"The amount of force necessary to carry out such an undertaking as I have indicated, will necessarily be very large, and the assumption of disguises and characters by my operatives, will be a very important item in itself," etc., etc., etc.

My views were carried out just as they were set forth in this letter, and I was soon hard at work in my efforts to "regulate" the District of Columbia. It was too true that a great majority of the local police were disloyal, and could not be depended upon to faithfully discharge their duties to the government that employed them; therefore, in addition to my other work, I exerted myself to the utmost in aiding the municipal authorities to reorganize and discipline the police of the district.

Many personal incidents worthy of note occurred during this period, but there was one which I recall at this moment with a laugh at my own expense—an incident in which I was reluctantly compelled to occupy the wrong side of a guard-house over night, and instead of capturing a prisoner became a prisoner myself.

GUARD-HOUSE PRISONERS.
