The uppernioit' of the three figures iTprosencs a se6tion of the ^v•hf.le structure. A, the dairy in the centre, sur- roundei by open passages. B, the entry to the dairy f/om the !)orth. C, the ice-house. D, the scullery, or wash-liou^e, vrith the door or entrr.nce f om the south, and benches placed I>eneatli. f, a door, Ahich communicates V.'ith the milk-hoase, &:c. /:. the hre-place. The lowermost of t'^e three figures, is r.n elevation of the milk- house A. B B, the passages round it. r, the interior window. (!, the ventilator or air pipe. if, the exterior window. I'he smallest of the figures above M I L glvr.n, is a delineation of the ven- tilator. i, represents the valve at the top. k, another valve at the bottom, which communicates with the milk- house, 71, a similar valve, with the pas- sage. The whole of this structure ought to consist of a range of nar- rov.' buildings, as in the section first delineated, where the middle division marked A, represents the viilk-kouse, properly so called. Dr. ANDEfisoN directs it to be built with a double wall, so that a cui'- rent of air may continually pass, for the purpose of preserving a re- gular, cool temperature ; the inner wall being construiS.ed with lath or bricks, doubly plastered on both sides ; and the outer one, consist- ing of plastered lath : both being carefully worked, so as to render them perfedly air-tight. The entrance to the dair)- ought to be on the north side B ; but it v/ill be requisite, for greater con- venience, to make another com- mur,ication through the door f, into the front-room, especially dur- ing the winter, when the outer door B, should be kept continually shut. The external roof ought to be con- structed with tiles, or slate, while the inner one should be made of plaster, closely applied. Between both, it will be necessar}' to leave a vacant space, at least four feet wide, for the free passage of air, as delineated in the elevation above given; in which the letter A, re- presents the inside of the liiilk- house. The lq,ttfcrs B B, designate the area between the two walls, that graduall}' diminishes towards the top, till it terminates in the ventiiator oj wooden chimney d^ W'hicU
