"Got anything up your sleeve?" asked Billy.
"An idea just came to me," replied Frank. "I don't know whether it's any good, but perhaps it's worth chewing over."
"Let's have it," demanded Billy eagerly.
"Well," said Frank slowly, "I figure that there must be about twenty Germans in that detachment just opposite us. What would be the matter with a few of us going over there some dark night and cleaning up the bunch?"
A delighted shout met the suggestion.
"Bully!" exclaimed Bart.
But though the approval was enthusiastic, practical difficulties soon presented themselves.
"How are we to get across?" asked Bart dubiously.
"We haven't any boat on this side that's big enough," said Billy. "In fact, I don't think we have any at all."
"That's an easy one," answered Frank. "Do you see that big lobster of a boat on the other side? That looks as though it would carry almost a dozen anyway. We won't need any more than that to nab the Huns, because we'll have the advantage of the surprise if our plans go through all right."
