Down the rushy glen,
We daren’t go a-hunting
For fear of little men.”

A world without a meaning, and had room,
Alone amid magnificence and doom,
To build himself an airy monument”

Else would I tear the cave where Echo lies
And make her airy tongue more hoarse than mine
With repetition of “My Romeo!””
