“Yes, like a big, strong boy, she has been going up those hills daily. She didn’t say just what she was looking for, did she?” asked Julia.

“Zinc mine, wasn’t it?” suggested Louise.

“Something about ores,” added Julia. “You know her Aunt Carrie said Mr. Ramsdell used to be a government geologist.”

An hour later they were in the lake, trying out their contest stunts. Corene did not succeed in inducing Peg to accompany them, as the excitement around the log cabin was still in evidence. Even the officer sort of “hung ’round,” to “keep an eye on things,” and when Corene made her flying trip up there she found Peg so busy that good sense forbade the Scout delaying her.

The swim over, next came the delivery of all those homemade messages. Hither and thither scouted the Scouts, until lunch time was pointed out by the faithful little sun dial, and that was not a point to be overlooked.

Only two days remained now until the week would be closed. Then would come the excitement of breaking camp.

It was all delightfully thrilling. In spite of the natural regret that accompanied this sacrifice, there was also that joy of satisfaction that always comes with the doing of a real heroic act. Every girl-Bobbie of them felt it her own personal privilege to invite those city youngsters out to Lake Hocomo, and likewise each felt the elation of “doing a big thing.”

“I wonder when Peg will come back for her valuables?” mused Grace. They were “slicking” up the grounds for the day’s inspection—someone always came by and looked in on pleasant mornings.
