The cell doors operate on an automatic device, with which it is possible to open all the doors at once, or each one individually. The author’s contribution to this device was that they could also be locked five inches open. In this way it is possible in warm weather to ventilate the cell into the central corridor; which in turn is ventilated at each end by accessible windows across its entire width. It is true that the prisoners can look out through the five-inch opening and communicate with one another across the corridor; but if this privilege is abused, the door can be closed separately and the offending inmate may be disciplined without affecting the comfort of the others. In the new cell block at the Eastern Penitentiary at Philadelphia the cells have been equipped with two doors--one of solid wood and the other an iron grating. In warm weather the grating only is used, and if a prisoner becomes unruly or noisy, the wooden door is closed. The upper portions of the doors at Westchester are glazed, as they always should be, because it is necessary for the guard at all times to see if the prisoner is in his cell. Almost the whole problem of the outside cell lies of course in the window. Our climate is such in summer that it would be almost inhuman to put a man in a cell and shut the door without providing adequate window area. The English cell with its small window opening would be intolerable here. So would those in the Holland and German prisons, where the windows are hinged at the bottom and open at the top. The Westchester windows are steel sash of the usual casement type except that they are pivoted top and bottom 4 inches from the jamb. This enables the window to be readily cleaned on each side. The window opens at right angles to the wall, and the opening is entirely adequate for our weather conditions, the window being two feet wide and four feet high. The adjuster is a commercial type, and will keep the window open at 90 degrees, 45 degrees, and about 15 degrees. Proposed Plans of the Detroit House of Correction _By_ ALBERT KAHN, _Architect_ The plan of the new Detroit House of Correction is the result of a careful survey of the most recently designed penological institutions and the assembling of what was considered best about them, adding such features as seemed desirable to the Hoard of Commissioners and its architect. CORRELATION OF DIVISIONS Foremost in the general scheme is the proper correlation of the various divisions, for administration, the admission, care, and education of prisoners; the workshops and recreation courts. With all, the idea of preserving the prisoner’s self-respect as far as possible and impressing him with the idea that while he must receive deserved punishment, every chance of rehabilitation is offered him.
