Sighings and flutterings rose everywhere about them, and overhead the fluffy spires of the tree-tops all bent one way as the winds went foraging across the night. Majestically the scaffolding reared up and towered through the air, while sheets of darkness hung from every line, and trailed across the earth like gigantic sails from some invisible vessel. Loose and enormous they gradually unfolded, then suddenly swung free and dropped with a silent dip and rush. Night swooped down upon the leagues of Jura forest. She spread her tent across the entire range.

The threads were fastened everywhere now, and the uprights all in place. Moths were busy in all directions, showing the way, while bats by the dozen darted like black lightning from corner to corner, making sure that every spar and beam was fixed and steady. So exquisitely woven was the structure that it moved past them overhead without the faintest sound, yet so frail and so elastic that the whirring of the moths sent ripples of quivering movement through the entire framework.

'Hush!' murmured Rogers, 'we're properly inside it now. Don't think of anything in particular. Just follow your wandering minds and wait.' The children lay very close against him. He felt their warmth and the breathing of their little bosoms. All three moved sympathetically within the rhythm of the dusk. The 'inside' of each went floating up into the darkening sky.

The general plan of the scaffolding they clearly made out as they passed among its myriad, mile-long rafters, but the completed temple, of course, they never saw. Black darkness hides that ever. Night's secret mystery lies veiled finally in its innermost chamber, whence it steals forth to enchant the mind of men with its strange bewilderment. But the Twilight Scaffolding they saw clearly enough to make a map of it. For Daddy afterwards drew it from their description, and gave it an entire page in the Wumble Book, Monkey ladling on the colour with her camel's-hair brush as well as she could remember.

It was a page to take the breath away, the big conception blundering clumsily behind the crude reconstruction. Great winds formed the base, winds of brown and blue and purple, piled mountainously upon each other in motionless coils, and so soft that the upright columns of the structure plunged easily and deeply into them. Thus the framework could bend and curve and sway, moving with steady glide across the landscape, yet never collapsing nor losing its exquisite proportions. The forests shored it up, its stays and bastions were the Jura precipices; it rested on the shoulders of the hills. From vineyard, field, and lake vast droves of thick grey shadows trooped in to curtain the lower halls of the colossal edifice, as chamber after chamber disappeared from view and Night clothed the structure from the ground-floors upwards. And far overhead a million tiny scarves, half sunset and half dusk, wove into little ropes that lashed the topmost spars together, dovetailing them neatly, and fastening them at last with whole clusters of bright thin stars.

'Ohhhhh!' breathed Jimbo with a delicious shudder of giddiness. 'Let's climb to the very tip and see all the trains and railway stations in the world!'

'Wait till the moon comes up and puts the silver rivets in,' the leader whispered. 'It'll be safer then. My weight, you know—'

'There she is!' interrupted Monkey with a start, 'and there's no such thing as weight—'

For the moon that instant came up, it seemed with a rush, and the line of distant Alps moved forward, blocked vividly against the silvery curtain that she brought. Her sight ran instantly about the world. Between the trees shot balls of yellowish white, unfolding like ribbon as they rolled. They splashed the rocks and put shining pools in the hollows among the moss. Spangles shone on Monkey's hair and eyes; skins and faces all turned faintly radiant. The lake, like a huge reflector, flashed its light up into the heavens. The moon laid a coating of her ancient and transfiguring paint upon the enormous structure, festooning the entire sky. 'She's put the silver rivets in,' said Jimbo.

'Now we can go,' whispered Rogers, 'only, remember, it's a giddy business, rather.'
