“Why, right in Heligoland, sir.”

“But the mines?”

Frank shrugged his shoulders.

“The Germans don’t pay much attention to our mines,” he said.

“Well, no, they don’t, that’s true,” agreed Lord Hastings.

“Besides,” said Jack, “we can go beneath the mines.”

“I guess we could do that,” agreed Lord Hastings. “While we cannot tell just where the mines lay, we have, nevertheless, a first-class map of Heligoland and the sea surrounding, and by paying careful attention we may be able to get through safely.”

“Then we shall make the attempt, sir?” asked Frank eagerly.

Lord Hastings smiled.

“Yes,” he said quietly.
