Without a word Harding led the way directly from the mine. The three German guards looked up as the friends passed and saluted, for Harding, Hal and Chester were all attired in German uniforms that bore captains’ stripes. The three returned the salutes and passed on.
“Now what, Harding?” asked Hal.
“Leave it to me,” was the reply. “I know where there are half a dozen big automobiles, but I’m afraid we’ll have to impress a driver into service.”
“I’ll do the driving,” said Hal.
“Oh, you can drive, eh?” said Harding. “So much the better.”
Fifteen minutes’ walk brought the three friends within sight of the spot where the automobiles were parked.
“Better pick that long, low car there,” whispered Hal. “It looks as though it could show some speed.”
Harding nodded.
Several guards stood about the automobiles. They saluted as the three pseudo German officers appeared, but said nothing. Hal climbed into the driver’s seat of the car he had selected, while Harding and Chester jumped into the tonneau.
“Let her go!” exclaimed Harding, “but slowly unless there is some sign of suspicion. If we start off too fast they’ll know there is something wrong.”
