JOHN WESLEY POWELL. 



JOHN WESLEY POWELL was in more senses than one a scien- 

 tific frontiersman. His life reveals the energetic working of a 

 vigorous and independent personality, not trammeled by tradi- 

 tional methods and not so deeply versed in the history, the 

 content, and the technique of the sciences as to be guided by 

 them, but impelled to the rapid discovery of new principles by 

 the inspiration of previously unexplored surroundings. His 

 life shows us further how a man of exceptional power rises 

 suddenly in an otherwise undistinguished lineage, and how he 

 surmounts the limiting associations of early years, less through 

 the opportunity provided by others than through opportunities
