Janthina Photo Images > The Hillsboro Lighthouse is fitted with an original Second Order bivalve Fresnel lens. Manufactured with the encryption: "Phares & Fanaux, Barbier, Benard & Turenne, 82 Rue Curial, Paris", the lens consists of concentric prisms arranged in panels around a central bullseye. The two halves resemble a bivalve shell. A mercury float trough was once used but today a ball bearing system in oil supports the 2 and 1/2 ton lens. Known as the "big diamond' this light shines 28 nautical miles out to sea.

Still on the dock, I observed the lone gull which seemed poised for moment in greeting.
