Read the poem and answer the question that follows.

I saw three witches
That bowed like barley,
And flew on their brooms in the sky,
They soared on a cloud,
Above with a sound,
Stood black in the silver as they did fly.

I saw three witches
That teased little sparrows,
In cages they carried along,
Till a hawk from above,
Swooped down like an arrow,
And freed all the sparrows, correcting the wrong.

I saw three witches
That sailed on a boat,
All with smiles that were mean,
Till a bank of green trees came
They hid their faces with ease,
Though I heard them laughing, they were not seen.

I saw three witches
Asleep in a valley,
Their heads like pebbles,
And then the moon shone so bright
In the valley that night,
Turned them to bushes, so they wouldn't trouble.
