“Not necessarily,” replied Adrian. “Sometimes revolutions are started by men to overthrow a bad government. But my mother has always taught me there was a better way to right a wrong than to go to war over it. That’s why I am in favor of doing all we can to help those who want to prevent trouble.”

“Of course if you put it that way,” said Donald, “I’ve no objection to the excursion, as the captain calls it.”
