76 Ventilation with Heating. 



the animal walks along, and remaining very much in the place 

 where it has been ejected. The question of ventilation, when 

 artificial warmth is not required, is however outside our present 

 consideration, as before stated. It is plain that it would greatly 

 facilitate the matter if instead of 2,000 cubic feet per hour per 

 head, we could get a comfortable wholesome atmosphere with 

 200 or 300 feet. This would reduce the cost of heating to one- 

 sixth, or one-tenth, of that required for 2,000 feet, and would 

 in the same proportion reduce the risk of sensible drafts. This 

 is perhaps too much to expect, but it is a direction worth ex- 

 perimenting in. Besides, we have to remember that from the 

 patience with which people suffer under the present state of 

 affairs, they may be expected to be exuberantly happy with a 

 state of affairs that will not more than a quarter choke them. 



What led up to this idea was the ventilating and heating of a 

 new National School in a district where, in a neighbouring 

 school, the people seemed to be eminently indifferent both to 

 heat and ventilation. This latter school was found in a raw 

 stormy day with the fire extinguished because of a smoky 

 chimney, and the door wide open to prevent the shivering chil- 

 dren being absolutely poisoned on going out of the fresh air 

 direct into this school. Even with the open door there was no 

 exit for the air inside to make room for that which wanted to 

 come in from without. The odour was simply sickening. The 

 careless indifference of the people did not seem to promise much 

 appreciation of an effort to give them good ventilation. Still, 

 human nature has an innate desire for warmth on a cold day, 

 and likes to have the miserable results of bad ventilation 

 removed, even although it may not know the cause. Besides, 

 to neglect juvenile humanity is taking upon oneself the unlaw- 

 ful privilege of visiting the sins of the fathers upon the children. 



A new school-room was built. The method adopted for its 

 ventilation was, when building, to have an equal number of 

 ventilators placed in each of the four walls under the floor, to 

 prevent a wind in any one direction affecting the supply of air 

 to the school, by causing a down draft through the stove
