Yol. 55.] ANNIVERSARY ADDRESS OF THE PRESIDENT. IxXxiii 



devoted to science as any one can be. He had just finished a 

 re-survey of a certain district, and very naturally thought that he 

 knew nearly all about that district, when he was obliged to examine 

 it again, for the purposes of an important scheme of water-supply. 

 To his surprise, the looking at things from a point of view different 

 from that to which he had been accustomed brought before him 

 phenomena that he had not noticed previously. He became a wiser, 

 but not a sadder, man. 



Moreover, geologists should have some gratitude for the great 

 amount of information which they obtain from those who are known 

 as practical men, and should show it by making their science avail- 

 able for practical purposes. With geology, as with other studies, 

 not only should theory and practice go hand in hand, but know- 

 ledge, gained from both, should be applied to useful purposes and 

 for the public good.
