CONSERVATION 



into the soil zt, say, an altitude of 2,000 

 feet, it is plain that this body of water 

 will expend as much energy in getting 

 back to the sea as the sun has expended 

 in lifting it to this height, or as the 

 mechanical devices of men might ex- 

 pend in lifting a million tons 2,000 feet 

 high. But the energy of the sun has al- 

 ready lifted this water, and there it lies 

 of so much potential dynamic value. 

 The question is : How shall we utilize 

 the particular energy which the sun has 

 stored in this particular way, so that 

 we may relieve the too wasteful use of 

 that other particular form of energy 

 which the sun has stored in coal? 



Mr. Roosevelt's solution is simple and 

 laconic : Drive zvheels. This is good 



nation housekeeping; it is, therefore, 

 good politics. 



Herein, I think, lies the greatness of 

 Mr. Roosevelt — that he has all the qual- 

 ifications of a great politician. Of 

 course, when I am speaking of a great 

 politician to an Oxford audience, it will 

 be taken for granted it is in the Aris- 

 totelian and not the American sense. 

 The first qualification is creative imag- 

 ination. This bridges the gap between 

 science and philosophy. Add to this, 

 ethical insight, sanity of judgment, and 

 a daring which knows no bounds save 

 those of righteousness and the common 

 good, and you have the ideal politician, 

 if he also happens to be a scientific 

 geographer.
