It's half an hour's walk from Gunwalloe to Michael's Crag; and by the time Trevennack reached the mouth of the gully the sands were almost covered; so for the first time in fifteen years he was forced to take the path right under the cliff to the now comparatively distant island, round whose base a whole waste of angry sea surged sullenly. On the way they met a few workmen who, in answer to their inquiries, could give them no news, but who turned back to aid in the search for the missing young lady. When they got opposite Michael's Crag, a wide belt of black water, all encumbered with broken masses of sharp rock, some above and some below the surface, now separated them by fifty yards or more from the island. It was growing dark fast, for these were the closing days of August twilight; and dense fog had drifted in, half obliterating everything. They could barely descry the dim outline of the pyramidal rock in its lower half; its upper part was wholly shrouded in thick mist and drizzle. With a wild cry of despair, Trevennack raised his voice, and shouted aloud, "Cleer, Cleer! where are you?" That clarion voice, as of his namesake angel, though raised against the wind, could be heard above even the thud of the fierce breakers that pounded the sand. On the highest peak above, where she sat, cold and shivering, Cleer heard it, and jumped up. "Here! here! father!" she cried out, with a terrible effort, descending at the same time down the sheer face of the cliff as far as the dashing spray and fierce wild waves would allow her. No other ear caught the sound of that answering cry; but Trevennack's keen senses, preternaturally awakened by the gravity of the crisis, detected the faint ring of her girlish voice through the thunder of the surf. "She's there!" he cried, frantically, waving his hands above his head. "She's there! She's there! We must get across and save her." For a second Mrs. Trevennack doubted whether he was really right, or whether this was only one of poor Michael's hallucinations. But the next moment, with another cry, Cleer waved her handkerchief in return, and let it fall from her hand. It came, carried on the light breeze, and dropped in the water before their very eyes, half way across the channel. Frenzied at the sight, Trevennack tore off his coat, and would have plunged into the sea, then and there, to rescue her. But the workmen held him back. "No, no, sir; you mustn't," they said. "No harm can't come to the young lady if she stops there. She've only got to sit on them rocks there till morning, and the tide'll leave her high and dry right enough, as it always do. But nobody couldn't live in such a sea as that--not Tim o' Truro. The waves 'u'd dash him up afore he knowed where he was, and smash him all to pieces on the side o' the island."
