It was necessary that he should find such a spot, for the ledge had grown narrower and in another yard died completely away. So, raising his hands to their full extent, he found a place for one foot, then for the other, repeated the experiment, and was just going to draw himself up to a ledge similar to that which he had just left, when one foot slipped from the stone upon which it rested, and had the lad lost his nerve he must have fallen headlong.

But he held on tightly, waited a minute to let the jarring sensation pass away, depending upon his hands and one foot. Then calmly searching about he found firm foothold, raised himself, and the next moment he was on the green ledge.

“Wouldn’t have done to tumble,” he said with a hall laugh. “Fall’s one thing, a dive another. I suppose the water’s pretty deep down there.”

The ledge he was now on was fully a foot wide, and the refuse and fish bones with which it was strewn told plainly enough that in the spring time it was the resting—perhaps nesting—place of the sea-birds which swarmed along the coast.

As he stood facing the rock he found directly that he could not get any farther to his right, and a little search proved that from this ledge he could get no higher, not even had he been provided with a ladder. Even if a rope had been lowered down to him from the top of the cliff, it would have been of no avail, for he realised now that which he could not see from the hole by which he had escaped, to wit, that the cliff projected above the opening, and a lowered down rope would have hung several feet right away clear.

“Get farther along,” he said coolly; and he edged himself slowly along, taking hold of every prominence he found to steady himself, and passing cautiously along the rough ledge over the hole, and then onward for forty or fifty feet, where a rift ran upward, and, by cautious climbing, he mounted slowly till he was on a fresh ledge, a few feet above which was another rift, and he climbed again, to come to a depression or niche, where he stopped to rest.

“No occasion to hurry,” he said to himself, and as there was plenty of room he sat down and gazed out to sea, noting a sail far away to the right, but the vessel was a schooner—it was not that which he sought.

He was apparently cool enough, but his pulses beat more rapidly than was consistent with the exertion through which he had gone, and being after a few minutes eager now to get his task at an end, he tried to the left, to find no way up there, to the right, but everywhere the rock was perpendicular, and offered no foothold; or else sloped outward, and concealed what was above.

He tried again and again, hoping against hope, but without result.

“Must be a way up,” he said, evidently considering that there must be because he wanted it, and he took tightly hold of a rough corner and leaned out a little to gaze upward, to find, in whichever direction he looked, right or left, there was nothing but rugged limestone, which had been splintered and moulded by time till there was not a spot where the most venturesome climber could obtain foothold; in fact, above him he could not see a spot where even the sea-birds had been in the habit of finding a resting-place.
