Holman pulled me away at last, and we retired to a point that made it possible for us to converse in low whispers without being heard.

"What will we do?" he gasped. "I can't stay there any longer! I want to get inside to the devil! I don't want to shoot him; I want to throttle him with my two hands!"

"But the entrance to the cavern is from somewhere on the other side of the hill," I remonstrated, as the young fellow raved about our helplessness.

"We must get there!"

"Don't lose your head about it," I remarked. "Keep cool and we'll win out in the long run."

It was useless to speak of patience to that boy at the moment. He clawed desperately at the slippery wall in an endeavour to find a path that would lead us to the opening on the other side by which Leith had made his entry, but the attempt appeared to be madness. A dozen times the youngster scrambled up rough portions that offered a slight footing, but each time he slipped back bruised and battered. He would listen to no arguments. The desire to get to the mouth of the cavern, and kill Leith before the morning, had produced an insanity, and we crawled and climbed along the face of those basalt cliffs in a manner that chilled my spinal marrow. Holman possessed the courage of a maniac. His imagination was blinded to the dangers that lay alongside the crumbling shelves of rock, and I scrambled behind him wondering dimly what would happen to Edith and her sister if an unkind fate flung us from the ledge into the darkness from which the soft croon of the chestnut clumps came up like a warning against our foolhardiness.

Holman paused at the end of a wearisome climb, and he drew himself upright. At that moment the cloud-harried moon dragged herself from beneath the pack, and the young fellow gave a cry of joy.

"We can do it from here, Verslun," he cried. "I see a path to the top. Come along, man!"

"What about Kaipi?" I gasped. "We'll never find our way back here."

"Let him sit there," he snorted. "Hurry or the moon will be under the clouds before we cross the cliff."
