That experience having shown me how impracticable in the large majority of cases is any cure of a long-established opium habit while the patient continues his daily avocations and remains at home, [Footnote: In my article upon opium-eating, entitled, "What Shall They Do to be Saved?" published in _Harper's Magazine_ for the month of August, 1867, and hereto prefixed, I have referred to this impracticability in fuller detail. It arises from the fact that in his own house a man can not isolate himself from the hourly hearing of matters for which he feels responsible, yet to which he can give no adequate attention without his accustomed stimulus; that his best friends are apt to upbraid him for a weakness which is not crime but disease, and that the control of him by those whom he has habitually directed, however well-judged, seems always an harassment.] I shall simplify my sketch by supposing that one great object of my life is already attained, and that an institution for the treatment of the disease is already in successful operation. Starting at this fictitious _datum_, I shall carry from his arrival under our care until his discharge a healthy, happy, and useful member of society, a gentleman whom for convenience we will name Mr. Edgerton. Our institution is called not an "Asylum," nor a "Retreat," nor by any of those names which savor of restraint and espionage--not even a "Home," as spelled with a capital H--but simply by the name of the spot upon which it is erected--to wit, "Lord's Island." It is erected on an island because in the more serious cases a certain degree of watchfulness will always be necessary. On the main-land this watchfulness must be exercised by attendants with the aid of fences, bolts, and bars. On an island the patient whose case has gone beyond self-control will be under the Divine Vigilance, with more or less miles of deep water as the barrier between him and the poison by which he is imperilled. For this reason, and because whatever good is accomplished on it for a class which beyond all other sufferers claim heavenly mercy will be directly of the Lord himself, our island is called "Lord's Island." Here our patient will feel none of the irksome tutelage which in an asylum meets him at every step--thrusting itself before his eyes beyond any power of repulsion, and challenging him to efforts for its evasion which are noxious whether they succeed or not; defeating the purpose of his salvation when they do, irritating him when they do not, and keeping his mind in a state of perpetual morbid concentration upon his exceptional condition among mankind in either case. Here he has all the liberty which is enjoyed by the doctors and nurses--save that he can not get at the medicine-chest.
