“Visitors?”
“Yes; they come occasionally. The cave is quite a curiosity in its way, and once in a while somebody takes it into his head to explore it. That was the case to-day, and so we let the water on.”
“Let the water on?”
“Yes; the existence of this room is a secret, known only to us. There is an underground stream which empties over the rocks by the sea, and we have a sort of dam or gate by which we can turn the water over the door here. It’s a very simple arrangement, but it prevents discovery.”
“Discovery of this room, you mean? Why do you wish to keep its existence a secret?”
“Well, there’s a very good reason just now—you’re here.”
“Yes, I know; but at other times?”
“That I mustn’t tell you.”
“No? Well, it is very strange. I should think you would have to keep a pretty sharp lookout for visitors.”
“Yes, we do,” replied Snags, with a smile.
