Other stones were erected at 5-mile intervals and the west line of the State of Delaware was set up. Soon after this Lord Baltimore died and his death delayed things. Nothing was done for about 10 years, when under a new agreement in 1760, between the then generations of Penns and Baltimores, surveys were started again on this north line, the object being to lay it out so as to hit the 12-mile circle, 81 miles above, determined upon as the northern boundary of Delaware, with New Castle as its center. The surveyors made such a poor job of it, despite several efforts, after 3 years, that Penn and Baltimore in England hired Mason and Dixon, two engineers of note, to go over to America, take charge and do the job. They arrived in 1763, accepted the lower or east and west line across the peninsula as correct, reran the north line and ran the line from the northeast corner of Maryland west, for about 223 miles. This is the generally understood Mason and Dixon’s line. They also ran the north and south line which is the western boundary of Delaware. Five years were occupied in this and not until 1768 was the last stone set, which ended the controversy of nearly a century. By 1857 the site for the lighthouse had been selected and marked and the tower was completed early in 1859, being first lit on August 1, 1859. The total cost was $23,748.96. In 1932 a strip of land 60 feet wide, extending east and west across the site, was deeded to the State of Delaware for roadway purposes and in 1940 about three-fourths of the site was sold including the entire northern wooded half and 2.71 acres of the southern half. The white lighthouse tower now stands 0.3 mile inshore on the coast, the tower being 83 feet above water and the top of the lantern 87 feet above ground. A 25,000-candlepower light flashes white every 3 seconds and is visible 15 miles at sea. (1) (2) _FLORIDA_ AMERICAN SHOAL LIGHTHOUSE Off shore, visible from Overseas Highway at Saddlebunch Keys.
