a prison is made a comfortable place to live in, it becomes useless as
a safeguard against the criminal classes. This is a fundamental
principle. But punishment, although an essential part of imprisonment,
is not its only purpose. Imprisonment should also be a preparation for
liberty. If a convicted man is as unfit for social life at the
expiration of his sentence as he was at the commencement of it, the
prison has only accomplished half its work; it has satisfied the
feeling of public vengeance, but it has failed to transform the
offender into a useful citizen. How to prepare the offender for
liberty is, I admit, a task of supreme difficulty; in some oases,
probably, an impossible task. For work of this character what is
wanted above all is an enlightened staff. Mere machines are useless;
men unacquainted with civil life and its conditions are useless. It is
from civil life the prisoner is taken; it is to civil life he has to
return, and unless he is under the care of men who have an intimate
knowledge of civil life, he will not have the same prospect of being
fitted into it when he has once more to face the world.

In the preparation of this volume I have carefully examined the most
recent ideas of English and Continental writers (especially the
Italians) on the subject of crime. The opinions it contains are based
on an experience of fourteen years in Orders most of which have been
spent in prison work. In revising the proofs I have received valuable
assistance from Mr. J. Morrison.
