After they had parted for the night, the man who had lost his memory had studied the little book given to him, and had learned more or less the system under which Ireland lay. The whole island, he learned, was the absolute and inalienable possession, held under European guarantees, of the enclosed Religious Orders, with whose dominion no interference was allowed. All the business offices of the country and the ports of the enormous agricultural industries were concentrated in Dublin and Belfast; the rest of the island was cultivated, ruled, and cared for by the monks themselves. (He read drearily through the pages of statistics showing how once again, as in medieval days, under the labour of monks the land had blossomed out into material prosperity; and how this prosperity still increased, year by year, beyond all reckoning.) Of men, there were the Carthusians, the Carmelites, the Trappists, and certain sections of Benedictines; of women, there were the Carmelites, the Poor Clares, the Augustinian canonesses, and certain other Benedictines. Special arrangements between these regulated the division of the land and of the responsibilities; and the Central Council consisted of the Procurators and other representatives of the various bodies. In return for the possession of the land, and for the protection guaranteed by the European governments, one, and one only demand was made--namely, that a certain accommodation should be offered--the amount determined by agreement year by year--both for these Retreat-houses in general, and for what were called "Hospitals-of-God" in particular. These hospitals were nothing else in reality than enormous establishments for the treatment of the mentally unbalanced; for it had been found by recent experience that the atmosphere supremely successful in such cases--especially those of certain well-marked types--was the atmosphere of the strongest and most intense religion. Statistics had shown without a doubt that, even apart from cases of actual possession (a phenomenon perfectly recognized now by all scientists), minds that were merely weak or subject to mental delusions recovered incalculably more quickly and surely in the atmosphere of a Religious House than in any other. These cases too were isolated with the greatest care, owing to the extraordinary discoveries recently made, and verified over and over again in the realm of "mental infection."
