carriage work, and still to maintain an equable temperature com- 

 bined with a free circulation of pure air, but to do this windows 

 and doors must not be relied upon. Windows are intended for 

 the admission of light and doors for the passing in and out of the 

 inhabitants. Fresh air must have a means of ingress, and foul air 

 a means of egress peculiar to each, and that altogether separate 

 and distinct from doors and windows; the requirements may best 

 be provided in the following manner: The walls of the stable 

 should be from fourteen to eighteen inches thick, and the inside 

 should be either plastered or faced with glazed bricks, about tv/elve 

 inches above the level of the ground outside. A longitudinal 

 channel should be left in the centre of the wall about four and a 

 half inches wide and nine inches deep, and on a level with this 

 channel, both inside and out, psrforated bricks should be laid 

 alternately; that is to say, the outside perforated bricks should 

 not be directly opposite those inside, but alternate with them. 

 The object of this is, of course, patent to any one, viz., to prevent 

 direct ingress of the fresh air, and vSO obviate a draught, at the 

 same time insuring a constant, continuous and gentle diffusion 

 over the whole building; it is no less important to provide for the 

 due escape of foul air as for the admission of fresh, and to this end 

 nothing can exceed in value an open roof with louvre boards 

 running the whole length of the stable; there is, however, one 

 important objection to an open roof, namely, the exposure to cold 

 in winter and heat in summer; but this may be obviated by hav-. 

 ing a ceiling placed at the same angle as the roof, but about a foot 

 from it, with a large central shaft and side exits under the eaves 

 of the ceiling in the wall. This, of course, does not act so well as 

 the open roof, but it guards the occupants of the stable from the 

 extremes of temperature. By observing these precautious a per- 

 fect ventilation is assured. 



Next to ventilation comes drainage, which in residential houses 

 is not easy to perfect, but in stables it is a simple matter; given a 

 reasonable fall and surface drains are all that is required within 

 the building; each stall or loose box should have a central channel 

 towards which the superficial area of the floor should slope in both 

 directions, and this central channel should empty itself into a 

 main channel running in the longitudinal direction of the build- 

 ing, which in its turn should be discharged into an underground
