Perhaps themost glaring case of want of thought on the part of buildersis illustrated in Fig. 3, which speaks for itself. In connection with the ventilation of an engine-room andstokehold, therefore. I would suggest the following rules :— 1. Use circular ventilating shafts instead of square, acircular section only offering seven-eighths of the resistanceof a square of the same area. 2. Have shafts as short, smooth and air-tight as possible.). So place the up-takes and down-comers as to avoid air.
