They found the others waiting on the smooth layer of soft purple air that spread just below the level of the tree-tops. The crests themselves tossed wildly in the wind, but at a depth of a few feet there was peace and stillness, and upon this platform the band was grouped. 'The stars are caught in the branches to-night,' a sensitive walker on the ground might have exclaimed. The spires rose about them like little garden trees of a few years' growth, and between them ran lanes and intricate, winding thoroughfares Mother saw long, dark things like thick bodies of snakes converging down these passage-ways, filling them, all running towards the centre where the group had established itself. There were lines of dotted lights along them. They did not move with the waving of the tree-tops. They looked uncommonly familiar. 'The trains,' Jimbo was crying. He darted to and fro, superintending the embarking of the passengers. All the sidings of the sky were full of Starlight Expresses. The loading-up was so quickly accomplished that Mother hardly realised what was happening. Everybody carried sacks overflowing with dripping gold and bursting at the seams. As each train filled, it shot away across the starry heavens; for everyone had been to the Cave and gathered their material even before she reached the scene of action. And with every train went a _mecanicien_ and a _conducteur_ created by Jimbo's vivid and believing thought; a Sweep, a Lamplighter, and a Head Gardener went, too, for the children's thinking multiplied these, too, according to their needs. They realised the meaning of these Sprites so clearly now--their duties, appearance, laws of behaviour, and the rest-that their awakened imaginations thought them instantly into existence, as many as were necessary. Train after train, each with its full complement of passengers, flashed forth across that summer sky, till the people in the Observatories must have thought they had miscalculated strangely and the Earth was passing amid the showering Leonids before her appointed time. 'Where would you like to go first?' Mother heard her friend ask softly. 'It's not possible to follow all the trains at once, you know.' 'So I see,' she gasped. 'I'll just sit still a moment, and think.' The size and freedom of existence, as she now saw it, suddenly overwhelmed her. Accustomed too long to narrow channels, she found space without railings and notice-boards bewildering. She had never dreamed before that thinking can open the gates to heaven and bring the Milky Way down into the heart. She had merely knitted stockings. She had been practical. At last the key to her husband's being was in her hand. That key at the same time opened a door through him, into her own. Hitherto she had merely criticised. Oh dear! Criticism, when she might have created!
