I know nothing of the private biography of Mr. Ivy, and it is quite possible that he may have possessed endearing traits which he had no opportunity to manifest in our intercourse. It would be foolish and futile for the ends I have in view in this writing to cite or comment on individuals, save as they may illustrate the point under discussion. But I am the less reluctant to animadvert upon this or that employee of the penitentiary, because I feel satisfied that, so far from compromising him with the higher prison authorities, abuse from me would only recommend him to their favor.--Mr. Ivy, such as he was, conducted us to a bench outside a closed door, already partly occupied by three or four half naked convicts, white and black. We gathered from his gestures of head and club that we were to remove our upper garments and our shoes and stockings, and place them on the floor in front of us. It was a cold morning, and the floor was of limestone. We obeyed instructions, and for the next twenty minutes sat there, objects of pardonable curiosity or amusement to our fellow benchers and to passers-by in the hall, and with nothing to keep us warm but the genial influences of the occasion. Finally, each in his turn, we were passed through the door into a sort of office, with clerks and Dr. Weaver, the prison physician, at $1500 a year,--a tall, wooden faced young medical school graduate, who cultivated a skeptical expression and a jeering intonation of speech. He and an assistant put us through a physical examination, and took a series of measurements, all of which were entered by the clerks in ledgers. Our photographs were then taken, and afterward (it was the next day, but may as well be told here) we were further identified by taking the impressions of our finger prints, and by a second photograph without our mustaches--these having been removed in the meantime. We were now convicts full-fledged and published, and our pictures were disseminated to every prison and penitentiary in the country, to be enshrined in the rogues' gallery and studied by all police officials.
