“I’ll strike a light after we get down a bit—so come along,” said Captain Dan, leaving the office and leading the way.

On reaching the entrance to the shaft, Oliver Trembath looked down and observed a small speck of bright light in the black depths.

“A man coming up—wait a bit,” said the captain in explanation.

Presently a faint sound of slow footsteps was heard; they grew gradually more distinct, and ere long the head and shoulders of a man emerged from the hole. Perspiration was trickling down his face, and painting him, streakily, with iron rust and mud. All his garments were soaking. He sighed heavily on reaching the surface, and appeared to inhale the fresh air with great satisfaction.

“Any more coming?”

“No, Captain Dan,” replied the man, glancing with some curiosity at the tall stranger.

“Now, sir, we shall descend,” said the captain, entering the shaft.

Oliver followed, and at once plunged out of bright sunshine into subdued light. A descent of a few fathoms brought them to the bottom of the first ladder. It was a short one; most of the others, the captain told him, were long ones. The width of the shaft was about six feet by nine. It was nearly perpendicular, and the slope of the ladders corresponded with its width—the head of each resting against one side of it, and the foot against the other, thus forming a zigzag of ladders all the way down.

At the foot of the first ladder the light was that of deep twilight. Here was a wooden platform, and a hole cut through it, out of which protruded the head of the second ladder. The Captain struck a light, and, applying it to one of the candles, affixed the same to the front of Oliver’s hat. Arranging his own hat in a similar way, he continued the descent, and, in a few minutes, both were beyond the region of daylight. When they had got a short way down, probably the distance of an ordinary church-steeple’s height below the surface, Oliver looked up and saw the little opening far above him, shining brightly like a star. A few steps more and it vanished from view; he felt that he had for the first time in his life reached the regions of eternal night.

The shaft varied in width here and there; in most places it was very narrow—about six feet wide—but, what with cross-beams to support the sides, and prevent soft parts from falling in, and other obstructions, the space available for descent was often not more than enough to permit of a man squeezing past.
