castle.

"The place has several visitors to-day?" hinted Hal.

"Oh, yes; it is one of the show spots of this section," replied Mlle.
Nadiboff. "It does well enough to look about there for a few minutes.
But a ruin like that suggests death and decay, and I--I love life."

"Still, that castle is now a part of history," suggested Hal, "and
history, it seems to me, should always be interesting."

"This stupid young engineer!" fumed Mlle. Nadiboff, to herself. "He
would drive me wild, if I saw much of him. I think even my slow little
captain will prove more romantic."

Though neither of the submarine boys could yet suspect it, they were soon
to stumble into much more than relics of the past.

They were destined to find themselves exposed to one of the greatest
surprises of their already eventful lives.

"Here we are," cried Mlle. Nadiboff, as the auto stopped near the north
end of the castle. "May you discover something to interest you!"

The submarine boys certainly did!
