‘Look, Stephen—the courage of these old fellows! They’re all twisted and crippled; it hurts me to see them, yet they go on patiently doing their bit—have you ever thought about the enormous courage of trees? I have, and it seems to me amazing. The Lord dumps them down and they’ve just got to stick it, no matter what happens—that must need some courage!’ And one day he said: ‘Don’t think me quite mad, but if we survive death then the trees will survive it; there must be some sort of a forest heaven for all the faithful—the faithful of trees. I expect they take their birds along with them; why not? “And in death they were not divided.” ’ Then he laughed, but she saw that his eyes were quite grave, so she asked him:

‘Do you believe in God, Martin?’

And he answered: ‘Yes, because of His trees. Don’t you?’

‘I’m not sure—’

‘Oh, my poor, blind Stephen! Look again, go on looking until you do believe.’

They discussed many things quite simply together, for between these two was no vestige of shyness. His youth met hers and walked hand in hand with it, so that she knew how utterly lonely her own youth had been before the coming of Martin.

She said: ‘You’re the only real friend I’ve ever had, except Father—our friendship’s so wonderful, somehow—we’re like brothers, we enjoy all the same sort of things.’

He nodded: ‘I know, a wonderful friendship.’

The hills must let Stephen tell him their secrets, the secrets of bypaths most cunningly hidden; the secrets of small, unsuspected green hollows; the secrets of ferns that live only by hiding. She might even reveal the secrets of birds, and show him the playground of shy, spring cuckoos.

‘They fly quite low up here, one can see them; last year a couple flew right past me, calling. If you were not going away so soon, Martin, we’d come later on—I’d love you to see them.’
