Lesson 12 Goodbye and good luck
Our neighbor, Captain Charles Alison, will sail from Portsmouth tomorrow. We'll meet him at the harbour early in the morning. He will be in his small boat—Topsail. Topsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we'll have plenty of time. We'll see his boat and then we'll say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic.
