‘O, let us sit and look at it!’ she said; and they turned their backs upon the equatorial and the southern glories of the heavens to this new beauty in a quarter which they seldom contemplated.

The lustre of the fixed stars was diminished to a sort of blueness. Little by little the arch grew higher against the dark void, like the form of the Spirit-maiden in the shades of Glenfinlas, till its crown drew near the zenith, and threw a tissue over the whole waggon and horses of the great northern constellation. Brilliant shafts radiated from the convexity of the arch, coming and going silently. The temperature fell, and Lady Constantine drew her wrap more closely around her.

‘We’ll go down,’ said Swithin. ‘The cabin is beautifully warm. Why should we try to observe to-night? Indeed, we cannot; the Aurora light overpowers everything.’

‘Very well. To-morrow night there will be no interruption. I shall be gone.’

‘You leave me to-morrow, Viviette?’

‘Yes; to-morrow morning.’

The truth was that, with the progress of the hours and days, the conviction had been borne in upon Viviette more and more forcibly that not for kingdoms and principalities could she afford to risk the discovery of her presence here by any living soul.

‘But let me see your face, dearest,’ he said. ‘I don’t think it will be safe for you to meet your brother yet.’

As it was too dark to see her face on the summit where they sat they descended the winding staircase, and in the cabin Swithin examined the damaged cheek. The line, though so far attenuated as not to be observable by any one but a close observer, had not quite disappeared. But in consequence of her reiterated and almost tearful anxiety to go, and as there was a strong probability that her brother had left the house, Swithin decided to call at Welland next morning, and reconnoitre with a view to her return.

Locking her in he crossed the dewy stubble into the park. The house was silent and deserted; and only one tall stalk of smoke ascended from the chimneys. Notwithstanding that the hour was nearly nine he knocked at the door.
