“The walking of girls’ vulnerable feet,
The heart in its own endless silence kneeling.”

“I can exchange opinion with any neighbouring mind,
I have as healthy flesh and blood as any rhymer’s had,
But O! my Heart could bear no more when the upland caught the wind;
I ran, I ran, from my love’s side because my Heart went mad.”

When all but dead of thirst,
Hardly dared to wet his mouth
Imagining, moon-accursed,
That another mouthful
And his beating heart would burst.”
