As I before remarked, it is notsafe to depend upon the wind for this purpose ; and the only re-maining agent is the diminution in its specific gravity when air iswarmed by respiration. By taking advantage of this principle,the foul air is carried oif from the upper parts of the stable if ashaft is fixed there for its passage. Sometimes a small shaft is in-troduced over the head of each horse; but in practice it is foundthat one large shaft, about a foot square, will purify a stable con-taining four or five horses. It is better to fix this about the mid-dle of the stable, as regards its length, but near the heads of the VENTILATING SHAFT. 167. VENTILATING SHAFT. horses, as shown in the above section of a stalled stable. The tubemay be made of wood—and, indeed, this material is better thaniron, because it does not condense the steam as it ascends nearlyso much as metal, and there is less dropping of water from it. Theupper end of this shaft should be guarded from down-draughts,either by a cowl which will turn with the wind, or by a coveredventilator of galvanized iron fixed on the ridge of the roof, theprice of which will depend onthe size. At the bottom, a sheetof iron, considerably larger thanthe shaft, should be fixed aboutthree inches below the mouth, soas to prevent any down-draughtstriking the horses; and also tocatch any drip from the conden-sation of the steam of the stable,as it comes in contact with theinterior of the shaft. This, however, will be almost entirelyavoided by making the shaft of wood, as I have already bo
