an open space a short distance from the tree that
held Jane. She was straining every muscle to get a glimpse of them.

"Some one has been along here since I passed," declared George. "I found
a footprint in the moss over there, and it was a woman's."

"So did we find the same thing," answered Larry. "There's something
queer about this whole island. I feel spooky all the time. Did you hear
any one?"

"No."

"Well, I did. Some one threw a stone at me. It dropped right at my
feet."

Jane giggled softly. Harriet had been playing tricks on them. She
wondered where Harriet was. Jane would have given the signal, but dared
not do so. In the first place she was not sure that she could imitate a
crow so as to deceive a person, and in the second place the boys were
too close to her to run any chances.

"They are here, all right, boys," cried George. "I was certain of it all
the time."

"It may be spooks," answered Larry Goheen.

"Well, just let them come out. I guess we can take care of any spooks
that we shall find on this island. But we must get busy again. It will
soon be dark. Spread out, fellows. I'll tell you what we'll do. Taking
that tree there for a centre"--waving toward the tree occupied by Crazy
Jane McCarthy--"we will circle about, making the circle larger each time
we start out."

"Wait. I'll climb the tree and take a look around," interjected Sam. He
started for the tree. His hands had grasped it ere Jane realized that
hers was the tree meant. For once in her life Crazy Jane McCarthy was at
a loss to proceed. She did not know what to do. But George unknowingly
came to her rescue.

"Never mind the tree. It's too low. You can't get high enough to look
over the tops of the bushes. You come along as I suggested."

"How ever am I going to get out of this?" muttered Jane. "Won't Harriet
be cross when she finds I've quit my post and gone out on my own
responsibility?" Her further reflections were interrupted by a loud
"caw, caw, caw!"

"What's that?" cried Larry in alarm.

"It's a crow, you tenderfoot," jeered George. "Didn't you ever hear one
before?"

"Harriet!" exclaimed Jane under her breath. "She has discovered where
the boys are. She's giving me warning and I dare not answer her. What
shall I do?"

"Yes, I have heard crows, but I never heard a crow with a voice like
that," answered Larry. "I'll bet it's no more crow than I am."

Once more the crow cawed. This time the bird's voice sounded much
