There are many examples of foreshadowing throughout the story. Name one

When the captain of the ship - Whitney - tells Rainsford that the name of the island is "Ship-Trap" island, he suggests that it is a place to be feared and that when ships move too close to the island, they may be in danger. The trap idea suggests that Rainsford, once he falls off the ship, will be "trapped" although because of his quick wit, the trap does not end his life.
