Further advance or retreat was alike impossible. On three sides roared the cheated torrent; behind and above, canopy-wise, towered the cliff. If the evidence of ominous fissures and lateral cracks were to be read aright, there was no telling the moment when they might be buried under another avalanche of thousands of tons of stone.

Every tide deepened the sap. They were imprisoned in one of nature’s own quarries, where work was relentless and unceasing.

Once again idle chance had decided that Maseden should save Nina and Sturgess Madge. Not that it mattered a jot. If ever four people were in hapless case, it was they. For a time even to Maseden, who had never lost faith in his star, it seemed that the best fortune that could now befall would be for the trembling rock overhead to crash down on them.

The din was terrific, and the water level was rising so rapidly that five minutes after they had gained their present position the boulders to which they had sprung from the sundering platform of logs were a foot deep in the swirling current. Each of the girls, wholly unconscious of her attitude, clung despairingly to the man at her side and watched the climbing surge with somber eyes.

They were too stunned to yield to fear, and the life of the past fortnight had so steeled their nerves and strengthened their bodies that fainting was no longer the readiest means of obtaining a merciful respite from present horrors. Rather did a bitter rage possess them, for it was a harsh and monstrous decree of fate which had not only robbed them of a hard-won means of escape, but immersed them in a veritable condemned cell.

Maseden, like the others, was watching the encroaching water-line in a benumbed way when he became aware that Nina was speaking. He looked into her drawn face and tried to smile, though a sort of mist clouded his eyes.

“What is it, girlie?” he said, putting his mouth close to her ear and addressing her as though she were a timid child.

“Is this the end?” she cried, imitating him.

“Not yet, anyhow,” and he gave her a reassuring hug.

“Tell me—if you think—we have only a few more minutes,” she said.
