The Winter Pony is about a horse named James Pigg. The story started when he was a cute, white colt, dancing in the field with his mother, the stallion, and the rest of the herd. When rough men captured the stallion and James Pigg, he was pushed into cruel work. He was broken very roughly. The men would whip him until they got bored. One man hit him over and over on his collar bone with a glass bottle. James Pigg had a scar there for the rest of his life. When he was broken, he was forced to move heavy logs and other things. After he completed many years of tough work, he was put up for sale in a carnival with other worked horses. He was bought by a gentle man and boy. They bought 19 other white ponies, including the stallion from James Pigg's herd. He and the other horses were put on a ship and treated with love and care. He was named James Pigg on the ship. When they reached their destiny, he learned that they were going to the South Pole. On the way there, many horses died, and some were killed because they were in pain, too old, too slow, or untamed. Which horses survived, which didn't?
