About This Book

The text presents a technical and narrative account of the planning, quarrying, and multi‑season construction of a remote offshore lighthouse, including topographic surveys, establishment of workyards and quarries, erection and loss of temporary barracks, and methods for laying foundations and dressing stone. It explains tower design principles and details operations, equipment, personnel arrangements, and weather‑related hazards encountered during successive seasons. A substantial technical section discusses advances in lighthouse illumination, especially the dioptric (Fresnel) system, and appendices supply tables, experimental notes, costings, charts, and keeper instructions.
