While a good deal may be said for such a prison from the standpoint of its mechanical heating and ventilation, from the standpoint of the welfare of the prisoner hardly too much can be said against it. The great disadvantages of the cage type of cell are the complete loss of all privacy to the inmate, the inhuman and grotesque appearance which it gives to his confinement, and the difficulty of providing really adequate segregation and classification. Important prisons like the Great Meadow Prison of New York State and the prison at Stillwater, Minn., both of which are renowned for enlightened and efficient administration, have this inside cell arrangement. These prisons, however, were constructed when very little was known of the outside cell construction, and many practical prison men were largely against its adoption. There is really no place in this country where it is possible to study adequately the outside cell, long advocated by our more progressive penologists, so that the author made a tour of Continental prisons for the sole purpose of discovering wherein lay their advantage and how they should be designed to make them suitable to this country and climate. CONTINENTAL CONSTRUCTION In the Continental prison the chief difficulty with the outside cell is found in its ventilation. In England the windows are intentionally made loose fitting so that they cannot lie entirely closed. Where it is possible to close the windows tightly, insufficient ventilation invariably results during cold weather because the great majority of prisoners seem to shun fresh air and invariably keep their windows shut.
