What are the instances in the story that show that the character of the ironmaster is different from that of his daughter in many ways?

Edla and her father had different natures. She had more convincing power than the father and was able to persuade the peddler to accept the invitation. We also find that the ironmaster's hospitability was limited to his old comrade. But, the daughter was pained by the plight of the peddler and continued to treat him well even after the truth about his identity was revealed. Again, after finding about the robbery of the crofter's money, while the ironmaster was more concerned with the possibility of the peddler robbing them as well, the daughter is more pained by the betrayal of her trust. We also find that while the father was impulsive and reckless in nature, the daughter's behavior was more mature and controlled.

The ironmaster is impulsive* whereas his daughter is cool, logical, kind and thoughtful. In uncertain light he (iron master) mistakes the stranger as his old regiment comrade. He invites him home and takes care of his feeding, clothing etc. When he sees him in broad day light he calls the man dishonest, demands an explanation and is ready to call in the sheriff. His daughter is more observant. She notices the fear of the stranger and thinks that either he is a thief or a run away prisoner. Inspite of that She is gentle, kind and friendly to him. She treats him nicely even after knowing the mistake in identity.
