The arrangement of the building is made with true regard to ventilation. At each end, in the centre of the building, a large hall, containing a superficial area of 425 feet, is carried up to the roof of the house, on which is constructed a large ventilator, containing windows hung on centres, and moveable with a line, to admit any circulation or change of air required. The several rooms throughout are arranged to open at once into the landing of the stone stairs, which are carried up in this space. The several doors have semicircular arches above them to be opened as occasion may require; and which, without producing any strong current, would always effect an extensive ventilation during the occupation of the rooms. The usual manner of ventilating the common sleeping rooms, is by placing the windows on each side of the room, which are very useful, but chiefly so after the paupers have left the apartment. The windows throughout are constructed with the upper part hinged, and to fall inside, which allows them to be opened during rainy weather. Cast-iron air-gratings are to be inserted in small flues formed in the walls, and fixed a few inches above the floors, for obtaining, when required, an admission of external air. A A A A, yards.

When we call to mind the interminable discussions which only a few years ago were usual in every society, as to the necessity, or advantages, or practicability, of a poor-law system in Ireland, and then transfer our attention to the actual progress which has been made in carrying into effect a certain, defined, and enacted arrangement, it is something like escaping from a dark, close wood, in which there was neither path nor direction, into an open country, with the bright canopy of heaven above, and our desired destination, or the sure road conducting to it, plainly in view. To devise, and, much more, to bring into operation, a legalized system of poor relief suited to the wants and circumstances of Ireland, will, when duly considered, appear to have been a truly great and formidable undertaking. Innumerable plans had been set forth from time to time for this purpose, anterior to the act passed among the first of her present Majesty’s reign; but it may well be questioned if there was any one of them which would not on trial have proved to be a complete failure. Into that speculation, however, we have no occasion to enter at present, as there is now a law, having its machinery already so near to completion, that it must be in full effect at no distant day throughout the whole country, to the provisions and execution of which it will be at once more interesting and more profitable to direct our attention.
