Mr. Ball. You went to the fourth floor?
Mr. Piper. Yes, at 11 o'clock.
Mr. Ball. And you worked there for how long?
Mr. Piper. I would just take about 10 or 15 minutes to pick up—not quite that long, to pick up the mail and stuff in the fourth floor office.
Mr. Ball. Then what did you do?
Mr. Piper. I came back down to the third floor and picked up and from there to the second and picked up and on to the first floor.
Mr. Ball. Is that what you usually did—was pick up?
Mr. Piper. Yes, sir; every day.
Mr. Ball. Do you do that every day?
Mr. Piper. Yes, sir.
