Answer:
The story 'Justin Morgan Had A Horse' is the true story of a school teacher in early America and his little horse that became the founding father of the Morgan Horse breed. I believe the story has Justin Morgan getting a small black horse as payment/trade instead of money. Reluctant at first he soon discovers that this was no ordinary horse. He could out-run, out-pull and out-do every other horse in the town. Its a great story and it was made into a Disney movie.
