They were up bright and early the next morning and, after a plunge in the lake, Bob suggested that they pay a visit to the cave on Mount Katahdin.
“The mountain wouldn’t come to Mahomet, you remember, so Mahomet had to go to the mountain,” he laughed. “Well, the ghost won’t seem to come to us any more so we might as well go to him.”
“But why do you think he’s there?” Jack asked.
“I don’t, but we may get a clue. Somehow I can’t help thinking that the fellow they call Jim the Penman is in some way mixed up in the ghost business.”
“Well, it’ll get rid of the day anyhow,” Jack said, and Kernertok agreed that it was a good plan.
They started immediately after breakfast, telling the Sleepers that they were going to the dam and might not be back until night. The wind was blowing strong down the lake and Kernertok and Jack made the light canoe almost fly through the water.
“Haven’t seen anything more of those fellows have you?” Bob asked the old dam tender, who met them as they landed.
“No, but I seen a light up on the mountain, ’bout ten o’clock las’ night,” he told them.
“Did it flash as though someone was signaling?” Bob asked excitedly.
