A short time afterwards Hugh's keen eyes made a discovery.

"I think the wall you mentioned lies over yonder where all that wild
tangle can be seen," he remarked, whereupon there was a hurried movement
in that direction, followed by various exclamations to the effect that
the scout master's announcement was indeed true.

"Seems as if the castle must be perched on a high piece of ground,
commanding a pretty good view of the country around," observed Arthur,
as they sought for a broken place in the crumbling wall so as to gain
an entrance to the grounds beyond.

"The story goes that Judge Randall built it that way so he could keep
watch, and know if any of his wife's former suitors were heading this
way," Alec explained.

"Why, he must have been a regular old Bluebeard!" gurgled Billy.

"He was demented on that one subject," confessed Alec, "and the disease
kept getting a stronger grip on him until finally---but hello! here's
the hole in the wall we wanted to find, so let's crawl over the
broken-down stones and enter."

"Hold on," snapped Hugh just then, "I thought you said, Alec, no one
was bold enough to trespass here! If you look down to where I point
you'll see part of a footprint in mud, showing that a man must have
come across this broken wall not half an hour or so ago!"
