I shall not remain alone with them; I shall try to scale the castle wall farther than I have yet attempted I shall take some of the gold with me, lest I want it later. I may find a way from this dreadful place.

At least God's mercy is better than that of these monsters, and the precipice is steep and high. At its foot man may sleep - as a man. Goodbye, all! Mina!
