I lived first in a little house, And lived there very well;
I thought the world was small and round,
And made of pale blue shell.

I lived next in a little nest,
Nor needed any other;
I thought the world was made of straw,
And brooded by my mother.

One day I fluttered from the nest
To see what I could find.
I said, “The world is made of leaves;
I have been very blind.”

At length I flew beyond the tree,
Quite fit for grown-up labours.
I don’t know how the world is made,
And neither do my neighbours!
