It was the custom in the State of Maryland to require the free colored people to have what were called free papers. These instruments they were required to renew very often, and by charging a fee for this writing, considerable sums from time to time were collected by the State. In these papers the name, age, color, height, and form of the freeman were described, together with any scars or other marks upon his person which could assist in his identification. This device in some measure defeated itself--since more than one man could be found to answer the same general description. Hence many slaves could escape by personating the owner of one set of papers; and this was often done as follows: A slave, nearly or sufficiently answering the description set forth in the papers, would borrow or hire them till by means of them he could escape to a free State, and then, by mail or otherwise, would return them to the owner. The operation was a hazardous one for the lender as well as for the borrower. A failure on the part of the fugitive to send back the papers would imperil his benefactor, and the discovery of the papers in possession of the wrong man would imperil both the fugitive and his friend. It was, therefore, an act of supreme trust on the part of a freeman of color thus to put in jeopardy his own liberty that another might be free. It was, however, not unfrequently bravely done, and was seldom discovered. I was not so fortunate as to resemble any of my free acquaintances sufficiently to answer the description of their papers. But I had a friend--a sailor--who owned a sailor's protection, which answered somewhat the purpose of free papers--describing his person, and certifying to the fact that he was a free American sailor. The instrument had at its head the American eagle, which gave it the appearance at once of an authorized document. This protection, when in my hands, did not describe its bearer very accurately. Indeed, it called for a man much darker than myself, and close examination of it would have caused my arrest at the start.
