Arrows show direction of currento. 1* 10 HEATING AND VENTILATIOM. VENTILATION. Ventilation is either natural or mechanical or both, the firstbeing by means of openings, such as windows, doors, etc.; thesecond, by means of fans or chimneys, and the third, bothcombined, generally for summer ventilation. MECHANICAL Movement: Aspirating chimneys exhaust the air fromthe rooms, thus creating a partial vacuum for the pure air tooccupy, coming in through the proper openings. The move-ment of the air in the chimney is produced by heating andrarefying the air in it; the external air, being heavier, tends topush it up out of the chimney; the fire or heater should beat the lowest point of the chimney. Exhaust fans fulfill thesame functions as aspirating chimneys ; they may be locatedunder the roof, or in the cellar—the foul air from them beingconveyed, through ducts or shafts, away fi-om the vacuum movement requires the doors and windows to bekept closed, during
