The citizens of Pittsburgh are rising to-day to defend themselves from the threatened revolt against law and property. This is a ringing answer to the tones that already come from other cities, that Pittsburgh is honored in the manhood and public spirit to put down mob law. The people are responding to the mayor's call by thousands. Let not enlistments slacken, however. Now is the time to display such a force that resistance will be seen to be in vain, and effusion of blood prevented. We are proud to say that the Nineteenth and Fourteenth regiments of militia are redeeming themselves from the fault that they committed on Saturday, and are now mustering strength and will. By night this issuing would be and will be decided, and we hope by Harrisburg and Allegheny efforts alone.

By Senator Yutzy:

Q. Who was your reporter that reported the occurrences of the riot during Friday, Saturday, Sunday, and Monday?

A. Well, we have a corps of about five or six regular men, and during these three or four days, we employed a great many others. We gave page after page of matter about, and it would not have been possible for one or two or three or four to get it up. I can give you the names of a number of them. The man whom we had stationed close to the round-house during Saturday night, was named Mr. George Vickers. He is now, I think, on the Philadelphia Times. Mr. John Haslet and Mr. William Clark, and a number of others. Mr. Henry Myer was assisting us some.

Q. Had you more than one edition on that Sunday of the riot?

A. Yes. Had three editions.

Q. They are all on file, are they?

A. Think they are, ain't they?

Q. Will you please examine this article, and say whether you are author of it. [Indicating article of July 20, headed "Let them Go.">[

A. Yes, sir.
