And pray'd him her old life to spare, not slay.
"I will, by Pan, I will," the wolf replied,
"If in thy next three words thou hast not lied."
"Well: first then," said she, "would we had not met!"
Next that a blind wolf had my path beset!
And third, and last," she added, "go for ever:
I trust from this day forth to meet thee never!"
