"They have," said Mr. Penton.
"Yes, and that act of theirs is sufficient to earn for them the Medal of Honor. I never knew of a braver act," added the president. "Rush, come here! Jarvis, I want you, too."
The boys obeyed the command, Steve leading the unwilling Italian around the chutes to the platform, where he stood him against the wall.
