They lay down, and Cousinenry made a fire. The smoke went up in thin straight lines of blue, melting into the sky. The sun had set half an hour before, and the flush of gold and pink was fading into twilight. The glamour of Bourcelles dropped down upon all three. They ought to have been in bed—hence the particular enjoyment.

'Are you getting excited now?' asked Monkey, nestling in against him.

'Hush!' he said, 'can't you hear it coming?'

'The excitement?' she inquired under her breath.

'No, the Night. Keep soft and silent—if you can.'

'Tell us, please, at once,' both children begged him instantly, for the beauty of the place and hour demanded explanation, and explanation, of course, must be in story or adventure form. The fire crackled faintly; the smell crept out like incense; the lines of smoke coiled upwards, and seemed to draw the tree-stems with them. Indeed they formed a pattern together, big thick trunks marking the uprights at the corners, and wavy smoke lines weaving a delicate structure in between them. It was a kind of growing, moving scaffolding. Saying nothing, Cousin Henry pointed to it with his finger. He traced its general pattern for them in the air.

'That's the Scaffolding of the Night beginning,' he whispered presently, feeling adventure press upon him.

'Oh, I say,' said Jimbo, sitting up, and pretending as usual more comprehension than he actually possessed. But his sister instantly asked, 'What is it—the Scaffolding of the Night? A sort of cathedral, you mean?'

How she divined his thought, and snatched it from his mind always, this nimble-witted child! His germ developed with a bound at once.

'More a palace than a cathedral,' he whispered. 'Night is a palace, and has to be built afresh each time. Twilight rears the scaffolding first, then hangs the Night upon it. Otherwise the darkness would simply fall in lumps, and lie about in pools and blocks, unfinished—a ruin instead of a building. Everything must have a scaffolding first. Look how beautifully it's coming now,' he added, pointing, 'each shadow in its place, and all the lines of grey and black fitting exaccurately together like a skeleton. Have you never noticed it before?'
