“Well, if you want to do it that way, I’m willing,” assented Blake. “Probably all we’ll find, though, is some tramp sleeping in the shack. Very well, we’ll lay the ghost to-morrow.”

“And we won’t tell the girls about it until we solve the mystery,” added Phil.

“That’s what,” added Jack.

But the next day it rained, so they postponed their ghost-hunting expedition. There was nothing much to do, though, so in the afternoon the boys donned old garments, and went over to the Point, through the drizzle, for some supplies, shopping for the girls at the same time.

Natalie’s ankle was better, it was reported, and the following day she could hobble about a bit.

“But I’m going to sit still and do bead work for a while,” she said when the boys came to call, and she showed where, on a hand loom, she was working a Camp Fire device for a bead head-band—her emblem of a pine tree being made in a conventional design. The other girls were also busy.

“Then you’re not going to the mill again?” asked Jack.

“No, indeed!”

Late that afternoon, giving out some excuse to the girls not to see them that evening, the three chums, having packed a basket of lunch, with some candles for light, some bags to use for cushions, set off for the old mill. They intended to pass the night there to prove or disprove that any one—whether of this earth or some other—was in the ancient structure.
