New Jersey's Barnegat Lighthouse: Each lighthouse is given a different pattern, which is sometimes enhanced by different colors. The designs are not for aesthetic purposes, but because the towers are used as navigational aides during the day. In fact, in this role, they serve as daymarkers. When people off the coast see a lighthouse, they know which one it is by its markings, and that's the way they know where they are. Perhaps this fisherman used the Barnegat Light as a daymarker during his many returns from Neptune's domain. Greenwood Cemetery.
