(AP) -- SULLIVANS ISLAND, S.C. (AP) -- A formal dedication is being held this weekend for a new exhibit on the international slave trade at Fort Moultrie on South Carolina 's Sullivans Island .
During the days of the slave trade, hundreds of thousands of slaves who came to the United States passed by the island and some were quarantined there.
The exhibit, "African Passages," opened last month and is being formally dedicated by the National Park Service at 3 p.m. Sunday.
South Carolina poet laureate Marjorie Heath Wentworth will also be on hand to sign copies of her new children's book "Shackles," which tells the story of a couple of young boys who dig up a set of slave shackles on the island.
