The treatment of criminals under sentence of imprisonment must now be well known to the public. Repeated discussion and innumerable writings have rendered it familiar to every body. A man is condemned to undergo, let us say, three years' incarceration in a jail. A portion of the time is to be spent in hard labour. He commences his imprisonment with no other earthly object than to get through it with the least possible amount of suffering. Employment, which might, under better circumstances, be a pleasant resource, is distasteful to him because it is compulsory, and because it is productive of no benefit to himself. The hours that are unemployed are passed in company with others as bad as, or worse than, himself. They amuse themselves by recounting the history of their lives, their hairbreadth escapes, their successful villanies. Each profits by the experience of the whole number, and stores it in his memory for future guidance. Every good impulse is checked, and every better feeling stifled in the birth. There is no room in a jail for the growth of virtue; the atmosphere is not congenial to its development. The prisoner, however well disposed, cannot choose but listen to the debasing talk of those with whom he is compelled to associate. Should he resist the wicked influence for a while, he can hardly do so long. The poison will work. By little and little it insinuates itself into the mind, and vitiates all the springs of good. In the end, he yields to the irresistible force of continued bad example, and becomes as bad as the worst.
