Classic Poem

We saw a raven very high above us.
It called out, and the dome of the sky
Seemed to echo the sound.
It called again and again as it flew onwards,
And the mountains gave back the sound
Seeming as if from their centre—
A musical bell-like answering
To the bird's hoarse voice.
We heard both the call of the bird
And the echo
After we could see him no longer.
