Intkoduction 



Hayeses most striking trait was an ability to grasp quickly the elements 

 of a new problem. Trained primarily as a chemist, with the purpose of 

 becoming a teacher, his introduction to geologic field-work was in a region 

 of most complex structure. He soon mastered the problems before him 

 and first became known to the geologic world as a tectonic geologist. 

 Turning from this to physiography, he quickly became a leader in this 

 science. Meanwhile chance opened the field of exploration, and he easily 

 passed from the work of precise mapping to hasty reconnaissance, uiade 

 under most difficult conditions. From tectonics and physiography he 

 turned to varied investigations rehitiug to mineral deposits, only to desert 

 them for researches directed toward tlie solving of problems connected 

 with great engineering works. 



During tlie last fifteen yeais of his life ho was best known as an admin- 

 istrator, fii'st of geologic rosoarcli and then in the business world. In 

 the latter he was confronted with problems which Avould ha\'e baffled a 

 lesser mind. 



The scenes of his personal investigations included as widely separated 

 fields as Central America and the Yukon basin, while the scope of his
