310 THE WONDERFUL HOUSE THAT JACK HAS 



body. The lungs are so often the place affected, how- 

 ever, that consumption and tuberculosis of the lungs 

 are generally regarded as the same thing. Who are 

 likely to be attacked by this dread disease ? While no 

 person is immune, and no one can be said to be fated, 

 statistics show that the following are especially vulner- 

 able : persons who work in impure air or where there is 

 much irritating dust ; persons who are narrow-chested 

 or round-shouldered ; persons who do not employ deep 

 breathing; persons who are subject to frequent colds 

 or catarrh ; persons whose ancestors or relatives have 

 had the disease ; persons not well fed or fully nourished, 

 especially those living in dark, poorly ventilated 

 rooms. 



Do we belong to any of these classes? If so, let us 

 be watchful that ours is not one of the deaths credited 

 to this great destroyer. Taking up an out-of-door 

 occupation ; developing our greatest breathing capac- 

 ity; in every way making the best use of food, air, 

 water, exercise, and rest ; even planning to spend life 

 in the most favorable climate, these are among the 

 effective weapons to be employed in our defense. 

 How thankful all should be that having or escaping 

 consumption is not a matter of luck or inheritance, 

 but simply a question of keeping up strength and 

 vitality !
