“By George, Merry!” whispered Bart, “Worthington may have been right when he told you he saw some one beyond those bowlders.”

“He was.”

“Then we have been followed! We have been spied upon!”

“No question about it.”

“Who did it?”

“That’s for us to find out.”

Together they searched for the man at whom Frank had fired in the darkness. They found nothing of him. From the tent little Abe began calling to them. Then Worthington came hurrying and panting through the darkness seeking them.

“They have gone!” declared the man wildly. “They were here! In my sleep I felt them! In my sleep I saw them!”

“We must have a light, Hodge,” said Frank. “Bring the lantern.”

Bart rushed back to the tent and brought the lantern. With it Frank began examining the ground.
