What was he doing? She looked over his shoulder upon the paper, and saw figures and signs. When he had jotted down something he went to the telescope again.

‘What are you doing to-night?’ she said in a low voice.

Swithin started, and turned. The faint lamp-light was sufficient to reveal her face to him.

‘Tedious work, Lady Constantine,’ he answered, without betraying much surprise. ‘Doing my best to watch phenomenal stars, as I may call them.’

‘You said you would show me the heavens if I could come on a starlight night. I have come.’

Swithin, as a preliminary, swept round the telescope to Jupiter, and exhibited to her the glory of that orb. Then he directed the instrument to the less bright shape of Saturn.

‘Here,’ he said, warming up to the subject, ‘we see a world which is to my mind by far the most wonderful in the solar system. Think of streams of satellites or meteors racing round and round the planet like a fly-wheel, so close together as to seem solid matter!’ He entered further and further into the subject, his ideas gathering momentum as he went on, like his pet heavenly bodies.

When he paused for breath she said, in tones very different from his own, ‘I ought now to tell you that, though I am interested in the stars, they were not what I came to see you about. . . . I first thought of disclosing the matter to Mr. Torkingham; but I altered my mind, and decided on you.’

She spoke in so low a voice that he might not have heard her. At all events, abstracted by his grand theme, he did not heed her. He continued,—

‘Well, we will get outside the solar system altogether,—leave the whole group of sun, primary and secondary planets quite behind us in our flight, as a bird might leave its bush and sweep into the whole forest. Now what do you see, Lady Constantine?’ He levelled the achromatic at Sirius.
