"I am glad they do not," Cora said, "for I want to do some exploring, and if the boys came along they would be sure to have other plans for us. Now, Hazel, run in there. That is Fern Island."

"Oh, there's a canoe!" exclaimed Belle. "See! and a girl is paddling. What a queer looking girl!"

"Isn't she!" agreed Bess. "Why she has on a man's hat!"

"She sees that we are watching her. Look how she is hurrying off," remarked Cora. "I wonder how far this cove goes in?"

"We had better not try to find out," cautioned Belle. "I think we have had enough of happenings around here. This is where the boy's boat was stolen from; isn't it?"

"No, it was over there, but I guess we will put in at the front of the island, as there is no telling how deep the cove is," said Cora. "But see that girl go! Why she's actually gone! Where can she have disappeared to?"

"This ought to be called the 'disappearing' land," suggested Hazel. "I was sure that little canoe was directly in front of us, but now it is out of sight."

"Maybe that is the 'Haunt Girl of Fern Island,'" ventured Cora with a laugh. "I got a pretty good look at her, and I am willing to say she looked neither like a summer girl nor a winter girl—that is, one who might live here the year around. But just what sort of girl she might be I shouldn't like to speculate. Her hair got loose as she hurried, and she reminded me of some wild water bird."

"Be careful getting out," Belle cautioned Bess. "This new boat is new to slipperiness."

"Oh, I will get hold of a tree branch," Bess replied. "Then, if the boat drifts out, I can swing to safety."
