Off Eleuthera's northern tip lies St. George's Cay, the site of Spanish Wells. The Spaniards used this as a safe harbor during the 17th century while they transferred their riches from the New World to the Old. Residents—the few surnames go back generations—live on the island's eastern end in clapboard houses that look as if they've been transported from a New England fishing village. Descendants of the Eleutheran Adventurers continue to sail these waters and bring back to shore fish and lobster (most of the Bahamas' langoustes are caught here), which are prepared and boxed for export in a factory at the dock. So lucrative is the trade in crawfish, the local term for Bahamian lobsters, that the 1,500 inhabitants may be the most prosperous Out Islanders.
