How does the treatment of Black Beauty's master in Chapter 1, My Early Home, show the difference between kind treatment and cruelty provide an example from the text?

Breaking in, as Black Beauty explains, is to train a horse to bear a saddle and rider and respond to the rider’s commands. On top of all that, the horse has to learn how to handle having a cart or carriage trailing behind it, and how to handle all the equipment that comes with it. The worst part for Black Beauty is the bit, which goes right over the horse’s tongue and causes, as he points out, long-lasting discomfort. But with the kind words and encouragement of his trainer, Black Beauty is able to become accustomed to even that hardship.

After Black Beauty’s progress in this process, his trainer sends him to a neighbor’s meadow for further training. There, he witnesses for the first time a train, and though initially frightened by it, he soon becomes quite used to the noisy, flashing contraption. This proved to be of huge benefit to Black Beauty, as he was more used to railway stations and other features of city life than other horses. All in all, Black Beauty passes the breaking in process quite well; he attributes his success to the gentle and wise nurturing of his master.
