CHAPTER XII.
A MOUNTAIN MYSTERY "Perhaps the postscript is to tell us that it is all a mistake and that we do not have to leave," suggested Emma.
"Listen!" commanded Hippy, then began to read: "'Do not follow the trail you are on, on your way to Thompson's.

Strike due north for half a mile and you will come up with a wagon trail, broader and safer, because you can see a long way on either side through the thin forest.

Keep the broad trail for fifteen miles, take third left and second right, which will take you to Thompson's.

You're all right, but be vigilant.

The above warning means what it says.'" "Is there a name signed to the postscript ?" asked Miss Briggs.
Hippy shook his head.
"I know who wrote that postscript," spoke up Miss Dean.
