say you won’t toss him. I can’t see him, but he’s somewhere close to me.’

‘Very well. I won’t toss him. Open the roof, boy.’

David was not sure that Noah would like this, as he was the ark-master, but he felt that his having said that he would keep the roof shut unless the cow promised, meant that he would open it if she did, and so he lifted the roof about an inch.

At that moment Noah’s head appeared. He was standing on Shem’s head, who was standing on Ham’s head, who was standing on Japheth’s head, who was standing on his mother’s head. They always came out of their room in this way, partly in order to get plenty of practice in case of fire, and partly because they couldn’t be certain that the flood had gone down, and were afraid that if they opened the door, which is the usual way of leaving a room, the water might come in. When Noah had climbed on to the top of the wall, he pulled Shem after him, who pulled Ham, who pulled Japheth, who pulled Mrs. Noah, and there they all stood like a row of sparrows on a telegraph wire, balancing themselves with great, difficulty.

‘Who’s been meddling with my roof?’ asked Noah, in an angry voice. ‘I believe it’s that pin-partridge.’

The pin-partridge trembled so violently at this that he fell off the roof altogether, quite forgetting that he could fly. But the moment he touched the ground, he became a full-sized partridge.

‘No, I didn’t,’ he said. ‘There’s that boy somewhere about, but I can’t see him. He got through the blue door to-night.’

David now knew that he was invisible, but though it had always seemed to him that it must be the most delicious thing in the world to be able to be visible or invisible whenever you chose, he found that it was not quite so jolly to have become invisible without choosing, and not to have the slightest idea how to become visible again. It gave him an empty kind of feeling like when he was hungry long before the proper time.

‘The cats saw me,’ he said, joining in, for he knew if he couldn’t be seen, he could be heard.

‘Of course they did,’ said Noah, ‘because they can see in the dark when everything is invisible. That’s why they saw you. You needn’t think that you’re the only thing that is invisible. I suppose you think it’s grand to be invisible.’

‘When I was a little boy,’ said Ham, ‘I was told that little boys should be seen and not heard. This one is heard and not seen. I call that a very poor imitation of a boy. I dare say he isn’t a real one.’

‘I’ve been quite ordinary up to now,’ said David. ‘It seems to have come on all of a sudden. And I don’t think it’s at all grand to be invisible. I would be visible this minute if I knew how.’

‘I want to get down,’ said Mrs. Noah, swaying backwards and forwards because her stand was broken.

‘You’ll get down whether you want to or not, ma,’ said Shem irritably, ‘if you go swaying about like that. Don’t catch hold of me now. I’ve got quite enough to do with keeping my balance myself.’

‘Why don’t you get down?’ asked David, who wanted to see what would happen next.

‘I haven’t seen the crow fly yet,’ said Noah. ‘We can’t get down till the crow has flown.’

‘What did the crow do?’ asked David.

‘It didn’t. That’s why we’re still here,’ said Japheth.

‘Some people,’ said Noah, ‘want everything explained to them. When the cock crows it shows it’s morning, and when the crow flies it shows it’s night. We can’t get down until.’

‘But what would happen if you did get down?’ said David.

‘Nobody knows,’ said Noah. ‘I knew once, and tied a knot in my handkerchief about it, so that I could remember, but the handkerchief went to the wash, and they took out the knot. So I forgot.’

‘If you tied another knot in another handkerchief, wouldn’t you remember again?’ asked David.

‘No. That would not be the same knot. I should remember something quite different, which I might not like at all. That would never do.’

‘One, two, three,’ said Mrs. Noah, beating time, and they all began to sing:

Most of the animals in the ark joined in, and they sang it to a quantity of different tunes. David found himself singing too, but the only tune he could remember was ‘Rule Britannia,’ which didn’t fit the words very well. By degrees the others stopped singing, and David was left quite alone to finish his verse feeling rather shy, but knowing that he had to finish it whatever happened. When he had done, Noah heaved a deep sigh.

‘That is the loveliest thing I ever heard in my life,’ he said. ‘Are you open to an engagement to sing in the ark every evening? Matinées of course, as well, for which you would have to pay extra.’

This was a very gratifying proposal, but David did not quite understand about the paying.

‘I should have to pay?’ he asked.

‘Why, of course. You’d have to pay a great deal for a voice like that. You mustn’t dream of singing like that for nothing. It would fill the ark.’

‘I should say it would empty it,’ said Mrs. Noah snappishly.

‘I don’t know if I’m rich enough,’ said David, not taking any notice of this rude woman.

‘Go away at once then,’ said Mrs. Noah. ‘I never give to beggars.’

Just then there was a tremendous rattle from the ark, as if somebody was shaking it.

‘It’s the crow,’ shouted Ham. ‘The crow’s just going to fly. Get out of the way, boy.’

The crow forced its way through the other animals, balanced itself for a moment on the edge of the ark, and flew off down the passage, squawking. The moment it left the ark it became ordinary crow-size again, and at the same moment David suddenly saw his one hand still holding up the lid of the ark, and knew that he had become visible. That was a great relief, but he had no time to think about it now, for so many interesting things began happening all at once. The Noah family jumped from the edge of the ark, and the moment their stands touched the ground, they shot up into full-sized human beings, with hats and ulsters on, and large flat faces with two dots for eyes, one dot for a nose, and a line for a mouth. They glided swiftly about on their stands, like people skating, and seemed to be rather bad at guiding themselves, for they kept running into each other with loud wooden crashes, and into the animals that were pouring out of the ark in such numbers that it really was difficult to avoid everybody. Occasionally they were knocked down, and then lay on their backs with their eyes winking very quickly, and their mouths opening and shutting, like fish out of water, till somebody picked them up.

The game-cupboard comes to life

David got behind the cupboard door to be out of the way of the animals and all the other things that came trooping from the shelves. Luckily the nursery passage seemed to have grown much
