Mr. Dougherty. No, sir—just a short length of time.

Mr. Ball. Then what did you do?

Mr. Dougherty. Well, then, I went back to work.

Mr. Ball. And where did you go to work?

Mr. Dougherty. Let me see—oh, up to the sixth floor.

Mr. Ball. Did you go to the sixth floor?

Mr. Dougherty. Yes, sir.

Mr. Ball. About what time?

Mr. Dougherty. Oh, it was about 12:40—it was about 12:40.

Mr. Ball. Had you heard any shots before that?
