“T—try?” Johnny stammered at last. “Try to take pictures of people’s thoughts?”

“Yes, yes.”

Once again Johnny stared. “Nothing,” he thought, “could be more interesting. And yet—

“Oh bother!” he whispered at last.

Then to the Chinaman, “Yes, I sure would!”

“All right.” The Chinaman’s eyes narrowed. “You do for me, I do for you.”

“Do what?” Johnny asked.

“Not very much.” Tao Sing’s eyes became mere slits of light. “You know Wung Lu?”

Johnny nodded.

“Wung Lu very rich, very wise.” The little man’s eyes opened suddenly very wide. “You see Wung Lu sit and think long time, eyes half shut. Think long time. Very wise thoughts. You take picture of these thoughts. Tao Sing read thoughts. By and by Tao Sing very wise. You take picture Wung Lu’s thoughts. You give ’em to Tao Sing. What? You take ’em pictures your friends. All right. You keep ’em. What?” He looked at the boy very hard.
