Mr. Stevenson. Captain Nichols, I am sorry, was in charge of the automobile theft bureau. Capt. F. M. Martin was in charge of the juvenile bureau. Capt. W. C. Fannin was in charge of the burglary and theft bureau.

Mr. Hubert. Just to get the record clear, insofar as Captain Nichols is concerned, you indicate he was off on 1 day of the 3-day period. Which day was that?

Mr. Stevenson. I believe that was the 24th.

Mr. Hubert. Now each one of these bureau chiefs reports to you and is responsible to you, is that correct?

Mr. Stevenson. That's right; yes, sir.

Mr. Hubert. Who are you responsible to?

Mr. Stevenson. To the assistant chief of police.

Mr. Hubert. Who is that?

Mr. Stevenson. Chief Charles Batchelor.

Mr. Hubert. In the course of this examination, it would be helpful to us if you would try to state an approximate time as to each episode or fact that you testify to, and also indicate whether the fact or matter or episode that you are testifying to is within your own knowledge; that is to say, gained from your own observation, or whether the information you give us was obtained from someone else, in that case, tell us if you can remember who gave you the information.
