Follow Thomas Knox through a day of work at Boston Light. As we learn about some of the daily tasks and responsibilities of a colonial lighthouse keeper, Knox’s reminiscences tell the reader the history of Boston Light, while we also learn what some of his daily responsibilities might have been. Knox, and other lighthouse keepers like him, maintained the lighthouse, lit its huge lanterns nightly, and monitored the weather. When a storm arose, Knox often risked his life to save sailors whose boats crashed on the rocks beyond the lighthouse.
