That the warning was by no means superfluous was shown by a sudden stagger on the part of Philip. He reeled for a moment, then, with a great effort, recovered his balance. He had been so absorbed in watching Alma’s progress in front, that he had quite neglected the attention due to his own footing. Now this cannot be done with impunity upon the edge of a knife-like ridge about one thousand feet in mid-air—as he learned when he found himself within an ace of plunging into space. Fordham, for a moment, thought he had gone.

“You’ll add to the record of this much maligned climb, Phil, if you don’t mind,” he said. “What’s the row? Feel heady?”

“Not a bit. Only made a slip. Sha’n’t do it again though. I say, Wentworth, how far would a fellow fall here—on this side?”

“Oh, about eight hundred feet. Then he’d go footballing two or three hundred more,” was the nonchalant reply. “I wouldn’t try it, though, if I were you.”

They were off the arête now, and paused to rest under the rocks to allow the others time to come up.

“Hallo, Gedge!” continued Wentworth, as the addressed came crawling along on all-fours, and that very gingerly. “I thought you felt like doing this climb on one leg, and instead of that it seems to take you all four.”

“You people go on at such a rate. Besides, I find I’m not up to much on a place like this. No, I’ll climb down from the ‘one-leg’ position, absolutely and unreservedly.”

“There’s another man who isn’t up to much on a place like this,” said Fordham, with a dry chuckle.

Scott, to whom this remark referred, had nearly reached the middle of the arête. He, too, was creeping on hands and knees. But suddenly his heart seemed to fail him, for there he sat, straddling the ridge, one leg on each side of the mountain, the very picture of wild panic. His hat had blown off, and hung by a string over his shoulder, and he dared not move a finger to replace it. His hands shook as he grasped the rock in a strained, terror-stricken grasp, and his eyes seemed to start from his deadly white face.

“Oh, help me off!” he cried piteously. “For Heaven’s sake, some of you help me off!”
