eral times to Aaron
Dennison and his strangely fenced-in property. But although many
suggestions were brought out in the discussion, none of them were
fully accepted as correct.

Frank and Will remained almost silent, and let the other two do most
of the talking. If the opinion of the former was requested now and
then he gave it off-hand, but neither Bluff nor Jerry found much to
encourage him in the information thus gleaned.

Frank never once lost the dim trail on the way home. He had no
difficulty whatever in following his course, because by now he was
getting familiar with it; and since several of them had tramped over
the ground there were many signs to be found that had not been there
the first time.

A tired lot of boys it was that joyfully greeted the sight of the
cabin on the Point late that afternoon.

"But after all's said and done," declared Bluff, "we've had a bully
day!"

"And I've added considerable to my stock of pictures, if only these
turn out O. K.," added Will, his mind, as usual, running to the one

Later on he and Frank happened to be left alone. Bluff had gone down

little print that displayed the building inside the high board fence.
"And right now I'm wondering if we hadn't better keep this out of
their sight until we get home."

"I take it to mean you're afraid of Jerry and Bluff?" queried Will.
"They are both of them determined fellows, once they take the bit in
their teeth. That face might tantalize Jerry so much that he'd give
in."

"Of course it's struck you, Will, that there are what seem to be bars
across that window, though neither of us remembers seeing them at the
time. For that matter we failed to glimpse the white face or the
waving handkerchief."

"Frank, you've been thinking this business over," observed Will,
soberly; "please tell me what decision you've come to. I've kept my
