What are two experiences of Beauty's life that teach him lessons in Black Beauty?
Two experiences that teach Black Beauty lessons are his experiences of witnessing the consequences after a fox hunt, and his fortnight spent at a neighbor's meadow.
1. In Chapter 2 Darkie (what Black Beauty is first called) learns the dangers of the fox hunt. One day, his mother tells him about how the dogs frantically chase the fox, and the men ride recklessly after them, often hurting themselves and tearing up the fields.
While they watch a hunt, a horse falls and a young man lies on the ground. When the other men rush to him and pick him up, his head falls back and his arms hang limply as he is carried to the master's house.
The horse's leg is broken and he must be shot. Darkie's mother tells him that she knew Rob Roy; so, after this death, the mare never goes to his part of the field again. Some days later, there is a funeral for George Gordon, the pride of Squire Gordon's family. "What they did with Rob Roy I never knew. But 'twas all for one little hare."
2. In Chapter 3 when Darkie is four years old and fully grown, he is sent to spend a couple of weeks in a meadow that has one side of it near railroad tracks. While there, he enjoys the grass and the company of the other animals, but when he first hears the train, Darkie is terrified, and in his fear he gallops to the other side of the meadow. However, he notices that the cows do not budge when the train roars past the meadow, so Darkie eventually calms down and ignores the noise, too.
This training serves the black horse well:
Since then I have seen many horses much alarmed and restive at the sight or sound of a steam engine. But thanks to my good master's care, I am as fearless at railway stations as in my own stable.
