"Why, one of our erstwhile German friends has come to life. He was just about to lay hold of us when you came up in the air. Great Scott! What do you think of that?"

"What do I think of what?"

"Why, the Germans in the boat have just shot him."

"Shot whom? The German?"

"Yes; they saw him coming after us and evidently thought he was a friend of ours. Poor fellow! To be shot down by one of his own countrymen. And so goes the last chance the Germans had of learning that we have discovered their plans."

"Then it is a good thing for us they shot him."

"For us, yes. But think of the irony of it!"

"Well," said Frank, "I wouldn't like to have shot him, defenseless as he was; and I didn't want you to. That's why I didn't suggest having a look for him before we came up."

"I couldn't have done it," returned Jack.

"No; nor I; and yet duty would have demanded it. For with him alive, there always remained a chance that he would give the warning."
