“A great victory has been won for our cause,” he said. “I cannot tell you its exact nature; but among us are those who worked long. They are here to-night, after a long absence.

“I welcome them, in the name of the cause. Before this week is ended, our leaders in Russia will have plans that will enable them to defeat their enemies in aerial warfare.”

“You are the one that I have chosen. I rely on you to destroy the enemies to the cause which you represent.

“Remember: Destroy, even though it may mean your own life. We are willing to die for our cause.”

“We are willing to die,” responded the members of the group.

The man who held the bomb stood motionless. The others crowded about him for a few minutes, while they looked at the piece of mechanism in his hands.
