As it turned, it disclosed a subterranean passage.
"Ah!" exclaimed Roland, "this is the way my spectre went." He entered the yawning cavern, followed by Sir John.

They traversed the same path that Morgan took when he returned to give an account of his expedition.

At the end of the passage they came upon an iron gate opening into the mortuary vaults.

Roland shook the gate, which yielded to his touch.

They crossed this subterranean cemetery, and came to a second gate; like the first, it was open.
