Describe the catechist. How is it he can guide David to his destination? What happened in the end? From chapters 13-16

David met another catechist, Henderland, who was a member of the Edinburgh Society for Propagating Christian Knowledge. Being from the south, the catechist and David got along well and David was pleased to hear his own language. Henderland was kind enough to bring David back to his dwelling to sleep and eat. David was surprised by the hypocrisy of the catechist, rushing back to his home for his snuff but preaching to David about humility before God. Still, David found himself deeply moved and tried to think less highly of himself. The next morning, Henderland arranged for a man who was crossing the Linnhe Loch to Appin to bring David across, thus saving him from two ferry rides.
