Unlucky Stumbling.
Reading edition
When Mungo Park took his leave of Sir Walter Scott, prior to his second and fatal expedition to Africa, his horse stumbled on crossing a ditch which separated the moor from the road. "I am afraid," said Scott, "this is a bad omen." Park smilingly answered: "Omens follow them who look to them," and, striking spur into his horse, he galloped off. Scott never saw him again.
