134 THE WONDERFUL HOUSE THAT JACK HAS 



work and play, and whose clear brains and ready 

 muscles are able to meet the demands made upon them 

 without nervousness or undue fatigue ? Then let 

 us improve every opportunity of being out-of-doors. 

 In summer we can read on the veranda rather than in 

 the house, and take the open car instead of the closed, 

 when riding is necessary. At any season we can walk 

 whatever distance time and strength will permit, to 

 avoid breathing the close air of a crowded car. In 

 fact, whenever we have a choice of being in or out of 

 doors, we can always let our preference be for the free, 

 bracing air outside. 



When we are in places where the air must necessarily 

 be close, we should avail ourselves of an opportunity to 

 get a few breaths of fresh air as eagerly as we should 

 get a drink of cold water when thirsty. For instance, 

 on a railroad trip, when it is impossible to have the 

 car windows open, we can go to the platform at the 

 stopping places and fill our lungs with the oxygen-laden 

 air from outside. The car sickness and dull feeling 

 that often attend such journeys might thus be greatly 

 lessened. Whether in school, in church, at home, or 

 in business, let us use our influence for a pure air 

 supply, and be just as eager for it as if it were some 

 high-priced elixir. Of this we may be sure : there is 

 no elixir that begins to equal the pure air of heaven.
