CONCLUSIONS 



The facts here given present an explanation of the elevation and 

 depression of the land in the New Madrid region that has not before 

 been recognized, and the writer believes that they form a satisfactory 

 explanation of the phenomena which have so long puzzled those 

 who have attempted to solve the problem of the great local disturb- 

 ance at New Madrid. If this is so, they may also explain similar 

 instances of subsidence and elevation in other regions that have been 

 little understood, and will demonstrate, for the artesian waters of 

 the globe, a wider influence as a geologic agent than has hitherto 

 been ascribed to them.
