In a flash it all came back to Frank and he buried his face in his arms.

“Poor old Jack,” he said. “I wish I could have stayed in his place.”

At that moment a figure on the other side of him moved. Faintly interested in spite of his grief, Frank turned to see who it might be. As his eyes fell upon the figure, which was now rising to a sitting posture, they almost bulged from his head, and he cried out in a voice of amazement:

“Jack!”

Jack looked around slowly.

At first he was unable to gain his bearings, but in a moment the past came back to him.

He reached out and took Frank by the hand.

“Yes, it is I,” he said quietly. “I had a most miraculous escape. I’ll tell you about it.”

“Don’t tell me now,” said Frank, squeezing his chum’s hand. “It’s enough for me to know that you are alive.”

An officer entered.
