Excerpt: "This tale, reader—if you read it through—will give you some insight into the condition, value, and vicissitudes of the light-vessels, or floating lighthouses, which guard the shores of this kingdom, and mark the dangerous shoals lying off some of our harbours and roadsteads. It will also convey to you—if you don't skip—a general idea of the life and adventures of some of the men who have manned these interesting and curious craft in time past, as well as give you some account of the sayings and doings of several other personages more or less connected with our coasts. May you read it with pleasure and profit, and—"may your shadow never be less."
