them know the truth, and to ask themselves what should or could be done to end a situation so degrading to every one concerned in it, from one end of the line to the other. The situation, indeed, seems all but incredible. Your first thought on being told of it is, It must be an exaggeration or a fabrication. On the contrary, words cannot convey the whole horror and shamefulness of it. I am conscious of having left out a great deal of it. I found as I went on with this writing that the things to be said were restricted to a few categories. First, the physical prison itself and the routine of life in it must be stated. That is the objective part. Then must be indicated the subjective conditions, those of the prisoner, and of his keepers--what the effect of prison was upon them. Next was to come a presentation of the consequences, deductions and inferences suggested by these conditions. Finally, we would be confronted with the question, What is to be done about it? Such are the main heads of the theme. But I was tempted to run into detail. Here I will make a pertinent disclosure. During my imprisonment I was made the confidant of the life stories of many of my brethren in the cells. I am receiving through the mails, from day to day, up to the present time, other such tales from released convicts. The aim of them is not to get their tellers before the public and win personal sympathy, but to hold up my hands by supplying data--chapter and verse--in support of the assertions I have made. They do it abundantly; the stories bleed and groan before your eyes and ears, and smell to heaven; the bluntest, simplest, most formless stuff imaginable, but terrible in every fiber. Before I left prison I had accumulated a considerable number of these narratives, and had made many notes of things heard and seen--data and memoranda which I designed to use in the already projected book which is now in your hands. Such material, however, would have been confiscated by the Warden had its existence been known, and none of it would have been permitted to get outside the walls openly. The only thing to do, then, was to get it out secretly--by the "underground railroad."
