“Mr. Sleeper this is my brother, Jack,” Bob introduced him as he came up.

“Mr. Sleeper was just telling me that he wants to go up to the camp,” he explained.

“Yes,” the man added. “You see I engaged board during the winter and I do not understand why there is no boat to meet us. The letter stated that a motor boat made regular trips to the dam.”

The two boys looked at each other uncertain what to say for fully a minute then Bob, realizing that the situation was becoming awkward, said:

“Well, you see, there are no boarders there now except us and I guess they have not been running the boat lately.”

“But I understood from the letter that the camp was filled all the time.”

“It isn’t now: in fact there’s no one at all there except my brother and I.”

“But why? I don’t understand it,” he insisted.

“Ghosts,” Bob said with a smile.

“Ghosts!”
