This story comes from Ernest Seton’s Animal Heroes. In 1862, a ship sailed on the Atlantic Ocean. Thick fog covered the sea, and the engine broke down. The ship was hundreds of kilometres away from land. The captain tried to send a big pigeon for help, but it came back soon. Then he sent the small young pigeon Arny. Arny flew through fog and over the sea for more than four hours. He finally arrived and gave the rescue note to Billy. Billy ran to the office quickly. Help was sent to the ship at last. The captain praised Arny as the most amazing and brave pigeon.
