"I believe that to be true," replied Herr Block quietly; "otherwise, I would not have raised a hand to help you. Germany must be crushed. There is no room for doubt on that score. If Germany wins, what nation in the whole world is safe?"

"True," said McKenzie. "It's too bad the world could not have realized that a long time ago. The war might have been over by this time."

"As it is," Herr Block agreed, "the war will not be over for years. But come, I am keeping you here idle when I know you are all anxious to be about your work."

He led the way to the street, where a large touring car awaited them.

"I'll drive you as far as the border myself," said the Dutchman.

The four friends climbed in, and the car dashed away in the darkness.

For perhaps four or five hours they rode along at a fair speed and soon, Hal knew, they would once more be within their own lines.

It was half-past four o'clock in the morning when Herr Block stopped the car and said:

"I'll leave you here. You must make the rest of the trip alone."

"Great Scott! You can't get out here in the middle of the wilderness," said Hal.
