GEOLOGY IN EVERYDAY LIFE MANSFIELD 273 



The literary value of its better products is high, its logic and broad 

 philosophies stimulate the mind, and its factual content has world- 

 wide interest. 



SUMMARY 



Geology, through its bearing on supplies of mineral raw materials, 

 necessary adjuncts to our civilization, enters into many relations of 

 local and national importance. The information it supplies is basic 

 to many great industries. It enters also into more intimate human 

 affairs. Truly it may be said that the relation of human life to geology 

 is as close as that of a fish to water. The earth on which we walk, the 

 air we breathe, the water we drink, the daily events of our lives and 

 even our higher endeavors and aspirations, are ordered or affected by 

 geologic phenomena and principles. Though mystery, in the sense 

 of things we can not explain, enters into geology as it does into life 

 itself, its commoner aspects are so clear, so instructive and so enticing 

 if once sensed, that they can hardly fail to appeal to the imagination 

 and interest of any active mind.
