Enlarged view of Head of Fly showing Trunk.

3. 'It is called his trunk. The mouth is at the end of it. He is very clever with it. Do you know that he never eats? He only drinks.'

4. 'But I have seen him eating sugar.'

'No; I don't think you have. He has no teeth and no jaws. He can't bite anything. What he does is to wet the sugar with his mouth and melt it, and then suck it up.'

5. 'Well, that is clever! I wonder how he found out how to do it. And I know something else that he is clever at.'

6. 'What is it, Harry?' asked Dora.

'Something you can't do! He can walk on the ceiling.'

'You can't do it either,' said Dora.

'How does he hold on, mother? We can see one up there now! He walks about as if he were on the table.'
