Even though the chart was drawn during the British Period, it shows the importance of the harbors and rivers that come together at Amelia Island. The map was published by Thomas Jefferys in his ""Plan of Amelia Island in Florida"" in 1770 and later by Faden in ""American Atlas"" in 1781. This area reached its main importance in the Second Spanish Period as an entrance of imported slaves into the United States after it abolished the slave trade in 1808. The chart was dedicated to John, Earl of Egmont who owned an indigo plantation on the north end of Amelia Island. It was visited in 1773-1775 by William Bartram who wrote a description of the area. The town Nouvelle Ville on Isle Amelia later became the Old Town when Fernandina was established.
