A Horse and a Dog
Once upon a time there was a horse whose name was Reginald. Every morning he was delivering dairy products. On his way by the post office he usually met his friend Blackie, who was a little black dog.
Reginald didn’t want to be a milkman’s horse. He wanted to be a racehorse and win the Derby. And Blackie had rather short legs. He wanted to be able to run very fast, like a hound.
One afternoon they were sitting in Reginald’s stable. Suddenly Blackie had an idea. “Why do we not eat coal?” he said. “Trains eat coal and run fast.”
The friends thought about this for a long time, and at last Reginald said: “Let’s try it.” So they went down to the room where coal was. They were going to take some coal, when Mrs Marry, the landlady, came in.
“What! You are stealing my coal!” she began to cry, and she picked up a piece of coal and threw it them. Reginald and Blackie ran away. They never run so fast in their lives before. At that very moment the Mayor of the town was looking out of the window. “Oh, that horse can run fast. I’m sure it can win the Derby. And look at the dog! It’s a real hound. I’ll give them each a medal.” And he did.
