ladies and four gentlemen lay dignity aside and 

 obtain relief by jamming into a place barely 

 large enough for two. In my own case, activity 

 invariably intensified these effects; and the 

 touching of steel or iron often had the same 

 results. For some years a family resided upon 

 the slope of Mt. Teller, at an altitude of twelve 

 thousand feet. Commonly during storms the 

 stove and pipe were charged with fluid so heav- 

 ily that it was a case of hands off and let din- 

 ner wait, and sometimes spoil, until the heavens 

 shut off the current. 



The sustaining buoyancy of the air to aerial 

 things decreases with altitude. In this "light'* 

 air some motor machinery is less efficient than 

 it is in the lowlands. It is probable that avia- 

 tors will always find the air around uplifted 

 peaks much less serviceable than this element 

 upon the surface of the sea. But known and 

 unknown dangers in the air will be mastered, 

 and ere long the dangers to those who take flight 

 through the air will be no greater than the 

 dangers to those who go down to the sea in ships.
