ated on the southwest
corner of Camden and Eutaw Streets. It was in a handsome three-story
brick building and had a massive marble entrance. Adjoining it was what
had formerly been a slave pen. Between the corner building and the slave
pen there was an open court which had been used for the slave mart. The
slave pen we used for our prison purposes. The first floor of the main
house was used as our public offices. The second floor was General
Woolley's headquarters. The third floor was my headquarters. In the rear
of the main front corner building was a three-story brick extension,
running back about a hundred feet (to an alley) in which were quartered
the troops (our guards). The buildings were admirably constructed and
centrally located for our purposes.

From now on I was Assistant Provost Marshal General and Chief of the
Secret Service. I had a corps of about forty (men and women) under my
direction. To illustrate my general lines of work I will give copies of
some memoranda which I have. To give all would take more room than I can
spare. In looking these memoranda over the greatest gratification I
feel comes from the evident fact that I was not a drone, but tried to do
my duty. And fifty years further along in our nation's history it may be
a satisfaction to my then living relatives to know it.

Confederate mail carrier--W. V. Kremer's report on the "Disloyals" north
of Baltimore.

The Secret Service, as its name implies, is the most confidential arm of
the service. Its information intelligently guides the commanding
general. It gives him to know of the conduct of the enemy and discloses
weaknesses, if any exist, in his own armour. There is always a "cloud of
mystery" thrown around it by outsiders. But its pursuit, on the inside,
is not that of romance, but simply of cold facts; it deals with business
propositions. In telling my stories, not being a story writer, I shall
tell plain facts, leaving the reader to clothe them with the glamour
that a fiction writer would usually apply. Were I to attempt to tell
something of all my many stories it would weary a reader; so I will try
to select some that are really historic, or interesting from their
unusual ch
