'Humph!' said the Camel.

'I shouldn't say that again if I were you,' said the Djinn; you
might say it once too often. Bubbles, I want you to work.'

And the Camel said 'Humph!' again; but no sooner had he said it
than he saw his back, that he was so proud of, puffing up and
puffing up into a great big lolloping humph.

'Do you see that?' said the Djinn. 'That's your very own humph
that you've brought upon your very own self by not working.
To-day is Thursday, and you've done no work since Monday, when
the work began. Now you are going to work.'

'How can I,' said the Camel, 'with this humph on my back?'

'That's made a-purpose,' said the Djinn, 'all because you missed
those three days. You will be able to work now for three days
without eating, because you can live on your humph; and don't you
ever say I never did anything for you. Come out of the Desert
and go to the Three, and behave. Humph yourself!'

And the Camel humphed himself, humph and all, and went away to
join the Three. And from that day to this the Camel always wears
a humph (we call it 'hump' now, not to hurt his feelings); but he
has never yet caught up with the three days that he missed at the
beginning of the world, and he has never yet learned how to
behave.
