upon a possible second chasm or other danger. They pressed forward in silence, except for an occasional word of caution or encouragement from Lance, both being far too anxious to admit of anything like a connected conversation.

Suddenly Lance stopped short. To his sense of hearing, acutely sharpened by the long-continued death-like silence of the place, there had come a sound, fainter than the breathing of a sleeping infant, a mere vibration of the air, in fact, but still—a sound.

What was it? He knelt down and placed his ear close to the ground. Yes; now he caught it a trifle more distinctly; the faintest murmur still, but with something of individuality appertaining to it. It rose and fell rhythmically, swelling gradually in volume, and then subsiding again into silence.

“Hurrah!” he shouted joyously. “The sea! the sea! I can hear it. Courage, Blanche darling, our journey is nearly at an end. One short half-hour at most, and, with God’s help, we shall be free.”

Again they pushed eagerly forward; with high hopes and grateful hearts now, and with every yard of progress the gladdening sound rose clearer and clearer still until there could no longer be any possible mistake about it; it was indeed the regular beat of surf upon the shore.

At length a faint gleam of light became perceptible upon the rocky walls in front; gradually it strengthened, until the more prominent projections of the rock began to stand out bold and black against the lighter portions beyond; and at last, as the path curved gently round, their eager eyes were gladdened by the sight of an opening into which the sea was sweeping with a long lazy undulating motion until it curled over and plashed musically upon a narrow strip of sandy beach.
