"What made you tell me all this?"

"'Cause you was good to me and give me a dinner when I was hungry."

"Give me your hand," said Paul, his heart warming toward the boy who exhibited so uncommon a feeling as gratitude.

"It's dirty," said Julius, showing his hand stained with blacking.

"Never mind," said Paul, grasping it warmly. "You're a good fellow, and I'd rather take your hand than a good many that's cleaner."

Julius, rough Arab as he was, looked gratified, and his face brightened. He felt that he was appreciated, and was glad he had revealed the plot.

"Now," said Paul, "you have told me about this man's plans; are you willing to help me further? Are you willing to let me know anything more that you find out about the robbery?"

"Yes, I will," said Julius, unhesitatingly.

"Then I'll depend upon you. What sort of a man is this that you live with? What's his name?"
