Not illustrated. 1893 Excerpt: ...for the hot foul air under the roof or ceiling should be provided, for which ridge roofs, gables, and clerestory windows in churches offer facilities of which architects rarely avail themselves, precautions being taken against down draughts, and there should also be means for perflation by windows, especially in the upper part of the room space where the hot foul air rises. It would be well if the extraction of impure air by a furnace were kept up when, though there is no demand for artificial warmth, the outer temperature, wind, or rain would preclude any free ventilation by open windows. For the ruder ventilation of stables, cow-sheds, &c., inlets in the walls about six feet from the ground with louvre boards directed upwards, and outlets in the roof, either wide tubular shafts topped by a Sugg's cowl, or smaller tubes with any efficient exhaust cap or louvred dormer or pent-house ventilators. For temporary hospital or camp-huts the army plan of double hoarded walls, weather boards on the outer, and match-boarding on the inner side, the latter stopping short six inches or thereabouts from the top, and the outer leaving a like space below, except that the lowest board, instead of being left out altogether, is slanted outwards so as to throw off the rain.

It is equally suitable for any building, as workshops, cowsheds, &c., where an ample supply and renewal of air, without much draught, is a greater consideration t...
