She halted, facing, and lifting her hand to him.

'Your boat was broken, you say,' she said as he came. 'I tell you, your peril will be more extreme when you try the reefs again for an outlet, except you have a pilot of me.'

'You!' he said.

'Not I,' she laughed. 'The guide that I shall send will be a gull pure white, whose flight you shall follow. I have trusted you; do you trust me?'

'I will, I will.'

'A strict promise! Though you seem to be going upon certain death, you will trust and follow?'

'I will trust and follow, on my word, strictly kept as the oaths of the many.'

'Your pilot you will know by his call. Listen: "Diadyomene! Diadyomene!"' she shrilled like a sea-bird. 'It is my name—Diadyomene—of a good signification for you. I hold your promise; when you hear "Diadyomene" you are pledged to follow.'

She waited for no answer; with a gesture of farewell was away for the sea, from the moon-white sand springing into the shadows over the harsh interval of boulders. The vista let a vague moving shape show, lessening as she sped across the desolate chasm without. One strip of moonlight lay half-way, at the edge of the retreating sea. There a swift silver-white figure leapt clear, with dark hair flying an ineffectual veil, with arms rising wide in responsive balance to the quick free footing. It was gone—gone utterly—a plunge beyond restored her to her sea.

Christian stood motionless long after she had disappeared, so long that the moon paled, that dawn quickened in the east, that day spread wide. Responding to the daylight, broad awake rose reason to rebuke his senses for accepting fair words and a fair shape as warranty for fair dealing. And till midday reason domineered; while he abode the slack, while he battled for shore, while he mended and launched, while the cry 'Diadyomene! Diadyomene!' swept down on white wings, went before, shifted, wheeled; while, so guided, reefs and breakers threatened close on every hand, fell behind and left him scatheless.
