The next morning they suggested that, inasmuch as we were about entering a slave State, it would be well, before leaving New-York, to procure free papers. The idea struck me as a prudent one, though I think it would scarcely have occurred to me, had they not proposed it. We proceeded at once to what I understood to be the Custom House. They made oath to certain facts showing I was a free man. A paper was drawn up and handed us, with the direction to take it to the clerk's office. We did so, and the clerk having added something to it, for which he was paid six shillings, we returned again to the Custom House. Some further formalities were gone through with before it was completed, when, paying the officer two dollars, I placed the papers in my pocket, and started with my two friends to our hotel. I thought at the time, I must confess, that the papers were scarcely worth the cost of obtaining them—the apprehension of danger to my personal safety never having suggested itself to me in the remotest manner. The clerk, to whom we were directed, I remember, made a memorandum in a large book, which, I presume, is in the office yet. A reference to the entries during the latter part of March, or first of April, 1841, I have no doubt will satisfy the incredulous, at least so far as this particular transaction is concerned.
