Mr. Jenner. All right. I'll get to that. Have you ever been called upon by either any agency of the Government of the United States or of the State of Texas or the City of Dallas to do any interpreting or translating?
Mr. Mamantov. Yes, I was called by the police force for the City of Dallas around 5 o'clock, November 22.
Mr. Jenner. What year?
Mr. Mamantov. Of 1955, on 2 or 3 minutes' notice.
Mr. Jenner. It was 1955 or 1963?
Mr. Mamantov. Excuse me, 1963.
Mr. Jenner. I got from what you have said, then, you had no prior notice?
Mr. Mamantov. No; sir.
Mr. Jenner. You were called by some official of the city police department?
Mr. Mamantov. Yes; I was called by Lt. Lumpkin. I think he's Lieutenant—they call him Chief.
