Can you tell the committee whether, prior to July last, there were any differences existing between the Pennsylvania Railroad Company and its employés? A. On that subject I have no personal knowledge. Any differences, if they did exist, between the employés and the company were known to the operating officers of the company, over whom I have no control. I only know it as a matter of public history, as other persons. Q. Were you present at the disturbances of the peace within the city of Pittsburgh in July last? A. I was during a portion of those disturbances, but not during all of them. If it is desired that I should give you a connected statement of what I did see, I would begin with where my personal knowledge of the transactions commenced. Q. That is what the committee desire?
