“There,” said the convict, as he secured the knot firmly. “Now listen: I shall take hold of your hand to hold it tightly, and I want you to try and make yourself part of me for the next ten minutes, obeying every touch, and taking step for step with me. Don’t pause, don’t hesitate; only keep on feeling that I am guiding you safely through the darkness. There is no risk if you do this.”

“I’m ready,” said Nic; “only begin quickly, please, and let’s get it done.”

“Then come along.”

Nic felt his hand seized in a strong, firm grip, and followed as he was led, hesitating once, and showing a disposition to hang back, but it was only for a moment. The next he was walking slowly and steadily behind the convict, who led him between two or three bushes, and then along a narrow shelf which passed round the end of the rock slip; and as soon as it was cleared the buttress at that end grew still more narrow, so that the boy felt his right arm brushing against the perpendicular rock wall, while his left hung free.

He could not see, but he knew that his left fingers must be pointing down into the tremendous gulf; and in imagination he saw with wonderful accuracy through the golden transparent air the various plants which grew from the interstices of the titanic wall, the bushes and shrubs, the pendent vines and clinging creepers, the shelves and faults in the strata here and there deeper down, and then lower and lower still the gaps and hollows whence stalwart trees had risen from seeds dropped or hidden by some bird—trees which had grown out almost horizontally, and then curved up into their proper vertical position, to rise up and up as the years rolled on, though now they looked mere shrubs a handbreadth high.

And as the boy walked on he saw lower and lower the forest monarchs dwarfed to shrubs, and lower still patches of timber that were indistinct and looking hardly more than grass, while here and there the light of the setting sun gleamed ruddily from the water of the chain of lakes.

It was but the picture raised by memory from where it was printed upon Nic’s mind, but it was very accurate, and almost exactly what he would have seen had his eyes been free during that long, long walk, as it seemed—a walk of a few brief minutes though, and then his hand was dropped.

“Don’t do that till you’ve unbound my eyes,” said Nic sharply.

“Why not, boy? we are in safety now.”

Nic’s breath was exhaled in a hoarse sigh as he felt the kerchief drawn from his face, and he looked round to see that they were among trees.
