EXHIBIT K.

WASHINGTON, D. C., December 6, 1898. SIR: Arriving at the station house just at the sounding of the alarm for fire at the United States Capitol, November 6, 1898, I have no personal knowledge of condition of the gas at that time and place.

From inquiry of Station Keeper J. T. Rollf, who was on duty, I find that about 4 p. m. the leakage was so great that lie notified the gas office of the fact, and from tho sergeant and men on reserve later in the evening that the smell of gas in the dormitory was so great that they were afraid to go to their beds. The leakage was stopped at about 8.30 p. m.

F. F. McCATHRAN, Lieutenant, Ninth Precinct. Dr. CHARLES E. MUNROE,

Columbia University, Washington, D. C.

WASHINGTON, December 6, 1898. DEAR SIR: In compliance with your reqnest for a statement in reference to a leakage in the gas weter at No. 8 engine house on November 6 about 5 p. m., my attention was called by one of the members of this company to the meter, and found upon examination something wrong with the governor on the meter and gas escaping through it. I shut the gas off at the ineter and called the gas office by telephone, and requested them to send a man to remedy the matter. I am unable to state at what time it happened, and have nothing to impress it upon my mind. Very respectfully,

J. T. YOUNG, Foreman. Dr. C. E. MUNROE.
