After a while he came back. "Do you know what I asked you?" he inquired.

"No," said I.

"Then why did you say twenty-one and twenty-second?"

"That is my age," said I.

"Oh!" said he; "but I did not ask your age. You did not hear?"

"No," said I.

"What is your reg-i-ment?" he asked very distinctly.

Now it was clear enough that all this thing was a dream. For a man in real life to ask such a question, it was impossible. I felt relieved of many fears.

"What are you smiling at?" he asked.
