W J MCGEE OUTLINES OF HYDROLOGY 



motion is undulatory or pulsatory, and in streams it moves extraneous 

 matter in a saltatory way, thereby automatically (or autonomously) ad- 

 justing internal relations continuously to external relations and even- 

 tually adjusting the land surface of the planet to its own movement; in 

 streams, and measurably in lakes and seas, it consists of inert and inelas- 

 tic frictionless particles or modules of variable size, inherently incon- 

 gruous and unstable among themselves, each tending individiially and all 

 tending collectively to move saltatorily in paraboloid paths adjusted to 

 gravity and friction with bed and load; it enters into and forms the 

 greater part of terrestrial organisms, which also adjust internal relations 

 continuously to external relations and tend to direct both internal and 

 external physical processes toward their own perpetuity and toward a pro- 

 gressive control of the terrestrial HoO itself; and through organic frmc- 

 tion it forms a prime requisite for organized intelligence, which contin- 

 ually readjusts internal relations of organic and other materials and 

 powers to the sum of external relations in such manner as to increase its 

 own control over planetary conditions and thereby perpetuate its own 

 existence with that of the organisms and the menstruum on which they 

 alike depend. On these and related elements scientific plans for the 

 utilization and ultimate control of the terrestrial HjO may safely rest; 

 and on these and related scientific plans in turn the hopes of men and 

 nations for their own prosperity and perpetuity may confidently be 

 founded.
