In the preparation of this work, I feel I am under lasting obligations for discriminating advice and kindly suggestions tendered me at different times by many friends. But I am under special debt to Mr. George H. Sandison, Managing Editor, and J. A. Belford, Art Editor of the Christian Herald, for valuable suggestions.

I also express my sincere thanks to the Rev. Madison C. Peters, D. D., whose clarion voice against wrongs and abuses of various kinds has been heard all over Greater New York, for many helpful suggestions. I am also thankful to many of the New York magazines and papers for kind words and much interest in articles of mine on Prison Work that have appeared from time to time. These magazines and papers include Harper’s Weekly, Success, Van Norden, Intelligencer, Christian Advocate, Examiner, Press, Presbyterian, Witness and many others.

I extend my thanks also to Messrs. Harper & Bro., for the use of a cut, and to the Evening Journal for the loan of photographs.
