“Are you mad, or are we?” he asked. “Or was there a bird there? Or are you a hypnotist?”

He got up quickly.

“Phil, I swear I saw a bird, and heard it sing,” he said excitedly. “It was sitting there, there on his finger. What has happened? Go on, Tom—tell us what it means.”

Philip, with his gold and his Stock Exchange and his business generally, does much more curious things than that. But, personally, I do not find them so interesting.”
