The following pages treat of hell--A Kansas hell and a Missouri hell. Those who desire to peruse works that tell about Heaven only, are urged to drop this book and run. I was an inmate of the Kansas penitentiary for sixteen months, and make mention of what came under my own observation in connection with what I experienced. While an inmate of this prison I occupied cells at various times with convicts who had served terms in the Missouri prison. From these persons I gathered much useful material for my book. After my release I visited the Missouri penitentiary, and verified the statements of those criminals, and gathered additional material from the prison records and the officials. I have written chiefly for the youth of the country, but all ages will be deeply interested in the following pages. A large majority of the convicts are young men from sixteen to twenty-five years of age. They had no idea of the terrible sufferings of a convict life, or they surely would have resisted temptation and kept out of crime. The following pages will impart to the reader some idea of what he may expect to endure in case he becomes entangled in the meshes of the law, and is compelled to do service for the State without any remuneration. Every penitentiary is a veritable hell. Deprive a person of his liberty, punish and maltreat him, and you fill his life with misery akin to those who wander in the darkness of "eternal night," I think, when the reader has perused the following pages, he will agree with me, that the book has the proper title. That this volume may prove an "eye-opener" to the boys who may read it, and prove interesting and instructive to those of mature years, is the earnest wish of the author.
