Lady Constantine then had the pleasure of beholding a waggon, laden with packing-cases, moving across the field towards the pillar; and not many days later Swithin, who had never come to the Great House since the luncheon, met her in a path which he knew to be one of her promenades.

‘The equatorial is fixed, and the man gone,’ he said, half in doubt as to his speech, for her commands to him not to recognize her agency or patronage still puzzled him. ‘I respectfully wish — you could come and see it, Lady Constantine.’

‘I would rather not; I cannot.’

‘Saturn is lovely; Jupiter is simply sublime; I can see double stars in the Lion and in the Virgin, where I had seen only a single one before. It is all I required to set me going!’

‘I’ll come. But — you need say nothing about my visit. I cannot come to-night, but I will some time this week. Yet only this once, to try the instrument. Afterwards you must be content to pursue your studies alone.’

Swithin seemed but little affected at this announcement. ‘Hilton and Pimm’s man handed me the bill,’ he continued.

‘How much is it?’

He told her. ‘And the man who has built the hut and dome, and done the other fixing, has sent in his.’ He named this amount also.

‘Very well. They shall be settled with. My debts must be paid with my money, which you shall have at once — in cash, since a cheque would hardly do. Come to the house for it this evening. But no, no — you must not come openly; such is the world. Come to the window — the window that is exactly in a line with the long snowdrop bed, in the south front — at eight to-night, and I will give you what is necessary.’

‘Certainly, Lady Constantine,’ said the young man.

At eight that evening accordingly, Swithin entered like a spectre upon the terrace to seek out the spot she had designated. The equatorial had so entirely absorbed his thoughts that he did not trouble himself seriously to conjecture the why and wherefore of her secrecy. If he casually thought of it, he set it down in a general way to an intensely generous wish on her part not to lessen his influence among the poorer inhabitants by making him appear the object of patronage.

While he stood by the long snowdrop bed, which looked up at him like a nether Milky Way, the French casement of the window opposite softly opened, and a hand bordered by a glimmer of lace was stretched forth, from which he received a crisp little parcel — bank-notes, apparently. He knew the hand, and held it long enough to press it to his lips, the only form which had ever occurred to him of expressing his gratitude to her without the incumbrance of clumsy words, a vehicle at the best of times but rudely suited to such delicate merchandise. The hand was hastily withdrawn, as if the treatment had been unexpected. Then seemingly moved by second thoughts she bent forward and said, ‘Is the night good for observations?’

‘Perfect.’

She paused. ‘Then I’ll come to-night,’ she at last said. ‘It makes no difference to me, after all. Wait just one moment.’

He waited, and she presently emerged, muffled up like a nun; whereupon they left the terrace and struck across the park together.

Very little was said by either till they were crossing the fallow, when he asked if his arm would help her. She did not take the offered support just then; but when they were ascending the prehistoric earthwork, under the heavy gloom of the fir-trees, she seized it, as if rather influenced by the oppressive solitude than by fatigue.

Thus they reached the foot of the column, ten thousand spirits in prison seeming to gasp their griefs from the funereal boughs overhead, and a few twigs scratching the pillar with the drag of impish claws as tenacious as those figuring in St. Anthony’s temptation.

‘How intensely dark it is just here!’ she whispered. ‘I wonder you can keep in the path. Many ancient Britons lie buried there doubtless.’

He led her round to the other side, where, feeling his way with his hands, he suddenly left her, appearing a moment after with a light.

‘What place is this?’ she exclaimed.

‘This is the new wood cabin,’ said he.

She could just discern the outline of a little house, not unlike a bathing-machine without wheels.

‘I have kept lights ready here,’ he went on, ‘as I thought you might come any evening, and possibly bring company.’

‘Don’t criticize me for coming alone,’ she exclaimed with sensitive promptness. ‘There are social reasons for what I do of which you know nothing.’

‘Perhaps it is much to my discredit that I don’t know.’

‘Not at all. You are all the better for it. Heaven forbid that I should enlighten you. Well, I see this is the hut. But I am more curious to go to the top of the tower, and make discoveries.’

He brought a little lantern from the cabin, and lighted her up the winding staircase to the temple of that sublime mystery on whose threshold he stood as priest.

The top of the column was quite changed. The tub-shaped space within the parapet, formerly open to the air and sun, was now arched over by a light dome of lath-work covered with felt. But this dome was not fixed. At the line where its base descended to the parapet there were half a dozen iron balls, precisely like cannon-shot, standing loosely in a groove, and on these the dome rested its whole weight. In the side of the dome was a slit, through which the wind blew and the North Star beamed, and towards it the end of the great telescope was directed. This latter magnificent object, with its circles, axes, and handles complete, was securely fixed in the middle of the floor.

‘But you can only see one part of the sky through that slit,’ said she.

The astronomer stretched out his arm, and the whole dome turned horizontally round, running on the balls with a rumble like thunder. Instead of the star Polaris, which had first been peeping in through the slit, there now appeared the countenances of Castor and Pollux. Swithin then manipulated the equatorial, and put it through its capabilities in like manner.

She was enchanted; being rather excitable s............
