"'_The Open-Door System._--It is only of late years that the disuse of locked doors has been regarded as forming an important feature in the administration of an asylum. Detached houses, or limited sections of the main buildings, the inmates of which consisted chiefly of patients requiring little supervision, have long been conducted in some institutions without locked doors. But the general practice of all large asylums has been to keep the doors of the various wards strictly under lock and key....
"'When an attendant could no longer trust to locked doors for the detention of troublesome and discontented patients, it became necessary that he should keep himself aware at all times of where they were and what they were doing. And it therefore became his interest to engage them in such occupations as would make them contented, to provide an orderly outlet for their energies, and to divert their minds from thoughts of escape. The relations of an attendant to his patient thus assumed less of the character of a gaoler, and more the character of a companion or nurse; and it was eventually found that this change in the character of the form of control could be adopted in the treatment of a much larger number of the patients than was at first anticipated. It is not difficult to over-estimate the extent to which a desire to escape affects the minds of patients in asylums. The number who form a definite purpose of this kind really constitutes only a very small proportion of them. The special watchfulness required of attendants in guarding against determined efforts to escape, therefore, need be directed to a few only of those under their charge, and it soon becomes habitual to the attendants to keep themselves aware of where those patients are, about whom they entertain doubt. And it should be borne in mind, in regard to this kind of watchfulness, that its very persistency renders it more easily kept up than if it could be occasionally relaxed. It appeared further that the disuse of locked doors had an influence on some of the patients in diminishing the desire to escape. Under the system of locked doors, a patient with that desire was apt to allow his mind to be engrossed by the idea of watching for the opportunity of an open door, and it was by no means infrequent to find such a patient watching with cat-like eagerness for this chance. The effect of the constantly open door upon such a patient, when the novelty of the thing had worn off, was to deprive him of _special_ chances of escape on which to exercise his vigilance, since, so far as doors were to be considered, it was as easy to escape at one time as another; and it was found that the desire often became dormant and inoperative if not called into action by the stimulus of _special_ opportunity. It is, indeed, a thing of common experience that the mere feeling of being locked in is sufficient to awaken a desire to get out. This happens both with the sane and the insane; but it is certain that the mental condition of many patients in asylums renders them likely to be influenced in an especial manner by such a feeling. With many, however, the desire to escape dies away when it ceases to be suggested by forcing upon their attention the means of preventing it.
