In later life Agassiz made to us some prophecies in which we may

 acquaintance with the world has not in any way dimmed the brightness 

 of that early impression. 



The services of the geologist are today recognized by every one, and 

 sought by all who can afford them. If he would make a voyage of 

 exploration and discovery, the resources of the world of finance are
