Plans for public schoolhouses approved by the state superintendent of public instruction with explanations, specifications, bills of material, estimates of cost . eplace the air that has just arisen from the casing, alarge volume of fresh air rushes in through the large pipeleading from outdoors into the casing.

As the casing is practically heat-proof, the air within it isvery quickly and thoroughly heated, and the foregoing processcontinues. As the air at the ceiling gradually cools it settlestoward the floor, carrying the foul air with it. The foul airis drawn otf through the ventilating register into the chimney,where the patented chimney attachment prevents its acting asa check on the furnace draft. The remainder of the cold air is drawn up into casing,heated and recirculated. The warmer fresh air from abovesettles down to take its place.
