HOW TO GET FRESH AIR 25 



the room, and not low down where we are sitting; or 

 one window might be open at the top and another open 

 at the bottom. 



In any kind of house a fireplace helps more than 

 anything else to keep the air pure. 



Perhaps you are in a house that is heated in the best 

 way. In such houses the heat comes from steam pipes 

 or hot-water pipes in every room. Besides that, fresh air 

 is heated in the basement and pours into each room 

 through a register. Then too, there is a ventilator or 

 a fireplace in each room and the impure air escapes 

 through these. 



When heating and ventilating are managed in this 

 way nobody need be anxious to open and shut windows, 

 and there is no danger from drafts. 



In your own room to-night decide just what is the 

 best way to supply yourself with fresh air while asleep. 

 Fortunately there is always so much of it out of doors 

 that all we have to do is to give it a chance to get into 

 our rooms. When we let it in by the window at night 

 we must be careful to have bedding enough, and we 

 must never sleep in a draft.
