About 1770 that rare naturalist and botanist, William Bartram, landed here and traversed the island, being set across to Amelia Island (Fernandina) by a hunter whom he found living here. He was then at the commencement of his romantic journeyings among the Seminole Indians up the St. John's River, then running through a wilderness. Another fortification, Fort St. Andrew, situated on the north-west point of the island, may still be traced by the ruins of its walls. A well is known there into which, it is said, the English threw ten thousand pounds in silver upon the approach of the Spaniards. In this way, by vestiges of foundation-walls, are indicated the various settlements of the island--mansions and cabins that have passed away, leaving no other sign but these sad memorials of the past. At the conclusion of peace, and immediately after the close of the Revolution, the southern portion of Cumberland Island came into the possession of General Nathaniel Greene. It is said by some to have been presented to him by the State of Georgia in connection with the beautiful estate of Mulberry Grove, where he removed with his family and took up his residence. His lamentably premature death prevented the consummation of his design to build here a retreat in which to spend the hot summer months. He had resided but a year upon his estate of Mulberry Grove, and had hardly commenced to beautify and adorn this chosen residence of his maturer years, when a sun-stroke cut him down in the prime of his life. The general had selected the site of the mansion to be built at Dungeness, and had planned the grounds, laid out a garden--which subsequently became famous for its tropical products and roses--and had lined through the forests of live-oak those avenues which have since grown to such magnificent proportions. As has been related, he did not live to see the completion of his work, but died almost at its very inception. In 1786 the year of his death, the foundation-walls were laid of the mansion-home of Dungeness, but the building was not finished till 1803. Even after it had been occupied for years, and during the sixty years and more it was used as a residence by the descendants of General Greene, there remained a few unfinished rooms. A tradition in the family to the effect that some great misfortune would befall it if the building were finished prevented, it is said, its completion. In the early part of the present century it was the most elegant residence on the coast.
