"Phil," called Lillian, "I thought I heard something. Did you? Listen once more. There, did you hear that?"

Phil listened. "Not a sound, Airy Fairy Lillian. It must have been your fancy."

But Lillian was not convinced. Several times she believed she heard the noise again. However, she did not mention it.

As the girls came out of the woods to a little clearing Phil, who was in the lead, ran forward. "Madge, Eleanor," she called, "come here, quick! I am sure this must be a regular, old-time log cabin."

Before them the girls saw an old cabin that looked as though it had been empty for a quarter of a century. It was strongly built of logs, and the chinks between the logs were filled with mud that had hardened like plaster. There were no windows in the cabin, except in the eaves. The heavy door was half open, but it had an old-fashioned wooden latch on the outside.

"The old cabin looks rather creepy, doesn't it, Madge?" asked Eleanor. "It is built more securely than our cabins farther down south, too. This place seems more like a prison."

"It looks interesting. Let's go in to see it." Phil suggested.

The cabin stood in front of a stream of clear water. Close around it grew a number of dark old cedar trees.

Phil and Madge shoved open the heavy door. Inside, the one large room looked gray and dark, as the only light came from the two small windows so far overhead.

"I would rather not go in, Madge," protested Eleanor, hesitating on the threshold after Lillian had followed the other two girls inside.
