The Johnson System is the standard and maybe found in ninety per cent, of the school andcollege buildings now equipped with any sys-tem of temperature control. Methods of Heating.—The methods of heat-ing school buildings may be divided under twoheadings: individual, in which the heat isradiant; and central, in which the air is heatedby convection. Generally speaking, the firstmethod, in which a stove is to be employed, isimpractical in all but the one room school. Theventilation, such as it is, is limited and by nomeans equal to the poorest gravity system. Acentral heating system may consist of a furnace,steam, or hot water boilers, which in turn maybe either direct or indirect. The open grate orEnglish fire place, while offering possibly thebest ventilation for small schools is very rarelyused in this country, and therefore, need not beconsidered. It is an extremely poor heater, isdangerous, and does not compare in service withthe jacketed stove. 147. 75 c~a K•n •o (J en CO P c< I—I < rt PS g, p I < o . en ? 2^ u COW w pq m 3 148 Heating and Ventilation Stove Heating.—In the small countryschools heating by stoves is most a stove is employed it is best surroundedby a sheet iron jacket extending from the floorto about six inches above the stove top. A freshair inlet is provided in the floor under the stove,and connected by means of a metal duct with theoutside. The chimney is arranged to contain avent flue with a register near the floor line tocarry off the cold and vitiated air. Valves areplaced in fresh air and vent ducts to be closed atnight. The system is troublesome, dirty, dis-turbing, though very economical. 90 per cent,of the heat generated is used. Furnace.—There are two ways of employingfurnace heating, namely, through the gravity andthe fan system. In very small buildings only, orwhere certain conditi
