It was this vast collective consciousness that had awakened him. He had somehow or other taken on, through Joan, certain conditions of the great Bird-mind. It was marvellous, yet at the time seemed natural. He recalled the strange sentences: all descriptive of a bird's mentality, put into words, of course, by his own brain. The movement of objects was merely their new appearance, seen from above in rapid passage, all speaking, telling something, reporting to the rushing bird the conditions of the surface where they lay. And those at the point of lowest approach in the curve of flight appeared to 'jump.' The sense of rhythm, moreover, was the outstanding characteristic of feathered life—in song, in movement, in beat of wing, in swinging habits of the larger kind when migration regularly sets in and there is known that 'mighty breath which, in a powerful language, felt not heard, instructs the fowls of heaven.' He had responded somehow to the world of greater rhythms in which all airy life existed, and compared with which human existence seemed disjointed, disconnected, incomplete in rhythm.

'Air,' he remembered from one of the ridiculous Primers, 'is the highest perception we have, yet we need not be in the air to get this view. We have placed the Heaven within us up there, because it was, physically, our highest place to set it in.'

'Listen! and you'll feel it all over you,' Joan's voice reached him. 'I often come here in the dawn. I know things here.'

By 'listen' she meant apparently 'receive,' for no sound was audible except the hum of London town still sleeping heavily.

'So this is how you learn things! From the air?'

'I don't learn anything—in that sense,' she murmured quickly. 'It's in me. It just flies out—I see it.'

'Ah!' He caught a feather and understood.

'Especially when I go like this! Look, Daddy!' And she darted from his side and began on tiptoe a movement, half dance, half flight, between the crowding chimney-stacks. She vanished and reappeared. He heard no sound. The shadows clothed her, now close, now spread out, like wings whose motion just escaped the measuring eye. And the dance was revealing in someway he could not analyse. She seemed to bring the dawn up. The ugly roof turned garden, the chimneys shaded off into trees, as though her little dance flashed aspiration into rigid bricks. She interpreted the flight of darkness, the awakening of wings, the silent rush of dawn. No modern dancer, interpreting Chopin, Schumann, could have given a deeper, truer revelation. She uttered in her movements a language that she read, but a language for the majority at present undecipherable. Action and gesture interpreted the inarticulate.

She expressed, he was aware, the return to consciousness of the birds; but at the same time she expressed a new air-born consciousness that was stealing out of the skies upon a yet sleeping world.

'By doing it, I understand it,' she laughed softly, but no whit breathless, as she floated back to his side. 'But I can't tell it in words till long afterwards.'
