'Waiting is one of those things that you can do as well asleep as awake, or even better,' said the parrot.

'Forty winks will do us all the good in the world.' He put his head under his wing where he sat on the binnacle.
'May I turn in alongside you, sir ?' Max asked.

'I shan't feel the dreadful loneliness so much then.' So Philip and Max curled up together on the deck, warmly covered with the spare flags of all nations, and the forty winks lasted for the space of a good night's rest--about ten hours, in fact.

So ten hours' waiting was got through quite easily.

But there was more waiting to do after they woke up, and that was not so easy.
