d door, Tom and Dick joined
Sam, and in the darkness made their way to the rear of the room in
which they had held Cuffer and Shelley prisoners. In a minute more they
were outside, under the trees at the rear of the old mill.

"Which way did they go?"

Tom asked the question, but nobody could answer it. The moon had now
gone under some clouds and it was so dark they could scarcely see ten
feet in any direction.

"Perhaps they took to the river again," suggested Sam.

"It is not likely," answered his big brother. "But we can take a look."

They ran around to where the men had landed. Their boat was still in
its place, tied to a tree.

"Listen!" cried Sam. "Somebody is shouting, and there is a light."

"It is Jack Ness," said Tom.

The boys set up an answering shout, and soon a boat came up to the
shore. It contained the hired man and the two Ditwolds. They had a
lantern with them and also an old-fashioned single-barrel shotgun.

The situation was quickly explained, and then the party of six began a

"We may as well give up," said Dick, at last. "They have gotten away
and that is all there is to it."

The boys were completely tired out when they got home. Their uncle and
aunt were much worried over their prolonged absence and overjoyed to
see them return unharmed.

"I was so afraid one of you might get shot or something," said Mrs.
Rover. "Some of those chickens thieves are desperate characters."

"Those men were more than chicken thieves," answered Dick. And he told
his uncle and aunt of the conversation overheard at the old mill.

"It is a great pity that they got away," said Randolph Rover.

"What do you imagine they are after. Uncle Randolph?" questioned Sam.

"I do not know, excepting it may be some mining stocks or a deed to
some property. Perhaps your father will be able to explain it when he
gets back."

The authorities were notified, but they failed to apprehend the men. It
was learned that the boat they had used had been stolen from a point
near Oak Run, and the craft was returned to its owner. That they had
used the old mill for a stopping place was evidenced by the remains of
numerous meals found there. The boys made a careful search of the
premises, but brought nothing to light which was of use to them.

"I wish father was home--or we knew ho
