Some areas were very dangerous for ships, so lighthouses* were built in these places. At night, people on ships knew they had to be careful when they saw the light on the top of a lighthouse. The people who took care of lighthouses were called lighthouse keepers, and their job was very important. In 1853, a 14-year-old girl named Abbie Burgess moved to an island in Maine with her family. No other people lived on the island, and Abbie's father was the lighthouse keeper. Abbie helped her father in the lighthouse. She learned how to clean the lights in the lighthouse and do many other things. The lights had to shine* brightly until morning. Just before winter in 1856, Abbie's father had to leave the island to buy food. He had to go 25 miles by boat to get to the nearest town. He told Abbie to take care of their family and the lighthouse. After he left, a big storm came, and it was the biggest storm in 100 years. It rained and snowed for four weeks, so Abbie's father could not return to the island. Abbie took care of the lighthouse by herself for one month. Finally, Abbie's father came back. He was very happy because his family was safe. Abbie did a great job. Her work saved many people's lives. Abbie became the assistant* lighthouse keeper in 1862.
